Description

{Secondary barrier installation structure and method}

The present invention relates to a secondary barrier installation structure and method, and more particularly, to a secondary barrier installation structure and a secondary barrier installation structure, And a barrier installation structure and method.

Natural gas is a fossil fuel containing methane as a main component and a small amount of ethane, propane, and the like, and has recently been regarded as a low-pollution energy source in various technical fields.

Natural gas is transported in a gaseous state through land or sea gas pipelines, or is transported to a remote location where it is stored in an LNG carrier in the form of liquefied natural gas (LNG). Liquefied natural gas is obtained by cooling natural gas at a cryogenic temperature (approximately -163 ° C), and its volume is reduced to approximately 1/600 of that of natural gas in a gaseous state, making it well suited for long distance transportation through the sea.

LNG RV, LNG FPSO, LNG FSRU, and other marine structures are equipped with cargo (storage tank) that can store and store liquefied natural gas. Since the boiling point of liquefied natural gas is about -163 ° C at atmospheric pressure, the liquefied natural gas hold is made of materials that can withstand extremely low temperatures such as aluminum steel, stainless steel and 35% nickel steel to safely store and store liquefied natural gas And is designed to be resistant to thermal stress and heat shrinkage, and to prevent heat penetration.

These storage tanks are classified into independent tanks and membrane types depending on whether the load of the cargo directly acts on the insulation. The membrane type storage tanks are GTT NO 96 type and TGZ MARK III type And the independent tank type storage tanks include MOSS type and IHI-SPB type.

The above NO 96 and MARK-III tank structures are described in U.S. Patent Nos. 6,035,795, 6,378,722, 5,586,513, and U.S. Patent Publication No. 2003-0000949, Korean Patent Laid-open Nos. 10-2000-0011347 and 10 -2000-0011346. Further, the structure of the independent tank type storage tank is described in Korean Patent No. 10-15063 and No. 10-305513.

Fig. 1 schematically shows a heat insulating structure of a NO 96 type storage tank.

The insulating structure of the NO 96 type storage tank is composed of a primary sealing wall 1 and a secondary sealing wall 3 made of Invar steel (36% Ni) having a thickness of 0.5 to 1.5 mm, a primary insulation wall 2 and a secondary insulation wall 4 composed of a plywood box and a perlite are alternately stacked on the inside of the hull.

In the case of the NO 96 type, since the primary sealing wall 1 and the secondary sealing wall 3 have almost the same liquid tightness and strength, the secondary sealing wall can be freely taken out for a considerable period of time at the time of leakage of the primary sealing wall. However, since the primary and secondary sealing walls are made of expensive invar steel, there is a disadvantage that the manufacturing cost is high.

Fig. 2 schematically shows a heat insulation structure of the MARK-type storage tank.

The primary insulation wall of the MARK-III type storage tank is formed by laminating the primary insulation wall 10 and the secondary insulation wall 20. The primary wall 30 provided on the primary insulation wall is made of stainless steel (SUS) And the secondary barrier 40 provided between the primary insulating wall and the secondary insulating wall is made of a triplex laminated and adhered to glass fiber and aluminum foil. In the stainless steel constituting the primary barrier 30, a corrugation is provided in order to buffer the heat shrinkage due to the low temperature of the liquefied natural gas. Since the insulation structure of the MARK-Ⅲ type storage tank is difficult to install due to the wrinkle structure and it is difficult to apply the SUS of the wrinkled structure due to the interference with the insulation wall arrangement in the secondary barrier, There is a disadvantage that the safety is lower than that of the NO 96 type sealing wall.

As a conventional technique for an LNG tank capable of storing and storing LNG that has been liquefied at a cryogenic temperature, there is a heat insulation structure of a liquefied natural gas cargo hold of Korean Patent Laid-Open No. 10-2012-0134596.

In such a conventional technique, an insulation panel corresponding to a gap insulation is installed in an insulation panel, that is, a secondary insulation panel, because there is a gap due to mounting and manufacturing tolerances and insulation is required for the insulation panel. The installation method varies greatly depending on the membrane shape of the secondary barrier.

Also, in the prior art, it is necessary to separate and install the secondary barriers and then perform welding for them because it is difficult in the actual process to install the whole without installing the secondary barrier in order to install the insulator . At this time, the time and effort required for the installation of the secondary barrier vary greatly depending on how the secondary barrier composed of a flat part and a corrugation part is separated into a certain structure and how it is welded And particularly, as the number of welding lines for integrating the secondary barrier increases, it is uneconomical. Therefore, it has been necessary to find a way to enable the economical installation of the secondary barrier by reducing the welding line of the secondary barrier while enabling the installation of the insulator corresponding to the gap insulation between the secondary insulation panels.

It is an object of the present invention to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a method of installing a heat insulating material in a gap of a secondary thermal insulating panel by minimizing a welding line for integrating a secondary wall, To reduce the time and effort required to ensure the economic efficiency.
