FIELD: gas industry.
SUBSTANCE: invention relates to installation (1) for storage of liquefied gas, comprising support structure (2, 3) and reservoir (71). Reservoir (71) comprises cover (12) located in opening (10) for loading/unloading. Auxiliary sealing membrane is fixed at the point of rupture of the support structure by means of auxiliary connecting ring (21). Lower wall of cover (23) is tightly connected to the main sealing membrane and is attached by means of the main connecting ring (41). Reservoir also contains a heat-insulating ring, which includes a plurality of heat-insulating structures and is formed between the main connecting ring (41) and the auxiliary connecting ring (21). Heat-insulating connecting structures fill the space between the main connecting ring (41) and the auxiliary connecting ring (21) formed by the main heat-insulating barrier and capable to withstand the load created by the main sealing membrane.
EFFECT: simplified design and decreased overall dimensions.
