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 connection having at least one double-walled pipe of stainless steel connected to an LNG tank is disclosed, the LNG tank having an inner shell of stainless steel and an outer shell spaced at a distance from the inner shell, the inner and outer shells defining an isolation space therebetween. The at least one double-walled pipe includes a common outer wall and at least one inner pipe. The outer wall of the pipe is connected to the inner shell of the tank in such a way that the outer wall and/or a pipe fitting of cold resistant material between the inner shell and the outer wall is arranged to compensate for changes in the length of the outer wall of the pipe and/or of the pipe fitting due to temperature differences between the outer wall of the pipe and the inner shell of the tank.

The present invention includes: an independent tank constituting an inner tank to store a storage material therein; at least one sandwich plate modularized and manufactured include a metal plate provided in a pair opposite to each other, the metal plates having a reinforcing material formed therebetween, and a filler filled between the metal plates, the at least one sandwich plate surrounding the outer surface of the independent tank to constitute an outer tank; and an external reinforcing member formed on the outer surface of the sandwich plate.

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.

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.

A storage container includes a wall structure defining an interior, where the interior is configured to contain a fluid. A portion of the wall structure is formed by a composite material. The composite material includes frozen water and a fibrous additive.

There is provided a method for constructing a cylindrical tank, including the step of assembling a metal inner tank by individually and sequentially conducting, on an internal side of a PC wall, raising of an inner tank lateral plate by a jack-up unit and welding of a next-stage inner tank lateral plate onto a lower section of the raised inner tank lateral plate, further including the step of installing a guide pair configured to sandwich the raised inner tank lateral plate onto the next-stage inner tank lateral plate that is to be welded therebeneath. As a result, in the case of adopting the jack-up construction system, it is possible to prevent an inner tank lateral plate from being attached next from falling.

The invention relates to an insulated chamber comprising at least one element that may operate at sub-ambient temperature, the space around the element(s) being filled with solid insulation and means for injecting a gas containing at least 95 mol-% nitrogen into the insulation, at least some of the gas-injection means opening at a position vertically above at least one element to insulate.

A triple containment tank includes: a tank foundation; a triple shell including an outer tank, an intermediate tank, and an inner tank; a first anchor strap extending through a first inter-tank region and a second inter-tank region and coupling an inner tank side plate and the tank foundation; and a second anchor strap extending through the second inter-tank region and coupling an intermediate tank side plate and the tank foundation. The first anchor strap includes: a first end portion coupled to the inner tank side plate; a second end portion coupled to the tank foundation; a first intermediate portion located between the first end portion and the second end portion and coupled to an inner wall-side portion of the intermediate tank; and a second intermediate portion located between the first end portion and the second end portion and coupled to an outer wall-side portion of the intermediate tank.

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.
