A sealed and thermally insulating tank including a thermally insulating barrier suitable for being anchored to a load-bearing structure is disclosed. The thermally insulating barrier including a plurality of insulating panels juxtaposed in a regular pattern, two adjacent insulating panels defining an inter-panel space, the inter-panel space including an outer portion and an inner portion superposed in the direction of the thickness of the thermally insulating barrier, the outer portion being suitable for being situated close to the load-bearing structure and the inner portion being close to the inside of the tank, the tank further including insulating seals, the insulating seals including two outer insulating seals, the said outer insulating seals being arranged juxtaposed in the outer portion of the inter-panel space so that they have two adjacent edges, and an inner insulating seal, the inner insulating seal being arranged in the inner portion of the inter-panel space.

A heat-insulating container being used under an environment where exposure to water of liquid is possible, includes a container main body having a substance holding portion which holds a substance at a temperature which is lower than a normal temperature on the inside of the substance holding portion; and a heat-insulating structure body which is provided in the container main body and includes at least a vacuum heat-insulating material. In addition, the vacuum heat-insulating material includes an outer cover material and an inner member sealed in a tightly closed and decompressed state on an inside of the outer cover material. In addition, the inner member is configured of a material which does not generate hydrogen in a case of coming into contact with the moisture of the liquid.

A sealed and thermally insulating tank intended for the storage of a fluid, the tank having a secondary insulating barrier having juxtaposed insulating panels; and a primary insulating barrier having insulating panels that are each arranged straddling at least four secondary insulating panels and anchored to the latter. The sealed tank is equipped with a through-element passing through a specific zone of the wall. In the specific zone of the wall, the longitudinal directions of the primary panels are perpendicular to the longitudinal directions of the secondary insulating panels. The through-element passes successively through an opening made in one of the secondary insulating panels and an opening made in one of the primary insulating panels.

A tank (12) for transporting cryogenic fluids, comprising an outer container (10) and an inner container (11), having between them a compartment. The inner container (11) is adapted to contain a cryogenic fluid, which is brought outside the tank (12) through at least one cryogenic fluid withdrawal pipe (13), preferably made of stainless steel. The cryogenic fluid withdrawal pipe (13) is connected to the outer container (10) through a connection system (22) comprising a tubular bimetallic joint (14), which has an outer wall (15), adapted to be welded to the outer container (10) of the tank (12), and a central end or terminal (16), adapted to be welded to the cryogenic fluid withdrawal pipe (13).

A mount for a double-walled vessel includes a first support to support the mount against an outer wall of the double-walled vessel, a second support to support the mount against an inner wall of the double-walled vessel, and a flexible member connecting the first support and the second support. The first support and can be arranged at a first end of the flexible member and the second support can be arranged at a second end of the flexible member opposite to the first end. Further described are a vessel including at least one such mount as well as a vehicle including such vessel.

The invention is directed to a method of insulating tanks having a capacity between 200 m.sup.3 and 20,000 m.sup.3 used for storage of oil and oil products. In the method, foundation elements, including tank bottom heat insulation, are prepared. The tank is mounted on the prepared foundation, then insulation of the tank walls and roof is installed. Supporting relieving skirts are mounted on the tank walls and roof, forming tiers. The tiers are filled with foam glass blocks having expansion joints. A top coat of metal sheets is mounted on the outer surface of the blocks. Foam glass blocks in the lower tier are made to be removable to provide access to a wall-bottom corner weld joint, and the blocks of the remaining tiers are fixed to the tank surface and interconnected with an adhesive material.

The present invention relates to the use of a layer of a material as a thermal insulation barrier on an interior surface of wall of a containment system for a fluid, wherein the cryogenic fluid is one of liquid natural gas (LNG), liquefied nitrogen, liquefied propane, liquefied oxygen, liquefied carbon dioxide and liquefied hydrogen, the material having a contact angle which is at least 150.
