In a membrane type heat insulation system for a cryogenic liquefied gas carrier cargo tank and a liquefied gas fuel container, a secondary heat insulation layer comprises a plurality of panels which are stacked in multiple layers while each pair of upper and lower panels is arranged to intersect each other, whereby heat loss which may occur in the gap between the panels can be minimized and deformation due to a temperature difference can be minimized.

Disclosed is a membrane type insulation system for LNG carrier cargo tank and liquefied gas fuel container wherein a corrugation finishing membrane formed of Invar steel is welded to a secondary membrane connecting portion or a primary membrane connecting portion in order to seal corrugations at a corner portion of a cargo tank in a structure wherein at least one of a primary membrane and a secondary membrane is formed of an SUS material having corrugations, thereby improving work efficiency while reducing manufacturing costs through elimination of a separate angled piece for connection between corrugations on adjacent walls at the corner portion.

The invention discloses a bimetallic cryogenic membrane storage compartment for liquefied natural gas (LNG) storage. The invention is based on the design of bimetallic membrane panels and two insulating panels to achieve two completely independent insulation spaces, fully meeting the relevant requirements of the amendments to the International Code for the Construction and Equipment of Ships Carrying Liquefied Natural Gas in Bulk (“IGC CODE”) adopted on May 22, 2014. The invention improves the safety of the cryogenic membrane storage compartment, reduces the limitation of free liquid level loading of liquid cargo in the cargo compartment, reduces the application and time consuming of low-temperature resistant glue in the construction process, and adopts the more mature and safe design method of welding bimetallic membrane panels and the environmental protection method of prefabricated foam insulation panels, thus reducing the construction workload, shortening the construction cycle and improving the safety of the equipment.

The present invention is a tank for storing pressurized gas. The tank comprises at least one tubular element (1) having a wall comprising a layer of prestressed concrete (6), at least one circumferential mechanical reinforcing layer (8), at least one axial mechanical reinforcing layer (7) and a sealing layer (5). The concrete from which the layer of prestressed concrete is made is chosen from ultra high performance fiber-reinforced concretes.

A liquid cryogen stored in a liquid cryogen space of a closed insulated cryogenic storage vessel is subcooled by allowing it to enter into a conduit disposed in the liquid cryogen space where it is expanded by a pressure reducer in the conduit, thereby producing a cooled biphasic mixture of the cryogen in liquid and vaporized forms. The cooled biphasic mixture has a temperature lower than that of the liquid cryogen in the liquid cryogen space. Heat is transferred across the conduit from the liquid cryogen in the liquid cryogen space to the cooled biphasic mixture.
