Question 4771 Deck General

70% to pass

Failure of both port-side ballast pumps on the DEEP DRILLER prevents their use. To dewater from the port forward tanks, you should use the _______________.

A port drill water pump
B port saltwater service pump
C port bilge pumps
D starboard ballast pump and crossover system
AI Explanation

The correct answer is D) starboard ballast pump and crossover system. When the port-side ballast pumps fail, the starboard ballast pump and crossover system can be used to dewater the port forward tanks. This is because the crossover system allows transferring water between port and starboard tanks, enabling the starboard ballast pump to be used to dewater the port tanks. The other options are incorrect because: A) the port drill water pump is not designed for dewatering tanks, B) the port saltwater service pump is not the appropriate equipment for this task, and C) the port bilge pumps would not have the capacity to effectively dewater the forward tanks.
