Question 1301 Deck General

The correct answer is A) between the pump and discharge valve. A relief valve for a cargo pump is typically installed between the pump and the discharge valve to protect the pump from overpressure. This is in accordance with regulations and best practices for cargo handling systems on commercial vessels. The relief valve allows excess pressure to be released, preventing damage to the pump or other components. The other options are incorrect because: B) installing the relief valve between the pump and suction valve would not protect the pump from overpressure; C) installing it after the suction valve would not provide the necessary overpressure protection; and D) installing it after the discharge valve would not be an effective location to relieve excess pressure.
