    摘要： A blowout preventer (BOP) includes a pressure driven operator that is equipped with a balancing circuit to offset pressure inside the BOP. The operator, which is used to drive a ram, includes a piston, coupled to the ram by an operator arm, and a balance arm on a side of the piston opposite the operator arm. Pressure from inside the BOP communicates to an end of the balance arm opposite the piston and exerts a force to drive the ram radially inward.

    摘要： A BOP system for use in a high pressure subsea environment, including a BOP stack including a lower marine riser package and a lower stack portion, the lower stack portion having a plurality of BOP rams attached to a subsea wellhead. The system also includes a riser subsystem extending from a drilling vessel to the BOP stack and providing fluid communication therebetween, a ship board subsystem electronically, mechanically, and hydraulically connected to the BOP stack and the riser subsystem to control the functions of the BOP stack and the riser subsystem, and a safety instrumented system having a surface logic solver and at least one subsea logic solver, the safety instrumented system in communication with at least a portion of the BOP rams to act as a redundant control system in case of failure of the ship board subsystem.
