SEALED AND HEAT INSULATED CARGO TANK, INTEGRATED INTO BEARING STRUCTURE Russian patent published in 2016 - IPC F17C3/02 B63B25/16 

FIELD: transportation.

SUBSTANCE: tank is intended for storage and transportation of liquefied natural gas. Tank (71) comprises a heat insulation, containing multiple adjacent insulating units (28) on bearing structure, and a seal, which includes multiple sealing metal sheets (25) located on insulating units (28) and welded to each other. Mechanical connection elements (11) pass through heat insulation at level of edges of insulating units (28) and held insulating units in support contact on bearing structure (3). Metal sheets (25) are located so that edges of metal sheets are shifted relative to edges of underlying insulating units (28). Metal sheets (25) are retained in support contact on insulating units (28) only by means of connecting elements. Mechanical connection elements are attached to metal sheets (25) at level of areas (11) fixing at distance from edges of metal sheets.

EFFECT: high reliability.
