Cameron U type Ram BOP

The Cameron U BOP blowout preventers are the most widely used ram-type BOP for land, platform (platform rigs) and subsea applications worldwide and offers the widest range of sizes of any Cameron ram-type BOP.

• Hydraulic stud tensioning is available on larger sizes to ensure that stud loading is consistently accurate and even.
• A bonnet seal carrier is available to eliminate the need for high makeup torque on bonnet studs and nuts.
• Hydraulically operated locking mechanisms, wedge locks, lock the ram hydraulically and hold the ram mechanically closed even when actuating pressure is released. The operating system can be interlocked using sequence caps to ensure the wedge lock is retracted before applying pressure to open the BOP.
• For subsea applications, a pressure balance chamber with wedge locks eliminates the possibility of the wedge lock becoming unlocked due to hydrostatic pressure.
• Other features include hydraulically opening bonnets, forged body and a wide selection of rams to meet all applications.

Cameron pipe rams are available for use in Cameron ram-type BOPs to fit all commonly used sizes of tubing, drill pipe, drill collar or casing pipe.

• 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 Cameron pipe rams (except U BOPs larger than 13 3/4″)
