Question 4762 Deck General

70% to pass

The DEEP DRILLER, loaded as shown in Sample Load Form #4 (Drilling), suffers major damage which results in flooding in tank C3S. Pumping from tanks in the vicinity of the damage have proven ineffective. Your best countermeasure is to _______________.

A pump from C3S
B pump from C1P
C counterflood in 1P
D counterflood in 10S
AI Explanation

The correct answer is C) counterflood in 1P. The reasoning is that when a vessel suffers major damage and flooding in one tank, the best countermeasure is to counterflood an adjacent, symmetrical tank on the opposite side of the vessel. This helps to maintain the vessel's transverse stability and prevent excessive heel or capsize. Pumping from the damaged tank (option A) or an adjacent tank (option B) would not address the stability issue. Counterflooding the 10S tank (option D) would not be the optimal choice, as it is not symmetrical to the damaged 3CS tank.
