6 FAQs about [Blowout Preventer Control System Energy Accumulator]

What is a blowout preventer (BOP) accumulator bottle?

Blowout Preventer (BOP) hydraulic control systems have long used accumulator bottles to deliver energy to function equipment more quickly than the pumps can alone. With the advent of subsea stacks, people recognized the need to modify these accumulators and the operating procedures to reflect the effects of hydrostatic head.

How does a blowout preventer control system work?

Blowout preventer control systems, like other hydraulic systems, need a high quality fluid to perform their operations satisfactorily. The hydraulic fluid lubricates all the valves in the control system and acts as a corrosion inhibitor for subsea internal parts.

What is a bop accumulator?

An accumulator is a vessel that stores hydraulic pressure required to close the blowout preventer (B.O.P.) if a blowout occurs. The amount of pressure required varies depending on the type of B.O.P. A BOP accumulator unit (also known as a BOP closing unit) is one of the most critical components of blow out preventers.
