Abstract
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.
