Abstract

© Copyright 2016 by ASME.This paper aims to analyze the hydrodynamics of a floating offshore wind turbine (FOWT) in waves. Instead of modeling the incident random wave with the traditional wave spectrum and superposition theory, an impulse response function method was used to simulate the incident wave. The incident wave velocity was evaluated by a convolution of the wave elevation at the original point and the impulse response function in the domain. To check the validity of current wave simulation method, the calculated incident wave velocities were compared with analytical solutions; they showed good agreement. The developed method was then used for the hydrodynamic analysis of the substructure of the FOWT. A direct time-domain method was used to calculate the wave-rigid body interaction problem. The proposed numerical scheme offers an effective way of modeling the incident wave by an arbitrary time series.
