Question 4765 Deck General

70% to pass

While the DEEP DRILLER is loaded as shown in Sample Form #4 (Drilling), casing is accidentally dropped over the starboard side. Because the sounding level and starboard inclination are rapidly increasing, you decide that tank 1S is damaged. Your best countermeasure is to _______________.

A counterflood into 9P

B place a wooden plug into the vent of tank 2S

C dump the mud

D deballast from tank 2S

AI Explanation

The correct answer is D) deballast from tank 2S. The reason this is the correct answer is that if tank 1S is damaged, causing the sounding level and starboard inclination to rapidly increase, the best countermeasure is to deballast from tank 2S. This will help counteract the increasing list and reduce the risk of further stability issues. Counterflooding into 9P (option A) or placing a wooden plug into the vent of tank 2S (option B) would not directly address the increasing list caused by the damaged tank 1S. Dumping the mud (option C) would not be an appropriate response to the specific situation described.
