Ship collision is the main risk for the large-scale floating offshore wind turbine's (FOWT) safety, especially in the deep water zones. The ship collisions for the monopile and jacket offshore wind turbines have been studied abundantly, and this paper focuses on the issue of the operation and maintenance vessel collision with FOWT. The coupled mathematical dynamic model of the vessel and FOWT was built based on the multi-body hydrodynamics in MATLAB/Simulink, and the impact force was simulated using the physical numerical modeling method. The collision process was modeled in the time domain assuming the dynamic positioning system was broken. And then, the effects of the relative impact velocity and the impact locations on the floaters’ response were analyzed. The results show that the magnitude of the impact force is proportional to the relative impact velocity. The dynamic response of roll and yaw degree of freedom of the ship is intense due to its small added mass.The impact location determines the kinetic energy redistribution and the magnitude of the impact force.
