An insulation structure of a membrane type storage tank is disclosed. The membrane type storage tank includes a secondary insulation wall comprising a plurality of secondary insulation panels; a primary insulation wall which comprises a plurality of primary insulation panels, and which is disposed at the upper part of the secondary insulation wall; and a plurality of fixing devices provided at the upper parts of the secondary insulation panels to be coupled with the primary insulation panels, wherein the plurality of fixing devices are arranged on the center line of the secondary insulation panels in a width direction so that the movement of the fixing devices in the width direction is prevented, and the plurality of fixing devices are arranged to be spaced at equal intervals with respect to the longitudinal direction of the secondary insulation panels.

Insulation structure of membrane type storage tank

A heat insulation structure for corner parts of a liquefied natural gas (LNG) storage tank includes a secondary insulation wall arranged on an inner wall of a hull, a secondary sealing wall disposed on the secondary insulation wall, a primary insulation wall arranged on the secondary sealing wall, and a primary sealing wall disposed on the primary insulation wall. The heat insulation structure includes a corner assembly finishing an edge of the primary sealing wall at a corner part of the storage tank to complete sealing of the storage tank. The corner assembly includes an endcap sheet finishing each of four corners of the primary sealing wall provided to each surface of the storage tank to seal the four corners. The endcap sheet includes an endcap corrugation and an elongated corrugation extending in a direction perpendicular to a direction in which the endcap corrugation extends.

Heat insulation structure for corner parts of liquefied natural gas storage tank

In a membrane type heat insulation system for a cryogenic liquefied gas carrier cargo tank and a liquefied gas fuel container, a secondary heat insulation layer comprises a plurality of panels which are stacked in multiple layers while each pair of upper and lower panels is arranged to intersect each other, whereby heat loss which may occur in the gap between the panels can be minimized and deformation due to a temperature difference can be minimized.

Membrane type insulation system for cryogenic liquefied gas carrier cargo tank and liquefied gas fuel container

Disclosed is a membrane type insulation system for LNG carrier cargo tank and liquefied gas fuel container wherein a corrugation finishing membrane formed of Invar steel is welded to a secondary membrane connecting portion or a primary membrane connecting portion in order to seal corrugations at a corner portion of a cargo tank in a structure wherein at least one of a primary membrane and a secondary membrane is formed of an SUS material having corrugations, thereby improving work efficiency while reducing manufacturing costs through elimination of a separate angled piece for connection between corrugations on adjacent walls at the corner portion.

Membrane type insulation system for cryogenic LNG carrier cargo tank and liquefied gas fuel container

A liquefied gas storage tank having insulation parts and a method for arranging the insulation parts are disclosed. Disclosed are the liquefied gas storage tank having the insulation parts and the method for arranging the insulation parts, the liquefied gas storage tank being capable of improving durability against the impact generated by liquefied gas since insulation panels, which are arranged in the insulating parts for the liquefied gas storage tank, have different densities according to: a load due to the mass of the liquefied gas stored in the liquefied gas storage tank; and the impact generated by sloshing.

Liquefied gas storage tank having insulation parts and method for arranging insulation parts

Provided are an LNG storage container with an inner shell, which is capable of efficiently storing LNG or pressurized LNG (PLNG) pressurized at a predetermined pressure and supplying the LNG or PLNG to a consumption place, and capable of reducing manufacturing costs by minimizing the use of a metal having excellent low temperature characteristic, and a method for manufacturing the same. The LNG storage container includes: an inner shell configured to store LNG inside; an outer shell configured to enclose the outside of the inner shell such that a space is formed between the inner shell and the outer shell; a support installed in the space between the inner shell and the outer shell to support the inner shell and the outer shell; and a heat insulation layer part installed in the space between the inner shell and the outer shell and configured to reduce a heat transfer.
