[0033] Offshore wind turbine platforms are usually located in deep sea areas, where the sea conditions are more severe, the waves are higher, and the flow is faster. During the operation and maintenance of wind turbine platforms located in deep sea areas, wind turbine operation and maintenance vessels often need to lean against and be fixed to the wind turbine platforms, and then provide a passage board for personnel to pass from the deck of the wind turbine operation and maintenance vessel to the wind turbine platform. However, the waves will impact the wind turbine operation and maintenance vessel, causing the wind turbine operation and maintenance vessel to move vertically, making it difficult for personnel to pass smoothly from the wind turbine operation and maintenance vessel to the wind turbine platform, and the safety is poor.
