Features

The Cameron U BOP blowout preventer is the most widely used ram-type BOP for land, platform

and subsea applications worldwide. Like all other Cameron preventers, the rams in the U BOP are

pressure-energized. Well bore pressure acts on the rams to increase the sealing force and maintain

the seal in case of hydraulic pressure loss. Seal integrity is actually improved by increased

well bore pressure.

Other features of the U BOP include:

• Bonnet seal carrier is available to eliminate the need for high makeup torque on bonnet bolts
• and nuts. The new 13-5/8” bodies have a bore seal. Therefore you can add the seal carrier
• without additional re-work. All other sizes require modification to accept the seal carrier.
• Manual or Hydraulic operating systems available.
• Hydraulically operated locking mechanisms, wedgelocks, lock the ram hydraulically and hold
• the rams mechanically closed even when actuating pressure is released. The operating system
• can be interlocked using sequence caps to ensure that the wedgelock is retracted before pressure
• is applied to open the BOP.
• For subsea applications, a pressure balance chamber is used with the wedgelocks to eliminate
• the possibility of the wedgelock becoming unlocked due to hydrostatic pressure.
• Retrofit to UM Bonnet is available to provide more shearing force without the need for shear
• bonnets, large bore bonnets, or tandem boosters.
• Other features include hydraulically opening bonnets, forged body and a wide selection of rams to
• meet all applications. See page 46-50 for rams available to fit the U BOP.
