Abstract
When a floater such as ships and offshore platforms is damaged on the sea, it is necessary to predict the motion of the floater and whether the floater is to sink or not. If the floater is to sink, the time to sink should be estimated. Until now, lots of related researches have been conducted to estimate the time through the flooding simulation. However, most of them are quasi-static methods and they did not consider ocean environmental loads such as waves, currents, and winds. Therefore, a dynamic method for the flooding simulation of the damaged floater considering ocean environmental loads is proposed in this study.
