SPECIFICATION FOR REPAIR AND REMANUFACTURING OF WELL CONTROL EQUIPMENT 1

1. Scope1.1 GeneralThis American National Standard specifies requirements for repair, remanufacturing, testing, inspection, welding, marking, certification, recertification, handling, storing and shipping of drill-through equipment used for drilling for oil and gas build under API-16A. When desired this standard can also be voluntary adopted for other well control equipment build under a different specification, but this will not automatically make them API products. This standard defines Repair Service Levels for the below listed equipment and the required equipment traceability that is required to proof compliance. The repair and remanufacturing supported under this standard requires that the associated service conditions of the equipment in terms of internal pressure, temperature and wellbore fluids and ambient temperature limits for which the equipment is designed remains unchanged and is supported by the Original Product Definition.

This American National Standard is applicable to and establishes requirements for the following specific equipment:

a) ram blowout preventers;

b) ram blocks, operators, packers and top seals;

c) annular blowout preventers;

d) annular packing units;

e) hydraulic connectors;

f) drilling spools;

g) adapters;

h) loose connections;

i) clamps.

j) drilling riser

Dimensional interchangeability is limited to end and outlet connections. Typical equipment defined by this American National Standard is shown in Figures 1 and 2.

Recommendations for failure reporting are outlined in Annex B.

This API standard supports the requirements of life cycle management systems for new, individual, API monogrammed products or system parts throughout their functional life cycle.

Parameter Sub clause reference

OSL-1 OSL-2 OSL-3


9. Operating Service Level Minimum Requirements9.1 Requirements for Pressure Testing9.1.1 General

All drill-through equipment shall be subjected to a hydrostatic proof test prior to shipment from the service or repair facility. Water with soluble oil should be used as the testing fluid to avoid corrosion of the drill-through equipment. The type of soluble oil and concentration used shall be documented in the test records. Water can be used in the bore for pressure testing, but requires preservation of the drill-through equipment afterwards.

9.1.2 Hydrostatic Proof/Shell TestDrill-through equipment shall be tested with its sealing mechanisms in the open position, if applicable. When a BOP requires PWHT, regardless if the BOP has traceability to a previous shell proof test, the hydrostatic test pressure shall be tested at a minimum test pressure equal to 1.5 times the rated working pressure. When a BOP requires NO PWHT, and has traceability to a previous proof test, the hydrostatic test pressure shall be tested at a minimum test pressure equal to the rated working pressure. For equipment with end or outlet connections having different working pressures, the lowest rated working pressure shall be used to determine the shell pressure test.

9.1.3 Operating Chamber Pressure TestThe hydraulic operating system test shall be tested on each assembled blowout preventer and hydraulic connector. The hydraulic operating chamber shall be tested at a minimum test pressure equal to 1.5 times the operating chamber’s rated working pressure. When a BOP requires PWHT, regardless if the BOP has traceability to a previous operating chamber pressure test, the operating chamber test pressure shall be tested at a minimum test pressure equal to 1.5 times the rated working pressure. When a BOP requires NO PWHT, and has traceability to a previous operating chamber pressure test, the operating chamber test pressure shall be tested at a minimum test pressure equal to the rated working pressure.

9.1.4 Hydrostatic proof and operating chamber pressure testsThe hydrostatic proof test and the operating chamber pressure tests shall consist of three steps:

a) an initial pressure-holding period of not less than 3 min;b) reduction of the pressure to zero;c) a second pressure-holding period of not less than 15 min.

The timing of the test shall not start until the test pressure has been stabilized within the manufacturer’s specified range and the external surfaces have been thoroughly dried. The acceptance criteria shall be zero leakage.

9.1.5 Closed-preventer testEach ram and annular blowout preventer shall be subjected to a closed-preventer test after the hydrostatic proof test. The hydraulic operating system pressure used shall be equal to or less than the specified operating pressure. The test fluids used for all closed preventer tests shall meet the requirements of 9.1.1.The timing of all closed-preventer tests shall not start until the test pressure has stabilized. Closed-preventer tests shall be performed at low and high pressures, with the low pressure test always preceding the high pressure test.

Jan.VanWijk, 11/12/13,

Need to check the yellow text for correctness.


9.1.6 Low Pressure TestA pressure of 1.4 MPa to 2.1 MPa (200 psi to 300 psi) shall be applied and held below the closed ram or annular packing unit for not less than 10 min after stabilization.

9.1.7 High Pressure TestA pressure at least equal to the rated working pressure of the preventer shall be applied and held below the closed ram or annular packing unit for not less than 10 min after stabilization (see exception for annular packing units in 9.1.9).

9.1.8 Acceptance CriteriaThere shall be no visible leakage.

9.1.9 Annular packing unit testsAnnular packing units shall be tested in two stages. The stage one test shall require pressure-testing on the appropriate size drill pipe in accordance with Table 10.1.The stage two test shall require pressure-testing without drill pipe in the preventer, i.e. on the open hole. The high pressure test for this stage shall be as specified in 10.1.7, except as a minimum it shall be performed at 50% of the rated working pressure of the preventer.

9.2 Elastomeric Seal Requirements If the ram packer or packing element had been replaced prior to the service or repair shop receiving the BOP, and if traceability is available identifying it either being an OEM part or a part that meets or exceeds those requirements, this part may NOT be required to be replaced and will maintain compliance to OSL 1. If no traceability is available, packers and/or packing elements will be quoted for replacement to maintain compliance with OSL 1 requirements. Should the equipment owner require the service facility to complete the OSL and not supply a replacement packer or packing element, the service provider must have a documented process that will allow for the service provider to use an OEM part or a part that meets or exceeds those requirements required for testing to be removed prior to returning to the equipment owner.

All elastomer components used for FAT of units repaired or remanufactured in compliance with 16AR must be fully validated in the BOP design in which they are being used.

9.2.1 Wellbore Sealing Components and Consumables For identification of wellbore non-metallic components, such as ram and annular type BOP Packers, the manufacturer shall have a written procedure for affixing the required codification to the product or its package. All BOP system elastomeric seal elements shall be addressed in the equipment owner’s PM program for the system. If the service provider must provide components to allow for testing those parts/components will be removed after testing when conformance has been proven. Responsibility will be with the equipment owner to add those components when putting the system into service. Traceability must be maintained of the parts added to maintain compliance with the standard and to maintain the equipment’s Operation Service Level. Independent ram assemblies and operators will be treated as a separate component from the blowout preventer. Markings and traceability must still be maintained and can be done through a traceable number by the service provider, permanently stamped or etched into the ram assembly. Ram assemblies and operators will be provided with a separate certificate showing conformance or compatibility (where applicable).

9.2.2 Operating Sealing Components and ConsumablesIdentification of non-wellbore non-metallic components, such as elastomeric seals used in ram and annular type BOP actuation systems, shall be in accordance with the seal manufacturer’s written specification.

9.2.3 Equipment Marking and Storage• Marking and storage of sealing components of BOP systems shall be in accordance with API

6A, API 16A, or API 17D, as applicable, including identification marking of elastomeric seals.• Specialized components, including proprietary design BOP seals and packing units, shall be

stored in accordance with the OEM recommendations.

Jan.VanWijk, 11/12/13,

Tricky as there will be no guarantee what will be used.


9.3 Dimensional check For recertification all API and sealing dimensions should be within product definition tolerances. From the structural side, one needs to look for severe corrosion on the body which might weaken the part. In the event there is no hot work and hence no PWHT; the product definition owner must establish acceptable “wear tolerances”. In this instance the BOP would be “endorsed” as suitable for service.

Function & Fit – terminology

Dimensional checks shall include at a minimum the following:

1. Wear and sealing surfaces (e.g. – Dimensionals of cavities) 2. Flange and Bore Dimensions3. Pressure Retaining Components4. Any Critical Areas per the Product Defnition

Dimensional must be documented and approved by a supervisor who is deemed competent and can assure the technician is competent to record and take measurements in accordance with the established QMS.

9.4 NDE – Initial Inspection The following inspections shall be performed before proceeding with remanufacture of equipment.

All wetted surfaces shall be MPI or DPI inspected.All weld necks shall be MPI or DPI inspected.External surfaces shall be visually inspected and any anomalies further investigated with MPI or DPI.Unacceptable indications found with MPI or DPI shall be removed. Reference API-16A, section 8.5.1.9.4

If full weld records are not available it is advisable to acid etch the BOP to determine any previous weld repair.

Reference MPI as part of the non negotiable list..

Metallic materials exposed to well bore fluids and gasses shall meet the design requirements of NACE MR0175 / ISO 15156 does allow shear blades not to be Sulfide Stress Cracking (SSC) resistant. Suitability of the shear blades that do not comply with the hardness limitations and its potential influence on the sealing capability in SSC environment is the responsibility of the user.

Meeting NACE MR0175 / ISO 15156 for prevention of Sulfide Stress Cracking (SSC) can be achieved by: Deployment of the Well Control Equipment in a non-SSC environment The use of the WCE in an inhibited fluid environment. Material hardness shall not exceed 22HRC and care must be taken when hardness

These specifications shall include the following physical tests and limits for acceptance and control:a) hardness in accordance with ASTM D 2240 or ASTM D 1415;b) normal stress-strain properties in accordance with ASTM D 412 or ASTM D 1414;c) compression set in accordance with ASTM D 395 or ASTM D 1414;d) immersion testing in accordance with ASTM D 471 or ASTM D 1414.

10.5 Base metal material IdentificationIn order to start the repair and remanufacturing process control must also be established over the material properties.

Original Material Test Records (MTRs). If no original Material Tests Records are available, the following must be tested and documented to establish material identification:1. Determining hardness and approximant tensile values2. Determining Chemical composition 3. Engineering judgment based on service/field experience

The hardness of a material is in principle related to the UTS and not to the YS. Yield Strength and tensile strength show a linear correlation with hardness for most steels. However, for steel that shows evidence of strain hardening, a lower strength can be measured for a given hardness. At low hardness and low strength levels, there can be a non-linear relation between strength and hardness.

If uncertainty exists with respect to the material specification, it is required to validate the material properties per the RSL.

Equivalence under ASME BPVC Section II, Part C, or AWS filler metal specifications shall not be considered adequate for substitution without requalification. Recrushed slag is not permitted for welding pressure-containing parts.

Combining two or more welding processes that use alloy filler metals of different nominal compositions requires qualification as a combination procedure.

When joining dissimilar ferritic steels (P-1 though P-5), the filler metal shall conform to the nominal chemical composition of either base metal or an intermediate composition. However, when attaching nonpressure parts to pressure parts the filler metal chemical composition shall match the nominal chemical composition of the pressure part.

For joints between similar materials, the chemical composition of backing materials shall match the nominal base metal chemical composition.

Temporary attachments welded to the base metal shall be compatible with the base metal and welded in accordance with a qualified weld procedure. Temporary attachments shall be removed by gouging or grinding and the base metal restored to its original condition before final heat treatment (if required), pressure testing, and final acceptance.

11.4 Welding specification requirements The minimum requirements of each weld joint, weld repair, or weld buildup in a weldment shall be defined

by a weld specification (WS) and approved by engineering before welding. The WS shall determine the qualification requirements of all WPSs used in the well process. Each weld joint, weld repair, or weld buildup shall be made with WPSs that have been qualified to meet or

exceed the mechanical properties specified by the WS. Any deviation from the WS and the use of procedures that do not guarantee the mechanical properties as

required in the OPD shall be fully documented and approved by the OEM product lead engineer or Remanufacturer lead engineer.

When PWHT is required, the WPSs shall be capable of producing the WS specified mechanical properties in each weld joint, weld repair, or weld buildup after all required production or repair post weld heat treatments.

When it is necessary to repair defects or machining errors in previously post weld heat-treated weldments, the weldments shall be capable of meeting the WS specified requirements after all PWHT cycles.

Capability shall be established by qualifying WPSs for both, the shortest and longest PWHT cycle times at temperature using the same parameters used in the original WPSs (base metal, filler metal, process, etc.

For the hardenable low alloy steels, the shortest PWHT cycle shall be specified in the OPD (x hours at temperature). The longest PWHT cycle shall be x hours plus x hours multiplied by the number of cycles necessary to equal or exceed the cumulative time-at-temperature to which the weldment will be exposed. However thicker joints may require longer PWHT times.

When the weld metal hardness is below the minimum required by the WS, or the parameters used in the previously used WPSs are unknown, or the mechanical properties from the weld are not traceable through the approved PQR, the entire weld shall be removed and rewelded with WPSs qualified in accordance with the OPD.

When it is not possible to qualify WPSs for the required number of 4-hour PWHT cycles, the OEM product lead engineer or Remanufacturer lead engineer shall provide a disposition, guaranteeing the minimum material specifications and weld and HAZ composition, before any welding is performed.

Before welding commences on any component or part, verification and implementation of the correct and approved manufacturer / remanufacturer written welding procedure specification (WPS), the supporting procedure qualification record (PQR), the use certified equipment required to control the fusion welding process and Post Weld Heat Treatment (PWHT) process shall be validated and recorded

b) Records:Records of welder performance qualification (WPQ) tests shall be in accordance with ASME BPVC Section IX.

c) Position qualification:Welders shall be qualified for the welding position applicable for the fusion welding process as defined in AWS DS1.1.


11.6 Materials11.6.1 Base materials

The base metals used to manufacture or repair shall be in compliance with the OPD. The metals used for procedure qualification test coupons shall meet but not exceed the material

specifications and material composition requirements of the base material as defined in the OPD and used in the product.

The base metals of all products to be weld repaired or built up shall be positively identified before weld repairs are performed. The chemical composition and material properties of the base metal shall be traceable by component serial number, engineering drawing, manufacturing records, repair records, or other means, to a mill certificate and mill test report.

When Positive Material Identification (PMI), (Spark Emission Spectrography), is required to determine the material composition, a qualified laboratory using industry-accepted practices and techniques shall perform the analysis. Consideration shall be given that the analysis is made from one or more samples of the original base metal. This includes the substrate of previous weld repairs, buildups, or other areas that are not previously deposited weld metal. A suitable etchant, such as specified in ASME IX QW-470, can be used to determine that these areas are in fact original base metal. The areas, from which metal must be removed for chemical analysis, shall be approved by the OEM product lead engineer or Remanufacturer lead engineer and shall be restored by welding with an approved WPS when required.

If the material specifications are not positively traceable to a material certificate of the base material, test coupons must be taken from the base material to reestablish establish those in order to qualify the WPS under ASME IX. The areas, from which metal must be removed for testing, shall be approved by the OEM product lead engineer or Remanufacturer lead engineer and shall be restored by welding with an approved WPS.

Equivalent P-Number (EP) groupings for the purpose of procedure qualification are not permitted for any of the hardenable materials referenced in this standard (8630M, 4130, F22, etc), because these materials have differences in hardenability, temper resistance, and product heat-treat conditions that require different PWHT cycles to guarantee the required mechanical properties.

Only when the mechanical properties of each component member do not require being equal, then combinations of these materials may be welded, provided the WPSs used and qualified to weld them are qualified separately. This requires a separate PQR test weld to be made using the higher PWHT temperature of the two materials for welding each of the two materials to themselves. This ensures that the HAZ of the more temper resistant and hardenable material meets the maximum hardness and mechanical properties requirements of the design.

WPSs shall be qualified on the base material specification and shall meet the minimum yield and maximum yield strength requirements defined in the OPD.

Metals that do not appear in ASME IX QW-422 as either an S-Number or a P-Number metal are considered “unassigned metals” and shall be qualified separately, except as otherwise permitted in QW-420.1 for base metals having the same UNS numbers. Unassigned metals shall be identified in the WPS and on the PQR by specification, type, and grade or by chemical analysis and mechanical properties.

Procedures qualified with P-Number materials are qualified to weld all P-Number and S-Number metals of the same grouping. However, the S-Number materials listed in ASME IX QW-422 shall not be used to qualify procedures (See ASME IX, QW-420.2).

When the WS calls for welding materials of different mechanical properties (heat treatment condition, strength levels, etc.), the material with the lesser properties shall meet or exceed the mechanical properties specified in the WS.

11.6.2 Filler materials Welding consumables shall conform to the American Welding Society's or manufacturer's specifications.

The manufacturer shall have a written procedure covering the storage, segregation, distribution, and return of all welding consumables. Filler metal identity must be maintained including Fluxes. Materials shall be stored and used as recommended by the manufacturer of the welding consumable. Controls shall be in place to ensure recovered flux, when allowed, is not contaminated in the recovery process and that the process meets the flux manufacturer’s requirements for protection from moisture.


Storage and baking of welding consumables shall be carried out in separate ovens. The ovens shall be heated by electrical means and shall have automatic temperature control. Welding consumable storage and baking ovens shall have a visible temperature indicator.

The deposited weld metal mechanical properties, as determined by the procedure qualification record (PQR), shall meet or exceed the minimum specified mechanical properties for the base material.

Welding rods, electrodes, fluxes, filler metals, and carbon and low-alloy steel welding consumables containing more than 1% nickel shall not be used for welding products required to meet the maximum hardness requirements under NACE MR0175.

Welding consumables containing more than 1% nickel may be used for welding of products that do not require to meet the maximum hardness requirements under NACE MR0175.

AWS/ASME classified filler metals that are qualified with the WPS for a given number of postweld heat-treat cycles shall be listed in the WPS by either the trade name or the classification number.

Unclassified filler metals, which are so qualified, shall also be listed on the WPS and PQR by trade name or nominal chemical composition of the weld deposit. The nominal chemical composition of such deposits shall be taken from either the PQR test weld or the manufacturer’s certificate of compliance.

The certificate of compliance for SAW filler metals shall show that the deposit was made with the same flux as that used on the original PQR test weld.

Since the purpose of the testing for classification is different than it is for procedure qualification (multiple PWHT), the ASME/AWS SAW flux classification system shall not be used to document the SAW flux-wire combinations used on WPSs that are qualified for welding any of the hardenable materials like (8630M, 4130, F22, etc). The WPSs for these materials shall identify both the flux and the wire separately by brand name and the manufacturer’s designation. If the wire is classified and the flux is not, then the flux must be identified on the WPS by the manufacturer’s designation.

If ASME/AWS SAW flux classification does not give assurance that the deposit will meet the 1% maximum nickel requirement of NACE MR0175, or that the deposit will develop the required mechanical properties after more than 1-hour post weld heat treatment the qualification is not acceptable.

The deposited weld metal mechanical properties (after post-weld heat treatment(s), if applicable) shall meet or exceed all the minimum specified mechanical properties of the WS, defined in the OPD.

11.6.3 Repair welds and PWHTRepairing a PWHT’d component without PWHT requires that the repair meet all applicable construction code requirements.

When repairs are made to cladding or overlay welds on low-alloy steels without subsequent PWHT, a minimum remaining clad or overlay thickness of 3/16 in. (5 mm) [API-RP 582] is recommended but all cases it is required to demonstrate that no new HAZ is formed in the base metal with thinner overlay.

The minimum left over is what is qualified under the WPS. The parent material is not affected by the cold weld repair. Some go down as 0.080 in. for min overlay thickness depending on the used process. You have to proof that no new HAS has been formed in the base material.

Exemption of code required PWHT for ferritic materials based on the use of austenitic or nickel-base fillermaterials is not permitted.

All repair welding shall be carried out in accordance with the manufacturer's written specification. All major repair welds to pressure-containing members performed subsequent to original heat treatment shall be mapped. Weld maps shall contain the following Information, at a minimum:Part Sketch denoting weld Repair AreaPart NumberSerial numberWelder’s nameWelders Stamp NumberPT / MT Report Number of verification of Defect Removal WPS usedFiller Material Heat/Batch/LotWeld Flux Heat/Batch/Lot, if used


Number PWHT Hours usedNumber PWHT Hours remaining

Welding and completed welds shall meet the requirements of Section documentation?.

The post-weld heat treatment of the test weldment and the production weldment shall be in the same range as that specified on the WPS. Allowable range for the post-weld heat treatment on the WPS shall be a nominal temperature of ± 14 °C (± 25 °F).

Within the defined bandwidth, the actual PWHT temperatures in combination with the heating and cooling rates can vary between the various WPSs, however the stress-relieving heat-treatment(s) time(s) at temperature(s) of parts shall be equal to or greater than that of the test weldment.

When a weldment requires postweld heat treatment, it shall be performed in accordance with WPSs that are qualified to meet the WS specified requirements after all required production and repair PWHT cycles.

WPSs to be used for welding hardenable materials (8630M, 4130, F22, etc) shall be qualified as follows: Weldment 1 shall be post weld heat treated one time. Depending on the thickness of the joint, the minimum

time at temperature shall be specified in the OPD (x hours), and the temperature shall be < 25 °F below the PWHT temperature. Heating and cooling rates above 800°F shall be at the upper boundary.

Weldment 2 shall be post weld heat treated such that the minimum cumulative time at temperature equals or exceeds minimum time at temperature (x hours) plus x hours multiplied by the number of PWHT cycles necessary to equal or exceed the cumulative time-at-temperature to which the weldment will be exposed. The temperature shall be < 25 °F above the PWHT temperature given for the specific materials to be welded. Heating and cooling rates above 800°F shall be at the lower boundary.

The PQR post weld heat treatment cycle shall be considered sufficiently representative of the production post weld heat treat cycle if a comparison of the PQR PWHT chart with the production PWHT chart shows that:

a) All welds and critical PWHT sections reached the soak temperature specified in the WPS at the same time (±15 minutes) and were held within the allowable temperature range for the time range specified in the WPS, or

b) The last weld to reach temperature was held within the allowable temperature range for the minimum time specified in the WPS, the first weld to reach temperature was held within the allowable temperature range no longer than the maximum time specified in the WPS, and none of the critical PWHT sections exceeded the allowable temperature range at any time.

WPSs that are qualified with the above-specified PWHT cycles or meet the requirements do need not be validated with a furnace survey. However, WPSs that are qualified with PWHT cycles different than the PWHT cycles specified in the OPD do not meet the requirements and shall be validated with a furnace survey.

When a furnace survey is required to validate the production/repair PWHT cycle, it shall be performed as follows: The survey shall be made on a weldment that represents the largest weldment on which the WPSs will be

used. The survey shall be conducted with thermal couples attached directly to each weld joint, buildup, and

critical PWHT section in the weldment. An accurate thermal couple attachment-unit (TAU) and redundant thermocouples should be used to ensure that accurate readings are obtained in these critical areas.

Note: thermal couples shall not be installed on areas that are outside the heated zone of subsequent PWHTs.

Post weld heat treating equipment shall be properly calibrated and meet the requirements specified by the equipment manufacturer, the applicable code, or the remanufacturer, whichever is more stringent.

Post weld heat treatment may be performed locally or in a furnace. Local post-weld heat treatment shall consist of heating a circumferential band around the weld at a temperature within the range specified in the qualified WPS. The minimum width of the controlled band at each side of the weld on the face of the greatest weld width shall be the thickness of the weld or 50 mm (2 in) from the weld edge, whichever is less. Heating by direct flame impingement on the material shall not be permitted.


When spot repairs of finished-machined parts are post weld heat treated locally, special fixtures and pre- and post-heat treating procedures should be used to minimize the distortion that can occur, particularly on finished-machined parts having a low ratio of wall thickness to diameter.Distortion effects can be minimized when background heating is applied to the entire circumference of the part during the post weld heat treat cycle, however all local pre- and post weld heat treatments must be in accordance with one or more WPSs qualified to make the repairs.

The total PWHT time applied shall be equal or less than the time for which the WPS is qualified. It is recommended to qualify the WPS for 1.25 times the total required PWHT time at temperature.

11.6.4 PreheatingPreheating, where required, applies to all welding, tack welding, and thermal cutting. Minimum preheatrequirements shall follow the applicable code and recommended practice such as Appendix R of ASME BPVC Section VIII Division 1, Table 330.1.1 of ASME B31.3, and Annex XI of AWS D1.1. Any recommendations or requirements for preheat listed in the relevant code shall be considered mandatory.

Preheating of assemblies or parts, when required, shall be performed in accordance with the WPS. The preheat and interpass temperature shall be checked by use of thermocouples, temperature indicating crayons, pyrometers or other suitable methods. Preheating temperature shall be verified and recorded before any welding is performed. Heating by direct flame impingement on the material shall not be permitted.

11.6.5 Corrosion-resistant and wear-resistant overlaysThe manufacturer shall use a written procedure that provides controls for consistently meeting the manufacturer-specified material surface properties in the final machined condition. As a minimum, this shall include inspection methods/technique for measuring the specified overlay thickness and acceptance criteria.

The calibration intervals shall be a maximum of six months until recorded calibration history can be established by the manufacturer. Intervals may be lengthened (six months maximum increment) or shall be shortened based on the recorded history. Written records shall document the calibration date, procedure used, accuracy, frequency and hardness results.


11.6.7 Quality Assurance Quality ControlThe equipment, materials, and services used in the remanufacturing conforming to this standard shall be consistent with the welding and inspection requirements of the quality plan, order specification, other agreed specifications in addition to this standard and API Q1.

11.9.6.1 GeneralArticle III of ASME Section IX shall apply with additions as shown in this subclause.

11.9.6.2 Bolt, tapped and blind hole repair performance qualificationThe welder or welding operator shall perform an additional repair welding performance qualification test using amock-up hole (refer to Figure 11). The repair welding qualification test hole shall be qualified by radiography accordingto clause 8, or shall be cross-sectioned through the centreline of the hole and both faces shall be examined by NDE inaccordance with clause 8. This evaluation shall include the total depth of the hole.The repair weld qualification shall be restricted by the following essential variables for performance controls.a) The hole diameter used for the performance qualification test is the minimum diameter qualified. Any hole with adiameter greater than that used for the test shall be considered qualified.b) The depth-to-diameter ratio of the test hole shall qualify all repairs to holes with the same or smaller depth-todiameterratio.c) The performance qualification test shall have straight parallel walls. If any taper, counter-bore or other aid is usedto enhance the hole configuration of the performance test, that configuration shall be considered an essentialvariable.


For welder performance qualification, ASME Section IX P-1 base metals may be used for the test coupon in place ofthe low alloy steels covered by this American National Standard (Table 20).

12. Decommissioning

The LCMSP is responsible for determining and documenting and executing requirements for the decommissioning of traceable products in accordance with the Life Cycle Management Plan. The plan and execution shall include:

A. The decision point(s) that will lead to the decommissioning of the equipment. If there are multiple options for the decommissioning of the equipment, they shall be outlines, along with the process for deciding which one will be chosen.

B. A risk assessment of the hazards associated with decommissioning, with a plan to manage the risks appropriately. This risk assessment shall be updated immediately prior to the actual decommissioning process with the risk management plan updated as necessary, to ensure that it is current.

C. A review of the relevant legal requirements of the jurisdiction where the equipment is planned or expected to be decommissioned from, and a plan to satisfy those requirements as part of the decommissioning process. Such requirements shall include, but not being limited to, disposal of hazardous materials.

D. A plan describing how the equipment will be decommissioned. This shall include the steps to be taken before decommissioning, the activities to decommission. And what will be done with the equipment after decommissioning. The plan shall include removing the equipment from the deployed location, unless a case is made within the plan not to do so.

E. Criteria by which success of the decommissioning process is defined.

If it is not possible to remove the equipment, post-decommissioning actions may be required to ensure compliance to the legal requirements – for example environmental monitoring or access control. If such actions are required, they shall be specified in the decommissioning plan.

At the end of the decommissioning process, a report shall be written capturing the date and location of the decommissioning, the parties involved, and the outcome of the decommissioning process, including the criteria by which success was to be measured, as outlined in the plan.All documentation shall be retained and available for a minimum of five years past the date of decommissioning of the equipment. The decommissioning report shall be approved by the LCMSP and the owner/operator and included in the PHF.
