Offshore wind power plant is a new type of power plant that utilizes offshore wind resources to generate electricity. Under the increasingly severe situation of oil resources, all countries have turned their attention to sea areas with huge wind resources. my country is rich in offshore wind energy resources, and the offshore wind energy resources available for development have reached 500 million kilowatts. my country has a vast coastline and abundant offshore wind energy resources, mainly concentrated in the southeast coastal areas.

Since offshore wind power projects are generally located in offshore areas, during wind turbine foundation construction and wind turbine commissioning and operation process maintenance, it is necessary to directly cross the ladder from the professional ship to the wind turbine foundation platform, as shown in Figure 1. At present, due to the lack of reliable access equipment and other facilities to assist in this process, the ship can only be approached to the wind turbine platform, and personnel can jump to the wind turbine foundation ladder by themselves, and there is a certain risk of falling during this process. Especially when the sea waves are large, the hull is constantly swinging, and it is difficult for maintenance personnel to enter the basic operation platform of the wind turbine from the ship.

Therefore, how to provide a device to assist the staff to step over from the professional ship to the ladder on the foundation platform of the wind turbine is a technical problem that urgently needs to be solved by those skilled in the art.
