| Research Abstract |
For the advanced damage stability assessment, a numerical simulation method for damaged ships was developed by combining the strip method and the MPS method which are used for the estimation of hydrodynamic forces on intact and damaged parts respectively. Through the comparisons with a model experiment using a damaged pure car and truck carrier, it is confirmed that the proposed method can predict the dynamic behaviours of damaged ships under flooding condition.
