Question 3206 Deck General

The correct answer is D) starboard ballast pump and the crossover system. If the port ballast pumps fail, the starboard ballast pump and the crossover system can be used to deballast from tank 1P. The crossover system allows transferring ballast between port and starboard tanks, enabling the use of the starboard ballast pump to deballast the port tank. This is a common approach when one set of ballast pumps becomes inoperative. The other options are incorrect because the port drill water pump, port bilge pumps, and port saltwater service pump are not designed or intended for deballasting operations. They serve different functions on the vessel and cannot effectively replace the ballast pump system.
