Abstract:
A set of procedures to evaluate the time series of the diffraction forces on a moored ship inside
a harbor basin is presented. Nonlinear wave propagation is obtained using a Boussinesq finite
element numerical model, BOUSS-WMH. Determination of hydrodynamic forces acting on the
ship is achieved using a modified version of the WAMIT model. Finally, time series of the wave
forces on the ship and of the inherent moored ship motions are obtained using BAS numerical
model. The main focuses of this work are: the coupling of these three models and the
modification of the method used in WAMIT to determine diffraction forces. Some simple and
practical applications of this procedure are presented as well.
