| Abstract: | Retardation functions and time-domain wave forces are solvedbased on three dimensional frequency-domain potential theory and impulse response function method, mooring forces are modeled by a quasi-static cable model, viscous damping coefficients are calculated through free-decay numerical simulation based on computational fluid dynamics method, so FOWT motion equation in wave in time-domain is established. The results of DeepCwind semisubmersible FOWT obtained by this method are in good agreement with the experimental data and other numerical simulations results, which prove the applicability of this method. |
