FORWARD SNG TANK WITH DOUBLE-INCLINED TOP Russian patent published in 2014 - IPC B63B25/16 

FIELD: transport.

SUBSTANCE: invention relates to shipbuilding and concerns vessels for compressed natural gas transportation. Invention covers vessel having load-carrying structure and sealed, heat-insulated forward tank (53) for compressed natural gas with several bulkheads (54, 55, 56, 57, 58, 59, 60, 61, 62, 63) attached to load-carrying structure. Each bulkhead contains main sealing barrier, main heat-insulating barrier, auxiliary sealing barrier and auxiliary heat-insulating barrier which are located in tandem through-thickness in direction from inner surface of forward tank to its outer surface. The first bulkhead (56) and the second bulkhead (63) among the mentioned tank bulkheads are adjacent to apex (65). The main sealing barrier of the first bulkhead contains at least one first belt (67) connected at apex with load-carrying structure by pillar. The main sealing barrier of the second bulkhead contains at least one second belt (64) connected at the mentioned apex (69) with load-carrying structure by the mentioned pillar.

EFFECT: simplification of compressed natural gas tank design, higher vessel capacity.
