Question 4621 Deck General

The correct answer is B) counterflood in 1P. When a vessel suffers major damage resulting in flooding, the primary goal is to maintain the vessel's stability and prevent further loss of buoyancy. In this case, with flooding in tank C3S, counterflooding in tank 1P is the best countermeasure. Counterflooding involves intentionally flooding an undamaged compartment or tank to offset the effects of the original flooding, thereby maintaining the vessel's stability. By counterflooding in 1P, the weight distribution and trim of the vessel can be adjusted to counteract the effects of the flooding in C3S, which is the most effective way to address the situation. The other options, such as pumping from the damaged tank C3S or counterflooding in 10S, would not be as effective in maintaining the vessel's stability and preventing further loss of buoyancy.
