A pup joint is Casing, Pipe or Tubing shorter in length than a standard tubular string. This allows for the adjustment and installation of tools and various tubular components when placement downhole is critical for a specific project. A Spacer Pipe is another reference used to identify pup joints. Pup joint features consist of connections, lengths, weights and material grade.

Crossover pup joints are manufactured from seamless mechanical tube. As with all Crossover products, each piece is marked with a distinctive job number and heat number that is fully traceable. A complete range of sizes (1" to 4.5"), weights (standard or heavy wall), and grades (J-55, N-80, L-80, and P-110) are commonly available from stock in 2", 3", 4", 6", 10", and 12" lengths. Lengths up to 20" are available upon request.

Seamless pup joints with premium connections are available in API and exotic alloy grades. Premium ends are threaded by the manufacturer or authorized licensee.

Available with standard or special perforation spacings. Each joint has four rows of ⅜ inch holes drilled longitudinally along the tube. Optional patterns, hole size, and lengths furnished upon request.

Crossover, Inc. handles many types of API Couplings. As a rule, we stock enough of your common couplings which enable us to ship the same day if needed. We carry in stock J-55, L-80, N-80, and P-110. As for sizes, we carry 2 3/8”, 2 7/8” 3 ½”, 4 ½” tubing and some of the casing sizes up to 13 3/8”. Stock connections are EU 8 Rd., Nu 10 Rd., LTC, STC, and BTC. Our couplings are primarily of USA manufacture. If origin is not important, we can source other origins and sometimes beat the USA manufactured cost.

Crossover swages are made from API grades of pipe and mechanical tubing. Rigid quality standards are maintained throughout the manufacturing process by frequent inspection and testing. Raw material quality is assured by our quality assurance program.

A blast joint is shorter in length than standard tubular joint. Built with a heavy wall pipe it is incorporated in the production string to facilitate production across any perforated interval and zone. Blast Joints are manufactured to the following specs connections, lengths, weights and material grade.

Crossover Blast Joints are heavy wall pin by box connectors used in tubing strings and are designed to minimize the effect of external erosive action caused by production fluids. Blast joints are located opposite the location of perforations in the production casing or just below the tubing hanger in sand frac designs. Crossover blast joints are manufactured from seamless mechanical tube in sizes ranging from 2 3/8” to 4 1/2” OD. Any length, grade of material, and threading is available at the customers request. Typical lengths are 10" and 20". Both API and Premium threads are available.

Crossover Coarse Thread Tubing Safety Joint provides for emergency recovery of the major portion of the tubing string should it become necessary to abandon the equipment below. Precision left-hand threads facilitate the release of the joint by right-hand tubing rotation. Equipment requiring right-hand rotation should not be used below the Safety joint.

Crossover Straight-Pull/Shear-Out Safety Joint is used between packers in dual and triple completions and in selective completions using Hydrostatic Single-String Packers. It is also used when rotational releasing is not desired. When ran above the upper packer in a single-string completion, however, the shear value should be adjusted to compensate for any hydraulic conditions that exist when the string is landed, or that are created by well treating operations. They are available in keyed and non-keyed configurations.

Crossover Gas Anchor is an effective and simple design. It will increase oil and gas production, improve efficiency of the lift system, correct artificial lift problems caused by incomplete pump fillage due to gas interference and reduce operating cost.

Crossover Drop Ball Circulating Subs are manufactured from AISI 4140/4145. The standard is pin by box. They are activated by dropping a chrome steel ball, which lands on a sleeve and as pressure increases, the pins in the sleeve are sheared. This causes the sleeve to move down and expose four ports in the side of the sub diverting the fluid flow.

Crossover rotary shoes are manufactured from specially tempered steel to provide the ultimate in toughness and durability. They are used to cut a clearance between the fish and the wall of the well bore. Each shoe is tailored to fit a particular downhole need and normally is run on the bottom of one or more joints of washover pipe. Shoe design is dictated by whether it cuts on the bottom, on the OD, on the ID, or any combination of these. When hole sizes permit, additional clearances can be cut using side ribs, thus providing greater circulation.

Crossover has been servicing the oil country tubular market since 1979. Our commitment to total quality has made us one of the leading manufacturers in the OCTG market. This assurance is recognized both domestically and internationally by major oil producers in their promotion and application of Crossover tubular products.

Pup joints are nonstandard pipes used to adjust the length of the tubular string to meet the exact requirements. In addition, the pup joints are used to change the length of the drill string for drilling operations and easy surface handling.

PURPOSE This specification provides the requirements for manufacturing, inspection and testing of new drill pipe pup joints purchased by Transocean for use on Transocean rigs to maximize longevity and reliability.

SCOPE This specification was developed as a supplement to API Specifications 5DP, RP 7G, and RP 5A5 covering the manufacturing, inspection and testing of new drill pipe pup joints. If conflicts should arise between this specification and other referenced specifications, the provisions of this specification shall apply. All requests for exemptions to the technical requirements specified herein shall be submitted to the Subject Matter Expert, Tubular Equipment for approval prior to the issuance of any Transocean purchase orders for new or used drill pipe pup joints covered by this specification. 2.1

Exemptions 2.1.1 This specification is prepared in a general format and may not encompass all facets of the manufacturing of new drill pipe pup joints. Therefore, a Manufacturer may request exemption (s) for a particular procedure and/or requirement detailed in this specification. The intent of a formal exemption process is to ensure that when this occasion arises that it is properly managed by ensuring the appropriate level of management is aware of the exemption to the procedure and/or requirement. This allows management to assess the risk prior to issuing approval of the exemption. 2.1.2 The Manufacturer Request for Exemption form (Attachment A) is included and made a part hereof. The form may be revised from time to time by Transocean, and shall be used for all exemption requests. All exemption request forms that have been approved by Transocean shall be included in the documentation package specified in Section 14 herein. If a form is submitted for a specific procedure and/or requirement detailed in this specification, purchase orders shall not be issued until approval of the exemption has been granted by the Transocean Subject Matter Expert, Tubular Equipment. If an exemption request is submitted after the purchase order is issued, the production process involved with such request shall not proceed until approval of the exemption has been granted by the Transocean Subject Matter Expert, Tubular Equipment. 2.1.3 It is the responsibility of the Transocean Subject Matter Expert, Tubular Equipment to ensure that all possible avenues have been Hardcopies are printed from an electronic system and are not controlled

given complete consideration prior to authorizing a “Manufacturer Request for Exemption” to a specific procedure and/or requirement contained herein. Approved exemptions may include qualifications and additional requirements to address any risk that Transocean Subject Matter Expert, Tubular Equipment or their representative may identify that is or could be created as a result of the exemption. 2.1.4 All approved exemptions shall have validity for a specific period of time that shall be solely determined by the Transocean Subject Matter Expert, Tubular Equipment. All past and current approved “Manufacturer Request for Exemption” forms shall be retained by the Transocean Subject Matter Expert, Tubular Equipment and the Manufacturer. Verbal approvals of requests for exemptions may be granted in urgent situations but shall be followed up within 24 hours with an e-mail, and then formalized with a signed copy of the exemption request form within seven days after verbal approval. 2.1.5 At the time this standard is approved there will be some drill pipe pup joints in use or in inventory, which do not meet this specification because the drill pipe these are used with does not meet new Transocean specification. Primarily, the difference will be with the pin and box connection, and in most cases, the connections can simply be recut to comply with the new standard when new drill pipe is ordered. Therefore, in most cases, it will not be necessary to order new drill pipe pup joints when new drill pipe is ordered, unless the new drill pipe is a different size. Supply chain management and all business units shall plan and schedule replacement of such drill pipe pup joints when necessary. Exceptions to this specification may be granted from time to time to meet client requirements that are specific to certain drilling programs that are to be carried out under long-term commitments. If the customer provides non-standard drill pipe, they should be advised to provide the non-standard pup joints that are needed. If it becomes necessary for any reason to purchase any drill pipe pup joints that have been previously manufactured, and does not meet all of the requirements of this specification, a request for a technical review of such drill pipe pup joints shall be submitted to the Transocean Subject Matter Expert, Tubular Equipment prior to the establishment of any purchase commitments.

RESONSIBILITY It is the responsibility of anyone who has the authority to purchase new drill pipe pup joints to ensure that any new drill pipe pup joints purchased for use on Transocean rigs shall meet the technical requirements of this specification unless Hardcopies are printed from an electronic system and are not controlled

Definitions 6.2.1 Benchmark Benchmark is a reference mark machined on the pin and box areas adjacent to the shoulder, to determine the amount of material that may be removed from the shoulder when it is refaced. 6.2.2 Prove-Up For the purpose of this specification, the term “prove-up” is an inspection procedure used to verify the nature and extent of an indication (both surface and sub-surface) that is revealed by an automated inspection process. Prove-up involves the use of several types of inspection devices and tools including but not limited to portable compression and/or shearwave ultrasonic devices, electromagnetic examination equipment, dye penetrant materials, and measurements taken by micrometer, dial calipers, etc. If manual “prove-up” inspection fails to reveal the full nature and extent of an indication, the results of the prove-up shall be regarded as inconclusive which are therefore rejectable. 6.2.3 Pipe Body For the purpose of this specification, the term “pipe body” shall be the tube section of a pup joint that is being or has been upset and heattreated to meet API or other special grade requirements as specified in the purchase order. Integral pup joints are machined from one piece of steel, and therefore pipe body is not upset and heat-treated to an API grade specification. Instead, the material of the pipe body in this case is the same material as the tool joints, but the term “pipe body” is still used to describe this part of the pup joint. 6.2.4 Tool Joints One box and one pin tool joint is welded or machine onto each respective end of a pipe body to comprise one finished drill pipe pup joint. Threads and shoulders of specified pin and box connections shall be machined into the tool joints, and sufficient tong space shall Hardcopies are printed from an electronic system and are not controlled

be provided as specified in Table 11. The tong space dimensions specified herein are for the purpose of allowing the proper engagement of tongs to make and break the connection and to provide adequate tong space length to allow a sufficient number of connection re-cuts to maximize the life-cycle of the drill pipe pup joint. Tool joints can be made from forgings or bar stock, the dimensional and material characteristics of which shall meet the requirements specified herein. 6.2.5 Connection Break-In Connection break-in is a process of mating and un-mating newly manufactured pin and box connections for the purpose of coldworking the surfaces of the threads and shoulders prior to delivery of the product by the Manufacturer. The purpose of connection break-in during the course of manufacturing new drill pipe pup joints is to avoid using rig productive time to perform the same procedure on the rig floor. If required, connection break-in shall be prescribed in the Transocean purchase order for new drill pipe pup joints. 6.2.6 Manufacturer The Manufacturer shall be the entity to whom the purchase order is issued for manufacturing drill pipe pup joints to comply with this specification, whether the purchase order is issued directly by Transocean or through a third party.

Transocean (including all of their designated third party representatives) reserves the right of access to the Manufacturer’s facilities and subcontractor’s facilities at any time to witness or observe the manufacturing process, mechanical testing, and all forms of inspection of all drill pipe pup joints made or processed under a purchase order issued by Transocean.

Unique number that is traceable to the applicable mill heat numbers of the pipe body and/or tool joint materials Shoulder-to-shoulder length (ft. and tenths of a foot) Nominal size of pipe body Specified nominal wall thickness of pipe body Specified grade of pipe body material Manufacturer’s name or mark

7.10 The shoulder-to-shoulder length required for all drill pipe pup joints shall be specified in the Transocean purchase order. 7.11 Traceability to the applicable mill heat numbers shall be maintained throughout the manufacturing process of the pipe body and tool joint materials. For welded pup joints, a “position” number or other unique sequence number shall be die-stamped onto the end of the pipe body immediately after upsetting and prior to heat treatment to maintain traceability and to represent the order in which the pipe bodies enter and exit the heat-treatment process. A legible unique number shall be applied to the pipe body after heat treatment and prior to FLUT/EMI inspection, and such unique number shall be maintained onto the pipe body throughout the remaining manufacturing processes in order to maintain traceability. The ends of the pipe to which the pin or box shall be affixed shall be stenciled after heat-treatment and prior to FLUT/EMI inspection in order to satisfy the requirements contained in Section 8.2.5.1. It is realized that the process described above of maintaining traceability by the use and marking of unique numbers to the pipe body may differ from one Manufacturer to another, and as such, specific procedures shall be reviewed and approved by the Transocean representative to ensure they satisfy the intent of this section. For integral pup joints traceability shall also be maintained throughout the manufacturing process by the stamping of a unique number to the end of the bar stock prior to heat treatment. Thereafter, such unique number shall be paint-stenciled onto the pipe body, and shall remain legible until final inspection.

TRANSOCEAN DRILL PIPE PUP JOINT REQUIREMENTS Drill pipe pup joints may either be machined from one solid bar of steel, or by welding pin and box tool joints to a central pipe body. When pup joints are supplied in lengths fifteen (15) feet or less they shall be machined as integral lengths from solid alloy bar stock.

If any lot consists entirely of boxes the tensile test specimens shall be taken from a mid-wall location with the center of the Hardcopies are printed from an electronic system and are not controlled

specimen located at the approximate area of the thread run-out. Results shall meet the specified requirements of API Spec 5DP, for drill pipe tool joints. 8.2.1.2

Charpy Impact Tests 8.2.1.2.1 Integral Pup Joints Charpy testing shall be performed in accordance with ASTM A370 and ASTM E23. Specimens shall be taken from the beginning and end of each heat treatment lot. One set of 3 full size (10.0 x 10.0 mm) specimens shall be taken in the longitudinal direction if wall thickness permits. If full-sized specimens are not obtainable, the largest obtainable sub-sized specimens shall be substituted. All impact tests shall be performed at -20°C. All Charpy Impact values revealed from testing shall met or exceed the minimum values specified in Table 8.2.1.2.1.

Welded Pup Joints Pup joint pipe bodies and tool joints shall be Charpy Impact V-notch tested per ASTM A370 and ASTM E23. Charpy Impact tests are to be taken from the material to be used for manufacturing the pup joint at a frequency of one test per each lot, or one test for every 100, whichever is smaller. This test frequency shall

include material used for both the tool joints and central pipe body. A test shall consist of three specimens. Specimens shall be longitudinally oriented with radially oriented notches. Following upsetting and heat treating, pipe body specimens shall be taken in lots of three from a single location on the pipe body and upset. Pipe body test samples shall be removed from alternate ends of the pipe bodies. Tool joint specimens shall be taken from mid-wall locations. Full-sized (10mm x 10mm) specimens shall be used if wall thickness permits. If full-sized specimens are not obtainable, the largest obtainable sub-sized specimens shall be substituted.

Table 8.2.2.2.A Pipe Body Minimum Charpy Impact Requirements

Hardness Tests – Welded Pup Joints Brinell hardness tests shall be performed after heat treatment of tool joints and shall not be less than 285 HB (30 Rc) and no greater than 341 HB (37 Rc). Brinell hardness tests are to be performed on the finished OD surface of each tool joint.

All bar stock used to manufacture tool joints or integral drill pipe pup joint lengths shall be inspected using the Full Length Ultrasonic Test method (FLUT). The FLUT shall be performed after the bar stock is bored/trepanned and heattreated. The machined surfaces of all connections shall be inspected via wet magnetic particle inspection after all final machining. All surface indications shall be cause for rejection.

The reference standard used for calibration of the ultrasonic equipment used for the inspection of bar stock intended for the manufacture of integral pup joints shall have longitudinal and transverse notches machined in the OD and ID. The notches shall be machined to a depth of 5%, + 1% of the wall thickness of the bar stock prior to machining. The reference standard shall be made from ultrasonically defect-free material with the same pipe body OD, wall thickness, surface finish, and acoustic properties as the product being manufactured. All indication(s) shall be cause for rejection unless it can be demonstrated to the Transocean representative that the material where the

After final machining, a bi-directional wet florescent magnetic particle inspection shall be completed on both the OD and ID of each tool joint to reveal longitudinal and transverse defects. The magnetic particle inspection process shall conform to the requirements specified in ASTM E1444.

After machining, all API connections shall be gauged per API Spec 7-2, Annex H. For proprietary connections, the person who performs gauging shall be qualified by the proprietary connection Manufacturer. The threader shall furnish Transocean with a “Certificate of Compliance” indicating that all connections in the order, comply with the dimensional requirements detailed in API Spec 7-2, or the proprietary connection Manufacturer’s requirements, as applicable. Such certificate shall be included in the document package specified in Section 14 herein.

Internal Upset Geometry The internal upset geometry for internal upset (IU), and internal-external upset (IEU) drill pipe shall have a minimum finished Miu length of 4” (101.6 mm) and a minimum radius of curvature between internal upset and pipe body ID of 8” (228.6 mm). The actual internal upset geometry shall be evaluated using a device, which will provide a trace of the MIU length and radius. In some cases where the ID of the tool joint, and the ID of the pipe body are close to the same dimension and only a slight internal upset is required to manufacture the pipe, the 4-inch minimum length requirement shall be waived upon review and approval by the Transocean representative. The 8inch radius specified in Figure 8.2.3.1 below shall always apply to any internal upset.

Reference Standard A reference standard shall be used to calibrate UT and EMI inspection equipment. The reference standard shall be made from ultrasonically defect-free material with the same nominal OD, nominal wall thickness, surface finish, and acoustic properties as the drill pipe being inspected. Notches shall be machined into the ID and OD surfaces of the reference standard to a depth of 5%, +/- 1% of the specified nominal pipe body wall thickness. The length of each notch shall be between ½ and 1½ inches (12.7 and 38.1 mm). Notches shall be applied on the ID and OD surfaces. They shall be oriented longitudinally (parallel to the pipe axis), transversely (perpendicular to the pipe axis), and obliquely at 11 and 22 degrees to the pipe centerline. Oblique notches shall be machined in both right hand and left hand orientations in both leading and lagging positions as shown in Figure 8.2.5.2. The reference standard shall

Acceptance Criteria Surface indications shall be removed by sanding or grinding. The remaining wall thickness after removal of any surface indications shall exceed 95% of the specified nominal pipe body wall thickness. The removal of any surface indication that results in reducing the remaining pipe body wall thickness below 95% of the specified nominal pipe body wall thickness shall be cause for rejection. Surface indications remaining after grinding to these limits shall also be cause for rejection. Any indication (surface or sub-surface) that produces a signal equal to or greater than the threshold level established with any notch in the reference standard shall be re-evaluated via manual prove-up. Manual prove-up shall include, but not be limited to the use of portable shear wave ultrasonic instruments, electromagnetic examination, or measurements taken by micrometer, dial calipers, etc. The results of such manual prove-up shall be conclusive based on the criteria specified above. All inconclusive indications and mid-body wall indications that cannot be verified via manual prove-up shall be cause for rejection.

Magnetic Particle Inspection (MPI) After final heat treatment, all pipe body ends (from end to 18”) shall be examined via magnetic particle inspection method. The OD surface of the pipe ends shall be examined via wet fluorescent magnetic particle inspection, and the ID surface shall be examined via dry magnetic particle inspection incorporating adequate lighting and mechanical/optical aids to provide adequate visibility of the surfaces to be examined to the satisfaction of the Transocean representative. If scale or other surface condition has formed on the upset surfaces to an extent such that indications may be obscured from view, the surfaces shall be cleaned sufficiently to allow a conclusive inspection to be carried out. In the event that there is a disagreement concerning the suitability of the surfaces to be examined, either before or after cleaning, the Transocean representative shall make the final decision. All surface indications on upsets shall be removed by grinding, sanding, or machining to the limits established by API Spec 5DP, and/or the Manufacturer’s specifications, whichever is the more stringent. MPI shall be performed again after any grinding, sanding, or machining is completed to ensure the indication has been completely removed. Any indications found by MPI after removing the maximum amount of material allowed shall be cause for rejection of the joint. Additionally, any sub-surface indication that cannot be manually proven-up shall be cause for rejection of the joint.

Welding Qualification Welds between the tool joint and the pipe body shall be performed in accordance with an approved welding procedure specification (WPS), procedure qualification records (PQR), and welder performance qualifications (WPQ) written and qualified in accordance with the Manufacturer’s documented procedures that include acceptance criteria to verify the weld design requirements are met. The WPS shall describe all essential and nonessential variables to control before, during, and after the welding process. The PQR shall record all essential variables of the welding process. Tool joint to pipe body

Tensile Tests Tensile tests shall be performed to the weld area material between the tool joints and the pipe body per ASTM A370. Test specimens shall be taken from the mid-body wall area and longitudinally oriented, with the weld within the gage length of the specimen as specified in API Spec 5DP. The tensile capacity of the weld shall exceed 110% of the corresponding pipe body tensile capacity based on the nominal OD at 100% of the specified nominal wall thickness at the specified minimum yield strength of the material. Tool joint to pipe body weld tensile tests shall be performed at the start of production and on one out of every 100 production welds thereafter.

Charpy Impact Tests Tool joint to pipe body welds shall be Charpy Impact Vnotch tested per ASTM A370 and ASTM E23. All Charpy Impact values revealed from testing shall meet or exceed the minimum values specified in Table 8.2.6.3 below. A single test shall consist of three test specimens. Specimens shall be longitudinally oriented with radially oriented notches and shall be taken from mid-wall locations. Specimens shall be notched at the weld line as detailed in API Spec 5DP. Full-sized (10mm x 10mm) specimens shall be used if wall thickness permits. If fullsized specimens are not obtainable, the largest obtainable sub-sized specimens shall be substituted. All impact tests shall be performed at -20°C. Tool joint to pipe body weld Charpy impact tests shall be performed at the start of production and on one out of every 100 production welds thereafter.

Surface Hardness Tests Surface Hardness tests shall be performed on each tool joint to pipe body weld in accordance with API Spec 5DP. Tool joint to pipe body weld surface hardness tests shall be performed on every weld.

Transverse Side Bend Tests Transverse side bend tests shall be performed on tool joint to pipe body welds in accordance with API Spec 5DP. Further, no cracks shall be allowed. There shall be no signs of separation at the fusion line on either the root or the face. Minimal tearing of the edges shall be acceptable, but shall be less than 1/4" (6.35 mm). Tool joint to pipe body weld transverse side bend tests shall be performed at the start of production and on one out of every 100 production welds thereafter. One test shall consist of two specimens removed from the weld zone of the test piece.

Through-Wall Hardness Tests Through-wall hardness tests shall be performed on tool joint to pipe body welds in accordance with API Spec 5DP, and shall not exceed 37 Rc. Three sets of readings shall be taken; one set close to the ID, one set close to the OD, and one set at mid section. Each set shall include at least two readings in each HAZ on either side of the fusion line. One reading from each set shall be in the unaffected pipe and tool joint material.

Tool joint to pipe body through-wall hardness tests shall be performed at the start of production and on one out of every 100 production welds thereafter. 8.2.7 Tool Joint To Pipe Body Welds: Non-Destructive Examination Of Weld Area – Welded Pup Joints 8.2.7.1

Ultrasonic Inspection All tool joint to pipe body welds shall be ultrasonically inspected using the shear wave technique. Ultrasonic instrument sensitivity shall be set using a calibration standard of the same material, curvature, acoustic properties, surface finish and wall thickness as the welded material. The instrument reference level shall be established at 80% FSH (Full Screen Height) using a 1/16” (1.59 mm) diameter drilled hole. The instrument gain shall be set at 6db (6 decibels) above the reference gain setting. The full volume of the weld and heat affected zone (HAZ) shall be scanned twice from the pipe body side of the weld. Any flaw indication that exceeds 50% of the screen height shall be cause for prove-up inspection. Such prove-up inspection shall be carried out at reference. Any nonconclusive indication revealed by prove-up inspection that cannot otherwise be physically or visually examined and subsequently removed shall be cause for rejection of the joint, which includes all sub-surface indications.

Magnetic Particle Inspection (MPI) All tool joint to pipe body weld OD surfaces shall be inspected using the wet florescent magnetic particle inspection process. This inspection process shall encompass the weld zone and a minimum of 6" (101.6 mm) on both sides of the weld. Additionally, a dry magnetic particle inspection shall be performed on the ID surface of the weld zone and a minimum of 6" (101.6 mm) on both sides of the weld. The ID inspection shall incorporate a lighted telescoping inspection mirror. All indications shall be removed by grinding and shall be contoured to the adjacent surfaces to the satisfaction of the Transocean representative. Removal of indications by grinding in all cases shall be confirmed by repeating the magnetic particle inspection of the area in question. Any remaining indications that cannot be removed by grinding, sanding, or machining without reducing the integrity of the weld and/or

Failure of any materials to meet the maximum phosphorus and sulfur content requirements specified herein shall be cause for rejection of the entire heat lot. Failure of any materials to meet the minimum physical and mechanical properties (including but not limited to minimum yield and ultimate tensile strength, elongation, toughness, hardness, side-bend tests, etc.) which are referenced or otherwise specified herein shall be cause for rejection of the entire heat lot. The Manufacturer may elect to re-heat treat a given heat lot or lots in order to meet the specified minimum requirements, but such re-heat treatment shall include a full heat treatment cycle, i.e., quench and temper unless mutually agreed otherwise. When the Manufacturer prefers to only re-temper, the Manufacturer shall demonstrate that the desired results can be achieved via tensile and Charpy testing of sample pieces of the same heat lot that have been re-tempered. If such testing of samples is not practicable or the results of such testing fails to demonstrate re-tempering the heat lot will be successful, the Manufacturer and Transocean representative shall mutually agree on alternative re-heattreatment methods to ensure the heat lot (s) in question will meet the minimum requirements specified herein. If the re-heat-treatment process fails to produce acceptable physical and mechanical properties, or no mutual agreement can be reached, the heat lot (s) shall be rejected.

Tool Joints 9.1.1 The tool joint OD and ID dimensions shall meet the requirement specified in Table 11. 9.1.2 Integral Pup Joints: For pup joints that are made of a single piece of bar stock, the tong space lengths shall be no less than 15 inches. For rigs using high capacity elevators, there will not be sufficient pipe body length to engage such elevators for pups that are only 5 ft. long, shoulder-to-shoulder. In these cases, a different combination of pup lengths needs to be devised to achieve proper space out. 9.1.3 Welded Pup Joints: The pin and box tool joint tong space lengths for pup joints of welded construction shall be manufactured to the lengths specified in Table 11. 9.1.4 Unless specified otherwise in the Transocean purchase order, an 18 degree elevator taper shall be applied to both the box and pin tool joint.

Benchmarks Benchmarks showing the location of the original shoulder shall be applied to each pin and box. Benchmarks shall be visible for a full 360° around the pin or box circumference. The examples of the benchmarks for the pin and box connections that are illustrated in Figure 9.2 below are patented. Therefore, a licensing agreement with the patent holder shall be in place before these specific benchmarks can be machined on tool joints supplied to Transocean. Alternative tool joint benchmarks are subject to prior review and approval by the Transocean Subject Matter Expert, Tubular Equipment prior to machining them onto any tool joints supplied under any Transocean purchase order.

Anti-Galling Treatment A zinc phosphate anti-galling treatment shall be applied to all surfaces of the threads and shoulders of both the pin and box connections to the satisfaction of the Transocean representative. Because this process is not regulated or controlled by any relevant standards, the Manufacturer shall submit their standard operating procedure (SOP) for phosphating connections to the Transocean representative for review and approval. Once approved, the SOP for this process shall be the criteria by which phosphating shall be either acceptable or not acceptable.

Connection Break-In When specified in the Transocean purchase order, connection break-in shall be performed (sometimes referred to as “Make and Break”) using procedures that accomplish three separate and complete make-ups and break-outs of the connection. All three make-ups shall be performed at the maximum recommended make-up torque for the connection as derived by Farr’s Screw Jack Formula specified in API RP 7G. In the case where proprietary connections are specified, the maximum make-up torque value shall be specified by the connection manufacturer/designer. If the torque required to break-out the connection exceeds the make-
