Abstract

The far-field method for calculation of the wave drift force is implemented in the high order finitedifferenceseakeeping solver. The implementation is based on the Maruo formulation which employesthe Kochin function to obtain the complex amplitude of the velocity potential in the far-field. Theresults are shown both for zero and forward speed for the floating hemisphere and two ship geometries.Comparisons with WAMIT and near-field calculations are also presented.
