The paper presents a computational procedure to obtain ship motions in waves and spatial mean slamming pressures suitable for design purposes of ships subject to slamming. The first step consists 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 is based on the magnitude of relative normal velocity between ship and wave. Ship motions are computed using different methods and serve as part of the input for the RANSE code to predict slamming loads. A method of coupling the equations of motion to the RANSE (Reynolds-averaged Navier-Stokes) solver COMET is presented. Waves are generated in the computational domain.
