I. FEATURES AND BENEFITS
The CAMERON U Blowout Preventer is the most widely used ram-type BOP for land and platform applications worldwide and offers the widest range of sizes of any CAMERON ramtype BOP. Like other CAMERON preventers, the rams in the U BOP are pressure energized; wellbore pressure acts on the ram to increase the sealing force and to maintain the seal in the event of hydraulic pressure loss. Seal integrity is actually improved by increased wellbore pressure.
Other features of U BOP: • Available in a wide variety of sizes, working pressure, body configurations, end connections and side outlets, and with rams to suit a large amount of requirements. • Side outlets up to 4-1/16 (for 7-1/16 to t o 26-3/4 BOPs) can be provided. Side outlets can be studded, flange or hub. • Flanges conform to API standard 6A. Hubs conform to API 16A. • Hydraulic bonnet open/close provides quick ram change-out. • Metal-reinforced bonnet seal to ensure a tight seal and resist extrusion is standard. • Bonnet seal carrier is available to eliminate the need for high make-up torque on the bonnet bolts. • Manually or hydraulically operated locking system. • Large bore shear bonnets and tandem boosters are available for applications requiring increased shear force. • A wide selection of rams to meet m eet all applications. • Manufactured to comply with NACE MR-01-75 requirements. • Can be monogrammed to API 16A.

VII. HYDRAULIC CONTROL SYSTEM (REF. EB 798D) 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 from 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 t he 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 bonnets closed. For more information about pressure requirements and operating fluids see EB-196D. Quantities of hydraulic fluid needed and sequences are ar e given in following table and sketches.
For all sizes/pressures U BOP, the operating ports sizes (Open and Close) are 1”-11-1/2 NPT.

IX. SEALING TECHNOLOGY A. Bonnet Seal and Connecting Rod Seal Standard U BOPs are supplied with bonnet seal - a metal-reinforced elastomeric seal gasket which seals between the t he body and intermediate flange and connecting rod seal (a lip seal made from oil resistant nitrile). When high temperature and/or high concentrations of H2S are expected, CAMERON recommends the use of CAMLAST bonnet and connecting rod seals along with CAMRAM 350 packers and top seals.

B. Bonnet Seal Carrier The bonnet seal carrier is a bore-type sealing assembly which replaces the face seal used as the previous bonnet seal. The standard bonnet seal can be replaced by an optional seal carrier; thanks to this option, 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 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. To set up seal carrier on existing equipment, additional machining is required on body and intermediate flange. Seals used on seal carrier are made from CAMLAST material good for high temperature and/or high concentration of H2S.

D. Sealing Improvements In order to improve reliability and durability of our sealing parts, O-ring items 30 and 33 of piston ram change have been replaced by four lobes rings. O-Rings historically used on ram change pistons are subjected to high speed linear motion, and under poor lubricated conditions may roll. O-Rings have been replaced by quad rings giving more stability and less purposed to twist. Both seals are using exactly same groove and are perfectly interchangeable.

E. Emergency Backup In case of the primary con-rod seal leaks (leak detected at the vent port on lower side of intermediate flange), a secondary seal can be energized by injection of plastic packing through the injection port
on upper side of the intermediate flange. To energize the secondary seal of connecting rod: 1. Remove with care plug (17) and plastic packing screw (16). Be careful as small amount of fluid under pressure may have migrated through the seal and the check valve and may be trapped underneath the plugs. 2. Check if stick of plastic packing is already in injection hole. If not, Figure 29: Plastic Packing Components Injection

B. Hydraulic Lock 1. Wedgelock Features and Benefits The U BOP wedgelock is a hydraulically locking mechanism. It locks the ram hydraulically and holds the ram mechanically closed even when actuating pressure press ure is released. The operating system can be interlocked using sequence valve to ensure that the wedgelock is retracted before pressure is applied to open the BOP.
The existing wedgelocks are originally designed for operations with pipe/blind/shear rams. Utilization of wedgelock with Variable Bore Ram (VBR) and flexpacker ram has limitation (see EB-896D).

With unlock sequencing valve: When an unlock sequencing valve is used, it’s installed instead of lock cap. In this case, the wedgelock unlock chamber is connected with the bonnet open chamber through the sequencing valve. Sequencing valve function is to secure opening operation only when full unlock position is achieved. To ensure a correct functionality, a plug must be installed at the end of the open piston ram change (each bonnet) and also on body open port. For information about piping with sequencing valve, refer to SK-120115-01.

2. Inserted Packer Rams The Cameron inserted packer for stripping/snubbing service is designed with a field replaceable, wear-resistant, non-rotating insert block. The insert block is fabricated from a specially formulated ultra-high molecular weight polyethylene (UHHMWPE) which extends service life. The insert block is designed to be self-locking in the packer and should not require screws or other fasteners to hold it in place. The Cameron design eliminates the major causes of failure for inserted packers using semicircular inserts held in place with screws, including rapid insert wear out and inserts rotation resulting in permanent packer damage.

B. VBR Rams 1. VBR Ram Details The Variable Bore Ram (VBR) enables a standard U BOP to seal on several different pipe diameters. VBR are available on several sizes ranges. All rams listed are suitable for H2S service per NACE MR-01-75. The VBR seals on a range of drill pipe sizes as well of as extrusion hexagonal kellys and provides uniform sealing pressure with virtual elimination paths. The mechanism of closure of the VBR packer is similar to standard pipe ram packers. The packers extend forward of the ram body faces when the rams are closed, the packers contact each other on the leading surfaces at the sides thecontinues pipe bore. As theofram to close, the rubber in the packers is displaced inward to close the packers around the pipe.

C. Flexpacker Rams 1. Standard Flexpacker Rams The Flexpacker is a multi-bore sealing device that uses radially moving, stacked antiextrusion segments to retain wellbore pressure. Each layer of segment is machined to fit a specific pipe size within the sealing range, while the packer top plate is cut to matchinto thethe diameter the largest pipe size. As to different sizes of pipe are introduced sealingof bore, the segments s egments align fit closely around the pipe and reduce the extrusion gap to a minimum. Cameron flex rams included the following features: • The flexpacker requires little little or no break-in and will seal on the first closure closure under typical operating conditions. • The anti-extrusion segments are positively retained in the packer by means of pins running vertically through the segments. • Guidance and alignments of pipe pipe into the sealing bore is aided by chamfers on the leading corners of the anti-extrusion segments.

2. NR (Narrow Range) Flexpacker Rams The NR Flexpacker is a narrow range VBR packer designed for use with tapered drill strings. The Flexpacker NR fits standard fixed bore CAMERON rams. The Flexpacker NR seals around a range r ange of specified pipe sizes to provide economical sealing capabilities at a fraction of the cost of traditional range packers. The patent Flexpacker NR design features metal inserts bonded into the elastomer which move radially as BOP rams close. As the ram energizes, the set of metal inserts matching the size of pipe in the bore is forced against the pipe. This design virtually eliminates elastomer extrusion and ensures uniform distribution of pressure around the pipe. Maximum service life is achieved at the extremes of the specified size range for this ram packer. The NR Flexpacker is available to fit standard pipe rams for U BOPs (Ref. EB859D).

2. Shearing Blind Rams (SBR) Standard SBRs are “single piece” shear rams with the blades integral to the ram body. The upper SBR features a ‘V’ shaped cutting edge while the lower SBR as a straight cutting edge. The upper SBR houses a large blade packer which seals on the front surface of the lower SBR blade. Under normal operating conditions, SBRs are used as blind rams. The large front packer in the upper shear ram seals against the front face of the lower shear ram, resulting in prolonged packer life similar to that of standard blind packers. Features of SBRs include: • Large frontal area on the blade face seal that reduces pressure on the rubber and increases service life; • CAMRAM™ top seals that are standard for all U SBRs; and • Cameron SBR’s, both inserted and and integral blades, that meet the H2S requirements of both API 16A and NACE MR-01-75. Sulfide stress cracking susceptible materials are used for the blades; however, the main bodies of the SBRs are made of sulfide stress cracking resistant materials. Shearing action: Upon completion of shearing, the lower fish is folded over and flattened to allow the front surface of the lower blade to seal against a blade packer. a. SBR Body Type I

3. H2S Shearing Blind Rams (SBR) H2S SBRs are similar in design to the standard SBRs type I with the exception of the shear blades. H2S SBRs feature blade inserts of hardened high allow material suitable for H2S service. Cameron H2S SBRs are fully compliant with NACE MR-01-75 and API 16A. Therefore, they are acceptable for use in severe H2S environments. In addition, they have a long and successfully history of performance perf ormance in oil well drilling.

4. Double Shear Rams (DS) DS shear rams were developed to shear multiple tubing strings regardless of their orientation to the centerline of the ram bore. In addition to this capability, the DS shear rams can shear larger diameter tubular than the standard SBRs due to the increased blade width and thickness. Efficient shear blade geometry on both the upper and lower rams serves to reduce the required shearing force. The DS shear rams include the same features than shearing blind ram but they can shear heavier, larger pipe and are better suited for shearing multiple strings compare to the SBR for three main reasons: • The blades are wider, covering more of the through through bore; • The fold-over shoulder shoulder has been eliminated eliminated by placing placing the blade seal between the blades; and • Both blades blades have an efficient ‘V’ shape. While these features increase shearing capability, they reduce performance of the DS as a blind ram. The wider blade dictates narrower side packers, and the seal between the blades cannot be energized directly by ram closure. This must be accomplished by feeding rubber from the side packers into the blade seal slot. This means that the sealing system of the DS is less robust than one SBR and the packer service life is shorter. Shearing action: Upon completion of shearing, the lower fish is housed in a vertical pocket while the blade face seal provides a seal between the horizontal faces of the upper and lower blades.

5. Double Shear Interlocking Rams (DSI) DSI Shear Rams are similar in design to the standard DS shear rams except for the interlocking feature of the rams. Pockets in the lower ram and arms on the upper are used to prevent any vertical separation between the lower and upper blades. The interlocking feature provides the capability to shear wireline and braided cable with zero tension in the line and still maintain a seal. In doing this, some of the blade width is lost, thus losing the ability to shear larger diameter pipe and casing. Shearing action: Same as the DS rams except that when the rams first engage, any separation between the blades is eliminated.

6. Interlocking Shear Rams (ISR) The interlocking shear ram (ISR) is available for the U BOP. The ISR rams provide an improved shearing capacity alternative to the standard SBR rams. Since the geometry of the ISR ram incorporates a “V” shape and is designed as wide as possible, it can shear multiple strings and drill pipe as large as 6-5/8” OD. Also, ISR rams do not have to fold over the lower fish. This mean less force is required to shear and, by leaving the fish open, kill mud can be pumped down the severed drill strings. The interlocking mechanism incorporated in the ISR means these rams can be used in an oversized cavity without fear of a leak at low wellbore pressure.

7. Double ‘V’ Shear Rams (DVS) DVS Rams combine the features of the SBR and DS rams into one shear ram. Both the upper and lower DVS rams feature are ‘V’ shaped cutting edge to reduce the required shear force. The blade widths are maximized to increase the shearing capabilities. The upper DVS houses a large blade packer which seals on the front edge of the lower DVS blade. Shearing action: upon completion of shearing, the lower fish is folded over and flattened to allow the leading edge of the lower blade to seal against a blade packer.

4. Recommended hydraulic fluid (Ref. EB 196D and EB 928D): Light hydraulic oil is the recommended operating fluid for U BOPs used in land drilling operations. Any type is satisfactory except fuel oil, which causes rubber seals to swell and deteriorate. In marine operations, a water and lubricant mixture is recommended. Water can be used in land operations, provided lubricant is added to prevent corrosion and provide lubrication, and antifreeze is added when necessary. Should an emergency require the use of corrosive or contaminated fluid to operate a BOP, the BOP should be torn down, thoroughly cleaned, and all seals should be carefully checked for excessive wear or corrosion as soon as is practical thereafter. The control unit pump suction should have a strainer to keep sediment out of the operating system, and the control contr ol unit reservoir should be flushed and cleaned periodically. 5.

DRILLING SYSTEMS
For bonnet installation on body, lift bonnet subassembly levelled using operating piston (in retracted position) and bonnet cap ram changes (Ref. EB 932D).
Figure 75: Levelled Bonnet for Installation
BOP assembly can be lifted by passing sling under bonnets (slings positioned as closed as possible from body). As an alternative, threaded holes on top of body can be used. Before use of these holes, threads should be checked for corrosion or damages. Lifting eyes and slings used should s hould be selected to handle the BOP weight given in section II.

DRILLING SYSTEMS
8. Hydraulic operating system requirements: The rated continuous working pressure for the U BOP operating system is 1500 psi (100 bars). Pressures of 300 to 500 psi (20 to 40 bars) normally provide satisfactory operation. Pressures in excess of 1500 psi may be required in high pressure BOPs to close the rams against high well pressures or shear heavy pipes. For optimum seal life, the applied hydraulic pressure should be limited to 1500 psi, especially when open pressure is required r equired to be held continuously. Accumulator units should be fitted with a pressure regulator to control the pressure applied to a BOP. Refer to section VII for fluid volume requirements. The maximum hydraulic operating pressure limit is 3000 psi (207 bars) to operate rams. B. Disassembly Procedure The work area should s hould be clean and well-lit. BOP DISASSEMBLY 1.)

DRILLING SYSTEMS
2.)
Install O-rings (24) in the two grooves on the exterior of the operating cylinder (6). Insert the operating cylinder (6) small diameter first into the center bore of the bonnet (3). Gently push until each one is seated. Use a soft-face hammer, if necessary, to seat the cylinder in the bonnet.
Large bore bonnets do not have separate operating cylinders. O-ring (item 24) will be installed on intermediate flange. 3.)
Install O-rings (31 and 32) on the ram change cylinders (11). Insert the ram change cylinders (11) into the bonnet (3), starting with the end opposite the O-ring. Gently push until each one is seated. Use a soft-face hammer, if necessary, to seat the cylinder in the bonnet.
Keep hands away from the ram change cylinders while they are being inserted into the bonnet. The cylinder will seat against the shoulder of the counter-bore in the bonnet. 4.)
Install the four lobes rings (33) and wear band (2R) on the ram change piston heads (9 and 10). Insert the ram change pistons (9 and 10) head first into the ram change cylinders (11). Carefully note position (right or left) of the open ram change piston (9) in the bonnet. The second bonnet assembly for the same ram bore cavity must have the open ram change piston (9) on the opposite side.
A bonnet with the open ram change piston piston (9) on the right-hand side of the bonnet assembly (when facing the intermediate flange side) will be considered the righthand bonnet and the other will be the left-hand. 5.)
Install the wear ring (42) and the lip seal (26) on the operating piston (5) with the lip of the seal facing the connecting rod end. Insert the operating piston (5) into the assembled ass embled bonnet (3) and operating cylinder (6) with the t he connecting rod end of the operating piston (5) facing up.
6.)
Place the intermediate flange (2) on the assembly table with the edge containing single tapped hole in upright position and the oval groove toward assembly man. Install four lobe rings (30) in ram change piston rod bores. Install wear ring (76) in corresponding groove (only for 13-5/8 15K, 16-3/4’’ 5 and 10K, 18-3/4 10K, 21-1/4 5K and 26-3/4 3K). Install O-ring (25) in operating piston rod bore. Install plastic packing ring (18) and energizing ring (19) in
operating piston rod bore.

Install connecting rod lip seal (20) in operating piston rod bore with lips facing away from intermediate flange. Install lip seal retainer (40) and retaining ring (41).
Install ram change seal assembly tools on end of the ram change pistons to prevent damage of threads and seals (see section XII F). 8.)
Using the two lifting holes on each side of intermediate flange, turn the intermediate flange (2) over with the oval bonnet seal groove upward. With a nylon strap or other suitable device, lift the intermediate flange (2) and position it over the bonnet assembly. ass embly. The plastic packing hole with the 1” NPT thread in the intermediate flange (2) must be on the same side as the 1-1/8-8 UN threaded hole on the bonnet (3). Carefully lower the intermediate flange (2) over the connecting rod end of the operating piston (5). Continue lowering the intermediate flange over the ram change pistons (9 and 10). See that the operating cylinder (6) and the ram change cylinders (11) have started to enter the bores prepared for them in the intermediate flange (2).
9.)
Before installing the cap screws (35), which secure the bonnet of the intermediate flange, lubricate the threads and the bearing surface under the head of each screw. Install cap screws (35) through the intermediate flange (2) and tighten per recommended bolt torque of API 6A Annex D. Torque is dependent on bolt diameter, stud s tud material, yield strength, and grease friction coefficient (f). Values given are for 0.07 friction coefficient obtained with MOLYKOTE GN plus grease. For other moly greases, consider +35% on torque value. (See following table for details)

While installing rams, inspect the ram bore and bonnet. • Inspect the vertical bore bore for key seating. • Inspect intersection between between vertical bore bore and ram bore. Grind out any raised metal surfaces. Do not remove any metal below original surface.
For acceptance criteria, refer to EB 905D.
I. Maintenance Procedure ROUTINE MAINTENANCE 1.)
If more than 500 psi (35 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.
To avoid damage to the packers, close pipe and VBRS only when pipe is in preventer. 2.)
Pressure test and operate the preventer once a week per API S53 Periodic Field Testing, or appropriate regulatory agency requirement.
PERIODIC MAINTENANCE (REF. EB 902D) 1.)
At 30 months or 800 operating cycles, whichever comes first, completely disassemble preventer for periodic inspection (refer to EB 902D). • Clean all parts. Do not not use a wire brush on on sealing areas. • Once a year, replace all rubber seals, gaskets and O-rings. • Replace ram packing according according to its physical condition. • Repair or replace damaged damaged metal parts. parts.

DRILLING SYSTEMS
Replacement parts should be obtained from Cameron (or authorized agent) and repairs should be performed by Cameron or Cameron authorized repair center, or under Cameron supervision. The annual inspection does not apply to rams, ram packers, and bonnet seals. These parts should be be inspected more often, often, for example, at each ram or packer change, or between wells. 2.)
In some cases, BOPs should be overhauled more often than once a year in cases when the BOP has been used in a severe operating environment or has been subject to misuse, or when the operating history of the unit is not known. Some examples are: • Prolonged or repeated use at high or low temperatures; • When operating system pressure is in excess of 3300 psi; • When used with chemically chemically aggressive well fluids; fluids; • If stored without proper preparation; or • If exposed to very high high flow rates, such as in a blowout.
It is not possible to prepare an exhaustive list of severe conditions. If there is doubt as to whether a particular condition has been severe enough to justify an overhaul, then a Cameron representative should be consulted, or the overhaul should be performed as a precaution. t o a Cameron facility for thorough examination 3.) The BOP should be returned to and testing if it has been exposed to any of the following conditions: • fire • temperatures above 600° F • pressure higher higher than rated working working pressure
The recommendation for an annual overhaul does not apply to BOPs in storage if they have been prepared and stored properly. properly. 4.)
Reassemble the preventer.
5.)
After reassembling the preventer, test the rams and operating system per Section XIV-J.
Hydrostatic proofng testing, which ishave onlybeen required when pressure containi containing components welded or heat treated, should only be performed in a Cameron or

M. Storage PREVENTER • Condition of Storage: Medium term: BOP is not to be put into service for a period less than three months. Long term: BOP is not to be put into service for a period of three months or longer. • Periodic Testing of Preservation Fluid (long-term only): only): Preservation fluid should be tested at 3- to 6-month intervals. Fluid may be changed every 12 months if necessary. • Planned Maintenance: At 3- to 6-month intervals, inter vals, the BOP bonnets should be opened and the t he cavity visually inspected (in case of long-term storage). 1. Open the bonnets and remove the ram subassemblies. 2. Remove the top seals and packers, then wash the ram subassemblies. 3. Lubricate the ram bodies with heavy grease.
DO NOT lubricate the top seals or packers. 4. Do not store the ram subassemblies inside the preventer.
Rubber products that have into service and are subsequently stored willbeen haveput an unpredictable shelf-life. This is attributable to to their varied physical 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 papers. 9. Lubricate the ram bore with heavy grease.
10. Lubricate the end and outlet connection faces with heavy grease and cover them with flange protectors. 11. Flush the operating system using us ing clean operating fluid. TC1403

For Medium-Term Storage 12. Hydraulic chambers should be partially filled with a corrosion corr osion protection fluid containing a vapor phase inhibitor. 13. The operating piston should be moved in open position. 14. Install the 1” NPT pipe plugs into the OPEN and CLOSE connections. Tag the t he assembly with a brass tag and mark date and storage fluid used. For Long-Term Storage 1. Install 1“ NPT ball valves to the open and close ports. 2. Flush the operating system using us ing clean operating fluid. 3. Fill the operating system with preservation fluid containing a vapor phase inhibitor. 4. The operating piston should be moved in open position. 5. Close the ball valves and disconnect the hydraulic hoses. Tag the assembly with a brass tag and mark date and storage fluid used. 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 (4.4° C to 26.7° C). b. Rubber goods should be 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, s unlight, 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 that may generate ozone, such as mercury vapor lamps, high-voltage electrical equipment, electric motors, or any electrical apparatus that produces arcing. 4. Keep rubber products clean and free of solvents, oil, greases, or any other semisolid 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 • sulphur
• copper napthenate • other rubber goods of different rubber compounds compounds TC1403

5. When necessary, rubber goods may be cleaned with soap and water or methyl alcohol. After cleaning, the rubber goods should be dried at room temperature. 6. Examine the part before installation.
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 magnifying glass to ensure that there are no cracks. c. Replace items that show any aging signs mentioned above.
