Question 1779 Deck Safety

The correct answer is A) close any opening to the sea in an off-center tank. To prevent loss of stability from free communication flooding, you should close any openings to the sea in off-center tanks. This is because free communication flooding, where water can move freely between tanks, can cause a shift in the vessel's center of gravity and lead to a loss of stability. Closing the openings to the sea in off-center tanks helps to prevent this free communication flooding and maintain the vessel's stability. The other options are incorrect because: B) closing the cross-connection valve between off-center tanks does not address the issue of openings to the sea, C) completely flooding high center tanks would not prevent the loss of stability from free communication flooding in off-center tanks, and D) ballasting double bottom wing tanks would not directly address the issue of free communication flooding in off-center tanks.
