Claim 12:
13. A method for installation of a wind turbine on an offshore substructure, the method comprising:
clamping a tower of a wind turbine in an upright position by a multi-functional clamp comprising a main body configured to selectively clamp and unclamp the tower of the wind turbine, the main body shaped to couple with a crane vessel to define a designated position for the tower of the wind turbine with respect to the crane vessel, and a plurality of hooking members extending from the main body, each hooking member configured to selectively secure and release a respective free end of a rigging assembly of a lifting crane of the crane vessel to the main body;
assembling the wind turbine by the lifting crane of the crane vessel while the multi-functional clamp retains the tower of the wind turbine in the upright position;
constraining a part of the rigging assembly into a guide of a stability frame clamped to an upper part of the tower of the wind turbine;
lifting the wind turbine by anchoring the rigging assembly of the lifting crane to the multi-functional clamp; and
lowering the wind turbine on the offshore substructure.
