U BOP Hydraulic Control System The U blowout preventer is designed so that hydraulic pressure opens and closes the rams and provides the means for quick ram change-out. Ram closing pressure closes the rams. When the bonnet bolts are removed, closing pressure opens the bonnet. After the bonnet has moved to the fully extended position, the ram is clear of the body. An eyebolt can be installed in the top of each ram to lift it out of the preventer. Ram opening pressure opens the rams. Following ram change-out, this pressure closes the bonnets. The rams are pulled outward, near the bonnets before the bonnets begin moving toward the preventer body. This assures that the rams never obstruct the bore or interfere with the pipe in the hole. Hydraulic pressure draws the bonnets tightly against the preventer body and the bonnet bolts are reinstalled to hold the bonnets closed.

Tandem Boosters for U BOPs A BOP equipped with tandem boosters can deliver increased shearing force while not increasing the wear and tear on the packers. Tandem boosters approximately double the force available to shear pipe. Since the tailrod of the tandem booster has the same stroke as the BOP’s operating piston, the standard shear locking mechanism can be installed on the outside end of the booster. For information on lock screws and the required spacers, see pages 11, 13, and 15. For information concerning applications where a tandem booster is required, consult your Cameron representative. 7

U BOP Ram Hang-Off Weights and Shear Requirements Hang-Off Weights Hang-off weights are estimated capacities with Pipe Size Pipe Rams hardened top corners of the hang-off rams. This 3-1/2” 300,000 lb (136,078 kg) 4-1/2” 300,000 lb (136,078 kg) enables the rams to dig into the tool joint and 5” 600,000 lb (272,155 kg) provide superior hang-off capacity while still 6-5/8” 600,000 lb (272,155 kg) meeting NACE requirements. For variable bore rams (VBRs) and FLEXPACKER rams, hang-off weights up to 300,000 lb (136,078 kg) on hang-off rams for the lower pipe size in the range, 600,000 lb (272,155 kg) for the larger pipe size in the range.
Drill Pipe Shearing Requirements The minimum shearing configurations needed for each size U BOP to meet the requirements of the second edition of API 16A are listed in the following chart. Each shearing configuration is capable of shearing the corresponding pipe at a closing pressure equal to or less than 2800 psi. For further information on shearing requirements for different pipe sizes and grades, contact your Cameron representative. Minimum Shearing Configurations for the U BOP API Designated Size

Shearing Configuration
U BOP Pipe Rams Pipe rams are available for use in Cameron U BOPs to fit all commonly used sizes of tubing, drill pipe, drill collar or casing within the ranges in the charts on pages 23, 24, and 25. Cameron pipe rams include the following features: • Cameron pipe rams are self-feeding and incorporate a large reservoir of packer rubber to ensure a long-lasting seal under all conditions. • Ram packers lock into place and are not dislodged by well flow. • All Cameron pipe rams are suitable for H2S service per NACE MR-01-75. • CAMRAM™ top seals are standard for all U BOP pipe rams from 7-1/16” through 18-3/4” sizes. Packer part numbers beginning with 644xxx indicate the CAMRAM lipped-plate design. All other packers use standard elastomer material and reinforcement plates. • CAMRAM 350™ packers and top seals are available for high temperature service and for service in which concentrations of H2S are expected.

U BOP Shearing Blind Rams Cameron shearing blind rams shear the pipe in the hole, then bend the lower section of sheared pipe to allow the rams to close and seal. Shearing blind rams can be used as blind rams during normal drilling operations. The DS shearing blind ram can cut larger diameter tubulars or multiple tubing strings regardless of their orientation to the centerline of the ram. A blade seal between the upper and lower faces eliminates the need for moving pipe after shearing. Features of shearing blind rams and DS rams include: • Large frontal area on the blade face seal reduces pressure on the rubber and increases service life. • Cameron SBRs can cut pipe numerous times without damage to the cutting edge. • The single-piece body incorporates an integrated cutting edge. • CAMRAM™ top seals are standard for all U BOP shearing blind rams through 18-3/4”. Part numbers beginning with 644xxx indicate CAMRAM. All other top seals are standard elastomer material. • H2S SBRs are available for critical service applications and include a blade material of hardened high alloy suitable for H2S service. • The Cameron shearing blind ram has a single-piece body with an integrated cutting edge.

U BOP DSI and DVS Shear Rams Dual string interlocking (DSI) shear rams and double V shear (DVS) rams are also available for the U BOP. The interlocking feature of these rams provides the capability of shearing wireline and braided cable with zero tension in the line, while still maintaining a seal. The blades are interlocked by using pockets in the lower ram and arms on the upper ram to prevent any gap between blade surfaces. DSI rams are similar to standard DS shear rams except for the interlock feature. DSI shear rams are capable of shearing tubing, small pipe, braided cable, slickline and solid sinker bar. DVS rams are similar in design to the standard shearing blind rams except that both blades are V shaped and interlocked. The DVS rams are capable of shearing tubing, small pipe, braided cable and slickline.

U BOP Variable Bore Rams One set of Cameron variable bore rams seals on several sizes of pipe or hexagonal kelly. Variable bore rams are available in the size ranges listed in the chart below. All rams listed are suitable for H2S service per NACE MR-01-75. CAMRAM top seals are standard for all U BOP variable bore rams. CAMRAM packers are available in most sizes. Packer part numbers beginning with 644xxx indicate CAMRAM. All other packers are standard elastomer material. The variable bore ram packer contains steel reinforcing inserts similar to those in the Cameron annular BOP packer. The inserts rotate inward when the rams are closed so the steel provides support for the rubber which seals against the pipe.

Flexpackers for U BOPs The Cameron FLEXPACKER ram is designed to close and seal around several diameters of tubing and pipe. These packers can be used in existing Cameron BOPs. Features include: • Stacks of metal inserts bonded into the elastomer move radially in the elastomer as the BOP rams are closed. • As rams are energized, the proper set of metal inserts is forced against the pipe. The top plate of the packer fits the largest diameter of pipe.

Bonnet Seal Carriers for U BOPs The bonnet seal carrier is a bore-type sealing assembly which replaces the face seal used as the previous bonnet seal. Sealing capability is not dependent upon bonnet bolt torque. One seal is captured in a machined bore in the BOP body while the other seal is captured in a machined bore in the intermediate flange. The seal carrier was designed, developed and performance-verified for use in newly manufactured BOPs or as a replacement seal assembly for BOPs where either the BOP body or the intermediate flange requires weld repair on the sealing surfaces.
BOP Size
The bonnet seal carrier can be retrofitted to any U BOP.

6) Remove the hydraulic line from the CLOSE port. 7) Apply 300 psi (20.7 Bars) hydraulic pressure to the OPEN port, and observe the CLOSE port for leaks. 8) Increase the pressure to 3000 psi (207 Bars) and observe the CLOSE port for leaks. 9) Inspect for leaks between the intermediate flange, body, and bonnet. Bleed all pressure from the BOP opening line. 10) Replace the hydraulic line to the CLOSE port. 11) Replace the seals if leaks were observed and repeat the test with new seals. 12) Repeat the procedure for each preventer.
B. Ram Test (After installation and as required by API RP53 or appropriate regulatory agency.) 1. Hydraulically test ram packers with water using the following procedure: a. Install the BOP stack on a prepared test stump or install a test plug below the BOP if on the wellhead. b. Inspect for ram packer leaks at low pressure by closing rams on an appropriate size test mandrel (none if blinds or shears are used) with 1500 psi (103 Bars) operating pressure, and apply 200 psi (13.8 Bars) pressure under the rams. Hold pressure for 3 minutes. Maximum pressure drop is 10 psi (.7 Bars) in 3 minutes. c. Increase pressure slowly to the rated working pressure of the preventer. Hold pressure for 3 minutes. Maximum pressure drop is 100 psi (6.9 Bars) in 3 minutes. d. If rams leak at low pressure or at working pressure, inspect for worn ram packers and replace if necessary. e. Repeat the above procedure for each set of casing, pipe and shear rams.

VIII. Storage A. Preventer 1. Open the bonnets and remove the ram subassemblies. 2. Remove the top seals and packers, then wash the ram subasemblies. 3. Lubricate the ram bodies, covering them with a heavy grease. Caution: DO NOT lubricate the top seals or packers. 4. Do not store the ram subassemblies inside the preventer. Note: Rubber products that have been put into service and that are subsequently stored, will have an unpredictable shelf-life. This is attributable to their varied physical condition when returned to storage, due to the inability to completely remove elastomeric solvents (hydrocarbon contaminates, etc.) and storage in a container filled with air (chemically active gases). 5. Clean the inside and outside machined surfaces of the preventer. 6. Dry with an air blaster until no moisture is left inside or outside the preventer. 7. Inspect the ram bores and the vertical bores for burrs. 8. Remove burrs by touching the surface lightly with a grinder using 36 to 60 grit paper. 9. Lubricate the ram bore with a heavy grease. 10. Lubricate the end and outlet connection faces with a heavy grease, and cover them with flange protectors. 11. Flush the operating system using clean operating fluid. 12. Fill the operating system with preservation fluid Cameron P/N 718100. 13. Install the 1” NPT pipe plugs into the OPEN and CLOSE connections. Caution: DO NOT use the bonnet lifting eyes to lift a preventer. 14. To lift the preventer, use appropriately rated slings around the ends of the body.

B. Elastomers 1. Store rubber products inside a cool, dark, and dry storage area. a. The preferred storage temperature range for rubber goods is from 40°F to 80°F (4.4°C to 26.7°C). b. Rubber goods should be wrapped or otherwise protected from direct exposure to sunlight or artificial light with a high ultraviolet content (such as fluorescent lighting). Do not store in direct sunlight even if wrapped, as overheating will result. c. Store rubber parts in a relaxed position. Do not stretch or hang O-rings and seals. Labels should not be attached to seals with string, wire, or tape, as these items may deform the sealing surface. 2. Use airtight containers when possible to protect against circulating air. 3. Ozone is extremely harmful to rubber. Ensure that there is no equipment in the storage area which may generate ozone, such as mercury vapor lamps, high-voltage electrical equipment, electric motors, or any electric apparatus which produces arcing. 4. Keep the rubber products clean and free of solvents, oil, greases, or any other semi-solid or liquid materials during storage. Rubber goods should specifically be protected against direct contact with: manganese, copper, copper alloys (including brass), polyvinyl chloride (PVC), creosote-impregnated timber, other rubber goods of different rubber compounds, sulphur, and copper napthenate. 5. When cleaning is necessary, rubber goods may be cleaned with either soap and water or methyl alcohol. After cleaning, the rubber goods should be dried at room temperature. 6. Examine the part before installation. Important: Rubber goods taken from storage must ALWAYS be inspected before installation. Rubber goods should not be flexed at temperatures below 40°F (4.4°C). Rubber goods in storage should be inspected every 12 months to ensure that they are still serviceable. a. Ensure that the part does not have a tacky surface or noticeable softening or hardening of the surface. b. Flex the part and inspect with a magnifying glass to ensure that there are no cracks. c. Replace items which show any of the aging signs mentioned above.
