This standard is not applicable to onsite repair at the equipment installation site.
These guidelines outline what local communities and other key stakeholders can expect from operators. Oil and gas operators acknowledge the challenges associated with industry activities, which can include challenges important to a community. Principles of integrity, transparency and consideration for community concerns underpin responsible operations. Conscientious operators are committed to helping communities achieve positive and long-lasting benefits.
Both local stakeholders and operators can use this guidance. It is designed to acknowledge challenges and impacts that occur during the industrys presence in a given region. It provides flexible and adaptable strategies, recognizing that application will vary from operator to operator and community to community. Many operators already apply similar guidelines or processes within their operations. These suggested guidelines are typical and reasonable and generally apply under normal operating circumstances. The use of these guidelines is at each individual operators discretion.
Operators recognize that stakeholders within the community can have different interests, issues and levels of concern. Some of these interests can be in direct conflict with one another. Working together with stakeholders to seek mutually agreeable solutions is an important aspect of community engagement. Operators can have different approaches to addressing the concerns and issues.
These guidelines are intended primarily to support onshore oil and gas projects in the United States for shale developments; however, they can be adapted to any oil and gas projects in the United States.

Pipe modified by cold working after production, such as expandable tubulars and coiled tubing, is beyond the scope of this Technical Report.
Application of performance property equations in this Technical Report to line pipe and other pipe is restricted to their use as casing/tubing in a well or laboratory test, and requires due caution to match the heat-treat process, straightening process, yield strength, etc., with the closest appropriate casing/tubing product. Similar caution should be exercised when using the performance equations for drill pipe.
This Technical Report and the equations contained herein relate the input pipe manufacturing parameters in ISO or API 5CT, ISO or API 5D, and ISO or API 5L to expected pipe performance. The design equations in this Technical Report are not to be understood as a manufacturing warrantee. Manufacturers are typically licensed to produce tubular products in accordance with manufacturing specifications which control the dimensions and physical properties of their product. Design equations, on the other hand, are a reference point for users to characterize tubular performance and begin their own well design or research of pipe input properties.
This Technical Report is not a design code. It only provides equations and templates for calculating the properties of tubulars intended for use in downhole applications. This Technical Report does not provide any guidance about loads that can be encountered by tubulars or about safety margins needed for acceptable design. Users are responsible for defining appropriate design loads and selecting adequate safety factors to develop safe and efficient designs. The design loads and safety factors will likely be selected based on historical practice, local regulatory requirements, and specific well conditions.

As apart of this project, more than110 polished rod dynamometer cards taken with the electronic analog simulator at Midwest Research Institute. These were recognized and presented in catalog from as Summary Report Vol.II of II January 1 December 31, ,M.R.I Project No. -E. Sucker Rod Pumping Research , Incorporated, before its dissolution , released this catalog of cards to the American Petroleum Institute. It was determined by the committee on Standardization of Production Equipment at the Midyear Standardization Conference and reported in Cire PS- dated August, that the catalog would be published by the API Dallas office for the cost of reproduction
Nomenclature is that used in API RP 11L: Recommended Practice for Design Calculations for Sucker Rod Pumping Systems. The cards were derived for many combinations of the independent non dimensional parameters Fo / Skr and N / N6. The cards are published for information and reference.
A discussion of the information presented, including an explanation of the numbers and material on the card sheets, may be found in the following paragraphs. Suggestions for card use are also given. This discussion is included through the courtesy of Mr. M. H. Halderson, Philips Petroleum Company
b. The purposes of issuing these results are: (1) to show the degree of agreement among a representative group of riser analysis computer programs. and (2) to present data which can be used to help validate other such programs.
c. In cases where the results of a participant differed significantly (some 25% or more) from the consistently clustered results of the majority of the participants, results were omitted. Numerous attempts were made by the committee members to assist participants in correcting input errors, problem definitions, and other likely sources of disagreement. The omissions were handled on a problem by problem basis, i.e., the number of solutions used to compile the results for each problem varies. The number of solutions included for each individual problem is indicated throughout the tables and figures in parentheses following the problem designation.
d. None of these results have been directly validated by measurements on equivalent real risers, although some of the programs have been partially validated in other applications. Comparisons such as those described here are not intended to replace or lessen the need for such validation.
e. American Petroleum Institute (API) Bulletins are published to provide information for which there is a broad industry need but which does not constitute either Specifications or Recommended Practices.
f. Any Bulletin may be used by anyone desiring to do so, and a diligent effort has been made by API to assure the accuracy and reliability of the data contained herein. However, the Institute makes no representation, warranty or guarantee in connection with the publication of any bulletin and hereby expressly disclaims any liability or responsibility for loss or damage resulting from its use, for any violation of any federal, state, or municipal regulation with which an API recommendation may conflict, or for the infringement of any patent resulting from the use of this publication.
Common sources of evaporation loss are: a, storage tanksfrom breathing, emptying, filling, or boiling; b, productionfrom gas-oil separation and emulsion treating; c, refiningfrom treating in freely vented vessels, leaky pressure systems, sewers, ponds, and open separators; and d, transportationfrom loading, transit, and unloading of cargo vessels and from pipelines. Also under certain conditions, such as inaccurate measurement of stock movements, a loss appears to have occured when actually there is none.
The rate of evaporation loss depends upon several factors. True vapor pressure is the force causing vaporization and, generally, loss is considered to be more or less directly proportional to it. Atmospheric and solar-heat changes cause the tank vapor space to breathe, and vapor-space volume affects the amount of breathing. Loss rate probably is less than directly proportional to vapor volume and daily atmospheric-temperature change.
For storage of petroleum and its products, the industry can choose from four basic types of tanks, fixed-roof, floating-roof, variable-vapor-space, and pressure. Each design meets specific storage needs. Selecting the most economical tank often requires careful study of the different types. For each tank, effective loss control depends upon accessories such as breather valves and automatic gages. To maintain effective control, the tank and accessories must be kept gastight. Choice of paint color is also an important factor.
The operating procedures used in production, refining, transportation, and marketing are all important in controlling evaporation loss. Prevention of leaks from glands, valves, and fittings should be common to all branches of the industry. In production, control of temperature in the gas-oil separators and in the emulsion-treating equipment is necessary. In refining, operation of treating plants, sewers, ponds, and open separators require special consideration. In transportation, careful scrutiny of the methods for loading and unloading is essential.
Control of evaporation loss requires that continued attention be given to operating procedures and maintenance of equipment. Conservation equipment sometimes becomes less effective with age and an evaluation frequently reveals that modernization would pay. These factors demonstrate the need for organized programs for loss control. Only in this way will the necessary concerted attention be given this important subject.
Fixed structures include steel jacket or template platforms, towers and compliant towers, caissons, minimum non-jacket and special structures that are fixed to the seafloor. Design of these structures generally follows API 2A-WSD guidelines.
Floating structures include tension leg platforms (TLPs), spars, deep draft caisson vessels, semi-submersibles and any other type of floating or tethered structures. Design of these structures generally follows API 2T, API 2FPS, API 2SK, API 2RD and API 2I guidelines.
Post-hurricane structural inspections are not as comprehensive as, or supplant the need for, regular in-service inspections as may be detailed in the structure's in-service inspection plan (ISIP).
This document describes post-hurricane structural inspection of structures designed in accordance with the following API documents:
API 2A-LRFD,
API 2A-WSD
API 2FPS,
, API 2I,
API 2RD,
API 2SK,
API 2T,
API 2TD.
These structures may also be designed and operated in accordance with regulatory and classification society guidelines and these should be applied as required.
1.2Wildcats are of the five-whelp type for use with stud link anchor chain conforming to the classification society grades 1, 2 and 3, ORQ and Grade 4 chain. Wildcat dimensions are provided for chains in integral Vs-in. (3-mm) steps, ranging in size from 2 in. to 4 in. (51 mm to 102 mm). Wildcat dimensions for chain in intermediate Vi6 in. (1.5 mm) steps are not provided, but wildcats in these sizes are permitted within the scope of this publication. Wildcats designed in millimeters must be compatible with chain manufactured in millimeters. Wildcats designed in inches must be compatible with chain manufactured in inches.

1.1.2 The buckling capacities of the cylinders are based on linear bifurcation (classical) analyses reduced by capacity reduction factors which account for the effects of imperfections and nonlinearity in geometry and boundary conditions and by plasticity reduction factors which account for nonlinearity in material properties. The reduction factors were determined from tests conducted on fabricated steel cylinders. The plasticity reduction factors include the effects of residual stresses resulting from the fabrication process.
1.1.3 Fabricated cylinders are produced by butt-welding together cold or hot formed plate materials. Long fabricated cylinders are generally made by butt-welding together a series of short sections, commonly referred to as cans, with the longitudinal welds rotated between the cans. Long fabricated cylinders generally have D/t ratios less than 300 and are covered by AP RP 2A.
2.1.2 Flat plate structures include thin plates, stiffened panels and deep plate girders, and they can constitute the main component of decks, bulkheads, web frames and flats. The external shell of pontoons or columns can also be made of flat stiffened panels if their cross section is, for example, square or rectangular, rather than circular.
2.1.3 Bulletin 2V is not a comprehensive document, and users have to recognize the need to exercise engineering judgment in actual applications, particularly in the areas that are not specifically covered.
2.1.4 Plates are discussed in Section 3, stiffeners in Section 4, stiffened panels in Section 5, and deep plate girders in Section 6. Limit states are given for each relevant load and load combination, and design requirements are also defined. Figure 2.1-1 summarizes the structural components and the limit states covered in Bulletin 2V.

Radiation can result from both man-made and natural sources. Man-made sources include dental x-rays and well logging tools. Natural sources of radiation include the sun (cosmic rays) and radiation from naturally occurring materials found in the earth's crust and in living organisms. Radioactive materials are unstable and decay over time, emitting ionizing radiation. If body tissue or organs are exposed to excessive radiation, biological damage can occur in the individuals exposed or in their descendants, increasing the risk of cancer or birth defects. Thus, it is important to protect humans from unnecessary exposure to excessive levels of radiation.
NORM is found throughout the natural environment and in man-made materials such as building materials and fertilizer, as well as in association with some oil and gas production. NORM found in oilfield operations originates in subsurface oil and gas formations and is typically transported to the surface in produced water. As the produced water approaches the surface and its temperature drops, precipitates form in tubing strings and surface equipment. The resulting scales and sludges may contain radium and radium decay products as well as other uranium and thorium progeny. In addition, radon is sometimes contained in produced natural gas and can result in the formation of thin radioactive lead films on the inner surfaces of gas processing equipment.
Measurements on the outer surfaces of equipment containing NORM usually indicate levels of radiation that are below levels considered to be of concern. When equipment is opened for inspection or repair, inhaling or ingesting NORM can expose personnel to radioactivity. Therefore, in these situations, workers should take precautions to prevent the generation of dust and wear protective equipment. It is also important that NORM waste or equipment containing NORM be managed and disposed by methods that protect the public from unnecessary exposure.
Control Issue Group (UICIG), provides guidance on environmentally-sound abandonment practices for wellbores drilled for oil and gas exploration and production (E&P) operations. The guidance is focused primarily on onshore wells. Guidance is provided for the practices that may be used and for the selection and placement of materials necessary to accomplish the following:
Permanently abandon wells.
place web on inactive status.
Permanent abandonment should be performed when there is no further utility for a wellbore by sealing the wellbore against fluid migration. Inactive well practices may be performed when a wellbore has future utility, such as for enhanced oil recovery projects. This permits the operator to hold the well in a condition that facilitates restoring its Utility.
The purpose of this document is to address the environmental concerns related to well abandonment and inactive well practices. The primary environmental concerns are protection of freshwater aquifers b m fluid migration, as well as isolation of hydrocarbon production and water injection intervals. Additional issues discussed herein are protection of surface soils and surface waters, future land use, and permanent documentation of plugged and abandoned (P&A) wellbore locations and conditions.
The guidance contained in this document is presented by the following process:
1. Discussing a methodology for assessing the contamination potential of wells.
2. Describing the environmental concerns that justify proper wellbore abandonment procedures.
3. Describing permanent plugging and abandonment procedures.
4. Establishing risk based guidelines for monitoring inactive wells.
5. Summarizing major environmental legislation and associated regulations applicable to wellbore abandonments.
API encourages use of well abandonment practices based on the methods presented in this document. API also supports any Federal and state well abandonment programs consistent with its guidance. There are numerous Federal and state statutes, rules, and regulations specifying proper well abandonment practices. Users of this document should review the current requirements of Federal, state, and local regulations to ensure that this guidance is consistent with those regulatory requirements.
The information in this document is general in nature. Wellbore plugging and abandonment practices will vary with regulation, well type, and purpose. Sound engineering and operational practices should be applied to each plugging operation. Plug lengths are not considered in this document. Local regulations must be considered in the design as they may dictate the length of cement to be placed below or above specific intervals, or both.
Presently the federal government provides a framework for watershed management programs though the creation of potential funding sources, technical assistance, and water resource regulations. In order to carry our these regulations, the federal government delegates water resource management to individual states. State agencies in conjunction with regional and local institutions are often a mechanism for implementing projects within individual watersheds. On occasion local watershed agencies enact site-specific regulations in deal with localized problems, while still abiding by state and federal water laws. The distribution of authority between federal, state, and local agencies allows management programs to focus on problems unique to individual watersheds. Currently, a multitude of watershed management institutions exist throughout the country, many of which are not mandated by federal law.
If future CWA legislation were to further encourage the application of watershed management techniques nationwide, all sectors of society would be affected. In order to understand the current status of watershed management in the US and the operational structure of active watershed programs, this paper reviews watershed approaches, both in theory and practice, and utilizes a case study approach of individual watershed programs and institutions. Details of individual case studied are organized under the following eight headings: introductory remarks; general characteristics; water quality problems; implementation factors - authority and funding; program infrastructure; non point source pollution (NPS) management programs, petroleum related activity; and program accomplishments.
Wetlands contribute much to society. They provide a habitat for fish, birds, and other wildlife, contributing to biodiversity in the process. The perform hydrologic functions (e.g., flood peak reductions, shoreline stabilization, ground water recharge) and improve water quality through sediment accretion and nutrient uptake (National Research Council, ). Additionally, they provide society with areas for recreation and research. However, since most of the benefits of leaving a wetland in its natural state flow to the public at large, and not the landowner, there exists significant pressure for landowners, (who one 74 percent of all remaining wetlands, CEQ, ) to convert their wetlands to upland habitat suitable for agriculture, silviculture, and development. Therefore, it is not surprising that over half of the countrys initial 200 million wetland acres have been converted to other landscapes (Frayer et al., ). Eighty-seven percent of all wetland losses between and were the result of agricultural activity. Urban development activities accounted for and additional 8 percent of losses and all other causes, including natural processes (particularly subsidence and compaction in the Gulf of Mexico coastal wetlands), accounted for the remaining 5 percent of wetland losses (Tiner, ).
A general outcry over wetlands loss prompted state and federal legislators and regulators to address the problem. The most significant pieces of federal wetlands legislation is section 404 of the Clean Water Act, which general requires individuals to obtain a permit from the Army Corp of Engineers (Corps) before filling wetlands. Obtaining a permit requires the applicant to prove that there are no alternative locations for development activity, prove that wetland losses are minimized, and provide compensation for the remaining unavoidable losses by restoring, enhancing, creating, or ( in limited cases) preserving wetlands.
In fact, the available empirical evidence suggests just the opposite -- by most measures, world oil resources are more abundant today than ever before. World production in recent years has resumed the growth that was briefly interrupted in the 70s and early 80s (though at a lower rate), as seen in Figure 1.
World production rose more than sixfold between and its peak in (at nearly 63 million barrels a day). After a sharp decline in the first half of the 80s attributable to the Iran/Iraq war and an ultimately futile attempt by OPEC to defend an unrealistic price, supply began growing again after , averaging about 1.4% per year since that time, and is expected to soon surpass the previous peak.
Despite this massive expansion of supply, there is little evidence of the effects of depletion available in the historical record. As seen in Figure 2, in proven reserves were 90 billion barrels, sufficient to sustain production at the rate for about 24 years. By , reserves had expanded to nearly a trillion barrels, sufficient to support levels of production for another 45 years. Moreover, this more than tenfold expansion of proven reserves occurred despite the fact that 650 billion barrels had been consumed in the interim. However, there may be less here than meets the eye.
Proven reserves do not, have not, and were never intended to provide a measure of remaining resources, or even an approximation to such a measure. Rather, they are and always have been defined to represent a working inventory, continually replaced by new exploration and development. Current reserve estimates no more represent the remaining supply of oil resources than current inventories of groceries on the shelf are a measure of future food supplies3. Nonetheless, the level of proven reserves at any point does say something about future supply potential. Namely, it generally provides a lower bound on remaining resource potential4, rather than the upper bound it is often misinterpreted to represent
That upper bound, the amount of oil remaining in the earth, is clearly finite and, unlike proven reserves, clearly declines with cumulative production. However, its magnitude is unobservable, and more importantly, it is not clearly even relevant to the imminence of exhaustion. That is, oilfields are typically abandoned far before the oil in place is completely removed. On average, only about a third of the oil is recovered at the point where it typically becomes technically or economically impractical to continue production.
This paper examines a part of the historical record on the use of benefit-cost analysis in the federal government regulator arena. The purpose of this examinations to learn what has and has not been done with past analyses, what kinds of analyses are feasible, and most importantly, what is necessary to male good use of economic criteria in regulatory decision making.
Am additional question is , if services are the focus of restoration, what services should be addressed? Should it be all services , regardless of whether humans place any value on them, or should it be limited to human services- those services that the public cares about? The regulations appear to require the restoration of all services, arguing that ecological services are generally linked to those things the public cares about.
Depending on which objectives are chosen, large quantities of productive resources could be consumed in activities that would generate few, if any, commensurate public benefits.

It is anticipated that the use of ethanol in motor fuels will continue to increase. This has generated interest about the potential long-term structural effects of ethanol on liquid petroleum storage systems, including underground storage tanks (USTs), underground piping, and associated components.
The objective of the literature review is to determine the state of industry knowledge and research on the effects of ethanol/gasoline blends on the long-term structural integrity of UST systems and components. This review is intended to assist decision-makers on further research requirements and needed changes or supplements to existing standards for underground storage systems and components used for storing and dispensing gasoline blended with ethanol.

This standard defines the test methods including the generation of unfoamed base and their corresponding foamed cement slurries at atmospheric pressure. These procedures are developed for foaming cement slurries with air, at atmospheric conditions, which could mimic a foam quality experienced with nitrogen at downhole conditions; they may be modified to accommodate other gases such as nitrogen. Slurries that are foamed with nitrogen, and their properties, will also be discussed within this standard as they are relevant to the scope of the standard.
This standard does not address testing at pressures above atmospheric conditions, nor does this standard include or consider the effects of nitrogen solubility in the nitrogen fraction calculations.

The basic walking-beam sucker rod combination for producing fluids from the ground had its beginning in very early history. In more recent times, many advances in design and metallurgy have evolved. The method is so popular that today approximately 90 percent of all artificially lifted wells are produced by a sucker rod pump.
The downhole sucker rod pump is only one portion of the pumping system.The other major components are the sucker rod string, the surface pumping unit and the prime mover. For proper pumping operation and long maintenance-free runs, all components of the system must be designed and sized properly, taking into account well depth, the amount and viscosity of fluids (oil, water or gas) to be produced, and abrasiveness and corrosiveness of fluids. A failure of any one of the pumping components will result in a shut down of the system, resulting in a costly repair, downtime and possible loss of production.

a) These safeguards should prevent bodily injury from contact with moving parts by anyone inadvertently walking into, falling, slipping, tripping, or similar action. The safeguards should also prevent injury from reasonable or predictable breakage of any of the component parts.
b) It is anticipated that persons who will be exposed to the hazards involved with the moving parts of a pumping unit are adults who are able-bodied and physically capable of performing useful work; they may be expected to be of normal intelligence and able to act with reasonable decorum and caution. They may also be expected to be aware of the potential hazards involved. The general public normally will not have access to the area where pumping units are located. Pumping units generally are in rural and fairly remote locations on private leases where the public would be trespassing.
c) Where unattended locations present close exposure to a community of people, safety barriers, such as provided by a totally enclosed and locked perimeter, may be required.
This recommended practice provides guidance related to the proper installation, care, and maintenance of surface mounted beam pumping units, varieties of which are described in API 11E. Information provided in this document is of a general nature and is not intended to replace specific instruction provided by the pumping unit manufacturer. This document further establishes certain minimum requirements intended to promote the safe installation, operation, and servicing of pumping unit equipment.

These recommended practices discuss continuous gas-lift with injection in the casing/tubing annulus and production up the tubing. Annular flow gas-lift (injection down the tubing and production up the annulus), dual gas-lift (two tubing strings in the same casing), and intermittent gas-lift are mentioned; however, most of the discussion focuses on conventional continuous gas-lift. Many of the recommended practices in this document may be pertinent to the other forms of gas-lift, but they should be considered and used with caution. Other recommended practices will address dual gas-lift (API 11V9) and intermittent gas-lift (API 11V10).

These sections are new to this edition of the document. A comprehensive checklist of system components is provided and associated problems are discussed. The list can be used when troubleshooting or de-bottlenecking a gas-lift system.
These sections are recommended for use as:
part of a training course dealing with gas-lift system operation;
a review before beginning a major gas-lift system study;

Annular flow gas-lift (injection down the tubing and production up the annulus), dual gas-lift (two tubing strings in the same casing), and intermittent gas-lift are mentioned; however, most of the discussion focuses on "conventional" continuous gas-lift. Many of the recommended practices in this document may be pertinent to the other forms of gas-lift, but they should be considered and used with caution. Other recommended practices will address dual gas-lift (API 11V9) and intermittent gas-lift (API 11V10).
The injection gas pressure operated (IPO) bellows valve is one example of a commonly repaired valve; the spring loaded production pressure operated (PPO) valve is also covered. Other valves, including bellows charged valves in production pressure operated service should be repaired according to the guidelines, however specialty valves are best repaired at the original manufacturer's shop.

Introduction to Gas Lift System Design and Performance Prediction
API RP 11V8 Recommended Practice for Gas Lift System Design and Performance Prediction, provides two functions:
A broad overview of gas lift systems and various major types of gas lift operations.
Recommended practices for gas lift system design and for modeling methods used in performance prediction. All key system components are reviewed to provide guidance for engineers, technicians, well analysts, and operating personnel who are involved in gas lift system analysis, troubleshooting, design, and optimization.
The primary purpose of this API Recommended Practice (RP) is to emphasize gas lift as a system and to discuss methods used to predict its performance. Information must be gathered and models validated prior to a system design, which must precede wellbore gas lift mandrel and valve design. The subsurface and surface components of the system must be designed together to enhance the strengths of each and to minimize the constraints.
This recommended practice bridges and enhances the general information from the API Gas Lift Manual (Book 6 of the Vocational Training Series) and the technical details of other API Gas Lift RPs, each of which contain information on a specific subject or part of the overall gas lift system. The gas lift system designer or operator should have and become familiar with the full set of documents from the API (American Petroleum Institute), GPSA (Gas Processors Suppliers Association), and ISO (International Standards Organization) that relate to gas lift system components:

1.2 The target audience for this RP covers both the office and wellsite engineer. The complexity of the equations used is such that a competent engineer can use a simple spreadsheet program to conduct the analyses. Given that the equations used herein are constrained by the spreadsheet limitation, more advanced numerical solutions containing multiple subroutines and macros are not offered. This limitation does not mean that only the results given by the spreadsheet methods are valid engineering solutions.
1.3 Rheology is the study of the deformation and flow of matter. Drilling fluid hydraulics pertains to both laminar and turbulent flow regimes. The methods for the calculations used herein take into account the effects of temperature and pressure on the rheology and density of the drilling fluid.
1.4 For this RP, rheology is the study of flow characteristics of a drilling fluid and how these characteristics affect movement of the fluid. Specific measurements are made on a fluid to determine rheological parameters under a variety of conditions. From this information the circulating system can be designed or evaluated regarding how it will accomplish certain desired objectives.
1.5 The purpose for updating the existing RP, last published in May , is to make the work more applicable to the complex wells that are now commonly drilled. These include: High-Temperature/High-Pressure (HTHP), Extended-Reach Drilling (ERD), and High-Angle Wells (HAW). Drilling fluid rheology is important in the following determinations:
a) calculating frictional pressure losses in pipes and annuli,
b) determining equivalent circulating density of the drilling fluid under downhole conditions,
c) determining flow regimes in the annulus,
d) estimating hole-cleaning efficiency,
e) estimating swab/surge pressures,
f) optimizing the drilling fluid circulating system for improved drilling efficiency.
1.6 The discussion of rheology in this RP is limited to single-phase liquid flow. Some commonly used concepts pertinent to rheology and flow are presented. Mathematical models relating shear stress to shear rate and formulas for estimating pressure losses, equivalent circulating densities and hole cleaning are included.
1.7 The conventional U.S. Customary (USC) unit system is used in this RP.
1.8 Conversion factors and examples are included for all calculations so that USC units can be readily converted to SI units. Where units are not specified, as in the development of equations, any consistent system of units may be used.
1.9 The concepts of viscosity, shear stress, and shear rate are very important in understanding the flow characteristics of a fluid. The measurement of these properties allows a mathematical description of circulating fluid flow. The rheological properties of a drilling fluid directly affect its flow characteristics and all hydraulic calculations. They must be controlled for the fluid to perform its various functions.
1.10 This revised document includes some example calculations to illustrate how the equations contained within the document can be used to model a hypothetical well. Due to space constraints, it has not been possible to include a step-by-step procedure for every case. However, the final results should serve as a benchmark if the user wishes to replicate the given cases.
1.2 Office and wellsite engineers are the target audience for this document. The complexity of the equations provided is such that a competent engineer can use simple spreadsheet programs to conduct analyses. Given that the equations used herein are constrained by this spreadsheet limitation, more advanced numerical solutions containing multiple subroutines and macros are not offered. This limitation does not suggest that only the results given by the spreadsheet methods are valid engineering solutions.
1.3 Rheology is the study of the deformation and flow of matter. For this document, rheology is the study of the flow characteristics of drilling fluids and how these characteristics affect movement of the fluids. The discussion of rheology in this document is limited to single-phase liquid flow.
1.4 Rheological properties directly affect flow characteristics and hydraulic behavior. Properties must be controlled for drilling fluids to perform their various functions. Certain properties are measured at the wellsite for monitoring and treatment and in the laboratory for development of new additives and systems, formulation for specific applications, and diagnosis of special problems.
1.5 Measurement of rheological properties also makes possible mathematical descriptions of circulating fluid flow important for the following hydraulics-related determinations:
a) calculating frictional pressure losses in pipes and annuli,
b) determining equivalent circulating density (ECD) of the drilling fluid under downhole conditions,
c) determining flow regimes,
d) estimating hole-cleaning efficiency,
e) estimating swab/surge pressures, and
f) optimizing the drilling fluid circulating system to improve drilling efficiency.
1.6 The concepts of viscosity, shear stress, and shear rate are important in understanding the flow characteristics of fluids. Specific measurements are made on fluids to determine rheological parameters under a variety of conditions. From this information, the circulating system can be designed and evaluated to accomplish desired objectives.
1.7 Drilling fluid hydraulics involves hydrostatic pressures, frictional pressure losses, carrying capacity, swab/surge pressures, and equivalent static and circulating densities, among others. Mathematical models relating shear stress to shear rate and formulas for estimating drilling fluid hydraulics are included. Calculation methods used herein consider the effects of temperature and pressure on drilling fluid rheology and density.
1.8 The U.S. customary (USC) unit system is used in this RP. However, any consistent system of units may be used where so indicated, as in the development of equations in Section 4. The term pressure means gauge pressure unless otherwise noted. NOTE The term consistent units refers to a set of units that does not require an extra conversion factor to complete a calculation. In consistent International System of units (SI unit), time is expressed in seconds (s), length in meters (m), mass in kilograms (kg), force in newtons (N), temperature in degrees Celsius (°C), and absolute temperature in kelvins (K).In USC units , time is expressed in seconds (s), length in feet (ft), mass in pound mass (lbm), force in pound force (lbf), temperature in degrees Fahrenheit (°F), and absolute temperature in degrees Rankine (°R).
1.9 Factors included in Section 3, Table 2 permit conversions of USC units to SI units or SI units to USC units.
1.10 Annexes A through F contain example calculations to illustrate how equations contained within the document can be used to model a sample well. Step-by-step procedures are not included for every case; however, final results serve as benchmarks to replicate given cases.

1.2 A list of some minerals commonly associated with barite ores is given in Table 1 with the chemical formulas, mineralogical names, and the densities of the mineral grains.
1.3 The performance of barite in a drilling fluid is related in part to the percentage and type of non-barite minerals distributed in the barite ore. Some of these minerals have little or no effect on drilling fluid properties, but others can degrade these properties and even be harmful to rig personnel.
1.4 It is the objective of this publication to provide a comprehensive, detailed description of the chemical analytical procedures for quantitatively determining the mineral and chemical constituents of barite. These procedures are quite elaborate and will normally be carried out in a well-equipped laboratory.

installing, and testing a basic surface safety system on an offshore production platform. The basic concepts of a platform safety system are discussed and protection methods and requirements of the system are outlined.
This recommended practice illustrates how system analysis methods can be used to determine safety requirements to protect any process component. Actual analyses of the principal components are developed in such a manner that the requirements determined will be applicable whenever the component is used in the process. The safety requirements of the individual process components may then be integrated into a complete platform safety system. The analysis procedures include a method to document and verify system integrity. A uniform method of identifying and symbolizing safety devices is presented and the analysis method is exemplified by a sample process system.
In addition to the basic surface safety system, this recommended practice covers ancillary systems such as pneumatic supply and liquid containment. Procedures for testing common safety devices are presented with recommendations for test data and acceptable test tolerances.
This recommended practice emphasizes pneumatic systems since they are the most commonly used; however, the same principles and procedures are applicable to hydraulic and electrical systems and to systems incorporating two or more control media. Instrumentation logic circuits are not discussed since these should be left to the discretion of the designer as long as the recommended safety functions are accomplished. Rotating machinery is considered in this recommended practice as a unitized process component as it interfaces with the platform safety system. When rotating machinery (such as a pump or compressor) installed as a unit consists of several process components, each component can be analyzed as prescribed in this recommended practice.

1.1.3 Advantages of area classification using zones are as follows.
1.1.3.1 Often, particularly for new installations and for installations that are subject to upgrade or revision, it is advantageous to classify locations as Zones in accordance with Article 505 of the NEC versus Divisions as per Article 500. These advantages may include reduced initial capital expenditures, enhanced safety, or facilities that are more easily and more economically maintained.
1.1.3.2 In the Zone classification system, locations classified as Division 1 in the Division classification system can now be classified and further divided into Zone 0 and Zone 1 locations. Electrical equipment suitable for Zone 1 locations is not required to be suitable for locations where flammable gases and vapors may be present continuously or for long periods of time, i.e. Zone 0 locations. Thus, the protection techniques for equipment to be installed in Zone 1 locations can be less demanding than the protection techniques for equipment to be installed in Division 1 locations. This may result in more cost effective installations or equipment that is more easily maintained.
1.1.3.3 Due to the application of increased safety (protection Type e) equipment, fewer field-installed sealing fittings are required for Zone 1 and Zone 2 equipment than for Division 1 and Division 2 equipment. Fewer field-installed sealing fittings reduce the chance for installation errors, enhancing safety. Much of the equipment approved for Zone 1 and Zone 2 uses plastics (versus metals), reducing corrosion, which can result in reducing maintenance costs and enhancing safety. Also, since the most hazardous locations (Zone 0 locations) are identified, such locations can be avoided for the installation of most electrical equipment. This also can enhance safety.

This document provides the requirements for the design, manufacture, and testing of intervention workover control system (IWOCS) equipment. Blowout prevention (BOP) control systems are outside the scope of this Recommended Practice and typically are not connected to the IWOCS.
Some requirements in this document are specific to the execution of end userdefined safety functions. It is the end users responsibility to define the safety functions (i.e. timed sequence of events to operate a safety class device) as an input to this document. This document defines safety class control functions used to operate safety class devices. Annex A provides guidance on the determination of safety class control functions based on the end userprovided safety functions.
This document identifies the IWOCS equipment typically used in a thru-blowout preventer intervention riser system (TBIRS) and an open-water intervention riser system (OWIRS); see API 17G for more details on these systems and associated components. The IWOCS equipment described in this document may be used for other system types. Table 1 lists equipment typically controlled by an IWOCS. Refer to Figure 1 and Figure 2 for example IWOCS block diagrams for both system types.
IWOCS equipment may be configured in one of the control system architectures listed below. It is not the intent of this document to mandate the type of control system architecture used for a given application.
The IWOCS equipment may be deployed using one of the methods listed below (see Figure 3 for typical deployment methods). It is not the intent of this document to mandate the type of deployment method used. All normal class and safety class control functions (see 3.1.8 and 3.1.12, respectively) need to conform to the requirements given within this document regardless of deployment method.
This document does not cover manned intervention, internal wellbore intervention, internal flowline inspection, tree running, and tree running equipment. However, all the related subsea remotely operated vehicle/remotely operated tool (ROV/ROT) interfaces are covered by this standard.

It is applicable to the selection, design, and operation of ROTs and ROVs including ROV tooling, hereafter defined in a common term as subsea intervention systems.
API Recommended Practice 17H provides recommendations for development and design of remotely operated subsea tools and interfaces on subsea production systems to maximize the potential of standardizing equipment and design principles.
This document does not cover manned intervention, internal wellbore intervention, internal flowline inspection, tree running and tree running equipment. However, all the related subsea ROV/ROT/AUV interfaces are covered by this standard. It is applicable to the selection, design and operation of ROTs, ROVs and AUVs including ROV tooling, hereafter defined as subsea intervention systems.
This Recommended Practice (RP) provides functional requirements and guidelines for ROV/ROT/AUV interfaces in subsea production fields for the petroleum and natural gas industries. It is applicable to both the selection and use of ROV/ROT/AUV interfaces related to subsea production equipment and provides guidance on design as well as the operational requirements for maximizing the potential of standardized equipment and design principles. This RP identifies the issues to be considered when designing for ROV/ROT/AUV operations to interact with (or near) subsea production systems. The framework and specifications set out enables the user (whether they may be on the ROV/ROT/AUV side or production facility side) to design the appropriate interface for a specific application. These interfaces include subsea docking, recharging, data transfer, data harvesting, and mechanical intervention.
It is anticipated that in the future, resident ROVs/AUVs near the seabed can provide high value for oil and gas inspection, monitoring, and maintenance and repair activities. The benefits of employing ROVs/AUVs in such situations include reduced operating costs and improved safety. The guidelines established in this RP leads to efficient development and deployment of ROV/ROT/AUV systems, providing clarity for operators, contractors, and developers. Recommendations have been provided in a flexible manner to accommodate a wide variation of AUV styles and applications, while maintaining an appropriate level of interface commonality for specification.
This document defines four major categories of hot stabs and describes the geometry to maintain compatibility across all manufacturers. The categories were first introduced in Technical Report 17TR15 which described several common or previously used hydraulic hot stab and receptacle configurations. The approach is to ensure backward compatibility of the hot stabs described in API Recommended Practice 17H, 2nd Edition and to align API RP 17H with API S53 and API 16D.
This RP is not intended to replace sound engineering judgment as to when and where its provisions are to be used. Users need to be aware that additional or differing details may be required to meet a specific service or local legislation.
This document is not intended to deter the development of new technology. The intention is to facilitate and complement the decision processes, and the responsible engineer is encouraged to review standard interfaces and re-use intervention tooling in the interests of minimizing life-cycle costs and increasing the use of proven interfaces.
This Recommended Practice presents the current best practice for design and procurement of ancillary equipment, and gives guidance on the implementation of the specification for standard flexible pipe ancillary products. In addition, this Recommended Practice presents guidelines on the qualification of prototype products.
The applicability relating to a specific item of ancillary equipment within this Recommended Practice is stated at the beginning of the section dedicated to that item of ancillary equipment.
This Recommended Practice applies to the following flexible pipe ancillary equipment:
bend stiffeners;
bend restrictors;
bellmouths;
buoyancy modules and ballast modules;
subsea buoys;
tethers for subsea buoys and tether clamps;
riser and tether bases;
clamping devices;
piggy-back clamps;
repair clamps;
I/J-tube seals;
pull-in heads/installation aids;
connectors;
load-transfer devices;
mechanical protection;
fire protection.
This document may be used for bonded flexible pipe ancillary equipment, though any requirements specific to these applications are not addressed. Where relevant, the applicability of recommendations to umbilicals is indicated in the applicability section for the ancillary equipment in question.
This Recommended Practice does not cover flexible pipe ancillary equipment beyond the connector, with the exception of riser bases and load-transfer devices. Therefore this document does not cover turret structures or I-tubes and J-tubes, for example. In addition, it does not cover flexible pipe storage devices, for example reels.
This Recommended Practice is intended to cover ancillary equipment made from several material types, including metallic, polymer and composite materials. It may also refer to material types for particular ancillary components that are not commonly used for such components currently, but may be adopted in the future.
This Recommended Practice applies to ancillary equipment used in association with the flexible pipe applications listed in Section 1 of API 17J:; API 17K: and in API 17B.
demands large capital investments and significant operational expenditures. The value of using subsea technology depends on its production availability (see 3.17) which is a reflection of its reliability and maintainability (RM).
This API recommended practice (RP) aims to provide operators, contractors and suppliers with guidance in the application of reliability techniques to subsea projects within their scope of work and supply only. It is applicable to:
standard and non-standard equipment,
all phases of projects from feasibility studies to operation.
This RP does not prescribe the use of any specific equipment or limit the use of any existing installed equipment or indeed recommend any action, beyond good engineering practice, where current reliability is judged to be acceptable. It is also not intended to replace individual company processes, procedures, document nomenclature or numbering; it is a guide. However, this RP may be used to enhance existing processes, if deemed appropriate.
Users of this RP should gain a better understanding of how to manage an appropriate level of reliability throughout the life cycle of their subsea projects. Industry wide, users should be able to:
recognize the trade off between up front reliability and engineering effort vs. operational maintenance effort,
provide better assurance of future performance of subsea systems,
effectively manage the risks from using novel equipment and standard equipment in novel applications,
schedule projects with sufficient time to address all the technical risks.
Overall, this should lead to better understanding of technical risk and, therefore, greater confidence in economically or technically challenging developments.
Furthermore, this RP provides the industry with a common framework and language, compatible with ISO , Petroleum, petrochemical and natural gas industriesProduction assurance and reliability management, for the specification and demonstration of reliability achievement between operators, contractors, and suppliers.
Reliability is a topic which is best addressed through industry wide cooperation in terms of best practice, managing failures that do occur and the collection and analysis of performance data. This RP aims to provide a starting point for developing common understanding and cooperative progress within the subsea oil and gas industry.
The achievement of improved subsea equipment availability requires good engineering and management processes, practices and behaviors at an organizational level to manage and minimize the potential for equipment failure.
The focus of this RP however, is on specific activities (or tasks) that can be implemented within projects to achieve immediate and tangible improvements to system performance.

Overall, this should lead to better understanding of technical risk and, therefore, greater confidence in economically or technically challenging developments.
Furthermore, this RP provides the industry with a common framework and language, compatible with ISO , Petroleum, petrochemical and natural gas industriesProduction assurance and reliability management, for the specification and demonstration of reliability achievement between operators, contractors, and suppliers.
Reliability is a topic which is best addressed through industry wide cooperation in terms of best practice, managing failures that do occur and the collection and analysis of performance data. This RP aims to provide a starting point for developing common understanding and cooperative progress within the subsea oil and gas industry.
The achievement of improved subsea equipment availability requires good engineering and management processes, practices and behaviors at an organizational level to manage and minimize the potential for equipment failure.
The focus of this RP however, is on specific activities (or tasks) that can be implemented within projects to achieve immediate and tangible improvements to system performance.
This API recommended practice (RP) aims to provide operators, contractors and suppliers with guidance in the application of reliability techniques to subsea projects within their scope of work and supply only. It is applicable to:
standard and non-standard equipment,
all phases of projects from feasibility studies to operation.
This RP does not prescribe the use of any specific equipment or limit the use of any existing installed equipment or indeed recommend any action, beyond good engineering practice, where current reliability is judged to be acceptable. It is also not intended to replace individual company processes, procedures, document nomenclature or numbering; it is a guide. However, this RP may be used to enhance existing processes, if deemed appropriate.
Users of this RP should gain a better understanding of how to manage an appropriate level of reliability throughout the life cycle of their subsea projects. Industry wide, users should be able to:
recognize the trade off between up front reliability and engineering effort vs. operational maintenance effort,
provide better assurance of future performance of subsea systems,
effectively manage the risks from using novel equipment and standard equipment in novel applications,
schedule projects with sufficient time to address all the technical risks.
Overall, this should lead to better understanding of technical risk and, therefore, greater confidence in economically or technically challenging developments.

This recommended practice (RP) presents recommendations for designing, installing, and testing a process safety system for subsea applications. The basic concepts of subsea safety systems are discussed and protection methods and requirements of the system are outlined.
For the purposes of this RP, subsea system includes all process components from the wellhead (and surface controlled subsurface safety valve [SCSSV]) to upstream of the boarding shutdown valve. For gas injection, water injection, and gas lift systems, the shutdown valve is within the scope of API 17V. This also includes the chemical injection system. Refer to Figure 1.
This document is a companion document to API 14C, which provides guidance for topsides safety systems on offshore production facilities. Some sections of this document refer to API 14C for safety system methodology and processes. This RP illustrates how system analysis methods can be used to determine safety requirements to protect any process component. Actual analyses of the principal components are developed in such a manner that the requirements determined will be applicable whenever the component is used in the process. The safety requirements of the individual process components may then be integrated into a complete subsea safety system. The analysis procedures include a method to document and verify system integrity. The uniform method of identifying and symbolizing safety devices is presented in API 14C and adopted in this RP.
Subsea systems within the scope of this document include:

chemical injection lines;
manifolds;
subsea separation;
subsea boosting;
subsea compression;
flowlines;

The safety system includes valves and flow control devices in the production system. The safety system also includes sensors installed in the production system to detect abnormal conditions and allow corrective action to be taken (whether manual or automatic).
The intention is to design subsea safety systems to meet the requirements of IEC ; this document supplements these requirements.
Procedures for testing common safety devices are presented with recommendations for test data, test frequency, and acceptable test tolerances.
Instrumentation logic circuits are not discussed since these should be left to the discretion of the designer as long as the recommended safety functions are accomplished. Rotating machinery is considered in this RP as a unitized process component as it interfaces with the subsea safety system. When rotating machinery (such as a pump or compressor) is installed as a unit consisting of several process components, each component may be analyzed as prescribed in this RP.

This RP is also designated for managers, production technologists, reservoir engineers, facilities engineers, production engineers, well testing engineers, well analysts, operators, and researchers who want to gain a general understanding of dynamic simulation, areas of application, added values, and benefits. The contents compare transient vs steady-state techniques and provide readers with when and how each technique may be effectively applied.
Not included are technical requirements for the hardware of the dynamic simulation system, the specifics of the system calculations, the responses to the output of the dynamic simulation data output, and specifics of what actions are required after the provided data is considered.
An extensive bibliography is provided of documents for additional information on the topics included.
This RP is intended for use by managers, production technologists, reservoir engineers, facilities engineers, production engineers, well testing engineers, well analysts, operators, and researchers who want to gain a general understanding of gas-lift wells and gas-lift operations. It can be used to prepare and present courses on gas-lift wells and operations.
This RP focuses primarily on continuous gas-lift. However, use of intermittent gas-lift, dual gas-lift, and gas-lift for gas wells is mentioned.
Compared to single completions, dual completions have a higher initial cost, have more operating problems, are more difficult and expensive to work over, and often produce less efficiently. Based on experience, most technical gas-lift specialists and operations staff prefer single completions to duals.
It is not the purpose of this document to recommend the practice of dual gas lift. In many cases, dual gas lift is problematic and often it is ineffective. Often it is difficult or even impossible to effectively produce both completions in a dual well using gas lift, over the long term. If there are other feasible alternatives to produce dual wells, they should be considered.
However, many dually completed oil wells should be artificially liftedinitially or after reservoir pressures have declined and/or water cuts have increased. And in many cases, the only practical or feasible method of artificial lift for these wells is gas lift. So, if dual wells must be artificially lifted, and if the only practical or feasible means to do this is with gas lift, every effort should be made to perform this dual gas-lift function as effectively as possible.
Therefore, the purpose of this document is to offer recommended practices, guidelines, and tools to make the best of what may otherwise be a difficult situation. This document also contains suggestions on practices that should be avoided to minimize problems, inefficiencies, and poor economics that may be associated with ineffective dual gas-lift operations.

This recommended practice is based on sound engineering principles, extensive testing and field application experience. In no case is any specific recommendation included which could not be accomplished by presently available techniques and equipment. Consideration is given in all cases to the safety of personnel, compliance with existing regulations, and prevention of pollution.</p:>
This is the First Edition of the "Recommended Practice for Planning, Designing, and Constructing Fixed Offshore Platforms - Load and Resistance Factor Design." This practice has been approved by the API as an alternative to the 20th Edition of the RP2A "Recommended Practice for Planning, Designing, and Constructing Fixed Offshore Platforms."</p:>
The LRFD was first issued in December in draft form. It was consistent in most respects with the 18th Edition of the RP2A. The draft was open to comment for a period of two years. All of the comments received were carefully considered in the development of the First Edition. In general, the provisions are consistent with the 20th Edition of the RP2A.
The actions on the topsides structure and structural components are derived from this document and where necessary, in combination with API, other international standards and the ISO series. The resistances of structural components of the topsides structure are determined by the use of international or national building codes, as specified in this document. If the topsides structure is integrated with the supporting substructure to help resist global platform forces, the requirements of this standard are supplemented with applicable requirements of the associated substructure such as API 2A-LRFD for fixed steel structures and API 2FPS for floating structures. This document is applicable to:
For those parts of floating offshore structures and mobile offshore units that are chosen to be governed by the rules of a recognized classification society, the corresponding class rules supersede the associated requirements of this standard.
This document has limited guidance on corrosion control, alternate structural materials, and other miscellaneous topics that the structural engineer often has to consider.
This document contains requirements for, as well as guidance and information on, the following aspects of topsides structures:

This document defines the seismic requirements for new construction of structures in accordance with API 2A-WSD,22nd Edition and later. Earlier editions of API 2A-WSD are not applicable.
The majority of the ISO -2 document is applicable to the U.S. OCS. Where necessary, this document provides guidance for aligning the ISO -2 requirements and terminology with API. The key differences are as follows.
a) API 2EQ adopts the ISO -2 site seismic zones in lieu of those previously used in API 2A-WSD, 21st Edition and earlier.
b) Only the maps in Figure B.2 are applicable, in lieu of those previously used in API 2A-WSD, 21st Edition and earlier.
c) ISO -2 seismic design approach is also adopted here with:
a two-level seismic design in which the structure is designed to the ultimate limit state (ULS) for strength and stiffness and then checked to the abnormal or accidental limit state (ALS) to ensure that it meets reserve strength and energy dissipation requirements;
the seismic ULS design event is the extreme level earthquake (ELE) [this is consistent with, but not exactly the same as the strength level earthquake (SLE) in API 2A-WSD, 21st Edition and earlier];
the seismic ALS design event is the abnormal level earthquake (ALE) [this is consistent with, but not exactly the same as the ductility level earthquake (DLE) in API 2A-WSD, 21st Edition and earlier].
Only earthquake-induced ground motions are addressed in detail. Other geologically induced hazards such as liquefaction, slope instability, faults, tsunamis, mud volcanoes, and shock waves are mentioned and briefly discussed.
The requirements are intended to reduce risks to persons, the environment, and assets to the lowest levels that are reasonably practicable. This intent is achieved by using:
seismic design procedures which are dependent on the platform's exposure level and the expected intensity of seismic events;
a two-level seismic design check in which the structure is designed to the ultimate limit state (ULS) for strength and stiffness and then checked to abnormal environmental events or the accidental limit state (ALS) to ensure that it meets reserve strength and energy dissipation requirements.
For high seismic areas and/or high exposure level fixed structures, a site-specific seismic hazard assessment is required; for such cases, the procedures and requirements for a site-specific probabilistic seismic hazard analysis (PSHA) are addressed. However, a thorough explanation of PSHA procedures is not included.
Where a simplified design approach is allowed, worldwide offshore maps are included in Annex B that show the intensity of ground shaking corresponding to a return period of years. In such cases, these maps may be used with corresponding scale factors to determine appropriate seismic actions for the design of a structure.

NOTE 1 Floating offshore platforms are often referred to using a variety of abbreviations, e.g. FPS, FSU, FPSO, etc. (see Clauses 3 and 4), in accordance with their intended mission.
NOTE 2 In this standard, the term "floating structure", sometimes shortened to "structure", is used as a generic term to indicate the structural systems of any member of the classes of platforms defined above
NOTE 3 In some cases, floating platforms are designated as "early production platforms". This term relates merely to an asset development strategy. For the purposes of this International Standard, the term "production" includes "early production".
Its requirements do not apply to the structural systems of mobile offshore units (MOUs). These include, among others:
floating structures intended primarily to perform drilling and/or well intervention operations (often referred to as MODUs), even when used for extended well test operations;
floating structures used for offshore construction operations (e.g. crane barges or pipelay barges), for temporary or permanent offshore living quarters (floatels), or for transport of equipment or products (e.g. transportation barges, cargo barges), for which structures reference is made to relevant recognized classification society (RCS) rules.
Its requirements are applicable to all possible life-cycle stages of the structures defined above, such as
design, construction and installation of new structures, including requirements for inspection, integrity management and future removal,
structural integrity management covering inspection and assessment of structures in-service, and
conversion of structures for different use (e.g. a tanker converted to a production platform) or reuse at different locations
The following types of floating structure are explicitly considered within the context of this standard:
a) monohulls (ship-shaped structures and barges);
b) semi-submersibles;
c) spars.
In addition to the structural types listed above, this standard covers other floating platforms intended to perform theabove functions, consisting of partially submerged buoyant hulls made up of any combination of plated and space frame components and used in conjunction with the station keeping systems covered in API 2SK. These other structures can have a great range of variability in geometry and structural forms and, therefore, can be only partly covered by the requirements of this standard. In other cases, specific requirements stated in this standard can be found not to apply to all or part of a structure under design.
In all the above cases, conformity with this standard will require that the design is based upon its underpinning principles and achieves a level of safety equivalent, or superior, to the level implicit in it.
NOTE The speed of evolution of offshore technology often far exceeds the pace at which the industry achieves substantial agreement on innovation in structural concepts, structural shapes or forms, structural components and associated analysis and design practices, which are continuously refined and enhanced. On the other hand, International Standards can only capture explicitindustry consensus, which requires maturation and acceptance of new ideas. Consequently, advanced structural concepts can, in some cases, only be partly covered by the provisions of standard.
This standard is applicable to steel floating structures. The principles documented herein are, however, considered to be generally applicable to structures fabricated in materials other than steel.
Similarly, while this document is directly applicable to oil and gas producing platforms operating at ambient temperature, the principles documented herein are considered to be generally applicable to structures used in conjunction with cryogenic processes, such as floating liquefied gas (FLNG) plants, with the exception of the aspectsrelated to handling and storage of cryogenic liquids.
The structural design and fabrication of the drilling and production modules supported by a floating structure can be carried out in accordance with API 2AWSD, 21st Edition, Errata and Supplement 3.
This recommended practice (RP) provides guidance for floating system integrity management (FSIM) of floating production systems (FPSs), which include tension leg platforms (TLPs), used by the petroleum and natural gas industries to support drilling, production, storage, and/or offloading operations. FPSs described in this RP are governed by local regulatory requirements and recognized classification society (RCS) rules (if classed). No specific regulatory compliance or RCS requirements are restated in this RP. The requirements of this RP do not apply to mobile offshore drilling units (MODUs) or to mobile offshore units (MOUs) used in support of construction operations. For integrity management (IM) considerations, these units are typically governed by RCS rules, and include, among others:
This RP does not address moorings or risers; these are addressed separately by API 2MIM and API 2RIM, respectively. Dynamic positioning is not covered in this RP.
The following types of floating systems are explicitly covered by this RP:
The following types of floating system components are included within the context of this RP:
This RP is directly applicable to oil and gas producing floating systems operating at ambient temperature, including floating liquefied natural gas (FLNG) plants, except for the aspects related to handling and storage of cryogenic liquids.
The FSIM process provided in this RP is applicable to floating systems installed at any location worldwide. However, the referenced metocean criteria has regional limitations.

soil and rock characterization,
design and installation of foundations supported by the seabed (shallow foundations),
identification of hazards,
design of pile foundations, and
soil-structure interaction for risers, flowlines, and auxiliary subsea structures.
Aspects of soil mechanics and foundation engineering that apply equally to offshore and onshore structures are not addressed. The user of this document is expected to be familiar with such aspects
This recommended practice provides guidelines for inspecting mooring components of mobile offshore drilling units (MODUs) and permanent floating installations. Although this document was primarily developed for the moorings of MODUs and permanent floating installations, some of the guidelines may be applicable to moorings of other floating vessels such as pipe-laying barges and construction vessels. Furthermore, some of the guidelines may be applicable to secondary or emergency moorings such as moorings for jack-up units, shuttle tanker moorings, and dynamic positioning (DP) vessel harbor mooring.
The applicability of this document to the moorings of other floating vessels is left to the discretion of the user.
The requirements are divided into two broad types:
1) those that relate to the determination of environmental conditions in general, together with the metocean parameters that are required to adequately describe them;
2) those that relate to the characterization and use of metocean parameters for the design, the construction activities or the operation of offshore structures.
The environmental conditions and metocean parameters discussed comprise
extreme and abnormal values of metocean parameters that recur with given return periods that are considerably longer than the design service life of the structure,
long-term distributions of metocean parameters, in the form of cumulative, conditional, marginal or joint statistics of metocean parameters, and
normal environmental conditions that are expected to occur frequently during the design service life of the structure.
Metocean parameters are applicable tothe determination of actions and action effects for the assessment of existing structures, the site-specific assessment of mobile offshore units, the determination of limiting environmental conditions, weather windows, actions and action effects for pre-service and post-service situations (i.e. fabrication, transportation and installation or decommissioning and removal of a structure), and the operation of the platform, where appropriate.

The requirements are divided into two broad types:
The environmental conditions and metocean parameters discussed are as follows:
Metocean parameters are applicable to:
connected to a permanent floating production system (FPS) used for the drilling, development, production, and/or This recommended practice (RP) provides guidance for the integrity management (IM) of mooring systems storage of hydrocarbons in offshore areas. The scope of this RP extends from the anchor to the connection to the floating unit (e.g. chain stopper) and includes components critical to the mooring system (e.g. turret bearings, fairleads, chain stoppers, anchors, suction piles).
Specific guidance is provided for the inspection, monitoring, evaluation of damage, fitness-for-service assessment, risk reduction, mitigation planning, and the process of decommissioning. This RP incorporates and expands on the IM recommendations found in API 2I and API 2SK. In the event of any discrepancy between API 2MIM and API 2I/API 2SK, API 2I/API 2SK will govern.
This RP is not intended for:
This recommended practice (RP) provides guidance for the integrity management (IM) of risers connected to a permanent floating production system (FPS) used for the drilling, development, production, and storage of hydrocarbons in offshore areas. A riser is typically part of a larger subsea system extending from a wellhead, tree, manifold, template, or other structure on the seabed, to a boarding valve or pig trap on the host platforms topsides. This RP addresses the integrity management of the dynamic portion of the riser system. For the purposes of this RP, a riser has a top boundary that is somewhere at or above the point where it transfers load to the platform structure, and it has a lower boundary where it transfers load into a foundation, which could be a wellhead, pipeline, or subsea structure. For a top-tensioned riser (TTR), the top boundary would typically be the tensioner system hang-off point, and the bottom boundary would be the wellhead. For a steel catenary riser (SCR), the top boundary would typically be the stress joint or flexible joint. Some unusual configurations such as pull-tube SCRs merit special consideration. The top boundaries of a flexible or hybrid riser are typically a flanged connection to the riser end fitting at the top of an I-tube or J-tube, and a bend stiffener at the bottom of a I-tube or J-tube. The IM of the structural support for a riser on the host platform is in the scope of API 2FSIM, although some hybrid configurations, such as pull tubes, can require overlapping riser and structural IM. For risers structurally connected to the platform below the topsides, hull piping can be structurally clamped to the hull up to a boarding valve or pig launcher at the topsides. This is intended to be considered as part of the riser in terms of IM, although it also has structural elements addressed in API 2FSIM.
The scope of this RP includes:
The scope of this RP specifically does not include:
NOTE However, the interface of the riser with these components is important to the IM of the riser system.
Specific recommendations are provided for the inspection, monitoring, evaluation of damage, fitness-for-service assessment, risk reduction, mitigation planning, and decommissioning of risers. This RP incorporates and expands on the integrity management recommendations found in API 2RD, API 17B, and API 17L2.
Specific guidance is provided for the evaluation of structural damage, above- and below-water structural inspection, fitness-for-purpose assessment, risk reduction, mitigation planning, and the process of decommissioning. This recommended practice incorporates and expands on the recommendations of Section 14, "Surveys" and Section 17, "Assessment of Existing Platforms" as previously provided in API 2A-WSD, 21st Edition. See Annex A for additional information and guidelines on the provisions stated in the numbered sections of this document.
The SIM process provided in this recommended practice is applicable to existing platforms installed at any location worldwide. However, the recommended practice provides specific metocean criteria, which are only applicable for use in fitness-for-purpose assessments of platforms located in the U.S. Gulf of Mexico and the U.S. West Coast.
For guidelines, recommended practices, and other requirements relating to planning, designing, and constructing new fixed offshore platforms, including reuse and change-in-use of existing platforms, reference should be made to the latest edition of API 2A-WSD.
For guidelines, recommended practices, and other requirements relating to planning, designing, and constructing new offshore floating production systems, including reuse and change-in-use of existing floating production systems, reference should be made to the latest edition of API 2FPS.
The design procedure specified in this document is based on a deterministic approach where the mooring system responses such as line tensions, vessel offsets, and anchor loads are evaluated for a design environment defined by a return period. The mooring system responses are then checked against the mooring strength, offset limit, and anchor capacity to ensure a factor of safety against mooring breakage or excessive vessel excursion. It should be noted that mooring designs based on this approach may not have the same level of reliability, as discussed in Appendix G.
The technology of mooring floating units is growing rapidly. In those areas where data considered adequate were available, specific and detailed recommendations are given. In other areas general statements are used to indicate that consideration should be given to those particular points. Designers are encouraged to utilize all research advances available to them. As offshore knowledge continues to grow, this document will be revised. It is hoped that the general statements contained herein will gradually be replaced by detailed recommendations.
This document does not address mooring inspection/maintenance requirements and synthetic fiber rope mooring. These issues are addressed in the following API documents:
API RP 2I, Recommended Practice for In-Service Inspection of Mooring Hardware for Floating Drilling Units (Reference 1).
API RP 2SM, Recommended Practice for Design, Manufacturing, and Maintenance of Synthetic Fiber Ropes for Offshore Mooring (Reference 2).
a) monohull-based floating production, storage, and offloading units (FPSOs);
b) monohull-based floating storage units (FSOs, FSUs);
c) monohull or semi-submersible based floating production units (FPUs, FPSs);
d) mobile offshore drilling units (MODUs);
e) spar platforms;
f) catenary anchor leg mooring (CALM) buoys (spread mooring only);
g) mobile offshore units (MOUs, e.g., construction, pipelay, floating accommodation vessels).
1.2 This document covers the following aspects of synthetic fiber ropes:
a) design and analysis considerations of mooring system;
b) design criteria for mooring components;
c) rope design;
d) rope specification and testing;
e) rope manufacture and quality assurance;
f) rope handling and installation;
g) in-service inspection and maintenance.
1.3 Application of this document to other offshore mooring applications is at the discretion of the designer and operator. This document is not intended to cover other marine applications of synthetic fiber ropes such as tanker mooring at piers and harbors, towing hawsers, mooring hawsers at single-point moorings (SPMs), and tension leg platform (TLP) tethers. Additionally, very little test data are available for large synthetic fiber ropes permanently deployed around fairleads and thus this document is limited to fiber ropes which span freely between end terminations.
In addition to the recommendations concerning the format for presentation of log data, this document provides several enhancements to the standard log heading. These changes are designed to provide the user with a more complete set of information in consistent locations on all logs. Due to the increasing use of tool calibration and data processing while logging, recommendations are provided concerning documentation of equipment history and processing software. One should identify tool-specific information in other appropriate recommended publications.
The recommended additions to the content of the support information included with hardcopy presentations of well log data, as described in the following, should also be included with digital recordings of the same well logs. The recommended digital formats to be used are provided in API Recommended Practice 66.
The recommendations contained within API Recommended Practice 31A provide some flexibility regarding the dimensions of the actual print field used in the hardcopy presentation of well log data. This flexibility will accommodate the use of commonly available printers and paper sizes as optional alternatives to the 6.25-inch by 9.25-inch fanfold paper on which log data has been traditionally printed. Example figures conforming to this document and printed at the dimensions required for 8.5-inch by 11-inch paper are provided. The changes made to accommodate this flexibility in paper and printer selection will in no way alter the actual scaling sof the log data. Log data curves will precisely "overlay," regardless of the choice of paper or print field dimensions. Any hardcopy presentation of log data that meets all of the information content and format specifications described in the text of this document shall be considered to be in conformance with it.
certifying the hydraulic-horsepower rating of pumping units used in hydraulic fracturing and cementing services operations. The standard also establishes a recommended format for reporting the performance of such pumping units.
This standard is applicable to any type of high pressure pumping unit, regardless of components such as prime movers, transmissions, and pumps.
A.Fluid block, which may be corrected by:
1. Reduction in water in saturation.
2. Increased deformability (lower interfacial tension) of blocking droplets.
3. Reduction in viscosity or breaking of emulsions.
4. Alteration in gettability to redistribute fluid phases.
B. Particle block (particularly clays), which may be corrected by:
1. Reduction in amount of water associated with the particle.
2. Removal or redistribution of the particles.
b. The methods herein described are tentative, pending further evaluation and improvement. They represent procedures currently used in the laboratories of several major oil and service companies, and range in character from complex laboratory installations to simple qualitative tests capable of application in the oil field. It is conceded that information is generally lacking in the area of well stimulation, particularly as regards subsurface conditions. Accordingly, these tests are not represented as absolute methods for determining well-stimulation procedure. Rather, they are to be considered as an aid in comparing the many products currently available for well stimulation.
1. Prevent or minimize emulsification of treating fluid with formation fluid,
2. Reduce water saturation,
3. Alter gettability,
4. Suspend fine particles dislodged by the treatment for removal or redistribution, and
5. Stabilize foam or emulsion in the treating fluid.
B.The diversity of function has resulted in the availability of a large number of products for use in petroleum production operation. Testing of surface active agents as described herein is primarily for qualitative comparison of performance and for general screening related to preceding Paragraph A, items 1-4. Procedures are given for the following:
1. emulsion and sludge tests,
2. measurement of fluid flow through cores,
3. Measurement of interfacial tension, and
4 measurement of wettability
C. Since chemical activity of a surface active agent (surfactant) depends on its chemical environment, pressure, temperature, and time, the user is advised to test the surface active agent in the presence of all additives to be used in a field treatment at their appropriate concentration. Production batch and shelf life may effect variation in surface active agents properties, so that in many cases even these items must be considered in evaluating a surface active agent.
water, injected water, aqueous work over fluids, and stimulation fluids). Bacterial analyses, bioassay (toxicity tests for marine animals), NORM determination, and membrane filter procedures are outside the scope of this document.
Biological determination of the species and concentration of bacteria are covered in NACE TM-94, Field Monitoring of Bacterial Growth in Oilfield Systems. Determinations of Naturally Occurring Radioactive Materials (NORM) in oilfield waters is discussed in API Bulletin E2, Bulletin on Management of Naturally Occurring Radioactive Materials (NORM) in Oil and Gas Production.
Membrane filter procedures are covered in NACE TM01- 73, Test Methods for Determining Water Quality for Subsurface Injection Using Membrane Filters.
Analyses for residuals of proprietary organic treatment chemicals, such as corrosion inhibitors, demulsifiers, scale inhibitors, water clarifiers, biocides, etc. are also outside the scope of this document. However, analyses for generic components of proprietary chemicals, such as phosphate (scale inhibitor), are included in this document.
Lastly, analyses of nonhazardous oilfield waste (NOW), such as drilling fluid, soil, cores, etc. are outside the scope of this document. However, analyses of separated water (including filtrates) from such sources are within the scope.
The analytical methods presented in this document were selected for their accuracy, reproducibility, and applicability to oilfield systems. For most constituents, several methods of varying degrees of complexity and accuracy are presented to provide the analyst with the opportunity to choose the most appropriate and cost effective method pertinent to his/her needs.
While the cited methods may also be used as indicators of the environmental quality of oilfield waters, regulatory agencies prescribe their own analytical methods that must be followed. These regulatory agencies should be consulted to obtain the relevant analytical procedures for cases in which data is to be used to verify environmental compliance.
This standard does not address safety or operational issues except where environmental, safety, and operational issues are intertwined. Process design and equipment selection are not addressed in detail. This publication does not specifically address requirements of process safety management (refer to 29 CFR Part .119) that must be considered in gas plant design and operations.
oil and gas production operations. It is intended to be applicable to contractors as well as operators. Facilities within the scope of this document include all production facilities, including produced water handling facilities. Offshore and arctic areas are beyond the scope of this document. Operational coverage begins with the design and construction of access roads and well locations, and includes reclamation, abandonment, and restoration operations. Gas compression for transmission purposes or production operations, such as gas lift, pressure maintenance, or enhanced oil recovery (EOR) is included; however, gas processing for liquids recovery is not addressed. Annex A provides guidance for a company to consider as a good neighbor.
This document is intended to address environmental considerations and not safety or operational issues. However, there are items discussed, i.e., formation pressure control, for which there are mutual environmental, safety, and operational considerations. Similarly, this standard does not address obligations that may be required by the landowner and lease agreement.
The purpose of these recommended practices is to provide information that can serve as a guide for installation and testing of blowout prevention equipment systems on land and marine drilling rigs (barge, platform, bottom-supported, and floating). Blowout prevention equipment systems are composed of all systems required to operate the blowout preventers (BOPs) under varying rig and well conditions. These systems are: blowout preventers (BOPs), choke and kill lines, choke manifold, hydraulic control system, marine riser, and auxiliary equipment. The primary functions of these systems are to confine well fluids to the wellbore, provide means to add fluid to the wellbore, and allow controlled volumes to be withdrawn from the wellbore. In addition, diverter systems are addressed in this Recommended Practice, though their primary purpose is to safely divert flow rather than to confine fluids to the wellbore. Refer to API Recommended Practice 64 for additional information on diverter systems. Marine risers are not dealt with in detail in this document. Refer to API Recommended Practice 16Q for additional information on marine drilling risers.
1.2 WELL CONTROL
Procedures and techniques for well control are not included in this publication since they are beyond the scope of equipment systems contained herein (refer to API Recommended Practice 59).
1.3 BOP INSTALLATIONS
In some instances, this publication contains a section pertaining to surface BOP installations followed by a section on subsea BOP installations. A delineation was made between surface and subsea equipment installations so these recommended practices would also have utility in floating drilling operations. Statements concerning surface equipment installations also generally apply to subsea equipment installations.
1.4 EQUIPMENT ARRANGEMENTS
Recommended equipment arrangements, as set forth in this publication, are adequate to meet specified well conditions. It is recognized that other arrangements may be equally effective and can be used in meeting well requirements and promoting safety and efficiency.
1.5 LOW TEMPERATURE OPERATIONS
Although operations are being conducted in areas of extremely low temperatures, a section specifically applicable to this service was not included since current practice generally results in protecting existing BOP equipment from this environment.
1.6 IN-THE-FIELD CONTROL SYSTEM ACCUMULATOR CAPACITY
It is important to distinguish between the standards for in-the-field control system accumulator capacity established here in Recommended Practice 53 and the design standards established in API Specification 16D.
API Specification 16D provides sizing guidelines for designers and manufacturers of control systems. In the factory, it is not possible to exactly simulate the volumetric demands of the control system piping, hoses, fittings, valves, BOPs, etc. On the rig, efficiency losses in the operation of fluid functions result from causes such as friction, hose expansion, control valve interflow as well as heat energy losses. Therefore, the establishment by the manufacturer of the design accumulator capacity provides a safety factor. This safety factor is a margin of additional fluid capacity which is not actually intended to be usable to operate well control functions on the rig.
For this reason, the control system design accumulator capacity formulas established in Specification 16D are different from the demonstrable capacity guidelines provided here in Recommended Practice 53.
The original control system manufacturer shall be consulted in the event that the field calculations or field testing should indicate insufficient capacity or in the event that the volumetric requirements of equipment being controlled are changed, such as by the modification or changeout of the BOP stack.
The purpose of these recommended practices is to provide information that can serve as a guide for installation and testing of blowout prevention equipment systems on land and marine drilling rigs (barge, platform, bottom-supported, and floating). Blowout prevention equipment systems are composed of all systems required to operate the blowout preventers (BOPs) under varying rig and well conditions. These systems are: blowout preventers (BOPs), choke and kill lines, choke manifold, hydraulic control system, marine riser, and auxiliary equipment. The primary functions of these systems are to confine well fluids to the wellbore, provide means to add fluid to the wellbore, and allow controlled volumes to be withdrawn from the wellbore. In addition, diverter systems are addressed in this Recommended Practice, though their primary purpose is to safely divert flow rather than to confine fluids to the wellbore. Refer to API Recommended Practice 64 for additional information on diverter systems. Marine risers are not dealt with in detail in this document. Refer to API Recommended Practice 16Q for additional information on marine drilling risers.
1.2 WELL CONTROL
Procedures and techniques for well control are not included in this publication since they are beyond the scope of equipment systems contained herein (refer to API Recommended Practice 59).
1.3 BOP INSTALLATIONS
In some instances, this publication contains a section pertaining to surface BOP installations followed by a section on subsea BOP installations. A delineation was made between surface and subsea equipment installations so these recommended practices would also have utility in floating drilling operations. Statements concerning surface equipment installations also generally apply to subsea equipment installations.
1.4 EQUIPMENT ARRANGEMENTS
Recommended equipment arrangements, as set forth in this publication, are adequate to meet specified well conditions. It is recognized that other arrangements may be equally effective and can be used in meeting well requirements and promoting safety and efficiency.
1.5 LOW TEMPERATURE OPERATIONS
Although operations are being conducted in areas of extremely low temperatures, a section specifically applicable to this service was not included since current practice generally results in protecting existing BOP equipment from this environment.
1.6 IN-THE-FIELD CONTROL SYSTEM ACCUMULATOR CAPACITY
It is important to distinguish between the standards for in-the-field control system accumulator capacity established here in Recommended Practice 53 and the design standards established in API Specification 16D.
API Specification 16D provides sizing guidelines for designers and manufacturers of control systems. In the factory, it is not possible to exactly simulate the volumetric demands of the control system piping, hoses, fittings, valves, BOPs, etc. On the rig, efficiency losses in the operation of fluid functions result from causes such as friction, hose expansion, control valve interflow as well as heat energy losses. Therefore, the establishment by the manufacturer of the design accumulator capacity provides a safety factor. This safety factor is a margin of additional fluid capacity which is not actually intended to be usable to operate well control functions on the rig.
For this reason, the control system design accumulator capacity formulas established in Specification 16D are different from the demonstrable capacity guidelines provided here in Recommended Practice 53.
The original control system manufacturer shall be consulted in the event that the field calculations or field testing should indicate insufficient capacity or in the event that the volumetric requirements of equipment being controlled are changed, such as by the modification or changeout of the BOP stack.
information that can serve as a voluntary industry guide for safe well control operations. This publication is designed to serve as a direct field aid in well control and as a technical source for teaching well control principles. This publication establishes recommended operations to retain pressure control of the well under pre-kick conditions and recommended practices to be utilized during a kick. It serves as a companion to API RP 53, Recommended Practice for Blowout Prevention Equipment Systems for Drilling Wells and API RP 64 Recommended Practice for Diverter Systems Equipment and Operations (reader should check for the latest edition). RP 53 establishes recommended practices for the installation and testing of equipment for the anticipated well conditions and service and RP 64 establishes recommended practices for installation, testing, and operation of diverters systems and discusses the special circumstances of uncontrolled flow from shallow gas formations.
These test methods are primarily intended for thread compounds formulated with a lubricating base grease and are not applicable to some materials used for lubricating and/or sealing thread connections. It is recognized that many areas can have environmental requirements for products of this type. This International Standard does not include requirements for environmental compliance. It is the responsibility of the end user to investigate these requirements and to select, use and dispose of the thread compounds and related waste materials accordingly.
This International Standard covers the qualification of inspection personnel, a description of inspection methods and apparatus calibration and standardization procedures for various inspection methods. The evaluation of imperfections and marking of inspected OCTG are included.
This International Standard is applicable to field inspection of OCTG and is not applicable for use as a basis for acceptance or rejection (for which the relevant purchasing specification is applicable, see 5.4.2).
This publication was prepared under the auspices of the API Subcommittee of Tubular Goods and the Resource Group on Threading and Gauging. As such, the scope is limited to inspection of API casing, tubing, and line pipe connections. However, the basic techniques of gauge usage apply to any threads for which the thread element specifications are known. Specifically, this recommended practice was written to supplement and augment the latest editions of API Specifications 5CT and 5L, which mandate physical and mechanical properties of casing, tubing, and line pipe. Additionally, this recommended practice is designed to be used with the latest edition of API Specification 5B, Specification for Threading, Gauging, and Thread Inspection of Casing, Tubing, and Line Pipe Threads. It does not duplicate the massive dimensional tables contained in the latest edition of API Spec 5B. Instead, it provides instruction in inspection techniques appropriate to comparing the dimension of the product with specified dimensions and tolerances for that product. Accordingly, the primer can be used for the inspection of API thread elements without direct reference to the latest edition of Spec 5B. In all cases, the latest edition of Spec 5B takes precedence if a dispute arises between parties.
This publication uses photographs to demonstrate the proper use of representative gauges normally used by thread inspectors. Gauges presented are limited to those appropriate to both mill and field use. Thus, nonportable instruments such as comparators and contour readers are not included. However, there is no intent to limit the use of such instruments or methods by inspectors.
1.1The statements on corrosion of casing and tubing as given herein were developed with the cooperation of the Technical Practices Committee on Corrosion of Oil and Gas Well Equipment, NACE International (formerly the National Association of Corrosion Engineers).
1.2It is suggested that the selection of a thread compound for casing and tubing be given careful consideration by the user, bearing in mind that a satisfactory compound should possess certain properties, the major of which are (a) to lubricate the thread surfaces to facilitate joint makeup and breakout without galling, and (b) to seal voids between the mating thread surfaces and effectively prevent leakage. Compounds that have given outstanding service for casing and tubing under both laboratory and field conditions are described in the latest edition of API Bulletin 5A2.
Note: Thread compounds described in the latest edition of API Bulletin 5A2 should not be used on rotary shouldered connections.
1.3Some generalized suggestions on prevention of damage to casing and tubing by corrosive fluids are given in 4.8.16 and 5.5.15. It is not, however, within the scope of this recommended practice to provide detailed suggestions for corrosion control under specific conditions. Many variables may be involved in a specific corrosion problem and interrelated in such a complex fashion as to require detailed attention to the specific problem. For more complete technical information on specific corrosion problems, the user should consult the official publication of NACE International, Corrosion, or contact: Chairman, Technical Practices Committee on Corrosion of Oil and Gas Well Equipment, T-1, NACE Int'l, South Creek Drive, P.O. Box , Houston, Texas - .
It categorizes test severity into four test classes.
It describes a system of identification codes for connections.
This International Standard does not provide the statistical basis for risk analysis.
This International Standard addresses only three of the five distinct types of primary loads to which casing and tubing strings are subjected in wells: fluid pressure (internal and/or external), axial force (tension or compression), bending (buckling and/or wellbore deviation), as well as make-up torsion. It does not address rotation torsion and non-axisymetric (area, line or point contact) loads.
This International Standard specifies tests to be performed to determine the galling tendency, sealing performance and structural integrity of casing and tubing connections. The words casing and tubing apply to the service application and not to the diameter of the pipe.
This recommended practice was created to provide a standard industry practice for the shop or field welding of connectors to pipe.
The technical content provides requirements for welding procedure qualification, welder performance qualification, materials, testing, production welding and inspection. Additionally, suggestions for ordering are included.
1.2 EQUIPMENT
This recommended practice covers the weld fabrication of connectors and handling attachments such as lift eyes and landing pads to pipe.
This document includes practices currently being implemented by a broad spectrum of the industry. This recommended practice is intended to be analogous to API 6A PSL 1 with additional requirements specific to the equipment fabrication.

This standard also includes practices used within industry and is intended to be analogous to API 6A PSL 1 with additional requirements specific to the equipment fabrication.
Expandable systems will include drilling liners, hangers, connections, receivers, and launchers for downhole use as defined herein. Only permanently installed equipment/components are covered by this recommended practice. Slotted liners and tools used for the expansion of the tubular goods (such as, but not limited to, implementation tools, pumps, jacks, and expansion tools) are not addressed by this recommended practice.
The recommendations provided herein apply to the transportation on railcars of API 5L steel line pipe in sizes 2 3/8 and larger in lengths longer than single random. These recommendations cover coated or uncoated pipe, but they do not encompass loading practices designed to protect pipe coating from damage.
1.2 Basic Rules and Requirements
Certain minimum mandatory rules governing the loading practices are prescribed by the Association of American Railroads (AAR) as referenced in the next section.
The recommendations given herein are supplementary to the AAR loading practices. If any recommendations are in conflict with AAR loading practices, those of AAR shall govern.
NOTE If the AAR loading rules are not applicable to the railroad transportation of line pipe in the country of origin, the basic loading practice shall be as prescribed in the applicable nationally recognized loading rules and requirements for the type of railroad cars used in the country of origin and that document becomes the reference to which these supplementary recommendations apply.
These supplementary recommendations to AAR rules are for the convenience of purchasers and manufacturers in the loading and shipping of pipe and are not intended to inhibit purchasers and manufacturers from using other supplementary loading and shipping practices by mutual agreement.

b. Section 2 Coating Material Specification
c. Section 3 Laboratory Coating Testing
d. Section 4 Application Practices
e. Section 5 Production Inspection and Acceptance
The Recommendation is limited to the application of internal coatings on new pipe prior to installation.
It is intended that the applicator be responsible for complying with all of the provisions of this Recommended Practice, but that the Purchaser may make any investigation necessary to satisfy himself of compliance by the applicator.
This document contains practices recommended for use in the inspection of new line pipe subsequent to production by the manufacturer. Appendix A contains ordering information for owners desiring to order inspection of new pipe per this document. The basis for performing an inspection may have its origin either in API Specification 5L or in a supplemental specification or contract prepared by the owner. The inspections represented by the practices may be placed in one of three categories as follows:
a. Inspections specified in API Specification 5L.
b. Inspections specified as one of several options in API Specification 5L.
c. Inspections not specified in API Specification 5L.
This recommended practice provides external fusion bonded epoxy coating of line pipe for use in transportation pipelines. The Recommended Practice is limited to the application of external coatings on pipe prior to installation. There may exist differences in the surface condition of pipes produced by the various pipe making processes permitted under the latest editions of API standards. Surface conditions may preclude the coating of such pipe.
The applicator shall be responsible for assuring compliance with all of the provisions of this practice however, the Purchaser may make any investigation necessary to satisfy himself of compliance by the applicator.
These recommendations cover coated or uncoated pipe, but they do not encompass loading practices designed to protect pipe coating from damage. These recommendations are not applicable to pipe-laying vessels or supply vessels. They must be considered as supplementary to the existing rules of governing agencies.
These recommendations are supplemental to shipping rules for the convenience of purchasers and manufacturers in the specification of loading and shipping practices and are not intended to inhibit purchasers and manufacturers from using other supplemental loading and shipping practices by mutual agreement.
The purpose of this Recommended Practice (RP) is to provide guidelines for the surveillance and/or inspection of API products at supplier locations. This Recommended Practice establishes a set of general guidelines addressing the protocol between purchasers, suppliers and the purchaser representative for surveillance and/or inspection by the purchaser representative. This Recommended Practice is a general document for use at the request of the purchaser of API products. This document is intended to provide only general guidance to the industry. The issue of the roles and responsibilities of the parties is a subject that should be addressed as part of negotiations between the purchaser and the supplier.
Included as a part of this document are product specific appendices. Processes other than those included will be considered for inclusion in this Recommended Practice. Persons desiring to have other processes considered shall submit a request to the "Committee on Standardization of Tubular Goods."
This Recommended Practice addresses the relationship and responsibility of the purchaser, suppliers, and purchaser representatives regarding surveillance and/or inspection of products from placement of the order or the pre-production meeting, as appropriate, through the point of title transfer from suppliers to purchasers. The use of the document by the parties is voluntary and it is merely intended to provide general guidelines on issues that should be addressed by the parties. This may include activities such as laboratory testing, nondestructive testing, dimensional verification, coating, shipping, handling/storage or other related activities.
This RP is not intended to conflict with those inspection activities outlined in other API documents. In case of a conflict, the other applicable API Document shall prevail.
1.2
Prove-up inspection is a method to evaluate the radial depth of imperfections detected by automated inspection equipment or other nondestructive testing (NDT) technique(s) to determine acceptance criteria compliance with the appropriate API specification.
1.3The recommended prove-up practices established within this document are intended as a guide, and nothing in this guide should be interpreted to prohibit the agency or owner from supplementing the guide with other techniques or extending existing techniques.
1.4

In wells drilled in deep ocean waters, water flows from shallow formations can compromise the hydraulic integrity of the tophole section. Modes of failure include: (1) poor isolation by cement resulting in casing buckling/shear; (2) pressure communication to other shallow formations causing them to be overpressured; and (3) disturbance of the seafloor due to breakthrough of the shallow flow to the mudline. Such damage can and has resulted in the complete loss of drilling templates containing previously cased wells. Additionally, such shallow flow can result in changes in the state of stress in the tophole section, possibly resulting to damage to existing casings in the present or adjacent wells later in the life of the well.
Flows from these shallow formations are frequently a result of abnormally high pore pressure resulting from under-compacted and over-pressured sands caused by rapid deposition. Not all flows are the result of these naturally developed formation geo-pressures. Hydraulic communication with deeper, higher pressure formations is another cause for abnormal shallow pressures. Some of the observed shallow flow problems have been due to destabilization of gas hydrates or induced storage during drilling and casing and cementing operations. Although minor compared to geo-pressured sands, flows due to induced storage may still cause damage from sediment erosion or mining, breakthrough to adjacent wells and damage to the cement before it sets. These problems can worsen with each additional well when batch setting shallow casings. Although most of the discussion in this text is focused on shallow water flow (SWF), shallow flows can be mixtures of water, gas and formation fines. In most cases the concepts are similar and can be employed with minor modifications, depending on the type of flow.
Flows allow production of sand and sediments resulting in hole enlargement which can increase the flow potential and make it more difficult to control. The enlargement may also cause caving of formations above the flow interval. The flow of water and formation material from these zones can result in damage to the wells including foundation failure, formation compaction, damaged casing (wear and buckling), reentry and control problems and sea floor craters, mounds and crevasses (OTC , IADC/SPE ).
used by many operators drilling wells in deep water. In a number of cases, there is not a single way of performing a specific operation. In some cases, several options may be listed, but in others there may be practices which are successful, but which are not listed in this document. This document is not meant to limit innovation.

The content of this document is not all inclusive, and guidance from other sources may apply. Note that this standard is not meant to be a stand-alone training manual or well design standard. Although fairly comprehensive, there are still many details that are not discussed and that should be addressed when drilling and cementing wells in deepwater. It is meant to highlight key parameters for increasing the chance of successfully drilling and cementing casings where there is a risk of shallow-water flow and to discuss options that are available. More details can be gleaned from the references listed in the bibliography. Most of the information in this document is from U.S. Gulf of Mexico experience. The concepts can be applied in other deepwater environments with appropriate modifications. The user should consult experts within the industry for specific details of the cementing process relating to the technology being used by a specific company for a specific scenario. The construction of the casings through the SWF zones should be a team effort to be successful. All parties involved shall participate in the planning and execution of all phases of the process to ensure successful construction of the conductor and surface casings.
In this standard, where practical, U.S. customary units (USC) are included in parentheses for information. The units do not necessarily represent a direct conversion of metric units (SI) to USC units, or USC to SI. Consideration has been given to the precision of the instrument making the measurement. For example, thermometers are typically marked in one-degree increments; thus, temperature values have been rounded to the nearest degree.

The definition of gas gathering reflects the varied nature of the gas industry throughout the country. Because of the regional and operational diversity within the gas industry, additional guidanceeither within the regulation or through incorporation of a recognized industry standardis necessary to ensure appropriate and consistent application of the gas gathering line definition. This Recommended Practice was developed as such a standard through the joint efforts of the regulated community.
The group that developed this Recommended Practice (RP) was called the Well Rate Determination Subgroup, with the charter to make recommendations regarding measurement of flow rates from individual wells. However, as their work unfolded, the charge was slightly broadened to cover the more general subject of multiphase flow measurement, whether that flow was from a single well or the combined flow of two or more wells.
1.1 USE WITH OTHER RECOMMENDED PRACTICES
It is intended that this RP be used in conjunction with other similar documents to guide the user toward good measurement practice in upstream hydrocarbon production applications. The term upstream refers to those measurement points prior to, but not including, the custody transfer point.
Specifically this document will address in depth the question of how the user measures (multiphase) flow rates of oil, gas, water, and any other fluids that are present in the effluent stream of a single well. This requires the definition not only of the methodology which is to be employed, but also the provision of evidence that this methodology will produce a quality measurement in the intended environment. Most often, this evidence will take the form of a statement of the uncertainty of the measurement, emphasizing how the uncertainty statement was derived.
This RP will prove especially important when used in conjunction with other similar documents, such as those that address how commingled fluids should be allocated to individual producers. For example API RP 85 Use of Subsea Wet-Gas Flowmeters in Allocation Measurement Systems [Ref. 2] describes a methodology for allocation based on relative uncertainty, the identification of which is discussed in detail in section 8.
This Recommended Practice covers monitoring, diagnostic testing, the establishment of a maximum allowable wellhead operating pressure (MAWOP) and documentation of annular casing pressure for the various types of wells that occur offshore. Included also is a discussion of risk assessment methodologies that can be used for the evaluation of individual well situations where the annular casing pressure is not within the MAWOP guidelines.
This Recommended Practice recognizes that annular casing pressure results in various levels of risk to the safety of personnel, property and the environment. The level of risk presented by annular casing pressure depends on many factors, including the design of the well and the source of the annular casing pressure. This Recommended Practice provides guidelines in which a broad range of casing annuli that exhibit annular pressure can be managed in a routine fashion while maintaining an acceptable level of risk. Annular pressures that do not conform to the guidelines in this Recommended Practice may still have an acceptable level of risk, but they need to be evaluated on a case-by-case basis.
This Recommended Practices establishes an acceptable level of risk for annular casing pressure using three parameters. First, annuli that exhibit annular casing pressure of 100 psig or less present little risk and should be monitored. Second, annular casing pressure that is greater than 100 psig and that has been diagnosed as sustained casing pressure (SCP) must bleed to zero psig. Third, a Maximum Allowable Wellhead Operating Pressure (MAWOP) is established for each non-structural casing annulus that exhibits annular casing pressure, including thermal casing pressure, sustained casing pressure or operator-imposed pressure. If the annular casing pressure does not meet the criteria established in this Recommended Practice, this does not mean that the risk presented by the annular pressure is unacceptable. Rather, it indicates that the annular casing pressure needs to be managed on a case-by-case basis that goes beyond the scope of this Recommended Practice. The case-by-case management of annular casing pressure may include the use of risk assessment techniques. Techniques that may be used for case-by-case risk assessment are discussed in Section 10 of this Recommended Practice. In some cases, the annular casing pressure may need to be reduced or eliminated by well work. In other cases, the risk may be mitigated by other methods. Procedures for eliminating annular casing pressure or mitigating the risk are beyond the scope of this Recommended Practice.

This document is intended to serve as a guide to monitor and manage annular casing pressure (ACP) in onshore wells, including production, injection, observation/monitoring, and storage wells. This document applies to wells that exhibit thermally induced, operator-imposed, or sustained ACP. It includes criteria for establishing diagnostic thresholds (DTs), monitoring, diagnostic testing, and documentation of ACP for onshore wells. Also included is a discussion of risk management considerations that can be used for the evaluation of individual well situations where the annular casing pressure falls outside the established diagnostic thresholds.
This document recognizes that an ACP outside of the established DTs can result in a risk to well integrity. The level of risk presented by ACP depends on many factors, including the design of the well, the performance of barrier systems within the well, the source of the annular casing pressure, and whether there is an indication of annular flow exists. This document provides guidelines in which a broad range of casing annuli that exhibit annular casing pressure can be managed while maintaining well integrity.
1.2 Conditions of Applicability
This document applies to annular casing pressure management in onshore wells during normal operation. In this context, normal operation is considered the operational phase during the life of a well that begins at the end of the well construction process and extends through the initiation of well abandonment operations, excluding any periods of well intervention or workover activities.
The design and construction of wellbores for the prevention of unintended ACP and the management of ACP during drilling, completion, well intervention and workover, and abandonment operations are beyond the scope of this document. The isolation of potential flow zones during well construction (zones that can be the source of sustained annular casing pressure) is addressed in API 65-2. In some cases, the annular casing pressure can be reduced or remediated. The remediation of sustained casing pressure (SCP) is also beyond the scope of this document.
This document considers situations where the total drilling operation is performed balanced or overbalanced, including both hydrostatically overbalanced (no supplemental surface pressure needed to control inflow) and hydrostatically underbalanced (supplemental surface pressure needed to control inflow) systems. For underbalanced operations, refer to API 92U.
This document does not cover MPD operations with subsea BOP stacks.
Although this document only addresses PMCD, most of the equipment described may also be used for the surface back-pressure (SBP) method of managed pressure drilling. However, much of the equipment used for SBP is not required for PMCD, and will not be covered here.
The following methods, described briefly, are also used during lost circulation conditions; however, they are outside the scope of this document:
a)blind drilling (see 4.3.2);
b)continuous annular injection drilling (see 4.3.3);
c)floating mud cap drilling (see 4.3.4).
This document provides information for planning, installation, testing, and operation of wells drilled with surface back-pressure (SBP) managed pressure drilling (MPD). This document applies only to drilling rigs with subsea blowout preventers (BOPs).
This document addresses situations where the total drilling operation is performed balanced or overbalanced, including both hydrostatically overbalanced (no supplemental surface pressure needed to control inflow) and hydrostatically underbalanced (supplemental surface pressure needed to control inflow) systems. For underbalanced operations refer to API 92U.
1.2 Installation and Use of Blowout Preventers
Installation, testing, and use of BOPs and associated secondary well control equipment are similar to conventional drilling operations and are not included in this publication. This equipment should only be used during routine MPD operations (e.g. seal element changeout) if an adequate risk assessment has been performed. Refer to API 53 for information regarding installation and testing of BOPs in a conventional drilling operation.
The UBD system is composed of all equipment required to safely allow drilling ahead in geological formations with pressure at surface and under varying rig and well conditions. These systems include: the rig circulating equipment, the drill string, drill string non return valves (NRV), surface BOP, control devices (rotating or non-rotating) independent of the BOP, choke and kill lines, UBD flowlines, choke manifolds, hydraulic control systems, UBD separators, flare lines, flare stacks and flare pits and other auxiliary equipment. The primary functions of these systems are to contain well fluids and pressures within a design envelope in a closed flow control system, provide means to add fluid to the wellbore, and allow controlled volumes to be withdrawn from the wellbore.
1.1.1 Managed pressure drilling (Category A) and mud cap drilling (Category C) techniques as defined in the IADC Well Classification System for Underbalanced Operations and Managed Pressure Drilling are not included in this publication. The phrase managed pressure drilling or the acronym MPD is only used in this document in the context of the IADC Well Classification System.

of well design criteria and associated equipment. This recommended practice (RP) provides engineers a reference for DW well design as well as drilling and completion operations. This RP will also be useful to support internal reviews, internal approvals, contractor engagements, and regulatory approvals.
The scope of this RP is to discuss DW drilling and completion activities performed on wells that are constructed using subsea blowout preventers (BOPs) with a subsea wellhead. This document addresses the following.
Identifies the appropriate barrier and load case considerations to maintain well control during DW well operations (drilling, suspension, completion, production, and abandonment).
Supplements barrier documentation in API 65-2 with a more detailed description of barriers and discussion of the philosophy, number, type, testing, and management required to maintain well control. This document also supplements the barrier documentation in API 90 in regard to annular pressure buildup (APB). Abandonment barrier requirements are described for use when designing the well.
Discusses load assumptions, resistance assumptions, and methodologies commonly used to achieve well designs with high reliability. The load case discussion includes less obvious events that can arise when unexpected circumstances are combined.
Describes the risk assessment and mitigation practices commonly implemented during DW casing and equipment installation operations.
The purpose of this document is to enhance safety and minimize the likelihood of loss of well control or damage to the environment. These practices are generally intended to apply to subsea wells drilled with subsea BOPs in any water depth. Some of the descriptions of rig hardware and operations, such as remotely operated vehicles (ROVs), are less relevant in shallower water depths [e.g. less than 500 ft (152 m)]. In these shallower water depths the operator may substitute alternative hardware or operations that maintain safety and system reliability.
The following aspects of DW well design and construction are outside the scope of this document.
Detailed casing design load case definitions (does not include specific casing designs or design factors). Individual companies combine differing severities of loads and resistances or differing calculation methods to achieve designs with similar high levels of reliability.
Wells drilled and/or completed with a surface BOP and high pressure riser from a floating production system; however, considerations for wells predrilled with floating rigs to be completed to a floating production system are included.
Well control procedures (refer to API 59 for well control information).
Managed pressure drilling operations (including dual gradient drilling).
Production operations and fluids handling downstream of the tree (subsea facilities/subsea architecture, and surface facilities/offloading hydrocarbons).
Intervention operations.
Quality assurance (QA) programs.
This RP is intended for any company, organization, or agency that oversees or responds to oil spills. It is not a comprehensive how-to guide to selecting PPE for every type of situation that may be encountered; rather, it is a guidance document that discusses how proper PPE selection may be a useful control measure for responders when engineering and administrative controls may not be feasible or effective in reducing exposure to acceptable levels.
This recommended practice (RP) provides guidance for the upstream oil and gas industry on hazard identification and risk assessment exercises to assess and mitigate the risk of human injury caused by exposure to a flash fire.
The scope of this document is limited to personnel exposed to the risk of hydrocarbon based flash fires in the upstream Exploration and Production sector of the oil and gas industry. In general, this group includes oil and gas production, drilling, well bore (well servicing) operations, and gas processing prior to interstate pipeline transportation.
1.2 Conditions of Applicability
This RP focuses on flash fires that result from the unexpected ignition of hydrocarbon vapors. Emergency preparedness (e.g. firefighting, hazmat response) for exposure to fire event greater than a flash fire is excluded from this RP and is addressed by NFPA and other standards organizations.
Arc flash, as discussed in NFPA 70E and its other related standards, are outside the scope of this document.
Maintenance, care, and limitation of various fire resistant clothing (FRC) materials are outside the scope of this document. These items are addressed by the manufacturer and clothing-related standards.
Typical practices in the application of wire rope to oil field service are indicated in Table 1, which shows the sizes and constructions commonly used. Because of the variety of equipment designs, the selection of constructions other than those shown is justifiable.
In oilfield service, wire rope is often referred to as wire line or cable. For the purpose of clarity, these various expressions are incorporated in this recommended practice.
The value of work experience is recognized by dividing the guidelines into instructional and testing phases. Any candidate who has the experience prerequisites may complete only the testing phase. If a candidate demonstrates proficiency in all classes of safety devices, a certificate is issued identical to those issued to candidates who first take the instructional phase and then pass the testing phase.
This Recommended Practice (RP) complements API RP 14B, API RP 14C and API RP 14H as well as other API Specifications.
The employer should maintain a record of the training which each employee receives in accordance with this RP. Each employee should be furnished documentation of the successful completion of each level of training.
The training may be either hands-on or classroom based. Some suggested approaches are included. The Recommended Practice encourages the employer, when deciding the conditions under which training and drills are to be carried out, to fully consider all safety aspects of the training. Training should be as broad as is practical. It should emphasize those devices likely to be available to the employee at his or her assigned location.
These guidelines are general and may or may not be sufficient for all circumstances or operations. The employer should not limit or reduce the company's present program as a result of the publication of these guidelines.
NOTE This recommended practice is focused on the components of an effective training system, which can be used to manage any type of training. Annex A lists the fundamental safety training and frequencies recommended to work offshore. The need for additional specific safety or technical training is outside the scope of this document.

This specification covers minimum requirements for material, design, fabrication, and testing of vertical and horizontal emulsion treaters. The jurisdiction of this specification terminates with each pressure vessel as applicable: the emulsion treater with firetube(s) and, if used, the heat exchanger(s) and water siphon. Pressure vessels covered by this specification are classified as natural resource vessels by API 510, Pressure Vessel Inspection Code. An emulsion treater is a pressure vessel used in the oil producing industry for separating oil-water emulsions and gas, and for breaking or resolving emulsified well streams into water and saleable clean oil components. Emulsion treaters are usually equipped with one or more removable firetubes or heat exchange elements through which heat is applied to the water and/or emulsion to aid the emulsion breaking process.
1.2 Background
Emulsion treating is normally conducted on crude oil immediately after it is separated from its associated gas in a vessel referred to as a treater or sometimes as a heater treater. High gas-oil ratio wells or those produced by gas lift may require the installation of an oil and gas separator upstream of the treater to remove most of the associated gas before the emulsion enters the treater. Where the water to oil ratio is high, Freewater knockouts may be required upstream of the treater. The function of the treater is to dehydrate (or dewater) the produced crude oil to a specified level of basic sediment and water (BS&W). Oil-water separation may be enhanced by heating, emulsion breaking chemicals, coalescing media, and/or electrostatic fields in vessels sized for substantial liquid residence time. Process considerations are covered in Annex A. Refer to Figure 1, Figure 2 and Figure 3, which show general arrangements of components, piping and instrumentation. (Some of the illustrated features are considered optional.)

a. Control systems for surface mounted BOP stacks. These systems are typically simple return-to-reservoir hydraulic control systems consisting of a reservoir for storing hydraulic fluid, pump equipment for pressurizing the hydraulic fluid, accumulator banks for storing power fluid and manifolding, piping and control valves for transmission of control fluid to the BOP stack functions.
b. Control systems for subsea BOP stacks (common elements). Remote control of a seafloor BOP stack requires specialized equipment. Some of the control system elements are common to virtually all subsea control systems, regardless of the means used for function signal transmission.
c. Discrete hydraulic control systems for subsea BOP stacks. In addition to the equipment required for surface-mounted BOP stacks, discrete hydraulic subsea control systems use umbilical hose bundles for transmission of hydraulic pilot signals subsea. Also used are dual subsea control pods mounted on the LMRP (lower marine riser package), and housing pilot operated control valves for directing power fluid to the BOP stack functions. Spent water-based hydraulic fluid is usually vented subsea. Hose reels are used for storage and deployment of the umbilical hose bundles. The use of dual subsea pods and umbilicals affords backup security.
d. Electro-hydraulic/multiplex control systems for subsea BOP stacks. For deepwater operations, transmission subsea of electric/optical (rather than hydraulic) signals affords short response times. Electro-hydraulic systems employ multi-conductor cables, having a pair of wires dedicated to each function to operate subsea solenoid valves which send hydraulic pilot signals to the control valves that operate the BOP stack functions. Multiplex control systems employ serialized communications with multiple commands being transmitted over individual conductor wires or fibers. Electronic/optical data processing and transmission are used to provide the security of codifying and confirming functional command signals so that a stray signal, cross talk or a short circuit should not execute a function.
e. Control systems for diverter equipment. Direct hydraulic controls are commonly used for operation of the surface mounted diverter unit. Associated valves may be hydraulically or pneumatically operated.
f. Auxiliary equipment control systems and interfaces. For floating drilling operations, various auxiliary functions such as the telescopic joint packer, 30 in. latch/pin connection, riser annulus gas control equipment, etc., require operation by the control system. These auxiliary equipment controls, though not specifically described herein, shall be subject to the relevant specifications provided herein and requirements for similar equipment.
g. Emergency disconnect sequenced systems (EDS). (Optional) An EDS provides automatic LMRP disconnect when specific emergency conditions occur on a floating drilling vessel. These controls, though not specifically described herein,shall be subject to the relevant specifications provided herein and requirements for similar equipment.
h. Backup Systems (Optional). When the subsea control system is inaccessible or non-functional, an independent control system may be used to operate selected well control, disconnect, and/or recovery functions. They include acoustic control systems, ROV (Remotely Operated Vehicle) operated control systems and LMRP recovery systems. For surface control systems, a reserve supply of pressurized nitrogen gas can serve as a backup means to operate functions in the event that the pump system power supply is lost. These controls, though not specifically described herein, shall be subject to the relevant specifications provided herein and requirements for similar equipment.
i. Special deepwater/harsh environment features (Optional). For deepwater/harsh environment operations, particularly where multiplex BOP controls and dynamic positioning of the vessel are used, special control system features may be employed. These controls, though not specifically described herein, shall be subject to the relevant specifications provided herein and requirements for similar equipment.

Record RetentionThe manufacturer shall maintain all inspection and testing of records for 20 years. These records shall be employed in a quality audit program of assesing or eliminating design, manufacturing, or inspection functions which may have been contributed to the malfunction or failure.
and testing of offshore pedestal mounted cranes. Offshore cranes are defined herein as pedestal mounted elevating and rotating lift devices of the types illustrated in Figure 1 for transfer of materials or personnel to or from marine vessels and structures. Offshore cranes are typically mounted on a fixed (bottom supported) or floating platform structure used in drilling and production operations. API Spec 2C is not intended to be used for the design, fabrication, and testing of davits and/or emergency escape devices. API Spec 2C is also not intended to be used for shipboard cranes or heavy lift cranes. Shipboard cranes are mounted on surface type vessels and are used to move cargo, containers, and other materials while the crane is within a harbor or sheltered area. Heavy lift cranes are mounted on barges or other vessels and are used in construction and salvage operations within a harbor or sheltered area or in very mild offshore environmental conditions.
1.2 Safe Working Limits The intent of this specification is to establish safe working limits for the crane in anticipated operations and conditions. This is accomplished by establishing Safe Working Loads (SWLs) based on allowable unit stresses and design factors. Operation of the crane outside of the limits established by the manufacturer in accordance with the guidelines set forth in this document can result in catastrophic failure up to and including separating the entire crane and operator from the foundation. Compliance with the allowable stresses and design factors set forth in this specification does not guarantee that the crane will not be dismounted from its foundation in the event of a gross overload such as might occur in the event of snagging the supply boat.
1.3 Critical Components A critical component is any component of the crane assembly devoid of redundancy and/or auxiliary restraining devices whose failure would result in an uncontrolled descent of the load or uncontrolled rotation of the upper-structure. Due to their criticality, these components are required to have stringent design, material, traceability, and inspection requirements. The manufacturer shall prepare a list of all critical components for each crane. Appendix A contains an example list of critical components.
1.4 Commentary Further information and references on various topics contained in this specification are included in the Commentary found in Appendix B. The section numbers in Appendix B correspond to the section numbers of this specification. For example, Section 4.3 of this specification, entitled In-service Loads, corresponds to Section B.4.3 in Appendix B.
1.5 RECORD RETENTION The manufacturer shall maintain all inspection and testing records for 20 years. These records shall be employed in a quality audit program of assessing malfunctions and failures for the purpose of correcting or eliminating design, manufacturing, or inspection functions, which may have contributed to the malfunction or failure.
1.6 Manufacturer Supplied Documentation The manufacturer shall supply to the purchaser certain documentation for each crane manufactured. Unless otherwise agreed to by the purchaser, the documentation shall include:
1. Load and information charts oer section 4.2.
2. Crane foundation design forces and moments per section 5.2
3. List of all critical components per Section 1.3 and certification that these components meet the API Spec 2C material, traceability, welding (as applicable), and nondestructive examination requirements.
Operations, Parts, and Maintenance Manual.
5. If requested by the purchaser, failure mode assessments for gross un-intended overloads as per Section 4.6.
Typical applications can include:
a) offshore oil exploration and production applications; these cranes are typically mounted on a fixed (bottomsupported) structure, floating platform structure, or ship-hulled vessel used in drilling and production operations;
b) shipboard applications; these cranes are mounted on surface-type vessels and are used to move cargo, containers, and other materials while the crane is within a harbor or sheltered area; and
c) heavy-lift applications; cranes for heavy-lift applications are mounted on barges, self-elevating vessels or other vessels, and are used in construction and salvage operations within a harbor or sheltered area or in limited (mild) environmental conditions.
Figure 1 illustrates some (but not all) of the types of cranes covered under this specification. While there are many configurations of pedestal-mounted cranes covered in the scope of this specification, it is not intended to be used for the design, fabrication, and testing of davits or emergency escape devices. Additionally, this specification does not cover the use of cranes for subsea lifting and lowering operations or constant-tension systems.
1.2 The primary use of this steel is in tubular joints where portions of the plates will be subject to tension in the thickness direction. Supplementary Requirement S-4 provides for thru-thickness testing of plates by the manufacturer and specifies limits for rejection. The presence of laminators and large non metallic inclusion in these portions of the plates can be extremely damaging. Supplementary Requirement S-1 provides for ultrasonic inspection of those plates by the manufacturer and specifies limits for rejection. If supplementary Requirement S-1 is not used, it is recommended that the plates be subjected to ultrasonic inspection in the fabrication yard prior to being formed into tubular members. Areas of lamination can be determined and marked to permit the placing of these areas where there will not be subject to thru-thickness loading.
1.3 The notch toughness requirements specified in Section 6 are suitable for application below water or above water in areas of temperature climate (14°F minimum service temperature). Cold formed tubulars have less toughness due to straining than that of the original flat plates in section 6 take typical losses in toughens due to straining and aging into consideration. For areas with lower test temperatures shall be used, or fabrication process shall be modified to limit degradation. Supplementary Requirement S-2 provides for impact test at temperatures other than specified in Sect. 6
1.4 Policy American Petroleum Institute (API) specifications are published as an aid to procurement of standardized equipment and materials . These specification other than API, and nothing in any API specification is intended to in to in any way inhibit the purchase of products from companies not authorized to use the API monogram.

This material is intended for fabrication primarily by cold forming and welding as per API Spec 2B. Welding procedure is of fundamental importance and it is presumed that procedures will be suitable for the steel and the intended service. Conversely, the steel should be amenable to fabrication and welding under shipyard and offshore conditions.1.2 The primary use of this steel is in tubular joints where portions of the plates will be subject to tension in the thickness direction. Supplementary Requirement S-4 provides for thru-thickness testing of plates by the manufacturer and specifies limits for rejection. The presence of laminators and large non metallic inclusion in these portions of the plates can be extremely damaging.

1.3 For applications where through-thickness properties are important but not of sufficient concern to justify the expense of Z direction testing, supplementary requirement S-5 provides a low sulfur chemistry intended to reduce the size and number of sulfide inclusions in the plate. Supplement s-5 is neither a substitute for S-4 Through Thickness Testing nor a guarantee of a minimum level of through-thickness ductility.Experience indicates, however, that low-sulfur carbon manganese steels, when tested, usually exhibit percent reduction-of-area of atlas 20. Accordingly , supplementary requirement S-4 when testing is not desired. If tested, low sulfur steel is desired, then both supplementary requirement S-4 and S-5 should be ordered

http://compass.astm.org/DIGITAL_LIBRARY/3PC.PREVIEW/9d8ad981--4d04-b3d7-f1b.htm 01-Apr-86 API SPEC 2H 5TH ED () Specification for Carbon Manganese Steel Plate for Offshore Platform Tubular Joints; Fifth Edition 1.1 Coverage This specification covers two grades of intermediate strength steel plates up to 4 in. thick for use in welded tubular construction of offshore platforms, in selected critical portions which must resist impact, plastic fatigue loading, and lamellar tearing. This material is intended for fabrication primarily by cold forming and welding as per API Spec 2B. Welding procedure is of fundamental importance and it is presumed that procedures will be suitable for the steel and the intended service. Conversely, the steel should be amenable to fabrication and welding under shipyard and offshore conditions. API Specification 2W and 2Y cover companion steels providing similar mechanical properties but with improved weldability. This improvement results from a reduction in the maximum allowed chemical composition and is made possible by changes in the method of heat and/ or processing.1.2 The primary use of this steel is in tubular joints where portions of the plates will be subject to tension in the thickness direction. Supplementary Requirement S-4 provides for thru-thickness testing of plates by the manufacturer and specifies limits for rejection. The presence of laminators and large non metallic inclusion in these portions of the plates can be extremely damaging. Supplementary Requirement S-1 provides for ultrasonic inspection of those plates by the manufacturer and specifies limits for acceptation. If if the purchaser chooses not to specify Supplementary Requirement S-1 it is recommended that a fabrication yard ultrasonic examination be preformed, prior to fit up, to permit relocation of undesirable laminar imperfections to areas free from through-thickness loadings.
1.3 For applications where through-thickness properties are important but not of sufficient concern to justify the expense of Z direction testing, supplementary requirement S-5 provides a low sulfur chemistry intended to reduce the size and number of sulfide inclusions in the plate. Supplement s-5 is neither a substitute for S-4 Through Thickness Testing nor a guarantee of a minimum level of through-thickness ductility.Experience indicates, however, that low-sulfur carbon manganese steels, when tested, usually exhibit percent reduction-of-area of at least 20% reduction of area. Accordingly , supplementary requirement S-5 when testing is not desired. If tested, low sulfur steel is desired, then both supplementary requirement S-4 and S-5 should be ordered.
1.4 The notch toughness requirements specified in Section 6 are suitable for application below water or above water in areas of temperature climate (14°F minimum service temperature). Cold formed materials have less toughness due to straining and aging however, differenced in composition or fabrication practices may result in significantly greater degradation than that just included. Supplementary Requirements S-7 and/ or S-8 deal with strain-aging problem, and consideration should be given to invoking S-7 and/ or S-8 when the strain exceeds 5% or when (Nitrogen x % stain) exceeds 0.040. Supplementary Requirement S-8 provides for testing at the specific temperatures and strain levels of interest and is recommended for all martial purchases which exceed the purchasers experience base.
1.4.1For applications with lower service temperatures, lower test temperatures should be considered Supplementary Requirement S-2 provides for impact tests at temperatures other than those specified in Section 6. S2.1 provides for NDTT or Charpy V-notch testing at -60°c. S2.2 provides for such testing at temperatures less than -40° C but other than -60°C.
1.5 The use of the API monogram is a warranty by the manufacturer to the purchaser that the manufacturer has obtained a license to use the monogram and, further, that the product which bears the monogram conforms to the applicable API specification. However, the American Petroleum Institute does not represent, warrant or guarantee that products bearing the API monogram do in fact conform to the applicable API standard or specification.

1.4.1 For applications with lower service temperatures, lower test temperatures should be considered Supplementary Requirement S-2 provides for impact tests at temperatures other than those specified in Section 6. S2.1 provides for NDTT or Charpy V-notch testing at -60°c. S2.2 provides for such testing at temperatures less than -40° C but other than -60°C.
1.5 The use of the API monogram is a warranty by the manufacturer to the purchaser that the manufacturer has obtained a license to use the monogram and, further, that the product which bears the monogram conforms to the applicable API specification. However, the American Petroleum Institute does not represent, warrant or guarantee that products bearing the API monogram do in fact conform to the applicable API standard or specification.

These steels are intended for fabrication primarily by cold forming and welding as per API Spec 2B. The welding procedure is of fundamental importance and it is presumed that procedures will be suitable for the steels and their intended service. Conversely, the steels should be amenable to fabrication and welding under shipyard and offshore conditions. API Specifications 2W and 2Y cover companion steels providing similar mechanical properties but with improved weldability. This improvement results from a reduction in the maximum allowed chemical composition and is made possible by changes in the method of heat treatment and/or processing.1.2 The primary use of these steels is in tubular joints, stiffened plate construction, and other intersections where portions of the plates will be subjected to tension in the thickness direction (Z direction). Supplementary Requirement S-4 provides for through-thickness (Z direction) testing of the plates by the material manufacturer and specified limits for acceptance. Supplementary Requirement S-1 provides for ultrasonic examination of the plates by the material manufacturer and specifies limits for acceptance.
1.3 For applications where through-thickness properties are important but Z direction testing has not been specified, Supplementary Requirement S-5 provides a low-sulfur chemistry intended to reduce the size and number of sulfide inclusions in the plate. Supplementary requirement S-5 is neither a substitute for S-4 Through Thickness Testing nor a guarantee of a minimum level of through-thickness ductility. Experience indicates, however, that tests of low-sulfur carbon-manganese steels usually show at least 20% reduction-of-area. Accordingly, supplementary requirement S-5 is intended as an alternative to supplementary requirement S-4 when testing is not desired. If tested, low-sulfur steel is desired, then both supplementary requirements S-4 and S-5 should be ordered.
1.4 The notch toughness requirements specified in Section 7 or S-12 are suitable for application below water or above water in areas of temperate climate (14°F minimum service temperature). Cold-formed materials have less toughness due to straining than that of the original flat plate, especially in those areas aged by the attachment welding of stubs or braces. The requirements for plates in Section 7 include a moderate adjustment for losses in toughness due to straining and aging; however, differences in composition or fabrication practices may result in significantly greater degradation than that included. Supplementary Requirements S-7 and S-8 deal with the strainaging problem, and consideration should be given to invoking S-7 and/or S-8 when the strain exceeds 5% or when (Nitrogen x % strain) exceeds 0.040. Supplementary Requirement S-8 provides for testing at the specific temperatures and strain levels of interest and is recommended for all material purchases which exceed the purchasers experience base.
1.4.1 For applications with lower service temperatures, lower test temperatures should be considered. Supplementary Requirement S-2 provides for impact tests at temperatures other than those specified in Section 6 or S-12. S2.1 provides for Drop Weight or Charpy V-notch testing at 60°C. S2.2 provides for such testing at temperatures less than 40°C but other than 60°C.
1.5 Manufacturers desiring to apply the API Monogram to products covered by this specification shall demonstrate to the satisfaction of the American Petroleum Institute a program of education, training, experience, and/or examination assuring the manufacturers personnel are competent in chemical analysis, inspection, testing, and nondestructive examinations required or referenced by this specification.
steels are intended for fabrication primarily by cold forming and welding as per API Spec 2B. The welding procedure is of fundamental importance and it is presumed that procedures will be suitable for the steels and their intended service. Conversely, the steels should be amenable to fabrication and welding under shipyard and offshore conditions. API Specifications 2W and 2Y cover companion steels providing similar mechanical properties but with the advantage of potentially lower preheats, and the availability of API RP 2Z prequalification of HAZ toughness. This improvement results from a reduction in the maximum allowed chemical composition and is made possible by changes in the method of heat treatment and/or processing.
1.2 The primary use of these steels is in tubular joints, stiffened plate construction, and other intersections where portions of the plates will be subjected to tension in the thickness direction (Z-direction). Supplementary Requirement S4 provides for throughthickness (Z-direction) testing of the plates by the material manufacturer and specified limits for acceptance. Supplementary Requirement S1 provides for ultrasonic examination of the plates by the material manufacturer and specifies limits for acceptance. For applications where through-thickness properties are desirable but the expense of extra testing is not considered necessary, Supplementary Requirement S5 provides a low-sulfur chemistry intended to reduce the size and number of sulfide inclusions in the plate. Supplementary requirement S5 is neither a substitute for S4 Through-Thickness Testing nor a guarantee of a minimum level of through-thickness ductility. Experience indicates, however, that tests of low-sulfur carbon-manganese steels would usually show at least 20% reduction-of-area in a Z-direction tension test. Even without S5, API Spec 2H provides a reduced sulfur level, compared to other common structural steels.
1.3 The notch toughness requirements specified in Section 7 or S12 are suitable for application below water or above water in areas of temperate climate [14°F (10°C) minimum service temperature]. Cold-formed materials have less toughness due to straining than that of the original flat plate, especially in those areas aged by the attachment welding of stubs or braces. The requirements for plates in Section 7 include a moderate adjustment for losses in toughness due to straining and aging; however, differences in composition or fabrication practices may result in significantly greater degradation than that included. Supplementary Requirements S7 and S8 deal with the strain-aging problem, and consideration should be given to invoking S7 and/or S8 when the strain exceeds 5% or when (Nitrogen x % strain) exceeds 0.040. Supplementary Requirement S8 provides for testing at the specific temperatures and strain levels of interest and is recommended for all material purchases which exceed the purchasers experience base. For applications with lower service temperatures, lower test temperatures should be considered. Supplementary Requirement S2 provides for impact tests at temperatures other than those specified in Section 6 or S12. S2.1 provides for Drop Weight or Charpy V-notch testing at 76°F (60°C). S2.2 provides for such testing at temperatures less than 40°F (40°C) but other than 76°F (60°C).

These steels are intended for fabrication primarily by cold forming and welding as per API Spec 2B. The welding procedure is of fundamental importance, and it is presumed that procedures will be suitable for the steels and their intended service. Conversely, the steel should be amenable to fabrication and welding under shipyard and offshore conditions.

This specification covers one grade of intermediate strength steel plates, though 2(1/2)in. thick, for use in welded construction of offshore structures. These steels are intended for fabrication primarily by cold forming and welding as per API Spec 2B. The welding procedure is of fundamental importance, and it is presumed that procedures will be suitable for the steels and their intended service. Conversely, the steel should be amendable to fabrication and welding under shipyard and offshore conditions. These steels are suitable for use in selected portions of offshore structures, which must resist impact and plastic fatigue loading. When hot or warm forming or PWHT above ¡F is anticipated for accelerated cooling (AC) or quenched and tempered (QC) plates, S9 should be invoked, (italics added per ASTM A913).
1.2 PRIMARY APPLICATION
The primary use of these steels is for Class "OBO" applications as defined in API RP 2A. API Specs 2H, 2W, and 2Y cover other steels providing improved mechanical properties and toughness for Class ÒAÓ applications and should be used where substantial z-direction stresses are expected.
1.1 This specication covers rolled shapes (wide ange shapes, angles, etc.), having a specied minimum yield strength of 50 ksi (345 Mpa), intended for use in offshore structures. Commonly available Class A, Class B, and Class C beams refer to degrees of fracture criticality as described in section 8.1.3 of API RP 2A, with Class C being for the least critical applications. For special critical applications, Class AAZ shapes may be specied, by agreement, using supple- ment S101.
1.2 Supplementary requirements are provided for use where additional testing or additional restrictions are required by the purchaser. Such requirements apply only when speci- ed in the purchase order.
1.3 When the steel is to be welded, a welding procedure suitable for the grade of steel and intended use or service is to be utilized. For the purposes of welding procedure qualica- tion under AWS D1.1, until AWS cites this specication, use the following:
1.4 When heat straightening, hot or warm forming, or post- weld heat treatment above °F (565°C) is anticipated for Class A shapes produced by methods other than hot rolling, controlled rolling, normalized rolling, or normalizing, supple- ment S9 should be invoked.
1.5 By agreement, this specication may be used as a sup- plement to purchase rolled shapes to other international stan- dards, e.g., Euronorm, ISO, or JIS, in which case references to ASTM A6 may be replaced by the comparable interna- tional standard. Users should note that dimensions and design properties might not be the same as A6 shape designations, and that equivalent sections could be heavier.

1.2
Supplementary requirements are provided for use where additional testing or additional restrictions are required by the purchaser. Such requirements apply only when specified in the purchase order.
1.3
When the steel is to be welded, a welding procedure suitable for the grade of steel and intended use or service is to be utilized. For the purposes of welding procedure qualification under AWS D1.1, until AWS cites this specification, use the following:
a. Matching filler metals (AWS D1.1, Table 3.1) shall be as for Group II.
b. Preheats (AWS D1.1, Table 3.2) shall be as for Category B (or Category D for class A-QST herein).
c. Matching weld toughness (AWS D1.1, Tables C4.2 and C4.3) shall correspond to Class A, B, or C herein.
Alternative preheats (AWS D1.1, Annex XI) may also be used to advantage.
1.4
When heat straightening, hot or warm forming, or postweld heat treatment above °F (565°C) is anticipated for Class A shapes produced by methods other than hot rolling, controlled rolling, normalized rolling, or normalizing, supplement S9 should be invoked.
1.5
By agreement, this specification may be used as a supplement to purchase rolled shapes to other international standards, e.g., Euronorm, ISO, or JIS, in which case references to ASTM A6 may be replaced by the comparable international standard. Users should note that dimensions and design properties might not be the same as A6 shape designations, and that "equivalent" sections could be heavier.
If national and/or local regulations exist in which some of the requirements may be more stringent than in this specification the contractor shall determine which of the requirements are more stringent and which combination of requirements will be acceptable with respect to safety, environmental, economic, and legal aspects. In all cases, the contractor shall inform the purchaser of any deviation from the requirements of this specification which is considered to be necessary in order to comply with national and/or local regulations.
Service categories A, B, and C (SCA, SCB, and SCC) reflect forging geometry and method of incorporation into the overall system, rather than levels of criticality. They may also be designated by the user (purchaser) as described in 4.4 to reflect moderately different but standardized levels of performance.
This specification covers four grades of intermediate strength steel plates for use in welded construction of offshore structures, in selected critical portions which must resist impact, plastic fatigue loading, lamellar tearing. Grades 42, 50, and 50Tare covered in thicknesses up to 6 in. [150 mm] inclusive, and Grade 60 is covered in thicknesses up to 4 in. [100 mm] inclusive.
1.1.1
It is intended that steel produced to Grades 42 and 50T of the basic API Spec 2W, without Supplementary Requirements, although produced in a different manner and of somewhat different chemical compositions, be at least equivalent in minimum performance and, therefore, in service application, to the corresponding grades listed in API Spec 2H. Higher performance (Ie., notch toughness at lower temperatures, or enhanced weldability) typically available with TMCP steel may be achieved by specification of Supplementary Requirements.
1.1.2
These steels are intended for fabrication primarily by cold forming and welding. Welding procedure is of fundamental importance and it is presumed that procedures will be suitable for the steels and their intended service. Because of the characteristic high YS/TS ratio of TMCP steels, users may want to consider welding consumables which avoid under-matched weld metal. Conversely the steels should be amenable to fabrication and welding under shipyard and offshore conditions.
1.2
Due to the inherent characteristics of TMCP method, the plates cannot be formed or post-weld heat treated at temperatures above treated at temperature above °F [595°C] without some risk of sustaining irreversible and significant losses in strength and toughness. If warm forming is required, the tensile and notch toughness properties shall conform to the requirements of the specification. The procedure for verification shall be subject to mutual agreement. The plates may be post-weld heat treated at elevated temperatures not exceeding °F [595°C] providing the test coupons are subjected to a thermal cycle to simulate each fabrication operations, as described in S-9. Verification or simulation is not necessary for heating at temperatures not exceeding 400°F [205°C]
1.3
The primary use of this steel is in tubular joints where portions of the plates will be subject to tension in the thickness direction. (Z direction) Supplementary Requirement S-4 provides for thru-thickness testing of plates by the manufacturer and specifies limits for rejection. The presence of laminations and large non metallic inclusion in these portions of the plates can be extremely damaging. Supplementary Requirement S-1 provides for ultrasonic inspection of those plates by the manufacturer and specifies limits for acceptance. The presence of marinations and large non-metallic inclusions in these portions of the plates can be extremely damaging. Supplementary Requirement S-1 provides for ultrasonic examination of the plates by the manufacturer and specifies limits for acceptance. If Supplementary Requirement S-1 is not employed, it is recommended that a fabrication yard ultrasonic examination of plates prior to fit up be specified by the owner so as to permit placement of any detected laminations in areas free from through-thickness loadings.
1.4
For application where through-thickness properties are important but not of sufficient concern to justify the expense of Z- direction testing, Supplementary Requirement S-5 provides a low-sulfur chemistry intended to reduce the size and number of sulfide inclusions in the plate. Supplement S-5 is neither a substitute nor a guarantee of a minimum level of through thickness ductility.
1.5
The notch toughness requirements specified in Section 6 are suitable for application below water or above water in areas of temperate climate (14°F[-10°C] minimum service temperature). Cold formed materials have less toughness due to straining than that of the original flat plates, especially in those areas aged by the attachment welding of stubs and braces. The requirements in Section 6 take into consideration typical losses in toughness due to straining and aging. Supplementary requirements S-7 and/ or S-8 when the strain exceeds 5% or when (Nitrogen x % strain) exceeds 0.040.
1.5.11
For applications with lower service temperatures should be considered Supplementary Requirement S-2 provides for impact tests at temperatures other than specified in Section 6. S2.1 provides for NDTT or Charpy V-notch testing at -60°C. S2.2 provides for such testing at temperatures less than -40°C but other than -60°C.
1.6
Preproduction Qualification. Supplementary Requirement s-11 and the related API RP 2Z, dealing with CTOD testing of the weld heat-affected zone and with resistance to hydrogen cracking, respectively, address problems which are not normally dealt with in a commodity grade steel specification. These problems are not unique to TMCP steels, but arise because:
a. Users may be expecting higher performance from TMCP steels than is available with conventional steels (e.g., welding with no preheat, or welding with very high heat inputs while retaining the superior notch toughness), and
b. This is a performance specification which accommodates a variety of differentiated steelmaking practices, rather than a recipe which completely describes all particulars of chemistry, process, and quality control (essential variables).

If warm forming is required, the tensile and notch toughness properties shall conform to the requirements of the specification. The procedure for verification shall be subject to mutual agreement. The plates may be post-weld heat treated at elevated temperatures not exceeding °F [595°C] providing the test coupons are subjected to a thermal cycle to simulate each fabrication operations, as described in S-9. Verification or simulation is not necessary for heating at temperatures not exceeding 400°F [205°C] 1.2.2 The primary use of this steel is in tubular joints where portions of the plates will be subject to tension in the thickness direction. (Z direction) Supplementary Requirement S-4 provides for through-thickness testing of plates by the manufacturer and specifies limits for rejection. The presence of laminations and large non metallic inclusion in these portions of the plates can be extremely damaging. Supplementary Requirement S-1 provides for ultrasonic inspection of those plates by the manufacturer and specifies limits for acceptance. 1.2.3 For applications where through-thickness properties are important but not of sufficient concern to justify the expense of Z- direction testing, Supplementary Requirement S-5 provides a low-sulfur chemistry intended to reduce the size and number of sulfide inclusions in the plate. Supplement S-5 is neither a substitute nor a guarantee of a minimum level of through thickness ductility. 1.2.4 The notch toughness requirements specified in Section 6 are suitable for application below water or above water in areas of temperate climate (14°F[-10°C] minimum service temperature). Cold formed materials have less toughness due to straining than that of the original flat plates, especially in those areas aged by the attachment welding of stubs and braces. The requirements in Section 6 take into consideration typical losses in toughness due to straining and aging. Supplementary requirements S-7 and/ or S-8 when the strain exceeds 5% or when (Nitrogen x % strain) exceeds 0.040. 1.2.4.1 For applications with lower service temperatures should be considered Supplementary Requirement S-2 provides for impact tests at temperatures other than specified in Section 6. S2.1 provides for NDTT or Charpy V-notch testing at -60°C. S2.2 provides for such testing at temperatures less than -40°C but other than -60°C. 1.6 Preproduction Qualification. Supplementary Requirement s-11 and the related API RP 2Z, dealing with CTOD testing of the weld heat-affected zone and with resistance to hydrogen cracking, respectively, address problems which are not normally dealt with in a commodity grade steel specification. These problems are not unique to TMCP steels, but arise because: a. Users may be expecting higher performance from TMCP steels than is available with conventional steels (e.g., superior notch toughness), and
b. This is a performance specification which accommodates a variety of differentiated steelmaking practices, rather than a recipe which completely describes all particulars of chemistry, process, and quality control (essential variables). It is intended that supplementary Requirement S-11 shall apply only when specified in advance by the purchaser. In many cases it may be possible to reply on prior data assembled by the steelmaker, provided no essential variables of the process have been changed.

Grade 50 is covered in thicknesses up to 6 in. (150 mm) inclusive, and Grade 60 is covered in thicknesses up to 4 in. (100 mm) inclusive.
1.1.1
It is intended that steel produced to Grades 50 of the basic API Spec 2W, without Supplementary Requirements, although produced in a different manner and of somewhat different chemical compositions, be at least equivalent in minimum performance and, therefore, in service application, to the corresponding grades listed in Sections 5 through 7 of API Spec 2H. Higher performance (i.e., notch toughness at lower temperatures, or enhanced weldability) typically available with TMCP steel may be achieved by specification of Supplementary Requirements.
1.1.2
API Spec 2W steels are intended for fabrication primarily by cold forming and welding. The welding procedure is of fundamental importance and it is presumed that procedures will be suitable for the steels and their intended service. Because of the characteristic high YS/TS ratio of TMCP steels, users may want to consider welding consumables which avoid under-matched weld metal. Conversely, the steels should be amendable to fabrication and welding under shipyard and offshore conditions.

Conversely, the steels should be amendable to fabrication and welding under shipyard and offshore conditions.
1.1.1 It is intended that steel produced to Grades 42 and 50T of the basic API Spec 2W, without Supplementary Requirements, although produced in a different manner and of somewhat different chemical compositions, be at least equivalent in minimum performance and, therefore, in service application, to the corresponding grades listed in API Spec 2H and API 2W.
1.1.2 API 2Y steels are intended for fabrication primarily by cold forming and welding. Welding procedure is of fundamental importance and it is presumed that procedures will be suitable for the steels and their intended service. Because of the characteristic high YS/TS ratio of quenched-and-tempered steels, users may want to consider welding consumables which avoid under-matched weld metal. Conversely the steels should be amendable to fabrication and welding under shipyard and offshore conditions.
1.2 Post Manufacturing Heating Due to the inherent characteristics of quench-and-tempered material, the plates cannot be formed or post-weld heat treated at temperatures above tempering temperature used without some risk of sustaining irreversible and significant losses in strength and toughness. If warm forming is required, the tensile and notch toughness properties shall conform to the requirements of the specification. The procedure for verification shall be subject to mutual agreement. The plates may be post-weld heat treated at elevated temperatures used providing the providing the test coupons are subjected to a thermal cycle to simulate each fabrication operations, as described in S-9. Verification or simulation is not necessary for heating at temperatures not exceeding 400°F [205°C]
1.3 The primary use of this steel is in tubular joints, stiffened plate construction, and other intersections where portions of the plates will be subject to tension in the thickness direction. (Z direction) Supplementary Requirement S-4 provides for thru-thickness testing of plates by the manufacturer and specifies limits for rejection. The presence of laminations and large non-metallic inclusions in these portions of the plates can be extremely damaging. Supplementary Requirement S-1 provides for ultrasonic inspection of those plates by the manufacturer and specifies limits for acceptance. If Supplementary Requirement S-1 is not employed, it is recommended that a fabrication yard ultrasonic examination of plates prior to fit up be specified by the owner so as to permit placement of any detected laminations in areas free from through-thickness loadings.
1.4 For applications where through-thickness properties are important but not of sufficient concern to justify the expense of Z- direction testing, Supplementary Requirement S-5 provides a low-sulfur chemistry intended to reduce the size and number of sulfide inclusions in the plate. Supplement S-5 is neither a substitute for S-4 Through Thickness Testing nor a guarantee of a minimum level of through thickness ductility.
1.5 The notch toughness requirements specified in Section 6 are suitable for application below water or above water in areas of temperate climate (14°F[-10°C] minimum service temperature). Cold formed materials have less toughness due to straining than that of the original flat plates, especially in those areas aged by the attachment welding of stubs and braces. The requirements in Section 6 take into consideration typical losses in toughness due to straining and aging. Supplementary Requirements S7 and S8 deal with the strain aging problem, and consideration should be given invoking S-7 and/ or S-8 when the strain exceeds 5% or when (Nitrogen x % strain) exceeds 0.040.
1.6 Preproduction Qualification. Supplementary Requirement s-11 and the related API RP 2Z, dealing with CTOD testing of the weld heat-affected zone and with resistance to hydrogen cracking, respectively, address problems which are not normally dealt with in a commodity grade steel specification. These problems are not unique to Q&T steels, but arise because:
a. Users may be expecting higher performance from Q&T steels than is available with conventional steels (e.g., superior notch toughness), and
b. This is a performance specification which accommodates a variety of differentiated steelmaking practices, rather than a recipe which completely describes all particulars of chemistry, process, and quality control (essential variables).
It is intended that supplementary Requirement S-11 shall apply only when specified in advance by the purchaser. In many cases it may be possible to reply on prior data assembled by the steelmaker, provided no essential variables of the process have been changed.
1.7 American Petroleum Institute (API) specifications are published as an aid to procurement of standardized equipment and materials. These specifications are not intended to inhibit purchasers and procedures from purchasing or producing products made to specifications other than API, and nothing in any API specification is intended in any way inhibit the purchase of products from companies not authorized to use the API monogram.
1.8 Nothing contained in any API, specification is to be construed as granting any right, by implication or otherwise , for the manufacture, Sale, or use in connection with any method, apparatus or product covered by letters patent, nor as insuring anyone against liability for infringement of letters patent.

However, the Institute makes no representation, warranty or guarantee in connection with the publication of any API specification and hereby expressly disclaims any liability or responsibility for loss or damage resulting from their use, for any violation of federal, state or municipal regulation with which an API specification may conflict, or for the infringement of any patent resulting from the use of an API specification.
1.10 The use of the API monogram is a warranty by the manufacturer to the purchaser that the manufacturer has obtained a license to use the monogram and, further, that the product which bears monogram conforms to the applicable API Specification. However, the American Petroleum Institute does not represent, warrant or guarantee that products bearing the API monogram do in fact conform to the applicable API standard or specification.
1.1.1 It is intended that steel produced to Grades 42 and 50T of the basic API Spec 2W, without Supplementary Requirements, although produced in a different manner and of somewhat different chemical compositions, be at least equivalent in minimum performance and, therefore, in service application, to the corresponding grades listed in API Spec 2H and API 2W.

Supplementary Requirement S-2 provides for impact tests at temperatures other than specified in Section 6 or Supplementary Requirement S-12. S2.1 provides for Drop-Weight or Charpy V-notch testing at -60°C. S2.2 provides for such testing at temperatures less than -40°C but other than -60°C.
1.6Preproduction Qualification. Supplementary Requirement S-11 and Section 3 API RP 2Z, dealing with CTOD testing of the weld heat-affected zone and with resistance to hydrogen cracking, respectively, address problems which are not normally dealt with in a commodity grade steel specification. These problems are not unique to Q&T steels, but arise because:
a. Users may be expecting higher performance from Q&T steels than is available with conventional steels (e.g., welding with no preheat, or welding with very high heat inputs while retaining the superior notch toughness), and
b. This is a performance specification which accommodates a variety of differentiated steelmaking practices, rather than a recipe which completely describes all particulars of chemistry, process, and quality control (essential variables).
It is intended that supplementary Requirement S-11 shall apply only when specified in advance by the purchaser. In many cases it may be possible to reply on prior data assembled by the steelmaker, provided no essential variables of the process have been changed.

The welding procedure is of fundamental importance and it is presumed that procedures will be suitable for the steels and their intended service. Because of the characteristic high YS/TS ratio of quenched-and- tempered steels, users may want to consider welding consumables which avoid undermatched weld metal. Conversely, the steels should be amenable to fabrication and welding under shipyard and offshore conditions.
1.2 Post Manufacturing Heating
1.2.1 Due to the inherent characteristics of quenched-andtempered material, plates manufactured to this spec cannot be formed or post-weld heat treated at temperatures above the tempering temperature used during manufacture without some risk of sustaining irreversible and significant losses in strength and toughness. If warm-forming is to be required, the tensile and notch toughness properties of the finished component shall be verified and the properties shall conform to the requirements of the specification. The plates may be post-weld heat treated at a temperature higher than that used during manufacture, providing the test coupons are subjected to a thermal cycle to simulate such fabrication operations, as described in S9. Verification or simulation is not necessary for heating at temperatures not exceeding 400°F (205°C).
1.2.2 The primary use of these steels is in tubular joints, stiffened plate construction, and other intersections where portions of the plates will be subject to tension in the thickness direction (Z-direction).

1.2.3 For applications where through-thickness properties are important but Z-direction testing has not been specified, Supplementary Requirement S5 provides a low-sulfur chemistry intended to reduce the size and number of sulfide inclusions in the plate. Supplement S5 is neither a substitute for S4, Through Thickness Testing, nor a guarantee of a minimum level of through-thickness ductility.
1.2.4 The notch toughness requirements specified in Section 6 are suitable for application below water, or above water in areas of temperate climate (14°F ( 10°C) minimum service temperature). Cold-formed materials have less toughness due to straining than that of the original flat plates, especially in those areas aged by the attachment welding of stubs and braces. The requirements for plates in Section 7 take into consideration typical losses in toughness due to straining and aging. Supplementary Requirements S7 and S8 deal with the strain-aging problem, and consideration should be given to invoking S7 and/or S8 when the strain exceeds 5% or when (Nitrogen x % strain) exceeds 0.040.

1.3Preproduction Qualification.
Supplementary Requirement S-11 and Section 3 API RP 2Z, dealing with CTOD testing of the weld heat-affected zone and with resistance to hydrogen cracking, respectively, address problems which are not normally dealt with in a commodity grade steel specification. These problems are not unique to Q&T steels, but arise because:

It is intended that steel produced to Grade 50 of the basic API Spec 2Y, without Supplementary Requirements, be at least equivalent in minimum performance and, therefore, in service application, to the corresponding grades listed in Sections 5 through 7 of API Spec 2H and API Spec 2W.
1.1.2
API Spec 2Y steels are intended for fabrication primarily by cold-forming and welding. The welding procedure is of fundamental importance and it is presumed that procedures will be suitable for the steels and their intended service.

1.1 CoverageThreading and Gauging
This specification covers dimensions, tolerances, and marking requirements for API threads and the gauges that control the acceptance criteria for the threads. Thread element gauges, instruments, and requirements for the inspection of threads for line pipe, round thread casing, round thread tubing, and buttress casing connections are included. Thread dimensions shown without specifications (or shown as NA) are not subject to inspection of diameter, ovality, and addendum. Thread dimensions shown without tolerances are related to the basis for connection design and are not subject to measurement to determine acceptance of product.
1.2 CoverageInspection
Thread inspection applies at the point of manufacture prior to shipment, to inspection at some intermediate point, to inspection subsequent to delivery at destination, and to inspection by inspectors representing the purchaser or the manufacturer. The manufacturer may, at his or her option, use other instruments or methods to control manufacturing operations; but acceptance and rejection of the product is determined by the results of inspection made in accordance with the requirements of this specification.
Thread inspection is performed using instruments designed to measure either the functional relationship of multiple thread elements or measure an individual thread element. The inspection requirements include measurements of standoff, diameter, ovality, addendum, taper, lead, height, and angle of thread that are applicable to threads having 11 or less turns per inch (0.45 or less turns per mm). Ring and plug gauges are designed to measure the functional size of an internal or external thread. Individual thread elements listed are measured with one or more specific instruments.
See API 5B1 for additional inspection procedures.
1.3 Application of the API Monogram

The API and ISO standardization committees have produced specifications, testing, and recommended practices for the use of bow-type centralizers, but to date, the petroleum industry does not have standards for the selection and use of solid or rigid centralizers, even though those devices are widely used. Additionally, the industry does not have standardized testing methods to verify functionality and reliability of centralizers. This is a problem for the operator in making an intelligent selection for centralizers to use in the well. Some testing procedures are available, but because they are not standardized, they tend to hinder communication between manufacturers and end users.

Additional field failures in CaCl2 brines have been linked to ingress of acidic gas containing CO2 and H2S and to exposure to air. SCC of martensitic stainless steel (SS), (13 % Cr, 6 % Ni, 2 % Mo) was attributed to downhole leakage of acidic gas [2], whereas SCC of a duplex SS tubing (25 % Cr, 3 % Mo) was attributed to air in the gas cap above column of brine. [3]
To understand the effects of brine compositions on the CRAs, a joint industry project was formed under the auspices of the American Petroleum Institute (API). It has been known as the CRAs in Brine Testing Program. Under its auspices, work has been underway for a number of years on understanding the interaction of brine chemistry and CRAs.
The current paper evaluates the SCC risks of a range of CRAs in various halide brine compositions for the case of exposure to acidic production gas (CO2+H2S). Also evaluated are SCC risks due to air exposure. However, the testing became focused on a group of martensitic stainless steels alloyed with Ni and Mo, that are collectively referred to as modified 13Cr martensitic SS, or alternatively in some publications as super (S13Cr) martensitic SSs. Most tests evaluated the as-received brine, excluding proprietary additives such as corrosion inhibitor or oxygen scavengers. For completeness and comparison, test results provided by member companies in the API program or in the publications are cited; these test protocols may be different from those in the API test protocols hence, where that occurs, significant differences are noted.
particle size distribution (PSD) of relatively large dry solid additives for drilling fluids, especially lost circulation materials (LCMs). Detailed procedures for the utilization of any specific PSD method are not included. The technician should refer to and be guided by the measurement equipment manufacturers instructions. The particulates range in size from approximately one micron to as much as several millimeters in diameter, and are considered granular in shape, i.e. relatively isometric (of similar length, width, and height). The recommendations in this technical report generally are not applicable to the measurement of the PSD of nonisometric (high aspect ratio) materials such as fibers or flakes.

a. the evaluation of a candidate polymer for HT flexible pipe service,
b. the evaluation of a candidate polymer to determine its generic performance envelope/limits.
1.2 SIGNIFICANCE
1.2.1 This Evaluation Standard provides a procedure for determining whether candidate polymeric materials have the property levels necessary for successful use as the internal pressure sheath of an unbonded flexible pipe in high temperature high pressure applications.
1.2.2 For the purposes of this document, high temperatures are defined as those between 130 and 200°C. High pressure is considered to be at least 34.5 MPa ( psi).
1.2.3 This Evaluation Standard also provides a means for comparing the performance attributes of several potential pressure sheath materials for high temperature applications.
1.3 CURRENT STANDARDS
1.3.1 The current standards which relate to the evaluation of polymers for internal pressure sheath applications are:
i) API Specification 17J, Specification for Unbonded Flexible Pipe, First Edition [1],
ii) API Recommended Practice 17B Recommended Practice for Flexible Pipe, Second Edition [2].
1.3.2 These documents address all aspects of unbonded flexible pipe technology relevant to current levels of high temperature service; that is, to 130°C.
1.4 UNITS
Système International (SI) units are used in this evaluation standard. Imperial units may be given in brackets after the SI units.
1.5 SAFETY
The procedures described in this evaluation standard include materials tests requiring the use of high temperature and high pressure conditions, often with hostile chemicals. It is the responsibility of individuals or organisations using the standard to ensure that all appropriate safety procedures are implemented to prevent injuries to personnel and/or damage to equipment or facilities
This document is intended to be read in conjunction with API 17TR9 (under development), which highlights technical and commercial risks associated with high functionality umbilical terminations, the implications of decisions made early in the umbilical and SUT planning, selection and design phases, and provides guidance on specification and sizing of SUTs.
With guidance, owner/operators can avoid unexpected loading conditions and the resulting potential for equipment damage, failure, or leakage (either immediate or delayed leaks) or reduced service life.
This Document and the examples provided give the user guidance for evaluating subsea hydrotesting scenarios where test pressures are often well above maximum allowable operating pressure (MAOP).
There is a need for guidelines on the application of external pressure during the design, validation and operation of subsea equipment. Guidelines are also needed to calculate and/or determine a modification to the working pressure limits at the installed water depth, using the selected equipment API rated working pressure (RWP).
API Technical Report 17TR12 (hereafter API 17TR12) provides guidance for subsea equipment designers/manufacturers to properly account for external pressure (or in some cases, differential pressure) when designing and validating subsea equipment. Additionally, this technical report provides guidance to equipment purchaser/end-user to appropriately select rated equipment for their subsea systems with consideration to the effects of external pressure in addition to internal pressure, including differential pressure across a closure mechanism, and other applied mechanical or structural loads under all potential operating scenarios and functionality criteria.
NOTE API Technical Report 17TR4 (hereafter API 17TR4) provides additional information on the effects of external pressure on stresses generated within subsea equipment for the equipment designer.
API 17TR12 applies specifically to API SC17 equipment. API 17TR12 is to be used as a supplement to the equipment's applicable API product specification (e.g. API 6A, API 17D, API 17G), depending on its specific application, associated regulations, and project requirements. Other API product specifications may elect to adopt this technical report, subject to their component hardware, application-related design constraints and acceptance criteria. Specific subsea recommended practices, standards, and/or specifications may elect to adopt this technical report, also subject to their component hardware and application-related design constraints.
For this technical report, the term "equipment" also applies to the terms "part", "component", "sub-component" or "device" within a subsea system.
The objectives of this document are:
to describe typical examples of the various subsystems and components that can be combined, in a variety of ways, to form complete subsea production systems;
to describe the interfaces with typical downhole and topsides equipment that are relevant to subsea production systems;
toprovide some basic design guidance on various aspects of subsea productionsystems.
This document provides comprehensive guidance on materials and pipe issues regarding the use and operation of PA-11 in flexible pipe applications, typically in production and gas handling applications up to 100ºC.
The document concentrates on the use of PA-11 in the internal sheath of flexible pipes, although similar considerations may also apply to other uses of PA-11 within flexibles, e.g., anti-wear layers, intermediate sheathes and outer sheathes.
The collective goal of this document is to prevent failure of the internal pressure sheath, as a result of ageing and associated loss of mechanical properties, by determining and disseminating the necessary scientific and practical information. API Specification 17J and Recommended Practice 17B(2,3) contain only limited information with respect to these phenomena, and this report supplements and updates the data in the Third Edition of API RP 17B(3).
PA-11 is also used in umbilicals. However, the exposure temperatures are frequently lower than production temperatures. In cases of higher temperature exposure, the information contained in this document applies.
This report documents the results of this study of the risks and benefits of additional penetrations in subsea wellheads below the BOP stack for the purpose of monitoring additional casing annuli for sustained casing pressure (SCP).
Additionally, it is intended to provide a high-level overview of issues that should be considered if a user elects to consider differential pressure in their design, especially in components with irregular geometry and with high stress concentrations. It is not intended to serve as a design specification. This document was prepared in response to a request from the API Subcommittee 17 (SC17).

In the context of design, this covers not only installed subsea hardware (trees, manifolds, etc.), the connecting linkages (jumper arrangements, umbilical systems, etc.), but the fluids to be conveyed, initially from the fluid manufacturers facilities through to bunkering at the host facility and, ultimately, injection or usage at remote subsea locations.
The guidelines set out the framework within which more detailed specifications and procedures should be developed to address the particular features of specific projects and specific installations in respect of design through to production operations and, ultimately, decommissioning. They also indicate what needs to be taken into account and approaches that can be considered, or may be taken, in order that blockages do not occur during the installation, commissioning and operations of a SPS.
It should be noted, however, that the inclusion of a particular approach identified in the document does not imply it is the only approach. Other approaches may be more suitable; this depends on the nature of the SPS and knowledge and experience of the system and fluid designers.
While the aim of this document is to prevent blockages in a SPS, it also addresses the issues of topside equipment which provides the control and chemical injection (CI) services necessary for the operation and performance of a SPS. The correct design of a SPS and the fluids to be utilized, and operation of the SPS including topside fluid bunkering, are critically important in avoiding blockages.
The document is intended for use by chemical suppliers to facilitate the provision of chemicals compatible with existing and intended subsea production systems (SPS) although it is envisaged that use of the document for specification purposes by the operators of such processes, will assist in ensuring the completeness of requests to supply.
The application of the document requires acceptance of the principle that it is the suppliers responsibility to ensure that the chemicals supplied are fit for purpose and safe to use, although it is acknowledged that this responsibility can only be fulfilled if specification of requirements is complete. To this end the document identifies essential information that only SPS designers and operators can provide but without knowledge of which, suppliers should not supply. In the requirements of this document, responsibility for obtaining these items of critical information is placed upon the supplier, in the expectation that designers and operators will respond with their ready provision.
The functional performance of production chemicals is outside the scope of this document.
The assessments and tests specified in this document are not intended to qualify materials for use in an SPS in respect of pressure containment, mechanical load, cyclic mechanical load, or other design parameters.
The chemical-chemical compatibility of production chemicals at their respective application concentrations is also outside the scope of this document as is the effect of any incompatibility on their respective functional performance.
Finally, this document does not consider the health, safety, or environmental (HS&E) implications of deploying a production chemical in an SPS.
NOTE Attention is drawn to the fact that the tests specified in this document can generate data and information about the effect of a chemical/material incompatibility on the integrity of a material used in a SPS, that could necessitate additional testing, outside the scope of this document. Such additional testing should however be undertaken in order to ensure that all possible mechanisms that could threaten the integrity of a production, transportation, or chemical injection system are fully evaluated.

The design verification process focuses on the analytical methods to achieve design verification by calculating the performance limits of a design (system, subsystems, and components), including its service life and material selection. The design validation process focuses on evaluating the potential failure modes of the equipment, the effects/consequences of the failures and defining the appropriate test methods to evaluate the reliability of the equipment against the identified failure modes including validation of material performance. The material section defines the required input parameters for the verification process and recommends the procedures necessary to evaluate the material fitness-for-service in the service environment. Functional testing procedures specific to HPHT equipment are also included in this document.
The design verification and validation protocols in this report should be used as a guide by the various API subcommittees to develop new and revised standards on equipment specifications for HPHT service. This report is not intended to replace existing API equipment specifications but to supplement them by illustrating accepted practices and principles that may be considered in order to maintain the safety and integrity of the equipment. This report is intended to apply to the following equipment: wellheads, tubing heads, tubulars, packers, connections, seals, seal assemblies, production trees, chokes, and well control equipment. It may be used for other equipment in HPHT service.

All 69 flanges were analyzed with an axisymmetric finite element model for each of the four load cases. A postprocessor program was written to calculate the maximum moment capacity for various levels of pressure and tension, based on linear superposition of results. Three different criteria were used to establish the maximum moment, as follows.
a) ASME Section VIII, Division 2 allowable stress categories for the flange with the basic membrane stress allowable established by API.
b) Allowable bolt stresses as established by API.
c) Loss of preload on the ring joint. The results of this post-processing are presented in plots of pressure vs. allowable moment for various tension levels in Section 4.
There are several limitations to this work which should be understood. First, the effects of transverse shear or torsion were not considered in the analysis. Second, the results are for static loading only. No dynamic, fatigue, or fretting phenomena were considered in these results. Third, no thermal stresses or elevated temperature effects were considered for this technical report. Finally, these charts are not intended to replace a critical evaluation of any particular connection in an application where the charts show the flange to be marginal. The charts are intended to be used only as general guidelines for design.
Subsequent to the completion of this work, the 5 1/8 in. 15,000 psi flange was added to API 6A.This new flange was analyzed with the ABAQUS general-purpose finite-element system, using a half-symmetry three-dimensional model in order to find the same data as shown for the other flanges in this technical report.
Details of the analysis of the 5 1/8 in. 15,000 psi flange can be found in the report, Finite Element Analysis of 5 1/8 in. ksi API 6BX Flange, which was prepared for API by Stress Engineering Services. The report, SES Report Number PN, is dated February .
The results in this report are analytical and assume a temperature gradient across the flange as stated in this report. When the flange is insulated on the outside surface, the allowable loads will be higher.
Additional finite element models of five new flanges in API 6A, Sixteenth Edition, , which were not in the Fifteenth Edition, used as a basis for the earlier work, were developed for the combined loading of bolt makeup, internal pressure, tension and bending moment. The API materials were then grouped into four material categories. A thermal analysis was performed (using all 63 axisymmetric finite element models of PRAC 86-212 and the 5 new models) to determine the temperature gradient and resulting thermal stresses at steady state for all four material types at design bore temperatures of 350°F and 650°F.
The post-processor program of PRAC 86-21 (calculating the maximum moment capacity for various levels of pressure and tension based on superposition) was partly modified to include thermal effects and produce separate rating curves on the same chart, based on the leak or loss of preload (on the ring joint) criterion and the stress criteria. The stress criteria used were of two types: a) ASME Section VIII, Division 2, allowable stress categories for the flange with the basic membrane stress allowable established by APL and b) allowable bolt stresses as established by API. The results of this post-processing are presented in plots of pressure vs. allowable moment for various tension levels. These new rating charts were developed at two elevated temperatures for all four material categories in Appendices A, B, C, and D respectively.
See Section 4 for details of the axisymmetric analysis and Section 5 for details of the load capacity calculations.
As in the previous report PRAC 86-21, this report does not address the actual gasket contact loads required to make a seal. This report utilizes the leak or loss of preload (on the ring joint) criterion as in Bull 6AF (PRAC 86-21) and Bull 6AF2 (PRAC 88-21) and not the leakage criteria in report PN 90-21.7
Three-dimensional finite element meshes were generated for each of the 30, Type 6B, and Type 6BX flanges. The bending moment load case required a model of one quarter of the flange which was built up from the smaller segments and the half-bolt superelements. The computer program SESAM was used to obtain the stresses at selected critical flange and hub sections and to determine the gasket reaction due to each of the four unit load cases and the temperature difference load case. Leakage criterion was defined as the load combination which reduces the initial makeup compressive forces in the gasket to zero. The stresses in each defined section were linearized in accordance with the ASME Section VIII, Division 2, procedure to determine the membrane and membrane-plus-bending stress intensities. These stress intensities were checked against the allowables specified in API 6A, and the limiting loads were determined. A computer program LCCP was written to carry out this code check and a LOTUS 1-2-3 Release 3 worksheet was used to plot the load combination charts.
The results of the analysis carried out indicate that the leakage criterion governs the capacity of the smaller flanges in the Type 6B flanges. Leakage was governing for up to 9 in. size flanges in both the 52.5 ksi and 40 ksi makeups for the psi pressure. Leakage was governing the 5 1/8 in. for the higher pressures. Leakage was also found to be governing all Type 6BX flanges for working pressures of up to 5,000 psi. For the 10,000 psi and 15,000 psi flanges, leakage governed only in the larger size range greater than 2 9/16 in. Leakage was governing in all the 20,000 psi API 6BX flanges. The leakage model adopted in this study employs several approximations that have not yet been evaluated. Therefore, the actual leakage forces, i.e. load combinations leading to leakage, may be considerably higher than assumed herein. In reality, the gasket only leaks when its energized capacity is exceeded.
The state of stress at the stress governing hub section under the combined loading of makeup, pressure, tension and bending moment is considered to be secondary. However, when pressure, tension, and bending moments are applied together with the necessary makeup to resist these actions without leakage, the state of stress is rendered primary and, therefore, the allowable stress intensities are halved. This does not seem to be consistent, and it may by far exceed the intention of the code. However, the oversight subcommittee preferred to adopt the conservative route, which may be overly conservative pending further evaluation. Therefore, it may be concluded that when the hub stresses are treated as primary, most flanges do not possess significant reserve strength beyond the leakage condition. In fact, if the leakage condition was somewhat conservative, the stress condition may become governing for most flanges.
The temperature difference of 250°F internal and 30°F external leads to increases in the load-carrying capacity of the flanges. This condition is caused by the compressive forces generated in the gasket due to this temperature difference, and the increase in the allowable stresses when the self-limiting temperature load condition is included. It is recommended that a 3-D finite element, nonlinear material and geometric models of approximately eight flanges be carried out to determine the actual failure mechanism that governs the behavior of these flanges. This includes the prediction of the response of the gasket under increasing load and a more accurate definition of the leakage mechanism. The elimination of the raised face does not significantly reduce the stresses in the hub which caused six Type 6B flanges to fail to meet the ASME criterion for makeup load only (52.5 ksi for 105 ksi bolting). The stress intensities were reduced only by about 5% when the raised face was eliminated, increasing the thickness of the flange by about 10%. The hub thickness for these flanges had to be increased by up to about 27% of their existing thicknesses together with the elimination of the raised face.
The bolt stresses did not govern for any of the flanges analyzed. Bolt stresses are typically within approximately 67% of their yield strength due to makeup, pressure, tension, and bending moment loads. The bolts are expected to be made up to half their yield. The stresses in the bolts due to temperature differences increase by about 5 ksi to 7 ksi, which is about 6% to 8% of the bolt yield stress. The other load conditions (pressure, tension, and bending moments) increase bolt stress by twice the increase due to the temperature difference. Therefore, it is concluded that the bolts will not approach their limiting criterion under the investigated load conditions.
Three-dimensional finite element meshes were generated for the Type 6B, and Type 6BX flanges. The bending moment load case required a model of one quarter of the flange which was built up from the smaller segments and the half-bolt super elements. The computer program SESAM was used to obtain the stresses at selected critical flange and hub sections and to determine the gasket reaction due to each of the four unit load cases and the temperature difference load case. Leakage criterion was defined as the load combination which reduces the initial makeup compressive forces in the gasket to zero. The stresses in each defined section were linearized in accordance with the ASME Section VIII, Division 2, procedure to determine the membrane and membrane-plus-bending stress intensities. These stress intensities were checked against the allow ables specified in API 6A, and the limiting loads were determined. A computer program LCCP was written to carry out this code check and a LOTUS 1-2-3 Release 3 worksheet was used to plot the load combination charts.
The results of the analysis carried out indicate that the leakage criterion governs the capacity of the smaller flanges in the Type 6B flanges. Leakage was governing for up to 9 in. size flanges in both the 52.5 ksi and 40 ksi make ups for the psi pressure. Leakage was governing the 5 1/8 in. for the higher pressures. Leakage was also found to be governing all Type 6BX flanges for working pressures of up to 5,000 psi. For the 10,000 psi and 15,000 psi flanges, leakage governed only in the larger size range greater than 2 9/16 in. Leakage was governing in all the 20,000 psi API 6BX flanges.

In reality, the gasket only leaks when its energized capacity is exceeded.
The state of stress at the stress governing hub section under the combined loading of makeup, pressure, tension and bending moment is considered to be "secondary." However, when pressure, tension, and bending moments are applied together with the necessary makeup to resist these actions without leakage, the state of stress is rendered "primary" and, therefore, the allowable stress intensities are halved. This does not seem to be consistent, and it may by far exceed the intention of the code.

The July 30, , API Subcommittee Meeting Minutes contained the Material Toughness Task Group Charge. It comprised Attachment 6. The charge(s) were:
1. Evaluate the material toughness requirements for API Specification 6A materials, for acceptance worldwide.
2. Perform a survey of the industry and review literature for material toughness values based on technical data and design requirements.
3. Devise a method or action to resolve difference between the European and U.S. opinions on material toughness.
4. Establish work groups to prepare appropriate revisions to API Specification 6A for ballot by June .
1.2 AMENDED TASK GROUP CHARGE
The Task Group came to several conclusions based on the charges:
Charge 1: The Task Group could not evaluate worldwide parameters necessary for acceptance of API Specification6A materials toughness requirements. The justification for other groups Õ requirements was not readily obvious.
Charge 2: The members of the Task Group comprised across section of industry users and manufacturers which have worldwide exposure. The Task Group could not document any materials related failures on equipment whose materials had met the API Specification 6A requirement of15 ft-lb. All documentable failures did not meet the existing requirements. A literature survey revealed no technical data or design requirements which are relatable to API Specification 6A equipment design or usage.
Charge 3: The differences between U.S. and European opinions on material toughness relate directly to a difference in philosophy. There are several differences, but the major difference is that the Europeans feel that the Charpy value relates to design while the U.S. opinion is that the Charpy test is a quality assurance exercise in sorting out Òrogue materials.
Unfortunately, the technical justification of either of the requirements is unclear. The historical evidence indicates that both approaches are conservative since no API Specification 6A equipment failures have been attributed to brittle materials which met the requirements of the existing standards.
Therefore, the Task Group decided to start with a clean sheet and adopted the charge to Determine what is neces-sary to prevent brittle fracture in the field.
Charge 4: With this charge in mind, the Task Group established work groups for:
a. Literature survey.
b. Literature evaluation.
c. Correlations and calculations.
d. Position paper containing proposed changes.
Since end connections usually are included in these tests, they become potential failure points for a re-tested valve assembly. Since end connections are standard products, API has sponsored several research projects to dene the ability of end connections to pass the re test. Ten standard end con-nections of various sizes, types, and pressure ratings weretested in (2). (PRAC-)
Two subsequent research projects (3, 4) in 81(PRAC 80-33) and 82 (PRAC 81-33) resulted in procedures to analytically predict the performance of angedand clamped connections to the reenvironment.
This procedure basically is composed of four parts: (a)predicting the temperature distribution in the ange, (b) predicting the preload loss, (c) predicting the performance of the various seals with the reduced preloads which occur in a re,and (d) predicting whether or not yielding of bolts is likely to occur. Signicant yielding will lead to leakage either during the re or shortly afterward.
A fourth project (PRAC-83-33) (5) evaluated the standard end connections in API Specications 6A (6) and 6D (7)using these analytical procedures.
This report summarizes the results of all the projects. In addition, the appendixes present the analytical procedures used to generate the performance prediction of section 3.
Innumerable factors contribute to flange failures under fire conditions, so it is difficult to formulate hard and fast engineering rules which will ensure fire resistant behavior under all circumstances. It is possible to formulate a generalized methodology to examine enhancements which will increase the probability of survival of API flanges under fire conditions.
1.1 COMPARATIVE TESTING
To provide a basis for comparing protection methods it is necessary to provide consistent testing criteria. Although primarily used for valves, API RP 6F and API Spec 6FA, as well as other test procedures, listed in the following, have been used for testing connection and seal performances.
a. API RP 6F.
b. API Spec 6FA (supersedes API RP 6F).
c. User Modified API RP 6F, (Appendix A).
d. API Spec 6FBShould be considered as the standard test method.
It is not intended that the order of listing indicates test severity.
a. Temperaturesteady state or a high and low range of service.
b. Fluids and gasesstagnant or flowing.
c. Pressurecontinuous or a low and high range.
d. Chemicals and additivesinhibitors, descalers, acidizing, etc.
e. Mechanical requirementsdynamic or static, torque, setting force.
f. Failure criteriapressure leakage, loss of mechanical function, inability to set or retrieve.
Alloy candidates were recommended by AWHEM membership for analysis and confirmed by API's approval of New Work Item No. - in June . Several material suppliers and several AWHEM member companies donated material for testing. Metallurgists on the Task Group screened material certificates to ensure a "normal" chemistry without enhancements for the material candidates listed in Table 1, Table 2, and Table 3.
Alloy chemistries from the material certificates for each of the supplied alloy candidates are provided in Table 6 through Table 16, located at the end of this report for readability.

The success of an FRMS depends on the willingness of diverse stakeholders to alter their behaviors and practices to help mitigate fatigue risk. It is important to bring employees, supervisors and managers early into the process of designing an FRMS. Doing so helps create a buy-in so that they will support and own the FRMS because of the benefits they see for themselves as well as for the overall safety of the workplace.
This recommended practice was developed for refineries, petrochemical and chemical operations, natural gas liquefaction plants, and other facilities such as those covered by the OSHA Process Safety Management Standard, 29 CFR .119
RP 755 was specifically developed for US facilities operating under the OSHA Process Safety Management Standard. Companies voluntarily may also choose to take advantage of RP 755 to design and implement FRMS across their other operations, including upstream and international operations outside the US where fatigue risk can also significantly impact the operational safety. However, doing so is not required under RP 755.
Applies to a workforce that is commuting daily to a job location
RP 755 is specifically designed for employees who live and sleep at their homes during off-duty hours and have normal family-social interactions on a daily basis. These recommendations are not designed for employees who travel to remote locations (e.g. offshore platforms or onshore remote locations) where they live in company-provided accommodations and are isolated from their normal daily family and social interactions.
Research on sleep patterns in offshore platforms and other remote locations shows a greater capacity to adapt to longer sequences of consecutive workdays and maintain adequate sleep when the demands of family and social interactions are not competing with sleep and relaxation time.[2,3]
BakerRisk designed and constructed the Deflagration Load Generator (DLG) test rig used for these tests. The test rig measures 48 ft. long by 24 ft. deep by 12 ft. tall and has three rigid walls, a rigid roof and floor, and one open wall facing the structure being tested, as shown in Figure 1. The interior of the rig is fitted with congestion. The test rig is filled with a propane/air mixture and ignited, causing a VCE.
The specific test environment is controlled through selection of fuel concentration, obstacle geometry, and the distance between the test article and the VCE test rig. The tests were deflagrations with moderate flame speeds such that the wave shape of the blast load would include a rise time to the peak pressure. This type of VCE is representative of typical accidental VCEs at industrial facilities.
The VCE deflagrations are set to vent outside the test rig, toward the test articles. The tents were placed at a sufficient range from the test rig such that three test articles could be tested simultaneously on each shot. The test rig was configured such that the blast loading on the tent could be changed by varying the fuel concentration rather than relocating the test articles.
The tests were originally designed to serve multiple purposes:
Provide data on response of tents to a variety of blast loads ranging from 0.6 to 1.5 psi,
Identify the failure modes for different types of tents, and
Obtain data on tent response to support estimates on the vulnerability of tent occupants.
As the testing was performed it became apparent that the tents being tested could withstand higher pressures than originally envisioned. The test program was therefore modified to accommodate the observed behavior. The development and modifications to the scope of the test program are discussed in Section 2 of this report. The following three series of tests were conducted.
A Series Three types of non-wind rated tents were tested with the long side of the tents facing the blast source. The results of this series of tests are presented in Section 3.
B Series The same types of tents were rotated 90 degrees and retested at higher loads. The results of this series of tests are presented in Section 4.
C Series Three types of engineered tents (designed for 90 mph 3 second wind gusts) were tested at two different pressures. The results of this series of tests are presented in Section 5.
Subsequent to the completion of the API funded tests BakerRisk performed two additional tests to evaluate the DLG performance as internal research. The response of the tents in these internal research tests, including the response of contents added to the tents, is discussed in Section 6.
The Explosion Research Cooperative (ERC) participants voted to release the data from a series of shock tube tests performed under their sponsorship that addressed the potential for the contents of a tent to become airborne. The data, in term of object mass and velocity, are provided in Section 7.
This report presents data only and does not provide any summary or conclusions on the acceptability of a tent siting approach.
It is not the intent of this technical report to explain the benefits of thread root rolling, but the manufacturing process and quality control requirements. This technical report will address the best practices (or recommended practices) to cold root roll API 7-2 threads and identification marking.
This technical report will not address cold root rolling using manual lathes (CW/Manual)a similar process but with different tools used for the pin and box. However, the tools described in this technical report can also be used on manual lathes. The steps to position the CW roll into the thread and the paths the tools move can vary between CNC machines controls.
