A three-dimensional time-domain approach has been developed to compute large-amplitude motion response and the second-order added wave resistance for ships traveling in waves. The proposed method is an extension of a well established linear approach developed in a previous paper . The numerical model is developed based on boundary integral equation, which is solved at each time step by distributing desingularized sources above the calm water surface and employing constant-strength panels on body surface. The nonlinear Froude-Krylov and wave diffraction forces are computed. Equations of motion are solved with including the effects of Euler angles. A broad range of different hull forms, including two Wigley hulls, a Series 60 hull, and a S-175 hull, are employed to validate the present computational model. By comparing the obtained numerical results to experiments, it is demonstrated that the present model using double-body basis flow can well predict added wave resistance.
