Embodiment Construction

[0031] Some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0032] figure 2 is an exploded perspective view of a heat insulation structure of a cargo tank of an LNG carrier according to an embodiment of the present invention, image 3 is a sectional view of a heat insulation structure of a cargo hold of an LNG carrier according to an embodiment of the present invention.

[0033] exist figure 2 and image 3 In the structure of the cryogenic liquid cargo tank of the LNG carrier shown, the bottom heat insulation panel 110 is glued and fixed on the inner surface of the hull 100 of the LNG carrier with epoxy resin mastic 102 and stud bolts 104. A top insulation panel 120 is mounted on the bottom insulation panel 110 to form a part of the auxiliary barrier.

[0034] Here, a first metal sheet 140 is glued and installed between the bottom insulation panel 110 and the top insulation panel 120 .

[0035] The first metal ...

Abstract

Disclosed are an insulation structure of an LNG carrier cargo tank and a construction method thereof. More particularly, provided are: an insulation structure for an LNG carrier cargo tank comprising a first metal foil attached between upper and lower insulation panels, a second metal foil attached to the 1st metal foil which is placed on top of the gap between the lower insulation panels, and a top bridge panel attached to the top of the second metal foil; and a construction method of the insulation structure. The present invention can improve the sealing force in the cargo tank.

Description

technical field [0001] The present invention relates to a heat insulation structure of a cargo hold of a liquefied natural gas carrier and a method for constructing the heat insulation structure of the cargo hold of a liquefied natural gas carrier, in particular to a heat insulation structure of a cargo hold of a liquefied natural gas carrier and a method for constructing the cargo hold of a liquefied natural gas carrier that can improve all A method for the thermal insulation structure of an LNG carrier cargo hold that describes the sealing integrity of the gaps formed between the thermal insulation panels of the cargo. Background technique [0002] LNG (liquefied natural gas) generally refers to a colorless, transparent cryogenic liquid that cools natural gas (mainly methane) to about -163°C and condenses to 1 / 600 of its gas volume. [0003] With the emergence of LNG as an energy source, people have been looking for efficient transportation devices to transport LNG from a ...
