Claim 20:
21. A method for on-board loading and commissioning of a mast (140) with a mounted rotor on-board in a buoyancy body (110), comprising the steps of:
placing the mast (140) with the rotor in a horizontal on-board loading position (140b) on a movable rig (170) on a quay, ashore or on a floating unit on water, the buoyancy body (110) ballasted with water for receiving the mast (140) in which the buoyancy body (110) is positioned adjacent the movable rig (170);
pumping out water ballast (146) for weight transfer of the mast (140) with the rotor; and
rotating the mast (140) with the rotor, with center of gravity in support, to different positions of the mast selected from a normal operating position (140a), on-board and maintenance position (140b), and survival position (140c).
