This paper studies the influence of angel between wind and waves on dynamic response of floating offshore wind turbine at an intermediate water depth of 60 meters.Based on OOstar floating foundation,using DTU(Danmarks Tekniske Universitet)10 MW turbine,this paper designs calculation condition,and the time domain response of the floating offshore wind turbines is simulated,and the influence of angle between wind and waves on the dynamic response of the floating offshore wind turbines is analyzed according to the joint distribution probability of wind and wave.The results show that when the wind speed is less than the rated wind speed,the angle between the wind and waves is mainly distributed in the range of±30°,at this time,the wave height is small,the impact on the floating offshore wind turbine dynamic response is weak;in the case of high wind speeds,there is an angle between the wind and waves will cause the wind turbine the lateral response increases more,so there is no need to consider the existence of the angle between the wind and waves of the conditions;The aerodynamic load and mooring force of floating offshore wind turbines are less affected by the angle between wind and waves.In this paper,the study on the effect of wind and wave angle on the response of floating wind turbines provides some reference for the design of floating wind turbines.
