Ship roll motion with water inside compartments due to damage

The presence of water inside compartments (inside water) changes the attitude of a ship, its stability and motion characteristics. Roll motion experiments with inside water in a model in beam seas had been conducted and found that the motion characteristics were different from that of the model without inside water. In this paper, a method to simulate the roll motion of ships with inside water is described. Roll motion simulation is done for a ship, with and without water inside a deck compartment. The results of simulation are compared with the roll motion traces of similar model experiments.
