Ship motions and unsteady pressures on ship hull in oblique waves estimated by potential-based solvers

Abstract The seakeeping performances in oblique wave conditions, such as ship motions and unsteady pressures on a hull, are getting more important, recently. These physical quantities used for estimating loads induced by waves evaluating the safety of ship. Thanks to evaluation various incident angles, rational design with sufficient less construction cost can be realized. Therefore, estimation numerical schemes those conditions is demanded design. However, were usually validated through comparison experimental data only heading because few towing tanks carry out experiment advancing waves. computed results should well before industrial usage schemes. Although Computational Fluid Dynamics useful know performance thanks development computer these years, it takes much longer time than based potential theory. For this reason, three solvers theory, Salvesen-Tuck-Faltinsen method, Green function Rankine panel comparing pressure hull obtained from tank tests conditions.
