Abstract

A floating offshore wind turbine (FOWT) is always subjected to the combined action of nonlinear waves and winds in the realistic operating conditions. It is important to explore the high-order hydrodynamic loads and the motion responses of the offshore floating wind turbine. Based on the nonlinear potential flow theory and the perturbative expansion technique, the time-domain higher-order boundary element method (HOBEM) is used to model the hydrodynamics of an offshore floating wind turbine in the present study. In addition, the Blade Element Momentum Theory (BEMT) is applied to the aerodynamics. The present methodology is verified by comparing with the FAST code. It is found that the nonlinear effect is significant. This study can provide a reference for the design of an offshore wind turbine system.
