| 摘要 |
The invention relates to a method for installing (or replacing) a unit (110a, 110b) on the tower (100) of an offshore wind turbine, which unit comprises a rotor consisting of a hub and one or two rotor blades, and a nacelle receiving a gearbox and a generator. The method is characterized by pre-assembling the substantially functional unit (110a) ashore or on a platform, placing the functional unit (110a) on a watercraft (10) in such a manner that the center of gravitation of the unit (110a) lies in the region of the longitudinal axis of the watercraft (10) and the rotor blades extend in the longitudinal direction of the watercraft (10), transporting the functional unit (110a) to the site of the offshore wind turbine, optionally detaching the unit (110b) to be replaced from the tower (100) of the offshore wind turbine, optionally detaching the unit (110b) to be replaced from the tower (100), using a crane (40) aboard the watercraft (10), optionally placing the unit (110b) to be replaced on the watercraft (10), lifting the functional unit (110a) from the watercraft (10) using the crane (40) aboard the watercraft (10), placing the functional unit (110a) on the tower (100) of the offshore wind turbine, fastening the functional unit (110a) on the tower (100) of the offshore wind turbine, and optionally transferring the replaced unit (110b) ashore by means of the watercraft (10). |
