HEAT-INSULATING SEALED TANK Russian patent published in 2022 - IPC F17C3/02 

FIELD: transportation.

SUBSTANCE: group of inventions relates to a heat-insulating sealed tank, a fluid transportation vessel, a fluid transfer system, and a method for loading and unloading a vessel. The tank contains tank wall (1) fixed to supporting wall (3), in which an auxiliary insulating barrier contains a set of auxiliary rows (A, B, C) parallel to the first direction and located adjacent to each other in the second direction perpendicular to the first direction, with a repeating pattern. Auxiliary sealed membrane contains a set of tank belts (21) parallel to the first direction. A size of the repeating pattern of auxiliary rows (A, B, C) is an integer multiple of a size of tank belt (21) in the second direction. Main insulating barrier (5) contains a set of main rows parallel to the first direction. Main sealed membrane has first corrugations (56) parallel to the first direction and spaced apart from each other with first regular interval (58), wherein the size of the repeating pattern of main rows is an integer multiple of mentioned first regular interval (58).

EFFECT: creation of a tank resistant to accidental impacts and other stresses arising, for example, due to heat compression, cargo movements and/or deformation of a vessel beam at sea.
