Question 2775 Deck General

The correct answer is B) store fluid under pressure. A hydraulic accumulator aboard a MODU (Mobile Offshore Drilling Unit) is designed to store fluid under pressure. The accumulator acts as a reservoir, holding a supply of pressurized hydraulic fluid that can be quickly released into the system when needed, helping to maintain system pressure and providing a buffer against pressure fluctuations. The other answer choices are incorrect because: A) an overpressure relief valve, not an accumulator, is designed to provide overpressure relief; C) an accumulator does not replenish fluid to a system, it stores the fluid under pressure; and D) an accumulator is not the same as a fluid reservoir, which simply holds unpressurized fluid.
