Question 1767 Deck Safety

70% to pass

You are on the SS American Mariner and involved in a collision. Your draft has increased uniformly and there is about 4 feet of freeboard remaining. The vessel is on an even keel and has a long rolling period. The roll is sluggish, and the vessel hangs at the ends of a roll. Which of the following actions would you take First to correct the situation?

A Flood any empty double bottom tanks to decrease KG.
B Pump out a slack double bottom tank to reduce free surface.
C Jettison topside weights to increase freeboard.
D Pump out flooding water in the cargo holds to reduce free surface.
AI Explanation

The correct answer is D) Pump out flooding water in the cargo holds to reduce free surface. The key factors here are the increased draft, decreased freeboard, and sluggish rolling period, which indicate a vessel in a potentially unstable condition. In this scenario, the priority should be to reduce the free surface effect caused by any flooding in the cargo holds, as this can significantly impact the vessel's stability. Reducing the free surface will help restore the vessel's stability and rolling period. The other options, while potentially useful in other situations, do not directly address the immediate stability concerns caused by the flooding.
