Question 4615 Deck General

70% 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. Pumping from tanks 2S and 9S is not sufficient to prevent increasing starboard list. You should consider counterflooding in tank _______________.

A C2BP
B 9P
C C2BS
D 2P
AI Explanation

The correct answer is A) C2BP. The reasoning is that when a vessel suffers damage and has a developing list, the standard procedure is to counterfloat the opposite side to help balance the vessel. In this case, since the damage is on the starboard side and the list is increasing, the vessel should counterfloat the port side to help counteract the list. The tank C2BP is located on the port side, so flooding this tank would be the appropriate action to take. The other options are incorrect because 9P is on the starboard side and would not help counteract the list, 2P is on the port side but is not the most appropriate tank to use for counterflooding, and C2BS is on the starboard side and would exacerbate the list.
