heal.abstract	A three-dimensional nonlinear time domain simulation method for solving the problem of a ship undergoing large-amplitude motions originally developed at Harbin Engineering University is introduced in this paper. In this method, the body boundary condition is satisfied on the instantaneous wetted surface of the moving ship, while the free-surface boundary condition is linearized. The transient free-surface Green function, which includes a Rankine part and a free-surface memory part, is employed to formulate the relevant boundary-value problem and its numerical solution is accomplished by the solution of integral equations for the strength of sources and the mixed source-dipole distribution on the wetted body surface. The main advantage of this method lies in its capability to investigate large-amplitude motions of bodies with forward speed, that is, various nonlinear effects of interest to ship's safety. Some of the preliminary results obtained by this approach, referring to the radiation and diffraction problems, at zero and non-zero speeds, are herein presented and compared with those from the frequency domain code of NTUA and with other published theoretical and experimental results and show a fully satisfactory agreement.	en
