Abstract: An apparatus for supporting a flywheel on a floating vessel includes a support for the flywheel; and a tilt sensor for measuring an angle of slope relative to the Earth, the tilt sensor being arranged to detect a change of an angle of slope of the floating vessel relative to the Earth. The apparatus further includes a driver for manoeuvring the support relative to the floating vessel, based on the measured angle of slope from the tilt sensor, wherein the driver is operable to manoeuvre the support so as to counteract a change of an angle of slope of the flywheel relative to the Earth due to the detected change of an angle of slope of the floating vessel.

Abstract: Described is a tool and apparatus for positioning a blade for a wind turbine the wind turbine including a tower and a rotatable hub on the tower. The tool is mounted on a side of the tower so that the blade is supported on the tower in an initial configuration. The tool includes a first part arranged to be angularly movable relative to a second part for tilting the blade with respect to the tower to position the blade in a position that can allow the blade to be connected to the hub.

Abstract: A system for hoisting a load on a drilling rig includes: a hoisting means having an elongated hoisting member and an elongated hoisting member drive means; a drill string rotation means suspended from an end of the elongated hoisting member; a support structure having a first side and a second side and being adapted to support at least a portion of the weight the drill string rotation means; a first elongated hoisting member guiding means connected to the support structure; and a counterweight connected to the elongated hoisting member at the second side of the support structure. The elongated hoisting member is reeved over the first elongated hoisting member guiding means from the first to the second side of the support structure. The drill string rotation means is suspended from the elongated hoisting member at the first side of the support structure.

Abstract: A winch drum device includes a first winch drum with an outer surface adapted to accommodate axially displaced turns of wire rope and further includes a wire rope storage means, such as a recess, extending at least partially radially in from said outer surface. The wire rope storage means is adapted to accommodate one or more layers of the wire rope. The winch drum device may be incorporated into a winch.
