A multilayer insulation is provided. The multilayer insulation includes a plurality of layers of material separated from one another by post elements. The interior of the integrated multilayer insulation can be filled with a selected gas. Moreover, the gas can be held in an interior volume of the integrated multilayer insulation at a pressure greater than ambient pressure, or flowed through the interior volume of the integrated multilayer insulation. The integrated multilayer insulation can be placed directly over an object to be insulated, or over a cellular insulation structure that is placed directly on the object to be insulated.

A method for constructing a triple shell tank including an inner tank, an intermediate tank, and an outer tank each having a roof and a side plate includes the following procedure. As construction entrances, a first construction opening is opened in an outer tank side plate, a second construction opening is opened in an inner tank side plate, and a third construction opening is opened in an intermediate tank side plate, each during the installation of the corresponding side plate. The construction openings are opened so as to partially overlap with one another in a circumferential direction and a height direction of the triple shell tank. The first construction opening and the second construction opening are opened so as to satisfy a relationship AR1AR2, where AR1 is an opening area of the first construction opening and AR2 is an opening area of the second construction opening.

A triple shell tank includes an inner tank, an intermediate tank covering the inner tank, and an outer tank covering the intermediate tank. The inner tank includes an inner tank side plate, an inner tank roof, and an inner tank bottom plate. The intermediate tank includes an intermediate tank side plate, an intermediate tank roof, and an intermediate tank bottom plate. The circular steps of the intermediate tank side plate include a lowermost step formed of an intermediate tank side plate piece for height adjustment having a height corresponding to a height difference between the inner tank bottom plate and the intermediate tank bottom plate, and a second step on the lowermost step formed of an intermediate tank side plate piece arranged at a same height position as an inner tank side plate piece of a lowermost step in the circular steps of the inner tank side plate.

A method for constructing a triple shell tank including an inner tank, an intermediate tank, and an outer tank each having a roof and a side plate includes the following procedure. An intermediate tank roof is temporarily fixed onto an inner tank roof, and further an outer tank roof is temporarily fixed onto the intermediate tank roof to form a connected roof body. An outer tank side plate having a predetermined height is installed around the connected roof body. A sealing process is performed between an outer peripheral edge of the outer tank roof and an inner face of the outer tank side plate to form a sealed space, and air is supplied to the sealed space to air-raise the connected roof body. The outer tank roof and the outer tank side plate are fixed. An inner tank side plate and an intermediate tank side plate are installed and the temporary fixing of the connected roof body is released to fix the inner tank roof and the inner tank side plate and fix the intermediate tank roof and the intermediate tank side plate.

A sealed and insulating reservoir contains a pressurized cold fluid in a rigid, sealed enclosure. A fluidtight membrane is positioned to contact the cold fluid contained in the reservoir. An insulating barrier is placed between the fluidtight membrane and the internal surface of the rigid enclosure, with the insulating barrier forming a support surface to support the fluidtight membrane. A pressure balancing device is able to limit the pressure difference between a first sealed volume located inside the fluidtight membrane, and a second sealed volume located outside the fluidtight membrane. The pressure balancing device typically includes a fluid circuit having two chambers sealingly separated by a movable separator. The first chamber is linked to the first sealed volume, and the second chamber is linked to the second sealed volume. The movable separator exerts a loading force in the direction of the second chamber.

This liquid hydrogen storage tank includes a tank body, a dike, a pump, and a housing chamber. The tank body includes an inner tank that forms a storage space for storing liquid hydrogen therein, and an outer tank that is formed by interposing a thermal insulation layer between the outer tank and the inner tank. The dike includes an outer peripheral surface and an inner peripheral surface that is in contact with the side plate of the outer tank. The dike is formed upwardly so as to surround the outer periphery of the tank body. The pump discharges liquid hydrogen inside the inner tank through the side plate of the inner tank to the outside. The housing chamber is disposed between the outer peripheral surface of the dike and the storage space, and houses the pump.

The invention relates to a receptacle for receiving a cryogenic coupling for filling between two uses, the receptacle comprising a tubular sleeve which has an inlet and a bottom and delimits a tubular housing configured to accommodate a coupling of cylindrical overall shape, characterized in that the tubular sleeve is thermally insulated, and in that the bottom is situated above the inlet thereof in a use configuration such that the terminal end of the coupling is held there oriented upwards in a position stowed in the receptacle.

A method for constructing a triple shell tank including an inner tank, an intermediate tank, and an outer tank each having a roof and a side plate. According to the construction method, an intermediate tank roof is temporarily fixed onto an inner tank roof to form a connected roof body, a guide side plate having a predetermined height is installed around the connected roof body, a sealing process is performed between an outer peripheral edge of the connected roof body and an inner face of the guide side plate to form a sealed space, air is supplied to the sealed space to air-raise the connected roof body, at least a part of an outer tank roof is formed on the intermediate tank roof of the air-raised connected roof body, and an outer tank side plate is installed around the guide side plate.

The present invention regards a system for transferral of at least one cryogenic fluid between two objects. At least one transfer pipe extending from the installation extends into a receiving room in the vessel, the transfer pipe being connectable with piping on the vessel through a connection in the receiving room. The receiving room is closable, the connection, and or at least a part of the construction forming the receiving room and or other elements in the receiving room are constructed to withstand eventual leakage of the cryogenic fluid and the system also provides for evacuating the receiving room for eventual spilled fluid. The invention also regards a flange for use in the system.

A multiple-shell tank includes: an inner tank that stores a liquefied gas; an intermediate tank that covers the inner tank and forms a first heat insulating space between the intermediate tank and the inner tank; an outer tank that covers the intermediate tank and forms a second heat insulating space between the outer tank and the intermediate tank; and a communication part enabling an external space that is a space outside the multiple-shell tank and the first heat insulating space to communicate with each other.
