HEAT-INSULATING SEALED WALL OF RESERVOIR MADE OF POLYMERIC COMPOSITE MATERIALS FOR COMPRESSED NATURAL GAS Russian patent published in 2014 - IPC B63B25/16 F17C3/02 

FIELD: transport.

SUBSTANCE: heat-insulating sealed wall of reservoir for compressed natural gas consists of blocks fixed on vessel hull using mechanical fixture which blocks include primary and secondary heat-insulating panels, primary sealing layer fixed on the blocks and secondary sealing layer located between them. The blocks are interconnected using bands of sealing layers, as well as heat-insulating materials placed in gaps between blocks. Wall blocks have forming coverage from all sides made of polymeric composite materials creating enclosed volume simultaneously surrounding primary and secondary heat-insulating panels. The blocks include primary sealing layer which is made of flexible material and attached directly to panels by means of sticking primary heat-insulating panel on the outside of forming coverage with partial transition to secondary heat-insulating panel forming coverage. In this structure, gaps between block panels are closed by bands of corresponding sealing layer which bands are attached to panels by sticking on portions of primary sealing layer at panel edges.

EFFECT: lowering labour consumption during manufacturing and assembling reservoir in vessel hull, lowering reservoir mass while increasing design reliability and its heat-insulating properties.
