Question 4640 Deck General

The correct answer is A) 9S. When a vessel suffers damage to its hull below the waterline, the goal is to pump water from tanks that will help maintain the vessel's stability and prevent further flooding. In the case of the DEEP DRILLER with damage to the starboard aft column, pumping from tank 9S (the starboard aft tank) would help counter the flooding and keep the vessel stable. The other answer choices are incorrect because pumping from tanks 2S, 2P, or C1S would not provide the necessary counter-flooding to maintain the vessel's stability in this specific damage scenario.
