Abstract: The invention relates to a vessel for installation of a pile for supporting a wind turbine, the vessel comprising a hull, a lifting device, and a pile gripper. The lifting device comprises a base, an elongate, upright superstructure, and a lifting assembly and the pile gripper comprises a gripper base and a gripper device. According to the invention, the pile engagement device and the gripper device are, by respective movabilities thereof in an X-Y plane relative to the vessel, whilst both engaging a pile, and whilst supporting the pile, simultaneously movable relative to the hull from an inboard retaining position in which the pile engagement device is in the upper position and the pile is above the hull, to an outboard installation position of the pile in which the pile is outside the contour of the vessel.

Abstract: A semi-submersible service vessel (100) for a floating installation (102) has a hull (104) and a ballasting system. The ballasting system is arranged to selectively lower the hull (104) to a first draft and raise the hull (104) to a second draft. The second draft is smaller than the first draft. At least one submersed elongate lifting fork is fixed to the hull (104) and is configured to extend across the underside of the floating installation (102) and engage the underside of the floating installation (102) when the hull (104) is raised from the first draft to the second draft. Wherein the at least one lifting fork is arranged to lift the entire floating installation (102) when the hull (104) is raised from the first draft to the second draft, and a method of servicing a floating installation (102) with a semi-submersible service vessel (100).

Abstract: An offshore floating structure (100) comprises a floater (200) with positive buoyancy and a keel (300) with negative buoyancy, as well as active and passive suspenders (400) connecting nodes of the keel (300) and the floater (200) with each other. When the keel (300) at the offshore site is lowered by making the active suspenders (440) longer, the passive suspenders (420), which have a fixed length and are held taut, causes the keel (300) to rotate about the vertical during lowering.
