Abstract: Offshore wind energy resources are abundant along the coastal areas of China, although they are subjected to poor marine geological conditions and frequent extreme weather conditions. The stability of the foundation of an offshore wind turbine determines the quality and safety of the entire project. In order to adapt to the poor marine geological conditions and reduce the cost of construction and operation of offshore wind turbines, this study innovatively proposes a new foundation type of offshore wind turbines, a pile-friction ring foundation. The p-y curve method is used to simplify the pile-soil-water coupling effect. The Kaimal wind spectrum model is used to simulate the turbulent wind field and calculate the aerodynamic load, and the Morrison equation is used to calculate the wave load of the offshore wind turbine. The advantages of the proposed foundation are demonstrated by comparing the dynamic response of wind power structures with monopile foundation and pile-friction ring foundation. The results show that the friction ring can effectively suppress the structural vibration of the offshore wind turbine by increasing the resistance of the pile side, the foundational stiffness and the equivalent mass.
