Patent ID: 8235242

Claim:
An anti-sloshing LNG cargo tank, having a first barrier for preventing leakage of a cryogenic LNG, and a second barrier and an insulation pad provided to supplement the first barrier in combination with an LNG carrier body having an inner wall, the anti-sloshing LNG cargo tank comprising: an anti-sloshing bulkhead for partitioning a space in the LNG cargo tank into a plurality of spaces to reduce a sloshing phenomenon of the LNG that moves in the LNG cargo tank; and a stool part united at a first surface of the stool part to the inner wall of the LNG carrier body and united at a second surface of the stool part to the anti-sloshing bulkhead to fasten the anti-sloshing bulkhead to the inner wall of the LNG cargo tank, the stool part being coupled to the first barrier and the second barrier and having the insulation pad therein, thus preventing the cryogenic LNG from leaking towards the inner wall of the LNG carrier body or from exchanging heat with the inner wall of the LNG carrier body. wherein the stool part comprises: a first parallel member united with an edge of the anti-sloshing bulkhead; a second parallel member disposed below the first parallel member; a first support member connecting one edge of the first parallel member to one edge of the second parallel member and a second support member connecting the other edge of the first parallel member to the other edge of the second parallel member, the first and the second support member extending to the inner wall of the LNG cargo tank; first connection members extending from the first and the second support member respectively, to the first barrier, the first connection members being united with the first barrier; and second connection members extending from the first and the second support member, respectively, to the second barrier, the second connection members being united with the second barrier, wherein a plurality of insulation pads are provided on or under the second parallel member, and wherein said one edge of the second parallel member is connected to the first support member and said other edge of the second parallel member is connected to the second support member so that the second parallel member is parallel to the first parallel member.
