Well Control - CAMERON U II Blowout Preventer
CAMERON U II Blowout Preventer

The Cameron U II BOP takes all of the features of the U blowout preventer and adapts them for subsea use in the 18-3/4-10,000 and 15,000 psi WP sizes.

Like all other Cameron preventers, the preventer rams in the U II BOP are pressure energized. Wellbore 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.
