Question 2820 Deck General

The correct answer is C) accumulator. The accumulator is the storage device that holds the nitrogen-pressurized hydraulic fluid used to close the blowout preventers. Accumulators store the pressurized fluid that is then released to rapidly close the blowout preventer when needed. The other options are incorrect because: A) an actuator is a device that converts energy into motion to close the blowout preventer, B) an annular preventer is a type of blowout preventer, and D) the annulus is the space between the casing and the drill pipe, not the storage device for the hydraulic fluid.
