Question 4773Deck General70% to pass
The DEEP DRILLER, while loaded as shown in the Sample Load Form #4 (Drilling), suffers damage to the port center column below the waterline. Pumping from tanks 2P and 9P is not sufficient to prevent increasing port list. You should consider counterflooding in tank _______________.
AI Explanation
The correct answer is B) C2BS.
The reasoning is that in a situation where the DEEP DRILLER has suffered damage to the port center column below the waterline, and pumping from tanks 2P and 9P is not sufficient to prevent an increasing port list, the appropriate action is to consider counterflooding in tank C2BS. This is because counterflooding the starboard wing tank C2BS will help to offset the port list caused by the damage, by adding weight to the starboard side of the vessel.
The other options are incorrect because they do not represent the appropriate tank to counter the port list. Counterflooding in tanks A) C2BP, C) 9S, or D) 2S would not effectively address the specific issue of the port list caused by the damage to the port center column.
