Offshore Station, Foundation for an Offshore Station, and Method for Building an Offshore Station

Abstract

An offshore station ( 1 ), in particular an offshore wind power station, comprises a floatable foundation ( 2 ) that can be sunk by flooding a hollow chamber, and a superstructure ( 6 ) on which functional units ( 7, 8 ) of the station ( 1 ) are arranged. The foundation ( 2 ) includes a bottom pale ( 3 ), a base ( 4 ) which is disposed on the bottom plate ( 3 ) and projects from the water surface ( 12 ) in the sunk state of the foundation ( 2 ) and on which the superstructure ( 6 ) can be mounted, and a floodable floating device ( 5 ) which surrounds the base ( 4 ) in the shape of a ring. In a method for building an offshore station ( 1 ), in particular an offshore wind power station, a floatable foundation ( 2 ) is prefabricated in a harbor zone, is towed to a mounting location after being prefabricated and is sunk, whereupon the station ( 1 ) is completed with a superstructure ( 6 ) and functional units ( 7, 8 ) of the station at the mounting location. In the harbor zone, a bottom plate ( 3 ) of the foundation ( 2 ) is concreted, a base ( 4 ) of the superstructure ( 6 ) preferably made of prefabricated concrete parts ( 15 ) is mounted on the bottom plate ( 3 ), and a floodable floating device ( 5 ) which surrounds the base ( 4 ) in the shape of a ring is mounted on the bottom plate ( 3 ) and/or the base ( 4 ) once the base ( 4 ) has been mounted.

1 . Foundation ( 2 ) of an offshore station ( 1 ), especially an offshore wind power station that can float and can be sunk by flooding a hollow space characterized in that the foundation ( 2 ) encompasses a bottom slab ( 3 ) and, arranged on the bottom slab ( 3 ), a base ( 4 ), which juts out from the water surface ( 12 ) when the foundation ( 2 ) has been sunk and on which a superstructure ( 6 ) of the offshore station can be mounted, as well as a preferentially annular floating body ( 5 ) constructed around the base ( 4 ) that can be flooded.
