CONTROL MANUAL:5 EDITIONDrilling&WorkoverVOLUME ICHAPTER A-EQUIPMENT SPECIFICATIONS AND REQUIREMENTSdngpiiillgSolj l%udi Ammco1.0 WELL CONTROL EQUIPMENT SPECIFICATIONS AND REQUIREMENTSThis Chapter of the Well Control Manual sets forth the specifications and requirements for Blow Out Prevention Equipment(BOPE)and systems for use in Drilling and Workover Operations.Variations or deviations of BOPE,specifications,arrangement,pressure rating or requirements from this standard requires endorsement of the Well Control Committee,and approval by the Vice President of Drilling and Workover.The enforcement of these equipment standards shall be the responsibility of the Drilling or Workover Rig Superintendent.The Rig Foreman shall ensure that the proper equipment is available and correctly installed.If not specified in these standards all BOP equipment shall comply with API Specifications and Recommended Practices.1.1 Gener al Requir ements:All Drilling and Workover Well Control Equipment shall meet the following requirements:1.1.1 All BOPE(Annulars,Ram Type,Valves,Chokes,Crosses Flexible Lines,Hard Lines and etc.)shall be of forged material,Monogrammed to API Specification 6A,16A,16C,17D or other applicable API Specification as appropriate.1)All equipment in service in Saudi Aramco D&WO Operations must be API Monogrammed.This includes equipment transferred from other regions whether or not it is on a rig already.Monogram and markings MUST be clearly visible through the painted coating of the equipment.Care should be taken to preserve this monogram on the equipment nameplate,flange or body to prevent it being obliterated or destroyed during handling maintenance and use.Additionally,documentation must be available at the rig site reflecting the equipment Serial Number and API Monogram Status.2)Any exceptions to this monogram policy(e.g.;30 1,000 psi annulars)are noted in the section detailing that specific equipment.1.1.2 All major BOPE components including,but not limited to,ram BOPs,annular BOPs,drilling spools,ram blocks,valves,choke and kill lines,choke manifolds,gas busters etc.will have an unique serial or asset identification number assigned at time of manufacture by the ORIGINAL EQUIPMENT MANUFACTURER(OEM).The number must be per manently mar ked in the metal of the component body and should be paint stenciled in a pr ominent and visible location on the equipment.This number must be r efer enced on all accompanying cer tification and r ecer tification documents.Repair number s ar e not acceptable for this r equir ement.1.1.3 Only OEM parts are acceptable when repairing or redressing the BOP,valves,chokes,and closing units.Documentation(e.g.;PO,invoice,certificate of compliance etc.)must be maintained for all parts verifying that they are OEM.1.1.4 Maintenance and testing requirements may be found in Chapter C Maintenance Testing and Certification Requirements of this manual.1.1.5 A drilling spool is preferred for primary choke and kill line installation.However in special cases,such as space limitation,preventer side outlets may be used in lieu of a drilling spool.The diameter of all preventer side outlets must be at least as large as the choke manifold lines.NOTE:Side outlets are used for installation of the lower choke and kill lines on 10K/15K BOPs.Current Revision:JUNE,2014Previous

through-bore size of the preventer stack,tubing head,and any adapters used in the BOP hook-up shall be large enough for the maximum size bit,scraper,liner hanger,packer,plug,cup tester,bowl protector or any other large diameter down-hole tools to be run in the well.1.1.7 The pressure rating of all pressure control equipment(BOP,Valves,Lines etc.)must be greater than the MASP(Maximum Anticipated Surface Pressure).1.1.8 The inboard manual valves on the choke and kill lines are considered master valves and normally would not,except for pressure testing,be closed unless the outside valve(HCR)has failed.1.1.9 Check valves must be installed on normal kill lines but shall not be used on emergency kill lines.1.1.10 The kill line,emergency kill line and choke lines should be flushed and washed out frequently to prevent mud solids settling.1.1.11 BOP assemblies will be dismantled between wells to inspect for internal corrosion,erosion and to check flange bolts.Refer to Chapter C for maintenance procedures and requirements.1.1.12 All Rigs shall maintain a logbook of BOP schematics detailing the components installed.The logbooks shall contain the part number,size,description,serial number(if applicable)and installation date of ram blocks,top seals,ram and annular packers and bonnet or door seals.This is be witnessed and co-signed by the Toolpusher and the Saudi Aramco Representative(see form#1 in Chapter C)of this manual).1.1.13 All ram preventers must be equipped with manual or automatic locking devices,which must be locked whenever the rams are used to control the well.Hand crank,wrench or hand wheel systems are acceptable manual locking devices.1.1.14 All preventers and associated equipment must meet NACE MR-0175/ISO 15156,API Specification 6A,16A or 16C for sour service.1.1.15 A full OEM certification or recertification of the BOP,choke manifold(including chokes)and all related equipment must be performed at the start of the contract and least once every three years thereafter.The r ecer tification must be in accor dance with the r elevant API Specification for r epair/r emanufactur e.The documentation package shall be kept with the equipment and must be available for inspection at the rig site by Saudi Aramco personnel.This includes,but is not limited to:Ram preventers.Annular preventers.Valves on the kill,emergency kill,choke line and choke manifold.Drilling chokes.Kill,emergency kill and choke lines(and line components)including both hard line and flexible hoses.Drilling spools.NOTE:Recertification can only be performed by the OEM or their licensee facility.If recertified by a licensee,the document package shall include a copy of the license issued by the OEM.In-field r ecer tification is not acceptable.Current
