Abstract: A crane vessel for hoisting of an offshore wind turbine or a component thereof, includes a hull having a deck. A crane configured for hoisting of an offshore wind turbine or a component thereof includes a vertical crane structure having a crane structure base fixed to the hull, the crane structure extending from the hull over a height thereof to a top along a vertical axis of the crane structure, a boom, and a slew bearing allowing to revolve the boom, about a slew axis. A main hoisting system includes at least one main hoisting winch, an associated main hoisting cable and a load connector, the main hoisting cable extending from the main hoisting winch to a main hoist cable guide on the boom and then to the load connector. The crane further includes a dynamic behaviour adjustment system that is configured to adjust the dynamic behaviour of the vessel by moving and/or arranging an adjustment mass that is distinct from the offshore wind turbine or component thereof into or in at least one dynamic behaviour adjustment position along the height of the vertical crane structure.

Abstract: The crane is hoisted from the ground to the nacelle by operating a cable winch at ground whereby a cable extends from the crane to a roller at the nacelle and to the cable winch. A hoist block with the roller is arranged on a jib at a first hoist block position above a second hinge part of a crane base and extended in horizontal direction from the nacelle. When a first hinge part of the crane is positioned at a corresponding second hinge part of the crane base, the cable extends in a downward direction directly from the roller of the hoist block and through a central opening in a pedestal. After mutual connection of the first and second hinge parts, the hoist block is removed from its first hoist block position.

Abstract: A lift system mountable in a nacelle of a wind turbine has a boom having a proximal end mountable in the nacelle and a distal end extending over a hub of a rotor of the wind turbine when the lift system is mounted in the nacelle. The lift system has a frame structure for mounting the proximal end of the boom in the nacelle, a winch mounted to the boom, a fastener situated below the boom and operatively connected to the winch by at least one cable, and a trolley movably mounted to the boom to permit translation of the trolley longitudinally along the boom thereby permitting longitudinal movement of the fastener with respect to the boom.
