The invention claimed is: 1. Offshore wind turbine (14) including a tower (1) rising above sea level (12) and one or more blades (4), which can be put into rotation by wind, and where the offshore wind turbine includes a pump (6), said pump being adapted to pump sea water (13) up from the sea, characterized by the pump (6) communicating with nozzles (8, 9) at the delivery side, said nozzles being adapted to direct sea water to the surface of the blades (4). 2. Offshore wind turbine (14) according to claim 1, characterized by the blades (4) extending radially out of a hub (15), said blades and said hub constituting a rotor, which is mounted on a substantially horizontal main shaft (17). 3. Offshore wind turbine (14) according to claim 2, characterized by the main shaft (17) being pivotally mounted in a nacelle (2) mounted on top of the tower (1), said nacelle (2) being able to pivot around a vertical shaft in relation to the tower (1), hereby being able to adjust the rotor plane of the blades (4) in relation to the direction of the wind (W). 4. Offshore wind turbine (14) according to claim 1, characterized by said wind turbine including nozzles (8), which are placed between the tower (1) and the blades (4), and which are adapted to spray sea water in the direction of the rotor plane. 5. Offshore wind turbine (14) according to claim 3, characterized by the nozzles (8) being fixed to the nacelle (2), so that said nozzles face the rotor plane irrespective of the orientation of said rotor plane. 6. Offshore wind turbine (14) according to claim 4, characterized by the nozzles (8) being fixed to the tower (1). 7. Offshore wind turbine (14) according to claim 6, characterized by nozzles (8) being fixed along the circumference of the tower (1). 8. Offshore wind turbine (14) according to claim 2, characterized by said wind turbine including one or more nozzles (9), which are placed inside or on the rotor hub (15). 9. Offshore wind turbine (14) according to claim 8, characterized by the nozzles (9) being adapted to generate a cloud (10) from drops of sea water in front of the rotor. 10. Offshore wind turbine (14) according to claim 1, characterized by said wind turbine including a control system for activating the pump (6) and/or the nozzles (8, 9). 11. Offshore wind turbine (14) according to claim 10, characterized by the control system including an ice sensor, which can be placed on a blade (4), the hub (15), the nacelle (2) or the tower (1). 12. Offshore wind turbine (14) according to claim 10, characterized by the system being adapted to activate/deactivate the pump (6) and/or the nozzles (8, 9) by measuring the power of the wind turbine.
