A BOP equipped with tandem boosters can deliver increased shearing force while not in-creasing 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 page 17.
For information concerning applications where a tandem booster is required, consult your Cameron representative.

UM BOP Ram Hang-Off Weights and
Shear Requirements
Hang-Off Weights
Hang-off weights are estimated capacities with hardened top corners of the hang-off rams. This enables the rams to dig into the tool joint and provide superior hang-off capac-ity while still 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 UM BOP to meet the require-ments 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.

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 up-per 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 and UM 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.

Flexpackers for U and UM 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.

IV. Assembly Procedure
A. Part Preparation Prior to Assembly
The work area should be clean and well lighted.
1. Remove all dirt, grit, oil, and contaminates from the ram bore, ram change piston holes, bonnet stud holes, all fluid passageways in the body, and inter-mediate flange. Clean water and detergent should be used for cleaning. High pressure air may also be used if it is dry air.
2. Clean all internal surfaces of bonnets using clean water and detergent. Lubri-cate internal sealing surfaces.
3. Clean pistons, cylinders, and intermediate flanges, using clean water and de-tergent. Lubricate areas that will come in contact with other parts.
4. Lubricate sealing surfaces behind the threads in the bonnet stud holes in the BOP body after cleaning this area.
5. Sealed elastomer containers should not be opened until they are required for assembly. This is to prevent contamination and damage to the seal.

Operation and Installation Procedures
A. Preparation
Prior to the installation of the preventer, ensure that the following requirements are met:
1. The capacity and the pressure rating of the accumulators and the pressure pumps must comply with the API RP53 recommendations or appropriate reg-ulatory agency requirements.
2. Ensure that the ring gaskets are correct for the preventer flange, the hub size, and the pressure rating.
B. Installation
1. Install the preventer, ensuring that the preventer is right-side-up (outlets are below the center of the preventer).
2. Inspect the preventer, the ram subassemblies, and all rubber parts during in-stallation.
3. Remove the external mechanical protectors.
6. Drain the fluid from the operating system.
7. Remove the 1” ball valves or pipe plugs from the inlet and outlet connec-tions.
8. Connect the hydraulic control lines, and flush the operating system with clean fluid.
9. Test for leaks in the operating system (refer to Part VII, TESTING.)
10. Install the rams in accordance with the assembly procedure described in Part IV, ASSEMBLY.
11. While installing the rams, inspect the ram bore and bonnet. a. Inspect the vertical bore for key seating.
b. Inspect the intersection between the vertical bore and the ram bore. Grind out any raised metal surfaces. Do not remove any metal below the original surface.
VI. Maintenance Procedures
A. Routine Maintenance
1. If more than 500 psi (34.5 Bars) hydraulic pressure is required to operate the ram subassemblies when there is no pressure in the well bore, determine the cause and correct any irregularities.
Caution: To avoid damage to the packers, close pipe and variable bore rams only when
pipe is in the preventer.
2. Pressure test and operate the preventer once a week per API RP53 “Periodic Field Testing” or appropriate regulatory agency requirement.
B. Periodic Maintenance
1. Once a year, or every six months in cold weather conditions, completely dis-assemble the preventer.
Note: For detailed description of disassembly, see Part III, DISASSEMBLY. a. Clean all parts. Do not use a wire brush on sealing areas. b. Replace all rubber seals, gaskets, and O-rings.
d. Repair or replace damaged metal parts. 2. Reassemble the preventer.
Note: For a detailed description of assembly, see Part IV, ASSEMBLY.
a. After reassembling the preventer, test the rams and operating system. Re-fer to Part VII, TESTING for the correct procedure.
VII. Testing
A. Hydraulic Operating System
1. Test the hydraulic operating system after installation.
a. Flush the hydraulic operating system with clean operating fluid. b. Test for proper stroking of the rams and operating system.
1) Apply a maximum of 300 psi (20.7 Bars) hydraulic pressure to the OPEN port.
2) Ensure that the rams open.
3) Reduce hydraulic pressure to zero psi.
4) Apply a maximum of 300 psi (20.7 Bars) hydraulic pressure to the CLOSE port.
5) Ensure the rams close.
6) Reduce hydraulic pressure to zero psi. c. Test for leaks in the operating system.
1) Remove the hydraulic line from the OPEN port.
Note: If testing pipe, casing, flex packers, or variable bore rams, be sure that an
appropri-ate size test mandrel is installed into the preventer. DO NOT close the rams on an open hole unless closing pressure is less than 300 psi (20.7 Bars). Flex Packers and VBRs should be tested with the largest pipe size for that packer.
2) Apply 300 psi (20.7 Bars) hydraulic pressure to the CLOSE port, and ob-serve the OPEN port for leaks.
3) Increase the pressure to 3000 psi (207 Bars) and observe the OPEN port for leaks.
4) Inspect for leaks between the intermediate flange, the bonnet, and the BOP body. Bleed all pressure from the BOP closing line.
6) Remove the hydraulic line from the CLOSE port.
7) Apply 300 psi (20.7 Bars) hydraulic pressure to the OPEN port, and ob-serve 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 appro-priate 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.
