Abstract
To assess the ship structural strength, this paper is concerned with ship motions and sea loads by a 3D Rankin Panel Method. The method was used to solve linearized ship motions and sea loads for a ship with a steady forward speed in quasi-random incident waves. The solution algorithm involves the discretization of the ship hull and part of the free surface by panels, over which a B-spline approximation is used. The method is for the solution of the wave-body interactions in frequency domain and will be developed in time domain to solve the non-linear problem in the near future. The paper shows results for a Wigley hull and a large container ship with and without a forward speed. The hydrodynamic pressure exerted on the ship are found to be in remarkable agreement with related experimental measurements which were carried out by the China Classification Society and other referenced results demonstrate that the solution scheme is available for the 3D flow and sea loads.
