Question 4703Deck General70% to pass
The DEEP DRILLER, while loaded as shown in the Sample Load Form #4 (Drilling), suffers damage to the starboard aft column below the waterline. Pumping from tanks 8S and 9S is not sufficient to prevent increasing starboard list and stern down trim. You should consider counterflooding in tank _______________.
AI Explanation
The correct answer is D) 1P.
The reasoning is that when a vessel experiences damage resulting in a starboard list and stern down trim, the appropriate counterflooding measure is to flood the port side tank (1P) to counteract the starboard list and stern down trim. This helps maintain the vessel's stability and prevent further capsizing or sinking.
The other options are incorrect because: A) C2BP is not the appropriate tank to counter the starboard list and stern down trim, B) 10P may not be large enough to sufficiently counter the list and trim, and C) 1S would increase the starboard list rather than counter it.
