At present, offshore wind power is developing continuously in Bohai bay. Ice-induced vibration response is an important problem faced by offshore wind turbines in Bohai bay. Based on the integrated numerical analysis software of offshore wind turbines, the dynamic response of single pile offshore wind under floating ice load is studied. This paper focuses on investigating the variation law of load dynamic response of monopole offshore wind turbines, studies the influence of different ice load numerical models, ice thickness, and ice velocity on monopole offshore wind dynamic response, and carries out the influence law of single pile offshore wind dynamic response of icebreaking cone structure. The results show that the calculation results under different ice load numerical calculation models are quite different. The tower foundation load and mud line load calculated by Matlock double tooth model are the largest, which are 2.2 times and 1.3 times of that without floating ice, respectively; The dynamic response of single pile offshore wind turbine increases with the increase of ice thickness, and the change of ice velocity has no obvious effect on the structural load of single pile offshore wind turbine. After the ice-breaking cone is adopted, the ice load acting on the single pile offshore fan is significantly reduced, and the shear and bending moment at the tower foundation and mud surface line of the monopile offshore wind turbine are greatly reduced. The maximum values of the shear and bending moment at the tower foundation are 82% and 95% of the structure without an ice-breaking cone, respectively. At the same time, the ice-breaking cone structure can greatly reduce the ice load on the structure,and its maximum ice load and standard deviation are 5% and 7% of that structure without an ice-breaking cone, respectively.
