70% to pass

The DEEP DRILLER, loaded as shown in Sample Load Form #4 (Drilling), suffers major damage which results in flooding in tank C1P. Pumping from tanks in the vicinity of the damage has proven ineffective. Your best countermeasure is to _______________.

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

The correct answer is D) counterflood in 10S. When a vessel suffers major damage resulting in flooding, the proper response is to counterflood adjacent tanks to maintain stability and prevent the vessel from capsizing. In this case, with flooding in tank C1P, the best countermeasure is to counterflood the opposite, symmetrical tank 10S. This helps offset the free surface effect and re-establish the vessel's equilibrium. The other options, such as pumping from the damaged tank C1P or adjacent tanks, would not be as effective in restoring stability in this situation.
