  1. The calculated drafts covers the whole possible ship draft in the large amplitude motion ; secondly, the research creates and solves the ship large amplitude motion equations. on the one hand, the actual calculation takes into account the coupling between the different motion modes, on the other hand, in the process of calculation of the ship hydrodynamic coefficient, it considers the influence of the nonlinear factor. the hydrodynamic coefficient used in the calculation of froude - krylov force, diffraction force and radiation force changes instantaneously following the draft, and the hydrostatic buoyancy is computed very accurately for the instantaneous immerse hull
