Question 4609Deck General70% to pass
The DEEP DRILLER, while loaded as shown in the Sample Load Form #4 (Drilling), suffers damage to the starboard center column below the waterline. Among the tanks from which you should pump is tank _______________.
AI Explanation
The correct answer is D) 9S.
When the DEEP DRILLER suffers damage to the starboard center column below the waterline, the appropriate action is to pump from tank 9S (the starboard ballast tank). This is because pumping from this tank will help restore the vessel's stability and prevent further flooding or capsizing.
The other answer choices are incorrect because: A) 2P is the port fuel tank, which would not be used to address the damage; B) C1S is the starboard storage tank, which is also not the appropriate tank to pump from; and C) 9P is the port ballast tank, which would not be as effective in addressing the starboard-side damage.
