【Abstract】 This paper proposes a viscosity-equivalent reduced-order method(VEROM) for floating wind turbines to balance accuracy and computational speed in numerical simulations. Using the DeepCwind semi-submersible platform as the study object, a viscous flow model for platform motion calculation is established and validated against wave tank test results. A forced motion-based approach is introduced to obtain the platform damping characteristics, which are computed under various motion amplitudes and periods. Finally, the effectiveness of the VEROM model is verified through free decay tests and regular wave conditions.更多还原
