FIELD: gas industry; construction.
SUBSTANCE: invention relates to design for storage of liquefied natural gas (LNG) in offshore structure housing compartment containing self-supported primary barrier, secondary barrier surrounding self-supported primary barrier, and space for access between self-supported primary barrier and secondary barrier, where self-supported primary barrier represents self-supported tank LNG and is connected with compartment housing by means of support devices, penetrating into secondary barrier, secondary barrier is impermeable for liquid heat insulation, connected with housing inner surface, and is sealed with support devices with help of flexible watertight seal so that self-supported primary barrier and secondary barrier are connected separately with housing compartment for prevention of force transfer between primary barrier and secondary barrier.
EFFECT: increased structure reliability and manufacture ability.
