Claims (17)

1. Method of erecting a floating off-shore wind turbine, said wind turbine being modularized in modules comprising a floatation element, one or more tower modules forming a tower, a nacelle and blades, the method comprising the steps of: providing at least one anchorage to the seabed and first and second connecting means connected thereto; submerging a lower part of said wind turbine, the latter being in a non, partly or fully assembled condition, said lower part comprising at least the floatation element; connecting the first connecting means to a lower end of said lower part of the wind turbine; connecting the second connecting means to one of the modules to be arranged above sea level when the wind turbine is in a fully assembled condition; and elevating said wind turbine to an operational level.
2. The method according to claim 1, the wind turbine being in a non or partly assembled condition, further comprising the step of mounting a subsequent module on top of a working surface before elevating said wind turbine to the operational level, said working surface being formed by an upper end arranged above sea level of the submerged wind turbine.
3. The method of erecting a floating off-shore wind turbine according to claim 2, wherein the step of connecting the second connection means is preceded by further submerging the partly assembled wind turbine to provide a new working surface arranged above sea level on an upper end thereof; and mounting an additional subsequent module thereto, and repeating this until the wind turbine has been fully assembled.
4. The method of erecting a floating off-shore wind turbine according to claim 1, the wind turbine being in a non or partly assembled condition, further comprising the steps of: telescoping one or more telescopically arranged tower modules to extend the height of the tower, the upper most module of said telescoped tower modules forming a working surface; further submerging the partly assembled wind turbine as the height of the tower increases to provide a new working surface arranged above sea level on an upper end thereof.
5. The method of erecting a floating off-shore wind turbine according to claim 4, further comprising the steps of further submerging the partly assembled wind turbine to provide a new working surface arranged above sea level on an upper end thereof; and mounting an additional subsequent module thereto, and repeating this until the wind turbine has been fully assembled.
6. The method of erecting a floating off-shore wind turbine according to any of claims 2-5, wherein the working surface is arranged at a height above sea level adapted to the operational range of an onboard crane.
7. The method according to claim 1, the wind turbine being in a fully assembled condition, comprising the step of transporting the fully assembled wind turbine to the erection site in a horizontal or vertical position.
8. The method of erecting a floating off-shore wind turbine according to any of the preceding claims, wherein the submersion and elevation is made by regulating the density of the floatation element.
9. The method of erecting a floating off-shore wind turbine according to claim 8, wherein the regulation of density is made by changing the ratio between water and gas in the floatation element,
10. The method of erecting a floating off-shore wind turbine according to any of the preceding claims, wherein the anchorages comprise anchoring points being evenly distributed in the circumferential direction of the tower.
11. The method of erecting a floating off-shore wind turbine according to any of the preceding claims, wherein the connecting means are pretensioned during elevation of said wind turbine to the operational level.
12. The method of erecting a floating off-shore wind turbine according to any of the preceding claims, wherein the first connecting means are connected to the floatation element.
13. The method of erecting a floating off-shore wind turbine according to any of the preceding claims, wherein the second connecting means are connected to an upper portion of the tower.
14. The method of erecting a floating off-shore wind turbine according to any of the preceding claims, wherein the first and/or second connecting means are arranged in at least two sets each, said sets being connected to the tower/and or the floatation element at different heights thereof.
15. The method of erecting a floating off-shore wind turbine according to any of the preceding claims, wherein the floatation element comprises at least one compartment formed in a tower module in the lower end of the tower or is formed as at least one separate compartment attached to the lower most tower module or the lower end of the tower.
16. The method of erecting a floating off-shore wind turbine according to claim 8, wherein the density is regulated by using a regulation system comprising at least one inlet and at least one outlet, valves connected thereto, a control system and a gas supply system.
17. A floating off-shore wind turbine erected by the method of any of claims 1-16.
