Question 1583 Deck General

The correct answer is A) check valve. A check valve is typically installed on the discharge side of a cargo pump on a tank vessel. This is because a check valve allows flow in only one direction, preventing backflow and ensuring that the cargo is properly discharged from the tank. This is a safety requirement specified in the regulations governing the design and operation of tank vessels. The other options, such as a spectacle valve, globe valve, or butterfly valve, are not commonly used for this specific application on a tank vessel.
