Abstract
A wind turbine (1) has a base (5) divided into at least three ballast tanks (12). A vessel (7) has means for displacing the wind turbine between a loading space (25) and an unloading position (26). At its unloading position the vessel has winches (11) with at least three flexible lines (10) that can be connected with horizontally distanced lifting points (23) on the wind turbine base.
Claims27
A combination of a vessel and at least a wind turbine base transportable by the vessel, wherein the vessel has a loading space sized for receiving said wind turbine base, which wind turbine base is in an upright position corresponding to an upright operating position of said wind turbine base during placement on said loading space, said vessel having means for displacing said wind turbine base from the loading space to an unloading position, said vessel having winches with at least three flexible lines with associated fastening means arranged for mounting on at least three lifting points on said wind turbine base, which flexible lines are arranged at the unloading position so that their sections, when extending down to said lifting points on said wind turbine base at said unloading position, are spaced apart in the horizontal direction, and wherein a ballast condition of the wind turbine base is variable for adjustment at said unloading position.
A combination of a vessel and at least a wind turbine base transportable by the vessel, wherein the vessel has a loading space sized for receiving said at least one wind turbine, said wind turbine base being in an upright position corresponding to an upright operating position of said wind turbine base when placed on said loading space, said vessel having means for displacing said wind turbine base from the loading space to an unloading position, said vessel having winches with at least three flexible lines with associated fastening means arranged for mounting on at least three lifting points on the wind turbine base, the flexible lines being arranged at the unloading position so that their sections extending down to mounting places on the wind turbine base are spaced apart in the horizontal direction, and a ballast condition of the wind turbine base is variable for adjustment at said unloading position, and wherein the vessel has ballast means for changing the ballast condition of the wind turbine base, which ballast means comprise a pump system for liquid with a plurality of hoses configured for connection on the wind turbine base.
A combination of a vessel and at least a wind turbine base transportable by the vessel, wherein the vessel has a loading space sized for receiving said wind turbine base, said wind turbine base being in an upright position corresponding to an upright operating position of the wind turbine base when placed on said loading space, said vessel having means for displacing the wind turbine base from the loading space to an unloading position, said vessel having winches with at least three flexible lines with associated fastening means arranged for mounting on at least three lifting points on the wind turbine base, the flexible lines being arranged at the unloading position so that their sections extending down to mounting places on the wind turbine base are spaced apart in the horizontal direction, and said wind turbine base which is divided into at least three chambers at least three of which act as ballast tanks, and wherein the vessel has ballast means for changing the ballast condition of said wind turbine base at said unloading position.
