<p>Offshore windmill farm receives visits by ship or helicopter fo rmaintenance and repair work. The windmills have a foundation part which lies partly under the water level and a usage part supported by the foundation part. The foundation part is provided with an inner space under the water level, with a first opening between the inner space and the surrounding sea. A ship can travel and moor under the water level through the opening in the inner space. Each windmill has a mast (1), a gondola (2) and one or more sails (3), which rotate around a horizontal axis. As far as possible, all the wind turbines in the group are constructed from the same components, which facilitates the maintenance and repair functions. Near the turbines is a maintenance work location (5), which has a helicopter pad (6) and a crane (7) for hoisting components onto the work location. The maintenance work location can have other installations for transport of men and materials.</p> |
