Abstract

An arrangement (1) for placement on a seabed (3) below a body of water (2), for support of a device for the production of electric power from wind, comprises a column (6; 6') having a first end provided with connecting means (8) that project above the body of water when the arrangement is installed on the seabed. At a portion that is below the surface of the body of water when the arrangement is installed on the seabed, the column is connected to three legs (5a-c), the legs at a second end being connected to respective foundations (4a-c) designed for installation on and transfer of forces to the seabed. Each foundation comprises a compartment (11) defined by a plate member (10) which at its periphery is connected to a skirt (9) that extends downwards from the plate element when the foundation is installed on the seabed, such that a substantially closed space (H ') is formed in the compartment. Furthermore, each foundation (4a-c) comprises a ballasting compartment (12) defined by a lower plate member (10) which at its periphery is connected to a portion (13) of the respective leg (5a-c) and an upper partition (29) in the respective leg, and provided with means (27) for the supply of ballast liquid.
