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.

Abstract:
A wind farm installation vessel (1) at open see at the area of the off-shore installation site is ballasted to a first draught, at which the cargo main deck (5) is submerged below sea level, and at least two jack-up legs (2) on the wind farm installation vessel are brought into contact with the sea bottom (10), and a barge (11) with parts for construction of the wind farm is received at a cargo main deck of the vessel, following which the vessel (1) is positioned at a particular site of installation and is jacked-up by at least four jack-up legs (2) on the vessel, and a main crane or other lifting equipment on the vessel lifts a part from the barge (11) on the main cargo deck to the wind turbine construction erected from the sea bottom.
