초록

This paper presents effect of aerodynamic loads on motion response of floating offshore wind turbine. A Matlab code based on blade element momentum (BEM) theory is developed to consider aerodynamic loads acting on NREL 5MW wind turbine blade. The aerodynamic loads are coupeld with time domain hydrodynamic analyses, so-called one-way multi-physics scheme. We apply an Offshore Code Comparison Collaborative Continuation(OC4) DeepCWind platform with catenary mooring of studless chain links. Comparison of peak tensions in mooring lines yields that consideration of aerodynamic loads provides distribution of more elevated peak values than the case that only steady drag loads are considered.
