Abstract:Offshore floating wind turbine is one of the most potential technology that is capable of exploiting the abundant deepwater wind resource. Because of the existing large motion of the floating platform, the nonlinear and large deformation of the mooring line, the large flexible blades and tower, and the big wind loads applied on the blades, there are big challenges to perform dynamic analysis of the integral offshore floating wind turbine under the wind, current and wave loads. By considering the large platform motions and its special profile, the current status of aerodynamics, hydrodynamics, the dynamics of mooring line system and the rigid-flexible multibody dynamic of the offshore floating wind turbine were discussed, and the limitations and the possible solutions about the load analysis and dynamic modeling were presented. For the coupled aerodynamic, hydrodynamic, and structure dynamic behaviors of the offshore floating wind turbine, it was expected to develop specialized analysis methods and tools from the system viewpoint.
