A wind-driven power station mounted floating in deep water, comprising a machine house (8) including a generator (not s shown), regulating devices (not shown), rotor axle (9) and rotor blade (10), in which the machine house (8) is mounted at a tower (2) that mainly is floating in an upright position
A wind-driven power station mounted floating in deep water, comprising a machine house (8) including a generator (not s shown), regulating devices (not shown), rotor axle (9) and rotor blade (10), in which the machine house (8) is mounted at a tower (2) that mainly is floating in an upright position, and where the stability of the tower (2) is provided by means of ballast (5, 6) being placed in the lower part of the tower (2). The power station is kept in position and stabilized by means of anchor systems ( 12, 13, 14, 15, alternatively 16, 17, 18).

The invention claimed is: 1. A wind-driven power station that is mounted in a floating state in water, comprising: a tower; a windmill connected to an upper part of the tower; an anchor rod connected to a lower part of the tower under tension; a bottom anchor secured to a sea bed; and a joint conne
The invention claimed is: 1. A wind-driven power station that is mounted in a floating state in water, comprising: a tower; a windmill connected to an upper part of the tower; an anchor rod connected to a lower part of the tower under tension; a bottom anchor secured to a sea bed; and a joint connecting the anchor rod and the bottom anchor, wherein the tower is permitted to float, to an essential degree, in an upright position, because the total center of gravity of the wind-driven power station is located below the buoyancy center of the wind-driven power station, wherein the anchor rod under tension and the joint provide a torsionally rigid connection, preventing rotation of the tower due to torque transmitted by the windmill; and wherein the joint allows the tower to tilt to the side due to strains caused by wind, waves and currents in the water. 2. An arrangement as claimed in claim 1, wherein a ballast room filled with a ballast material and a ballast tank arranged to accept liquid ballast are arranged in the lower part of the tower. 3. An arrangement as claimed in claim 1, wherein the anchor rod is connected to an upper joint that is fastened to a lower portion of the tower, each joint being arranged for transfer of torsion and tensile forces. 4. An arrangement as claimed in claim 3, wherein the upper joint is a tilting joint. 5. An arrangement as claimed in claim 1, wherein a machine house is positioned in such a way that, during operation, rotor blades of the wind-driven power station are positioned on the leeward side of the tower. 6. An arrangement as claimed in claim 1, wherein a generator is mounted in the tower and connected to a rotor axle by means of a transmission arrangement. 7. An arrangement as claimed in claim 1, wherein the tower and a floating substructure consist of a single body. 8. An arrangement as claimed in claim 1, wherein portions of the tower or the entire tower have a cylindrical cross section. 9. An arrangement as claimed in claim 1, wherein the tower consist of an upper and a lower section. 10. A wind-driven power station that is mounted in a floating state, comprising a tower floating, to an essential degree, in an upright position because the total center of gravity of the wind-driven power station is located below the buoyancy center of the wind-driven power station, wherein the wind-driven power station is positioned and stabilized by means of a torsionally rigid connection to the bottom of the sea, wherein the torsionally rigid connection comprises an anchor rod under tension, and wherein a tilting joint is placed in the transmission between a machine house and the tower to keep a rotor axle in a horizontal position even if the tower is tilting. 11. A wind-driven power station that is mounted in a floating state in water, comprising: a tower; a windmill connected to an upper part of the tower; an anchor rod connected to a lower part of the tower under tension; a bottom anchor secured to a sea bed; and a joint connecting the anchor rod and the bottom anchor, wherein the tower is permitted to float, to an essential degree, in an upright position, because the total center of gravity of the wind-driven power station is located below the buoyancy center of the wind-driven power station, and wherein the tower exhibits the shape of a single pole with a draft of at least 8 times the average diameter of the submerged part of the tower.
