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: An electrohydraulic device includes an extender which is arranged to be actuated by hydraulic fluid, and a rotor of an electric motor, the rotor being arranged to rotate about a part of the extender. The rotor may have an annular body which encircles or surrounds part of the extender. There is also described a related method of use and a marine vessel or platform where the device may be applied.

Abstract: Disclosed is a system and method for regenerating and distributing energy, such as employed on a vessel or floating offshore installation, the system including a first power distribution system, a second power distribution system electrically isolated from the first power distribution system, and a flywheel mechanically connected to both the first and second power distribution systems. Each of the first and second power distribution systems may include a motor/generator mechanically connected to the flywheel and a drive module electrically connected to its respective motor/generator. The flywheel drive modules may be connected to a common flywheel control module that includes a control algorithm for operating the system.

Abstract: There is described a system for hoisting a load on an offshore rig, the system comprising a winch having a winch drum; drive means for operating said winch; one or more sheaves; an elongated hoisting member, such as a wire rope, configured to run over said one or more sheaves and to connect said winch to a load, wherein said winch drum, in a first position of use (A), is configured to accommodate only a single layer of said elongated hoisting member.
