Abstract:
A fluid storage and pressurizing assembly includes a storage receptacle and a pump assembly. The storage receptacle includes an inner vessel defining a cryogen space for storing a fluid at a storage pressure and a cryogenic temperature, an outer vessel surrounding the inner vessel, and an insulated space between the inner vessel and the outer vessel, and a pump assembly. The pump assembly includes a pump having an inlet disposed within the cryogen space for receiving a quantity of the fluid from the cryogen space, and an outlet for delivering the fluid therefrom, and a pump drive unit for driving the pump, the pump drive unit being at least partially disposed within a space defined by the storage receptacle.

Abstract:
An energy-accumulation apparatus includes a variable-buoyancy assembly configured to be selectively buoyant in a body of water. The energy-accumulation apparatus also includes a delivery assembly coupled to the variable-buoyancy assembly. The delivery assembly is configured to deliver the variable-buoyancy assembly within the body of water between a first position to a second position.
Abstract:
The present invention relates to a tank for high and very high pressure fluids, in particular gases for the power supply of motor vehicles, comprising an airtight core (2) and at least one external covering (3), the core (2) being associated with a reinforcement structure comprising a central body (10) joined to the core (2) and having at least two plates (11a, 11b) at least partly covered by the external covering (3), the two plates being opposite and joined together by means of at least one connection element (12).
Abstract:
This invention is directed to a method of decreasing the rate of escape a gas from a breached containment system by introducing into the containment system a plurality of objects that create a tortuous path for the gas to get to the point of breach thereby substantially reducing the degree of damage done by the breach.
Abstract:
A Hydrogen storage system comprising storage elements coupled to each other to form one or more containers disposed in a space having a volume V where the volume of each of the storage elements is much smaller than the volume V resulting in the storage elements experiencing reduced stress at their inner surfaces. Thus, Hydrogen can be stored at relatively high pressure within these storage elements due to the reduced stress experienced by their inner surfaces. Consequently, materials having relatively lower tensile strength and stiffness can be used to construct the storage elements of the Hydrogen storage system. Further, the storage elements can be shaped and sized to conform to a volume of space having an arbitrary shape and dimensions.
Abstract:
A liquid containment system for a seafaring vessel. The liquid containment system includes a tank having an at least partially non-planar upper portion. The upper portion of the tank contains a substantial portion of the liquid therein and reduces the free surface area associated with the liquid. The upper portion of the tank extends above the horizontal deck of the vessel, but still allows sufficient deck space for supporting various required equipment. In one embodiment, the liquid containment system is a membrane tank designed to receive and hold liquefied natural gas ("LNG").
Abstract:
Réservoir pour gaz naturel liquéfié, comprenant une structure porteuse (11) et une cuve étanche et thermiquement isolée destinée à contenir du gaz naturel liquéfié, chaque paroi de cuve présentant successivement, dans le sens de l'épaisseur depuis l'intérieur vers l'extérieur de ladite cuve, une barrière étanche primaire, une barrière thermiquement isolante primaire, une barrière étanche secondaire et une barrière thermiquement isolante secondaire, la barrière étanche secondaire d'une paroi verticale comprenant une première nappe étanche située au sommet de ladite paroi et un dispositif de liaison reliant, de manière étanche, ladite première nappe étanche à ladite structure porteuse, caractérisé par le fait que ledit dispositif de liaison comprend une première plaque métallique (22) parallèle à ladite première nappe étanche, et une deuxième nappe étanche (17) qui est, d'une part, collée à ladite première nappe étanche et d'autre part reliée à ladite première plaque métallique.
Abstract:
Vorrichtung zur spannungsarmen Kompensation thermisch bedingter Längenänderungen mindestens eine Barriereschicht in einem Tank zur Lagerung und zum Transport von tiefkalten Medien, wobei der Tank in der Art Paneele aufweist, daß unter mindestens einer Barriereschicht mindestens eine Isolierschicht angeordnet ist, wobei die Barriereschicht in Abständen Unterbrechungen in Längs- und/oder Querrichtung aufweisen, wobei über den Unterbrechungen streifenförmige Kompensatoren angeordnet sind, wobei die Kompensatoren aus flexiblem, biegeweichem Material ausgeführt und breiter als die Abstände oder Unterbrechungen sind, und wobei in die Unterbrechungen begrenzende vertikale Ränder der Barriereschicht Einkerbungen eingebracht sind, in die die Kompensatoren eingefügt und darin gasdicht mit dem Werkstoff der Barriereschicht verbunden sind.
Abstract:
