Anti-sloshing structure for lng cargo tank

Abstract

The present invention relates to anti-sloshing LNG cargo tanks to mitigate a sloshing phenomenon. The anti-sloshing LNG cargo tank having a first barrier for preventing leakage of a cryogenic LNG, a second barrier and an insulation pad provided to supplement the first barrier, includes: an anti-sloshing bulkhead for partitioning a space in the LNG cargo tank into a plurality of spaces to reduce asloshing phenomenon of the LNG that moves in the LNG cargo tank; and a stool part united at a first surface thereof to an inner wall of an LNG carrier body and united at a second surface thereof to the anti-sloshing bulkhead to fasten the anti-sloshing bulkhead to the inner wall of the LNG cargo tank. The stool part is 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.

Description

technical field [0001] The present invention relates generally to anti-slosh LNG (liquefied natural gas) cargo tanks, and more particularly to anti-slosh LNG cargo tanks comprising anti-slosh bulkheads which divide the space in the LNG cargo tank into two Parts, namely the left space and the right space, the support part fixes the anti-sway bulkhead to the inner wall of the LNG cargo tank, thereby reducing the sloshing phenomenon of LNG moving left and right in the LNG cargo tank. Background technique [0002] Generally, in an LNG carrier, which stores low-temperature (approximately -163°C) LNG in an LNG cargo tank and transports the LNG, considering the problem of brittle fracture of the carrier body due to the low temperature of LNG, the cargo tank must have a special structure. The term "special structure" refers to a structure that insulates or insulates cryogenic LNG from the structural members of the carrier body or cargo hold. Generally, as a special structure, a me...
