Abstract:
A buoy system for at least one of a) loading natural gas from a gas well or gas storage facility to a ship or b) offloading natural gas from a ship to a gas delivery network or storage facility, the buoy system comprising one or more offshore wave energy converter (OWEC) such that the buoy system is able to gather and store wave energy to be used during the relavant one or both of loading or offloading practices.
Abstract:
A gas loading or offloading system comprising, respectively, at least one loading or offloading arm, the arm having a pipe therein, the arm or the pipe, or both, having a hybrid metal-composite structure including a composite structural over-wrap.
Abstract:
A storage system for compressed natural gas which includes at least one storage vessel for storing CNG and a cooling station wherein the storage vessel is connected to the cooling station so that CNG may be stored in the storage vessel after had been passing through the cooling station and once the stored gas conditions fall out a set range, it is cooled in the cooling station, and returned to the storage vessel, wherein the storage vessel is thermally insulated from the exterior thereof thanks to the composite materials and especially glass-reinforced polymers whose pressure vessels are made.
Abstract:
A vessel emptying system for emptying CNGs from a vessel used to transport CNG, the vessel being one of a plurality of cylindrical containers that are arranged vertically, with substantially parallel axes, wherein said system is arranged to expand the CNG through a turboexpander-compressor device (40, 50), the turboexpander-compressor device (40, 50) being adapted to use kinetic energy from the resulting rotation or movement of that turboexpander-compressor device (40, 50) in a secondary gas processing step of the system. publication
Abstract:
A system for offloading a compressed fluid from a series of pressure vessels, the system comprising a multilevel piping system and at least one ejector device, the ejector device being for recovering energy from a high pressure fluid stream from a substantially full pressure vessel, and for forced suction of residual fluid from a part offloaded pressure vessel, the multilevel piping system comprising, in use, at least three different pressure levels, including a high pressure line, a medium pressure line and a low pressure line, the high pressure line being intended to supply the said ejector device with the high pressure fluid stream, the medium pressure line being intended for both the forced suction of the residual fluid and mixing with the high pressure line, and the low pressure line being intended for each of mechanical suction of the residual gas not drawn off by the ejector, recompression thereof by means of at least one compression turbomachine, and assisting energy recovery by transferring heat via gas/gas exchangers.
Abstract:
A system for loading and storing CNG onboard of a barge and for unloading it therefrom comprises CNG loading facilities for loading CNG on board of the barge, CNG storage facilities for storing the loaded CNG on board of the barge at nominal storage pressure and temperature, and CNG unloading facilities for unloading CNG to a delivery point. The delivery point requires the unloaded CNG to be at delivery pressure and temperature generally different from the storage pressure and temperature. Thus, the CNG unloading facilities comprise a CNG heater for heating the to-be-unloaded CNG prior to unloading, and a lamination valve for allowing the to- be-unloaded CNG to expand from its storage pressure to the delivery pressure. A compressor may also be provided to compress CNG that would not otherwise be spontaneously delivered.
Abstract:
A system for containing and transporting natural and compressed gas by ship, with cylindrical containers arranged vertically with parallel axes characterized by the fact that the said containers (100, 200) have equal heights but at least two different diameters, wherein two of the said diameters fall between 1 m and 6 m, the containers being combined in standardized modules (40), where the said cylindrical containers (100, 200) have a diameter respectively between 3 m and 6 m for a larger size of the containers (100) and between 1 and 2.5 m for a smaller size of the containers (200).
Abstract:
An ISO modal container for storage and transportation of a CNG pressure vessel comprises a main longitudinal portion and two end caps, one at each end of the main longitudinal portion. The container comprises a frame body for housing the pressure vessel inside said frame body. The frame body comprises two sides connected by longitudinally extending beams. A pair of attachments, one at each end of the pressure vessel, holds the pressure vessel suspended in place inside the frame body, with the longitudinal portion of the pressure vessel substantially parallel to the longitudinally extending beams of the frame body of the container. The pressure vessel is supported at, or in cooperation with, its end caps rather than being supported on its longitudinal main body.
Abstract:
A ship comprising a plurality of pressure vessels, there being a first set of pressure vessels of a first length, a second set of pressure vessels of a second length, and a third set of pressure vessels of a third length, the first, second and third lengths differing from one another. The vessels are typically arranged vertically, and the ship can be a multi-hull ship.
