Abstract
Securing the survivability under flooding condition is one of the most important subjects in ship design. For realizing rational and advanced assessment of damage stability, a numerical simulation method is developed for damaged ships by combining the moving particle semi-implicit method (MPS method) and the strip method based on potential flow theory. In this method, the flow field around the damaged part including damaged compartments is computed by the MPS method and that around the intact part is done by the strip method, separately. In order to validate the proposed method, model experiments are conducted for a damaged pure car and truck carrier. Then comparisons of the ship motion and the water flooding into the damaged compartment are conducted. As a result, it is confirmed that the proposed simulation method has good potential for the prediction of dynamic behaviours of damaged ships under flooding condition.
