The present disclosure relates to a vacuum heat-insulation device for a large low-temperature tank, the vacuum heat-insulation device having excellent heat insulation properties and vacuum stability by using a low-temperature heat-insulating material maintained in a vacuum at all times so as to store an ultra-low-temperature liquefied gas such as liquid nitrogen (LN.sub.2) or liquid hydrogen (LH.sub.2), and to a vacuum heat-insulation device for a low-temperature tank, the vacuum heat-insulation device having a flexible structure in which a vacuum jacket is partially contractible according to contraction of a low-temperature tank or a low-temperature heat-insulating layer.

A double-walled tank including at least one link system linking the outer and inner chambers of the tank and including a central part linked to the inner chamber and at least three blades distributed around the central part, each blade extending between a first end linked to the central part and a second end which has a head linked to the outer chamber, each blade being sufficiently flexible to be deformed elastically between its first and second ends in a direction of displacement.

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.

A cryogenic storage vessel having an inner vessel defining a cryogen space; an outer vessel spaced apart from and surrounding the inner vessel, defining a thermally insulating space between the inner vessel and the outer vessel; and a receptacle defining passages for delivery of liquefied gas from the cryogen space to outside the cryogenic storage vessel. The receptacle has an elongated outer sleeve defining an interior space in fluid communication with the thermally insulating space that is sealed from the cryogen space; an elongated inner sleeve extending into the interior space defined by the elongated outer sleeve defining an inner receptacle space that is fluidly isolated from the thermally insulating space; and a collar extending around an inner surface of the elongated inner sleeve which seals against a cooperating surface of a pump assembly when a pump assembly is installed in the cryogenic storage vessel thereby dividing a warm end from a cold end of the receptacle. A motor for driving the pump can be installed within the cryogenic storage vessel.
