Problems solved by technology

[0007] However, in this case, there is a disadvantage that much time and cost are required to construct the heat insulating panel system
[0008] As far as the spray insulation system is concerned, there are advantages of simple construction and low cost, but there are disadvantages that it is practically impossible to sense leakage gas and contain leakage liquid

Abstract

To provide a liquefied cargo storage tank.SOLUTION: The liquefied cargo storage tank may include: a tank body 10 to store a liquefied natural gas; a venting layer 12 surrounding the outer side of the tank body 10 and having a ventilating structure; a heat insulating layer 14 having a water-tight and airtight structure and surrounding the outer side of the venting layer 12; and a gas discharge portion 200 passing through the venting layer 12 and the heat insulating layer 14 and discharging the liquefied gas which has leaked into the venting layer 12 from the tank body 10 to the outside.SELECTED DRAWING: Figure 1

Description

technical field [0001] The present invention relates to a liquefied cargo storage tank, and more particularly to a liquefied gas cargo storage tank for storing liquefied gas such as liquefied natural gas. Background technique [0002] Generally speaking, Liquefied Natural Gas (LNG) refers to a colorless and transparent ultra-low temperature liquid whose volume is reduced to 61% by cooling natural gas with methane as its main component at -163°C . [0003] As such liquefied natural gas is used as an energy resource, a liquefied cargo ship capable of transporting liquefied cargo formed of a large amount of liquefied natural gas to the sea is developed. Such a liquefied cargo ship has a liquefied cargo storage tank capable of storing and storing liquefied natural gas liquefied in a cryogenic state. [0004] Liquefied cargo storage tanks can be divided into independent type and membrane type according to whether the load of the liquefied cargo is directly affected by the heat ...
