The paper presents a procedure to obtain spatial mean slamming pressures suitable for design purposes of ships subject to slamming. The first step of this procedure consisted of using a linear seakeeping code to select equivalent design waves by systematically computing motions and relative velocities for different forward speeds and wave conditions that subject the ship to slamming loads. The selection of equivalent design waves was based on the magnitude of relative normal velocity between ship and wave. A nonlinear strip theory based seakeeping code yielded accurate predictions by simulating the motion behavior of the ships advancing in the selected design waves. Computed ship motions then served as part of the input for a RANSE1 code to predict slamming loads. The procedure was applied to two ships of modern design as well as to a generic design of a RoRo Ferry. Favorable agreement with experimental data from model tests validated the used methods. For one of the ships the influence of wave height, wave length and ship speed on slamming loads was investigated.
