On the prediction method for ship motions of trimaran in oblique waves

The authors developed the prediction method for ship motions of trimaran in oblique waves. Present method is based on STF method, and is not considering hydrodynamic interaction between main hull and side hull. To validate the present method, the authors carried out tank test measuring ship motions of trimaran in oblique waves. Results show that the present method gives good agreement with experiments in the case of zero ship speed, and that it can capture ship motions in the case of non-zero ship speed qualitatively.
