Abstract:
This invention relates to dicyclopentadiene polymer liners for systems used for the transport of fluids, in particular corrosive fluids and pressurized fluids such as compressed raw natural gas.
Abstract:
A reversible fastening device (50) for reversibly fastening connecting means (51) connecting a first (52) and a second member (53); the connecting means (51) being housed entirely inside the first member (52); and the device (50) being characterized in that, at a first reversible stage, the connecting means (51) are moved from a withdrawn position to an extracted position projecting with respect to the first member (52); and in that the desired reversible fastening of the connecting means (51) connecting the first (52) and the second (53) member is achieved in the extracted position.

Abstract:
A watercraft comprising a diesel fuel tank for fuelling general shipping requirements of the watercraft such as motoring from one location to another, wherein the watercraft additionally has a CNG pressure vessel thereon for storing CNG therein, said CNG being useable by the watercraft, from the pressure vessel, for powering an engine for coastal manoeuvering of the watercraft.
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:
An inspectable pressure vessel (10) for containing a fluid such as CNG, the vessel having a generally cylindrical shape over a majority of its length, at least one opening for gas loading and offloading and for liquid evacuation, at least one stainless steel layer as a first layer (100) for being in contact with the fluid when the fluid is contained within the vessel, the first layer being made of low-carbon stainless steel, and a further external composite layer (200) made of at least one fiber-reinforced polymer layer that will not be in contact with the fluid when the fluid is contained within the vessel.
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 pressure vessel is produced for storing and transporting CNG. The vessel comprises a body defining an internal volume in which the CNG can be stored, and an inlet for loading the CNG into the vessel. The body of the vessel comprises a structural shell made entirely of a fibre-reinforced filament-wound composite material, which is provided with fibres to carry mechanical loads and a matrix to keep the fibres together and to make the composite impermeable to the CNG. Because the vessel is not provided with any liner, the CNG is in direct contact with an inner side of the structural shell.
