Abstract:
A method of producing a pressure vessel, and the corresponding pressure vessel, wherein the pressure vessel is comprised of different types of structural elements, one of the structural elements being comprised of a metal substrate having a liner material adhering to the substrate in adjoining linear areas; and orientated so that adjoining linear areas of lining material are orientated longitudinally with respect to a completed pressure vessel.
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 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:
The present invention discloses an inside mobile ballast arrangement for sailboats, said arrangement using a dense material and being preferably in a watertight/gas-tight compartment, the whole system on low friction bearings and being close to the bottom of the hull, this arrangement being able to move longitudinally from front to rear and vice versa, along the X axis, independently or simultaneously with a perpendicular displacement, i.e. from port to starboard and vice versa, along the Y axis.
Abstract:
A method of manufacturing a composite part where a layup is covered with a vacuum bag to which a reduced pressure is applied, the method including providing a uncompressible breather element between the layup and the bag to assist with airflow over a surface of the layup.
Abstract:
A modular element, adapted to serve as a scaffold for cell cultivation, comprises a degradable, preferably biodegradable, thermoplastic sheet and a support structure therefor structure therefor comprising a frame that permits fluid communication with both sides of the sheet, the sheet having a microstructure on at least one side thereof, and wherein said modular element is stackable, such that the gap between sheets of adjacent, stacked modules is permissive of the bridging of said gap by a cell culture or cultures located on one or more sheets bounding said gap, and wherein the modules can advantageously be assembled into a structure resembling a tissue or organ sample, with eventual removal of the sheet and support. Such modules can easily be manufactured and handled.
