Time-Domain Calculations of Drift Forces and Moments

摘要

In this thesis, we study the effect of the forward speed of a ship on the hydro-dynamic forces, in particular the drift forces. Previous studies, restricted to zero forward speed, were based on the assumption of harmonic waves, thus reducing the time-dependent equations. In this study, the actual time-dependent equations including forward speed, are solved, enabling to simulate non-harmonic waves.
