Question 1534 Deck General

The correct answer is C) suction side of the pump. The cargo pump relief valve is typically piped to the suction side of the pump to prevent overpressurization of the cargo system. When the pressure in the discharge line exceeds the set pressure of the relief valve, the valve will open and allow the cargo to recirculate back to the suction side of the pump, preventing damage to the system. Piping the relief valve to the suction side is the standard configuration as per industry regulations and best practices. The other options are incorrect because: A) the crossover line is not the correct location for the relief valve discharge; B) discharging to the atmosphere through a vent would not safely recirculate the cargo; and D) the pressure gauge is a separate component and not the intended destination for the relief valve discharge.
