Abstract: An offshore platform for use in combination with an offshore rig comprises an upper deck defining an upper deck aperture which is alignable with a rig aperture of the offshore rig, when said offshore rig extends over the upper deck, to permit objects to extend between the offshore rig and through the upper deck. The offshore platform further includes a sheath arrangement aligned with the upper deck aperture and extending upwardly relative to the upper deck to be alignable with the rig aperture, wherein the sheath arrangement defines a confinement zone for confining objects which pass downwardly from the offshore rig through the rig aperture.

Abstract: A method for operating a microgrid electric power generation system includes delivering energy to an electric power bus at least partially from one or more kinetic generators electrically coupled to the electric power bus, controlling the one or more kinetic generators in response to a change in a load such that a magnitude of a voltage on the electric power bus remains within a predetermined voltage range, and controlling one or more combustion generators electrically coupled to the electric power bus based at least in part on an operating state of the one or more kinetic generators. The one or more kinetic generators are capable of (a) delivering energy stored therein to the electric power bus, and (b) storing energy in kinetic form.

Abstract: A flywheel system includes a rotor and a fixture. The rotor forms an aperture. The fixture includes a bottom support, a top support, and a shaft connecting the bottom support to the top support. The shaft passes through the aperture. The bottom support and the top support are outside opposite ends of the aperture. The rotor is configured to rotate about the shaft. A method for operating a flywheel system includes converting between rotational energy of a rotor and electrical energy in windings of a generator stator that is implemented in a stationary shaft passing through an aperture of the rotor, while the rotor is rotating about the shaft.
