Question 4671 Deck General
70% to passThe DEEP DRILLER, while loaded as shown in the Sample Load Form #4 (Drilling), suffers damage to the port aft column below the waterline. Pumping from tank 8P and 9P is not sufficient to prevent increasing port list and stern down trim. You should consider counterflooding in tank _______________.
A
1S
B
C2BS
C
1P
D
10S
AI Explanation
The correct answer is A) 1S. The reasoning is that in a situation where the vessel is listing to port and trimming down by the stern due to flooding in the port aft column, counterflooding tank 1S (the starboard forward tank) would help to counteract the port list and stern down trim. By flooding tank 1S, the vessel's stability and trim would be restored, preventing further loss of control. The other options are incorrect because: B) C2BS is not a tank on the vessel, C) 1P is the port forward tank which would exacerbate the port list, and D) 10S is the starboard aft tank which would not effectively counteract the stern down trim.
