Offshore wind farms are favored and valued by more and more countries because of their long availability of wind resources, high wind power density, small turbulence, zero emissions and proximity to load centers. However, the offshore wind farm is inevitably adjacent to or even interspersed with the waterway, the fishery, etc., and the wind turbine foundation has the risk of colliding with the relevant ship. Once a ship exceeding the anti-collision standard hits the fan foundation, it will cause partial damage or even collapse of the fan foundation, causing losses to the investor and may have certain adverse social impacts. The anti-collision investigation of offshore wind turbines is indispensable. It is important to accurately feedback the flow field information of the designated area of the wind turbine through software to calculate the annual collision probability of the ship. It is of great significance to implement navigation management measures, early warning measures and anti-ship collision protection measures.
