ＬＮＧ 운반선 화물창의 인슐레이션 구조{INSULATION STRUCTURE OF CARGO TANK OF LNG CARRIER}INSULATION STRUCTURE OF CARGO TANK OF LNG CARRIER}

본 발명은 하부 인슐레이션 패널에 2차 방벽을 부착시키기 위한 작업을 용이하도록 하는 LNG 운반선 화물창의 인슐레이션 구조에 관한 것이다.The present invention relates to an insulation structure of an LNG carrier cargo hold that facilitates work for attaching a secondary barrier to a lower insulation panel.

일반적으로, 액화천연가스(Liquefied Natural Gas, 이하 'LNG'라 함)는 메탄(methane)을 주성분으로 하는 천연가스를 -162℃로 냉각해 그 부피를 6백분의 1로 줄인 무색 투명한 초저온 액체를 말한다.In general, liquefied natural gas (LNG) is a colorless transparent cryogenic liquid whose natural gas, which is methane-based, is cooled to -162 ° C and reduced in volume to one hundredth. Say.

이러한 LNG가 에너지 자원으로 사용됨에 따라 이 가스를 에너지로 이용하기 위해서 생산기지로부터 수요지의 인수지까지 대량으로 수송할 수 있는 효율적인 운송 방안이 검토되어 왔으며, 이러한 노력의 일환으로 대량의 LNG를 해상으로 수송할 수 있는 LNG 운반선이 개발되었다.As this LNG is used as an energy resource, an efficient transportation method for transporting a large amount from the production base to the destination of the demand site has been considered in order to use this gas as energy. LNG carriers have been developed for transport.

그런데, LNG 운반선에는 초저온상태로 액화시킨 LNG를 보관 및 저장할 수 있는 화물창(Cargo)이 구비되어야 하는데, 이러한 화물창에 요구되는 조건이 매우 까다로워 많은 어려움이 있었다. 즉, LNG는 대기압 보다 높은 증기압을 가지며, 대략 -162℃ 정도의 비등 온도를 갖기 때문에, 이러한 LNG를 안전하게 보관하고 저장하 기 위해서는 이를 저장하는 화물창은 초저온에 견딜 수 있는 재료, 예를 들면 알루미늄강, 스테인리스강, 35% 니켈강 등으로 제작되어야 하며, 기타 열응력 및 열수축에 강하고, 열침입을 막을 수 있는 독특한 인슐레이션 구조로 설계되어야 했다.By the way, the LNG carrier should be provided with a cargo hold (Cargo) that can store and store the LNG liquefied in a cryogenic state, there were a lot of difficulties due to the very demanding conditions for such cargo hold. That is, since LNG has a vapor pressure higher than atmospheric pressure and has a boiling temperature of about -162 ° C, in order to safely store and store such LNG, a cargo hold storing the LNG is a material that can withstand ultra low temperatures, for example, aluminum steel. It should be made of stainless steel, 35% nickel steel, etc., and should be designed with a unique insulation structure that is resistant to other thermal stresses and heat shrinkage and prevents heat intrusion.

종래의 일 실시예에 따른 LNG 운반선의 화물창 인슐레이션 구조를 첨부된 도면을 참조하여 설명하면 다음과 같다. Referring to the accompanying drawings, the cargo hold insulation structure of the LNG carrier according to the prior art is as follows.

한편, 하부 인슐레이션 패널(10)이 서로 접하는 부위는 그 상측에 2차 방벽(30)이 접착제(31)를 사용하여 부착된다.On the other hand, the portion where the lower insulation panel 10 is in contact with each other, the secondary barrier 30 is attached to the upper side using the adhesive 31.

이와 같은, LNG 운반선의 화물창 인슐레이션 구조에서 2차 방벽(30)은 하부 인슐레이션 패널(10)에 폴리우레탄 글루 등과 같은 접착제(31)를 사용하여 부착됨으로써 화물창의 기밀성을 2차적으로 담당하게 된다.In the cargo hold insulation structure of the LNG carrier as described above, the secondary barrier 30 is attached to the lower insulation panel 10 by using an adhesive 31 such as polyurethane glue, so that the cargo hold is secondaryly sealed.

In addition, in describing the present invention, when it is determined that the detailed description of the related known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

도 2는 본 발명의 일 실시예에 따른 LNG 운반선 화물창의 인슐레이션 구조를 도시한 단면도이다. 도시된 바와 같이, 본 발명의 일 실시예에 따른 LNG 운반선 화물창의 인슐레이션 구조는 하부 인슐레이션 패널(bottom insulation pane; 110) 상에 위치하는 2차 방벽(130)과, 2차 방벽(130)을 하부 인슐레이션 패널(110)에 고정시키는 패널 접착 테이프(140)를 포함할 수 있다.Figure 2 is a cross-sectional view showing the insulation structure of the cargo hold of the LNG carrier according to an embodiment of the present invention. As shown, the insulation structure of the LNG carrier cargo hold according to an embodiment of the present invention is a secondary barrier 130, which is located on the bottom insulation panel (110) and the secondary barrier 130 is lower The panel adhesive tape 140 may be fixed to the insulation panel 110.

2차 방벽(130)은 하부 인슐레이션 패널(110)들의 인접 부위 상면에 위치하고, 일례로 서플 트리플렉스(supple triplex)가 사용될 수 있다.Secondary barrier 130 is located on the upper surface of the adjacent portion of the lower insulation panel 110, for example, a triple triplex (supple triplex) may be used.

한편, 하부 인슐레이션 패널(110)은 LNG 운반선의 선체(1) 내측면에 하부 플라이우드(bottom plywood; 111)를 매개로 하여 부착 고정되고, 다른 하부 인슐레이션 패널(110)과의 사이에 형성되는 갭(gap)에 유리섬유(112)가 삽입되며, 상면에 상부 인슐레이션 패널(top insulation panel; 120)이 부착된다. 이 때, 상부 인슐레이션 패널(120)은 상면에 상부 플라이드우드(top plywood; 121)가 부착될 수 있다.Meanwhile, the lower insulation panel 110 is attached to and fixed to the inner surface of the hull 1 of the LNG carrier via a bottom plywood 111, and a gap formed between the lower insulation panel 110 and another lower insulation panel 110. The glass fiber 112 is inserted into the gap, and a top insulation panel 120 is attached to the top surface. In this case, a top plywood 121 may be attached to the upper insulation panel 120.

패널 접착 테이프(140)는 2차 방벽(130)의 상면과 하부 인슐레이션 패널(110)의 상면에 부착됨으로써 2차 방벽(130)이 기밀성을 담당하도록 한다. 즉, 패널 접착 테이프(140)는 2차 방벽(130)의 상면 중 일부 또는 전부를 포함하여 하부 인슐레이션 패널(110)의 상면에 부착됨으로써 2차 방벽(130)이 하부 인슐레이션 패널(110)에 기밀을 유지할 수 있도록 고정되도록 한다.The panel adhesive tape 140 is attached to the upper surface of the secondary barrier 130 and the upper surface of the lower insulation panel 110 so that the secondary barrier 130 is in charge of airtightness. That is, the panel adhesive tape 140 is attached to the upper surface of the lower insulation panel 110 by including some or all of the upper surface of the secondary barrier 130 so that the secondary barrier 130 is hermetically sealed to the lower insulation panel 110. To hold it in place.

패널 접착 테이프(140)는 2차 방벽(130)이 하부 인슐레이션 패널(110)의 기밀성을 담당할 수 있도록 하기 위한 다양한 형태 및 개수로 이루어질 수 있는데, 본 실시예에서처럼 2차 방벽(130)마다 한 쌍으로 이루어져서 2차 방벽(130)의 길이방향을 따라 2차 방벽(130)의 양측을 하부 인슐레이션 패널(110)에 각각 고정시키도록 마련될 수 있다.The panel adhesive tape 140 may be formed in various shapes and numbers so that the secondary barrier 130 may be responsible for the airtightness of the lower insulation panel 110. It may be provided in pairs to fix both sides of the secondary barrier 130 along the longitudinal direction of the secondary barrier 130 to the lower insulation panel 110, respectively.

패널 접착 테이프(140)는 2차 방벽(130)과 하부 인슐레이션 패널(110)에 접착되기 위하여 일측면에 접착물질의 적층에 의해 형성되는 접착층(미도시)을 가지게 되며, 다양한 재질로 이루어지는데, 일례로 폴리에스테르 계열의 재질로 이루어질 수 있다.The panel adhesive tape 140 has an adhesive layer (not shown) formed by laminating an adhesive material on one side in order to adhere to the secondary barrier 130 and the lower insulation panel 110, and is made of various materials. For example, it may be made of a polyester-based material.

패널 접착 테이프(140)는 접착 시 2차 방벽(130)이나 하부 인슐레이션 패널(110)과의 접착 정도나 기포 형성 등과 같은 접착 불량을 외부에서 확인할 수 있도록 투명 재질로 이루어질 수 있다.The panel adhesive tape 140 may be made of a transparent material so that adhesion failure such as adhesion degree or bubble formation with the secondary barrier 130 or the lower insulation panel 110 may be confirmed from the outside.

이와 같은 구성을 가지는 본 발명에 따른 LNG 운반선 화물창의 인슐레이션 구조의 작용을 예로 들어 설명하면 다음과 같다.Referring to the action of the insulation structure of the LNG carrier cargo hold according to the present invention having such a configuration as an example as follows.

하부 인슐레이션 패널(110)들이 서로 인접하는 상면에 유리섬유(112)를 포함하는 영역을 덮도록 2차 방벽(130)을 위치시킨 다음, 패드 접착 테이프(140)를 사용하여 2차 방벽(130)을 하부 인슐레이션 패널(110)에 고정되도록 함과 아울러 이에 대한 기밀성을 부담할 수 있도록 한다.The secondary barrier 130 is positioned so that the lower insulation panels 110 cover the area including the glass fibers 112 on the upper surfaces adjacent to each other, and then the secondary barrier 130 is formed using the pad adhesive tape 140. To be fixed to the lower insulation panel 110, and also to bear the confidentiality for it.

그러므로, 2차 방벽(130)의 고정 내지 접착을 위하여 종래의 폴리우레탄 글루 등과 같은 접착제를 하부 인슐레이션 패널(110)에 도포하는 작업을 생략할 수 있도록 하여 2차 방벽(130)의 부착작업에 소요되는 인력과 시간을 최대한 단축시키도록 한다.Therefore, in order to fix or adhere the secondary barrier 130, the application of the adhesive such as polyurethane glue to the lower insulation panel 110 can be omitted so that the secondary barrier 130 can be attached. Try to minimize the manpower and time required.
