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 regulatory 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 installation. 3. Remove the external mechanical protectors. 4. Lift the BOP with slings installed around the body of the BOP. 5. Install the BOP on a test stump/fixture. 6. Drain the fluid from the operating system. TC

15 7. Remove the 1" ball valves or pipe plugs from the inlet and outlet connections. 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 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 disassemble the preventer. Note: For a 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. c. Replace ram packing according to its physical condition. d. Repair or replace damaged metal parts. TC

16 2. Reassemble the preventer. Note: For a detailed description of assembly, see Part IV, ASSEMBLY. VII.TESTING a. After reassembling the preventer, test the rams and operating system. Refer to Part VII, TESTING for the correct procedure. 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 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 hydraulic pressure to the CLOSE port. 5) Ensure that 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 appropriate 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. Flex Packers and VBRs should be tested with the largest pipe size for that packer. 2) Apply 300 psi hydraulic pressure to the CLOSE port, and observe the OPEN port for leaks. 3) Increase the pressure to 3000 psi 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. 5) Replace the hydraulic line to the OPEN port. TC

17 6) Remove the hydraulic line from the CLOSE port. 7) Apply 300 psi hydraulic pressure to the OPEN port, and observe the CLOSE port for leaks. 8) Increase the pressure to 3000 psi and observe the CLOSE port for leaks. 9) Inspect for leaks between 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.) VII. STORAGE 1. Hydraulically test ram packers with water using the following procedure: A. Preventer 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 operating pressure, and apply 200 psi pressure under the rams. Hold pressure for 3 minutes. Maximum pressure drop is 10 psi 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 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. 1. Open the bonnets and remove the ram subassemblies. TC

18 2. Remove the top seals and packers, then wash the ram subassemblies. 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 P/N 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, dry storage area. a. The preferred storage temperature range for rubber goods is from 40 F to 80 F. TC

19 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. 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. TC
