1.1 General A. Purpose The purpose of this manual is to provide detailed instructions on how to perform scheduled inspections of Hydril ram blowout preventers when they are not in service. For in-service inspections, refer to the BOP operator's manual. B. Ram BOP Configuration Instructions in this manual are provided for single ram BOPs with one ram compartment . Therefore, if the BOP being inspected has more than one ram compartment, repeat the instructions as many times as necessary. C. Initial Safety Precautions WARNING: DO NOT OPEN THE BONNETS OF A RAM BOP UNLESS THE RAM BOP IS INSTALLED ON THE TEST STUMP OR SECURED TO THE FLOOR. THE WEIGHT OF AN OPEN BONNET CAN CAUSE AN UNSECURED BOP TO TURN OVER. D. Part Identification Parts referenced in this manual are identified by referring to Figures 4-2 through 4-5 in Section 4 of this manual. These figures contain exploded views and parts lists of typical ram blowout preventers, pipe rams, variable rams, and shear rams. However, these figures do not contain part numbers. For part numbers, refer to the part number stamped in the surface of the component. If the component does not have the part number stamped in its surface, refer to the parts list and assembly drawing in the BOP operator's manual. E. Required Equipment Adequate facilities and equipment are required to safely lift and move the assembled ram BOP and to pressure test the BOP. Hydril recommends the lifting configuration shown in Figure 1-1. F. BOP Control System Requirements Opening and closing of the BOP rams is accomplished by applying hydraulic pressure to the Open or Close port on the BOP. When pressure is applied to the Open port, the Close port must be piped in a manner that allows the free flow of operator fluid from the BOP as the pistons move to open the rams. This requirement is the same for the application of hydraulic pressure to the Close port.

Figure 1-1 Ram BOP Lifting Confinguration Use light weight hydraulic oil or a mixture of clean fresh water and a fluid concentrate composed of soluble oil and rust inhibitor. In freezing temperatures (below 0oC /32oF), add antifreeze (ethylene glycol) to any fluid concentrate and water mixtures. [CAUTION: Do not use synthetic fluids or fuel oil. Use of these will result in damage to the seals.] Use clean tap water as bore fluid. G. Cleaning Clean the ram BOP(s) as soon as possible after removing the BOP stack from the wellhead. Remove caked drilling mud and cuttings from the ram compartment(s) and exterior of the BOP with high pressure water or steam. H. Lubrication Lubricate all metal surfaces with light machine oil such as Gulf Harmony No. 46 or Exxon Coray 100 or equivalent. Use Never-Seez thread lubricant or equivalent with a coefficient of friction of .069. Coat all seals and nonextrusion rings with silicone grease or castor oil. CAUTION: Use of petroleum base oil or grease will reduce seal life. I. Part Replacement Only Hydril replacement parts should be used to insure expected performance and service life. Refer to the part number stamped on the part or to the parts lists in your BOP operator's manual.

J. Inspection Records Inspection forms are provided in Section 9. These forms are designed to be used along with the inspection procedures. To make the recording of results easy, each form has step numbers that correspond to the steps used in the inspection procedure. Each form should be treated as a master for photocopying. Make as many copies as are needed.

1.2 How To Use This Manual A. Normal Use This manual is designed to be used in conjunction with the BOP operator's manual for disassembly and assembly instructions, operation specifications, bolt torques, and part numbers. If an operator's manual is not available, contact Hydril Headquarters in Houston, Texas for a copy (refer to Section 10 for address information). This manual is divided into sections for ease of use. The section headings are listed in the Table Of Contents at the front of this manual. To use this manual, turn first to the inspection schedule in Section 2. Find the desired inspection interval on the schedule. The procedure for each inspection on the schedule is found in Sections 3 through 8. Find the inspection form in Section 9, photocopy it, and use it as you follow the corresponding inspection procedure. If the BOP requires major repairs that cannot be made in the field, contact Hydril at one of the Hydril Repair Facilities listed in Section 10. B. Revision Occasionally, Sections 1 through 10 of this manual may be revised. Revisions are identified in two ways. First, by a letter of the alphabet (Rev. A, B, C, etc.) on page 1 of each section and in the Revision Record. The Revision Record follows the Table Of Contents in the front of this manual. Second, the revised portion will be indicated by an 8-pt. grey bar in the margin (see example in the left margin). This bar is intended to aid the user in finding the parts of the section that have been changed from the previous version. Furthermore, to make the updating of this manual easier when revisions are made, whole sections will be replaced rather than individual revised pages. NOTE: The revision letter indicated in the revision box on page 1 of each section should match with the letter shown in the Revision Record. If not, contact Hydril

Company Headquarters. Refer to Section 10 of this manual for the address, telephone, and FAX numbers.

5.1 General A. Purpose The procedures in this section cover the BOP operating test of the Hydril ram BOP. This test verifies that the Open and Close functions of the ram BOP operate properly. B. Inspection Records During the BOP operating test of the ram BOP, records should be kept of the results. Use the Ram BOP Inspection Form located in Section 9. C. Control System Requirements The Hydril ram BOP may be tested with any oil field test pump of sufficient pressure capacity. A 3-posi-

tion 4-Way valve (Open, Block, Close) and a hydraulic regulator should be installed in the output line of the test pump. An opening and closing line is required to operate each set of rams. These control lines are connected to the one-inch NPT ports on the hinge side of the BOP. The regulated pressure source to operate the ram BOP should be from a regulator separate from that used for the annular blowout preventer(s). Any clean, light petroleum hydraulic oil can serve as a hydraulic fluid. Fresh water may be used if water soluble oil is added. Antifreeze must be added to water based operating fluids to prevent serious damage to the operators when used in freezing conditions. CAUTION: Do not use synthetic fluids or fuel oils. Serious seal damage will result.

Inspection Manual Ram BOPs BOP Operating Test

5.2 BOP Operating Test Procedure A. Testing Precautions Take the following precautions to insure the safety of all personnel during blowout preventer testing. 1. Use safety barrier during test operations. 2. Verify that test stump, blind flanges, mandrels, blind hubs, piping, valves, gauges, and related equipment are rated for the test pressures. 3. Check resolution and accuracy of pressure indicating devices. A resolution of one percent of full range and an accuracy of two percent is required. 4. Do the following if a leak occurs, or an unacceptable pressure loss occurs: a. Stop the test. b. Vent pressure from the BOP.

WARNING: STAND CLEAR OF VENTED PRESSURE TO AVOID INJURY. c.

Make necessary repairs and perform the BOP Operating Test again.

B. Tools and Materials required: 1. New API metal ring gasket 2. Light machine oil ( Gulf Harmony No. 46 or Exxon Coray 100) 3. Never-Seez thread lubricant (.069 coefficient of friction) or equivalent 4. Ram BOP Inspection Form (refer to Section 9) C. BOP Operating Test 1. If the ram BOP is already installed on the test stump, continue to Step 2. Otherwise, install the BOP onto the test stump as follows: a. Wipe hubs/flanges, ring gasket, and ring grooves clean with a rag soaked in light machine oil. b. Install the BOP onto the test stump. Lift the BOP using the sling arrangement shown in Figure 5-1.

WARNING: THE RAM BOP IS VERY HEAVY AND BULKY EQUIPMENT. TAKE EXTREME CARE WHEN LIFTING IT. DO NOT PLACE HANDS WHERE THEY CAN BE INJURED BY CONTACT WITH OTHER EQUIPMENT DURING LIFTING AND INSTALLATION OPERATIONS. BE SURE THAT THE LIFTING APPARATUS IS ADEQUATE TO HANDLE THE LOAD. 1) If a clamp is required to make up the

Tighten clamp nuts and bolts alternately, side to side, during installation to bring the clamp haves together uniformly. Strike the clamp occasionally with a sledge hammer during tightening to ensure proper seating of the clamp on the hub. Contact clamp manufacturer for torque values. 2) If studs and nuts are required to make up the connection between the test stump and the ram BOP, apply Never-Seez thread lubricant to the threads prior to installation. Refer to the ram BOP operator's manual for the torque value. Blind off all outlet connections with appropriate hardware. Outlet clamps (if required) are installed in the same manner as end connec-

tion clamps. d. Connect hydraulic test pump to ram BOP. Refer to Paragraph 5.1.C. 2. Open the ram BOP bonnets. CAUTION: Open and close bonnets with the rams fully retracted (Open position). Never apply operator closing pressure to open a bonnet with all bonnet bolts unscrewed. Otherwise, the ram will bind in the ram compartment and damage the BOP. 3. Cycle the rams Open and Closed three times, using 200 PSI (14 Bar) operator pressure. Observe for proper operation and hydraulic leaks. Record results on inspection form. Leave the rams in the Open position. If a visible leak occurs: a. Stop the test. b. Vent pressure from the BOP.

7.1 General A. Purpose The procedures in this section cover the wellbore pressure test of the Hydril ram BOP. This test verifies the ability of the ram BOP to seal against wellbore pressure. B. Inspection Records During the wellbore pressure test of the ram BOP, records should be kept of the results. Use the Ram BOP Inspection Form located in Section 9. C. Control System Requirements The Hydril ram BOP may be tested with any oil field

test pump of sufficient pressure capacity. A 3-position 4-Way valve (Open, Block, Close) and a hydraulic regulator should be installed in the output line of the test pump. An opening and closing line is required to operate each set of rams. These control lines are connected to the one-inch NPT ports on the hinge side of the BOP. Any clean, light petroleum hydraulic oil can serve as a hydraulic fluid. Fresh water may be used if water soluble oil is added. Antifreeze must be added to water based operating fluids to prevent serious damage to the operators when used in freezing conditions. CAUTION: Do not use synthetic fluids or fuel oils. Serious seal damage will result.

7.2 Wellbore Pressure Test Procedure A. Testing Precautions Take the following precautions to insure the safety of all personnel during blowout preventer testing. 1. Use safety barrier during test operations. 2. Verify that test stump, blind flanges, mandrels, blind hubs, piping, valves, gauges, and related equipment are rated for the test pressures. 3. Check resolution and accuracy of pressure indicating devices. A resolution of one percent of full range and an accuracy of two percent is required. 4. Do the following if a leak occurs of unacceptable pressure loss occurs: a. Stop the test. b. Vent pressure from the BOP.


Make necessary repairs. If repairs require disassembly of the BOP, perform the Wellbore Pressure Test again.

B. Tools and Materials required: 1. One new API metal ring gaskets 2. Light machine oil ( Gulf Harmony No. 46 or Exxon Coray 100) 3. Never-Seez thread lubricant (.069 coefficient of friction) or equivalent 4. Ram BOP Inspection Form (refer to Section 9) C. Wellbore Pressure Test 1. If the ram BOP is already installed on the test stump, continue to Step 2. Otherwise, install the BOP onto the test stump as follows: a. Wipe hubs/flanges, ring gasket, and ring grooves clean with a rag soaked in light machine oil. b. Install the BOP onto the test stump. Lift the BOP using the sling arrangement shown in Figure 7-1.

WARNING: THE RAM BOP IS VERY HEAVY AND BULKY EQUIPMENT. TAKE EXTREME CARE WHEN LIFTING IT. DO NOT PLACE HANDS OR OTHER BODY MEMBERS WHERE THEY CAN BE INJURED BY CONTACT WITH OTHER EQUIPMENT DURING LIFTING AND INSTALLATION OPERATIONS. BE SURE THAT THE LIFTING APPARATUS IS ADEQUATE TO HANDLE THE LOAD.

1) If a clamp is required to make up the connection between the test stump and the ram BOP, clean the clamp thoroughly and coat the insides with light machine oil. Apply Never-Seez thread lubricant to clamp nut and bolt threads. Tighten clamp nuts and bolts alternately, side to side, during installation to bring the clamp haves together uniformly. Strike the clamp occasionally with a sledge hammer during tightening to ensure proper seating of the clamp on the hub. Contact clamp manufacturer for torque values. 2) If studs and nuts are required to make up the connection between the test stump and the ram BOP, apply Never-Seez thread lubricant to the threads prior to installation. Refer to the BOP operator's manual for the torque value. Blind off all outlet connections with appropriate hardware. Outlet clamps (if required) are

installed in the same manner as end connection clamps. d. Connect test pump to the ram BOP. Refer to Paragraph 7.1.C. Open the ram BOP bonnets and cycle the rams using 200 PSI (14 Bar) pressure. Leave the rams in the Open (retract) position. Close the bonnets and tighten the bolts using 100 percent of the torque value shown in the BOP operator's manual. Also refer to the operator's manual for the tightening sequence. If pipe rams are installed in the ram BOP, install a test mandrel into the bore of the ram BOP. Do not install a test mandrel if shear rams are installed. Fill the bore of the ram BOP with clean tap water to a level six inches above the rams. Close the rams using 1500 PSI (103 Bar) for pipe rams or 3000 PSI (207 Bar) for shear rams. Vent the operator system to zero. Remove the excess water from above the rams

so that rams can be observed clearly. 9. Apply wellbore pressure of 200 - 300 PSI (14 - 21 Bar). Isolate (Block) test pump from ram BOP and allow pressure to stabilize. Hold pressure for three minutes minimum. Observe for dramatic pressure loss and leakage. Use a mirror or boroscope suspended over the bore of the BOP to observe for leakage between the ram packing and the mandrel.

WARNING: DO NOT EXTEND ANY PART OF BODY OVER THE BOP WHILE PRESSURE IS IN THE WELLBORE. This low pressure test is satisfactory if no visable leaks occur. Record initial and final wellbore pressure on the inspection form. If no leaks occur, continue to the next step. Do the following if a leak occurs: a. Stop the test. b. Vent pressure from the BOP.


Make necessary repairs. If repairs require disassembly of the BOP, perform the Wellbore Pressure Test again beginning with Step 2. 10. Increase wellbore pressure to BOP rated working pressure (refer to operator's manual for working pressure of your particular ram BOP). Isolate (Block) test pump from ram BOP and allow pressure to stabilize. Hold pressure for three minutes minimum. Observe for dramatic pressure loss and leakage. Use a mirror or boroscope suspended over the bore of the BOP to observe for leakage between the ram packing and the mandrel.

WARNING: DO NOT EXTEND ANY PART OF BODY OVER THE BOP WHILE PRESSURE IS IN THE WELLBORE. This high pressure test is satisfactory if the well pressure does not drop more than 100 PSI (7 Bar) in three minutes and no visable leaks occur. Record initial and final wellbore pressure on the inspection form. If pressure loss is less than 100 PSI (7 Bar) and no leaks occur, continue to the next step. Do the following if a leak occurs or if an unacceptable pressure loss occurs: a. Stop the test.

b. Vent pressure from the BOP.

Make necessary repairs. If repairs require disassembly of the BOP, perform the Wellbore Pressure Test again beginning with Step 2. Vent wellbore pressure to zero. Allow a few seconds to allow any residual pressure to bleed off. Open (retract) rams and remove mandrel. Drain water from wellbore. If further testing is required, leave the ram BOP installed on the test stump. If testing is complete, remove the BOP from the test stump as follows: a. Install the lifting apparatus onto the ram BOP Lift the BOP using the sling arrangement shown in Figure 7-1. 1) If a clamp is required to make up the connection between the test stump and the ram BOP, remove the clamp. 2) If studs and nuts are required to make up the connection between the test stump and the ram BOP, remove the studs and nuts. b. Remove blind hardware from outlet connections. Outlet clamps (if required) are removed in the same manner as the end connection clamp. c. Vent all pressure and disconnect the test pump from the ram BOP. d. Lift and remove the ram BOP from the test stump.

8.1 General A. Purpose The procedures in this section cover the MPL lock test of the Hydril ram BOP. This test verifies the operation of the multiple position lock. B. Inspection Records During the MPL lock test, records should be kept of the results. Use the Ram BOP Inspection Form located in Section 9. C. Control System Requirements The Hydril ram BOP may be tested with any oil field test pump of sufficient pressure capacity. A 3-position 4-Way valve (Open, Block, Close) and a hydraulic regulator should be installed in the output line of the

test pump. An opening and closing line is required to operate each set of rams. These control lines are connected to the one-inch NPT ports on the hinge side of the BOP. Any clean, light petroleum hydraulic oil can serve as a hydraulic fluid. Fresh water may be used if water soluble oil is added. Antifreeze must be added to water based operating fluids to prevent serious damage to the operators when used in freezing conditions. CAUTION: Do not use synthetic fluids or fuel oils. Serious seal damage will result. Closing time of the ram BOP is determined by the rate at which the hydraulic closing fluid can be delivered to the operating cylinders. Minimum closing time will result by short large-bore hydraulic control lines and large accumulator volume.

Make necessary repairs. If repairs require disassembly of the BOP, perform the MPL Lock Test again beginning with Step 2. Apply 200 PSI (14 Bar) wellbore pressure and hold for three minutes. NOTE: The application of higher wellbore pressures do not test the locking system because the ram blocks become well pressure energized; therefore, the locks become essentially passive. Vent wellbore pressure to zero. Apply 100 PSI (7 Bar) closing pressure to set the cylinder liner forward and away from the lockout segments. Disengage lockout devices by turning the stems 6 1/2 turns counterclockwise until they are fully retracted. Set normal operating pressure and open the rams. Vent the operating pressure to zero. If further testing is required, leave the ram BOP installed on the test stump. If testing is complete, remove the BOP from the test stump as follows: a.

Ram BOPs Inspection Forms

9.1 General A. Purpose The purpose of the inspection forms is to provide a written record of the findings when scheduled inspections of Hydril ram blowout preventers are performed. B. How To Use Forms The inspection forms in this section are intended to be used as a master for photocopying. The Ram BOP Inspection Form is written for a single ram BOP containing two bonnets and one ram compartment. For models that have more than one ram compartment, photocopy this form as many times as there are ram compartments in use. Each form is designed to be used as you follow the corresponding inspection procedure outlined in the various sections of this manual. The section and paragraph where the procedure is located is given on the form. The numbered steps on the form correspond to the numbered steps in the procedure. The Ram BOP Inspection Form incorporates all of the scheduled inspections listed in Table 2-1 of Section 2. However, not all of the inspections and tests are necessary for a given inspection interval. To use the form correctly, check the box at the top of the form to select the desired inspection interval; fill out the descriptive sections; perform the necessary inspections and tests listed in Table 2-1; and skip the inspections and tests that do not apply. The inspections and tests on the form that do not apply can be crossed out or marked as being not applicable. NOTE: The Pipe/Variable Ram Form and the Shear Ram Form are separate forms due to the requirement for unscheduled gauge inspection of the rams that often occurs. However, the forms are used as part of the Ram BOP Form during scheduled gauge inspection.
