ESCAPING LNG COLLECTION STRUCTURE FOR LNG TANK AND MARINE STRUCTURE HAVING LNG TANK

摘要

The present invention relates to an escaping LNG collection structure for an LNG tank and a marine structure having the LNG tank. More specifically, the escaping LNG collection structure for the LNG tank is provided to secure a space required to repair or replace an insulation of the LNG tank, or arrange outfitting items by turning a sump well, which functions as a drip tray, into a hull; simplify process procedures which form a structure to store escaping LNG, and a structure discharging the escaping LNG; reduce material costs by making a hull more cheaply than separately-manufactured outfitting items; and have excellent corrosion resistance against cryogenic LNG by applying clad steel to an inner bottom plate. The escaping LNG collection structure for an LNG tank comprises a sump well formed on the inner bottom plate of a hull accommodating the LNG tank to collect LNG escaping from the LNG tank, wherein the sump well has a groove shape formed on the inner bottom plate, and a surface inclined from the upper end to the bottom surface thereof and formed on the side part thereof.;COPYRIGHT KIPO 2015
