Method and transport unit for carrying out the method for changing oil in gearboxes and other facilities in wind energy plants in the offshore area.

摘要

Method for changing oil in gearboxes and other facilities in offshore wind turbines, in which tanks for used oil, flushing oil and fresh oil arranged in a transport unit, in particular a ship, are successively connected to the respective facility in the wind turbine via hoses, and the used oil is drawn off with flushing oil rinsed and then fresh oil is supplied, and the hoses are separated from the facilities of the wind turbine, characterized in that the transport unit carries at least two transportable containers (1, 2), each of which contains a portion of the equipment for self-sufficient oil change, namely the container (1 ) the supply technology and the container (2) the oil tanks, the containers (1, 2) are transferred from the transport unit with its own crane or the auxiliary crane of the wind turbine to a platform on the tower shaft of the wind turbine and are secured there, then the equipment in the containers (1, 2) are connected to each other, then the hoses (9) for used oil / flushing oil and fresh oil as well as the used oil pump (7) from the container (1) from the reel to the nacelle and connected to the respective facility of the wind turbine and the oil exchanged and, if necessary, the gear unit flushed with flushing oil after the used oil has been extracted, then the hose connections are drawn in and the equipment of the containers (1, 2) separated from one another and transferred back to the transport unit or taken over by it.
