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.

Sealed and thermally insulating tank incorporated into a polyhedral bearing structure, the tank having a plurality of tank walls, a thermally insulating barrier and a sealed membrane, a first bearing wall and second bearing wall forming an edge corner, the thermally insulating barrier of a first tank wall having a row of edging blocks, a row of anchor strips anchored to the second bearing wall by a row of anchor rods, a first and second of edging blocks each having a groove formed in thickness of said edging block, a first and a second of said anchor rods being housed respectively in the groove of the first and second edging blocks, one anchor strip in the row of anchor strips is supported overlapping the first edging block and the second edging block, the anchor strip being coupled to the first anchor rod and to the second anchor rod.

Sealed and thermally insulating tank incorporated into a polyhedral bearing structure, a first bearing wall and a second bearing wall forming an edge corner, the tank having a first tank wall, a thermally insulating barrier and a sealed membrane, the tank further has an angle bracket with a first flange and a second flange in such a way that the angle bracket connects in a sealed manner. The sealed membrane of the first tank wall and the sealed membrane of the second tank wall in line with the edge corner, in which the angle bracket has a pair of first tabs and a pair of second tabs, the tank has a pair of first anchor rods coupled to a respective first tab and a pair of second anchor rods coupled to a respective second tab in such a way as to transmit a tensile load between the angle bracket.

A cryogenic liquid storage system is provided that includes a primary container, an insulation portion, a secondary container, and a pressure release feature. The primary container includes a metal sidewall and a metal dome. Alternatively, the primary container may be constructed out of composite material. The primary container may be configured to retain liquid hydrogen. The insulation portion covers the primary container. The secondary container includes a composite material that covers each of the primary container and the insulation portion. The pressure release feature is disposed through each of the primary container dome, the insulation portion, and the secondary container dome.

The present invention relates to a fuel tank arrangement of a marine vessel including a fuel tank for Liquefied Natural Gas, the fuel tank having a shell, a heat insulation in connection therewith, connections for a pipeline for bunkering LNG to the fuel tank, a pipeline for taking boil-off gas from the fuel tank and a pipeline for taking LNG from the fuel tank, and a deep well pump for pumping LNG from the tank to the pipeline, wherein at least one recess is extending inwardly from the shell and being arranged on top of the fuel tank, the deep well pump being installed in the at least one recess.

A storage container for cryogenic liquids comprising an inner container which encloses a volume for receiving a fluid medium, an outer container which encloses a volume in which the inner container is arranged, with the result that an interspace is formed between the inner container and the outer container, and wherein the outer container has at least one outerfoot by means of which the storage container can be supported on an underlying surface, wherein the at least one outerfoot takes the form of a hollow body, and wherein the inner container has at least one inner foot for supporting the inner container that projects into the interior of the at least one outer foot.

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.

This application discloses a new type of suction leg, an offshore caisson, a sit-on-bottom supporting platform. The suction leg includes a sealing long pile, this sealing long pile including a tubular pipe and a top head connected tightly to the tubular pipe to form cylindrical integral structure with sealing top and opening bottom. The top head has at least one opening to be able to open or close. The sealing long pile can be penetrated into the seabed by a gravity penetration method or/and a suction pile penetration method, or pulled out from the seabed by a buoyancy uplift method or/and a suction pile uplift method.

A steel plate and concrete composite tank unit, tank groups and offshore platforms with new type of tank units are disclosed. The tank unit comprises an outer concrete tank that comprises an outer tank shell, two heads and ring shell connections at both ends, an inner steel tank that comprises an inner tank shell, epitaxial structures at both ends of the inner steel tank. Inner tank shell is connected to the outer tank shell by epitaxial structures, and an isolation layer that is formed from the gap between the outer concrete tank and the inner steel tank where it is filled with isolation medium.
