Question 4697Deck General70% to pass
The DEEP DRILLER, while loaded as shown in the Sample Load Form #4 (Drilling), suffers damage to the port forward column below the waterline. Pumping from tank 2P and 3P is not sufficient to prevent increasing port list and bow down trim. You should consider counterflooding in tank _______________.
AI Explanation
The correct answer is C) 10S.
When a vessel suffers damage resulting in a list or trim, the standard procedure is to use counterflooding to correct the stability issues. In this case, with the port forward column damaged below the waterline, the vessel is developing a port list and bow-down trim. To counteract this, the vessel should consider counterflooding tank 10S, which is the starboard aft tank. This will help to raise the bow and reduce the port list, restoring the vessel's stability.
The other options are incorrect because: A) 9S is the port aft tank, which would exacerbate the port list; B) 2S is the starboard forward tank, which would not effectively counter the bow-down trim; and D) C2BS is not a standard tank designation, so it is not the correct answer.
