LPG STORAGE Russian patent published in 2023 - IPC F17C3/02 B63B25/16 

FIELD: liquefied gas storage.

SUBSTANCE: installation for storing liquefied gas, containing a supporting structure and a sealed and heat-insulated tank located in the supporting structure. The tank contains first wall (1) of the tank and second wall (101) of the tank, each wall (1, 101) of the tank contains one sealing membrane (4, 104) and one heat-insulating barrier (2, 102). In this case, first bearing wall (3) forms an angle with second bearing wall (103) along edge (100). Heat-insulating barrier (2) of first wall (1) of the tank contains insulating fastening beam (11). Insulating fastening beam (11) includes bottom surface (12) located on first bearing wall (3) and a metal covering element held at a distance from bottom surface (12) by a plurality of shear partitions (14). The supporting structure contains first thrust device (19). Moreover, first thrust device (19) is placed along the edge of insulating fastening beam (11), opposite to edge (100), and is configured to form a stop that limits the movement of insulating fastening beam (11) in the longitudinal direction away from the edge.

EFFECT: improved insulation of the heat-insulating barrier and simpler fastening of the sealing membrane to the supporting structure.
