A time-domain hybrid method developed by authors is applied to estimate hydrodynamic forces, motions of ships advancing in waves. The fluid domain around a ship is decomposed into two fields, and the Rankine panel method and the Green function method are applied in each field. Combining both solutions on the artificial surface makes it possible to satisfy the radiation condition exactly and to take the nonlinearities of ship motions into account. In this paper, we apply the method to simulate ship motions in regular waves. The computed results are compared with experimental results and another numerical results by the other theories. Through the comparison, it is confirmed that the present method can estimate hydrodynamic forces, ship motions with high accuracy for any cases.
