Description

독립형 저장탱크의 단열시스템 {INSULATION SYSTEM OF INDEPENDENT TYPE CARGO TANK}Insulation system of independent storage tank {INSULATION SYSTEM OF INDEPENDENT TYPE CARGO TANK}

본 발명은, 독립형 저장탱크의 단열시스템에 관한 것으로서, 보다 상세하게는, 극저온 상황에서 발생하는 단열 패널의 열수축 혹은 열변형의 중심에 누수용 배관을 마련하여 단열 패널의 단층 다층 구성과 무관하게 패널 내부 균열 및 파손 발생 우려를 최소화 할 수 있는 독립형 저장탱크의 단열시스템에 관한 것이다.The present invention relates to a thermal insulation system for an independent storage tank, and more particularly, by providing a leak pipe at the center of heat shrinkage or thermal deformation of an insulation panel that occurs in a cryogenic situation, regardless of the single-layer multi-layer configuration of the insulation panel. It relates to an insulation system of an independent storage tank that can minimize the risk of occurrence of internal cracks and damage.

LNG 운반선은 화물창(Cargo Containment System) 형식에 따라 크게 독립된 탱크를 갖춘 형식과 선체 내에 멤브레인 화물창을 만든 형식으로 분류된다.According to the cargo containment system type, LNG carriers are classified into a type with a largely independent tank and a type with a membrane cargo hold inside the hull.

독립탱크형에는 구형인 모스(MOSS)와 각형인 SPB가 있고, 멤브레인형에는 GT-96, Mark-Ⅲ, [0003] 그리고 CS1 등이 있다.Independent tank type has a spherical Moss (MOSS) and a prismatic SPB, and the membrane type has GT-96, Mark-Ⅲ, and CS1.

한편, 독립탱크형은 IMO IGC code 기준으로 type A, type B, type C로 나뉘고, 극저온 액체화물을 보관하기 위한 단열 및 누수(leakage)에 대비할 수 있는 설계를 요한다.On the other hand, the independent tank type is divided into type A, type B, and type C based on the IMO IGC code, and requires a design that can prepare for insulation and leakage for storing cryogenic liquid cargo.

일반적으로 가장 많이 사용되는 type B의 독립탱크형은 알루미늄 합금이나 SUS 및 9% 니켈 등 저온에 강한 합금으로 제조되는 탱크 몸체에 폴리우레탄과 같은 비교적 단단한 단열 패널을 부착시켜 만들어지며, 선체의 내부 바닥에 배열되는 복수의 탱크 지지체 상에 독립적으로 놓여진다.Independent tank type of type B, which is generally used the most, is made by attaching a relatively hard insulation panel such as polyurethane to the tank body made of aluminum alloy or alloy resistant to low temperatures such as SUS and 9% nickel, and the inner bottom of the hull. independently placed on a plurality of tank supports arranged in

이러한 type B의 독립탱크형 화물창은 단열 및 누수를 대비하여 IGC code 기준에 따라 단열시스템을 구성하여야 한다. type B의 독립탱크형 화물창의 단열시스템은, 탱크 구조물에 해당되는 1차 방벽과, 탱크의 하부에 부분적으로 구성되는 단열재와 누수받이(drip tray)를 포함하는 2차 방벽으로 구성된다.For this type B independent tank type cargo hold, an insulation system should be constructed in accordance with IGC code standards in preparation for insulation and leakage. Insulation system of type B independent tank type cargo hold is composed of a primary barrier corresponding to the tank structure and a secondary barrier including an insulating material and a drip tray partially composed of the lower part of the tank.

누수받이는 LNG가 누출될 경우, 누출된 LNG를 임시로 모아두는 저장소 역할을 하게 되며, 누출된 LNG는 탱크 하부 단열시스템에 구비된 누수용 배관을 통해 누수받이로 모이게 된다.In case the LNG leaks, the leaking gutter serves as a storage for temporarily storing the leaked LNG, and the leaked LNG is collected in the leaking gutter through the leak pipe provided in the insulation system under the tank.

기존 누수용 배관의 경우 단열패널에 두께방향으로 구멍을 내고 배관을 설치하도록 되어 있으나, 극저온 환경 및 LNG 누수에 환경을 고려한 설계가 미흡한 상황이다.In the case of the existing leak pipe, a hole is made in the insulation panel in the thickness direction and the pipe is installed, but the design considering the environment for cryogenic environment and LNG leakage is insufficient.

일반적으로 독립형 탱크(10)의 단열패널(20)은 블록 단위로 탱크에 고정되며 단층 혹은 다층의 단열블록으로 구성된다. 누수용 배관(30)이 설치되는 하부 단열 패널의 경우, 도 1에 도시된 바와 같이, 단열 패널을 탱크에 고정시키기 위한 패널 고정부(40)는 패널의 중앙에 배치되어 있는 것에 비해, 누수용 배관(30)은 패널의 중앙으로부터 일측으로 치우쳐 있는 위치에 배치된다.In general, the insulation panel 20 of the independent tank 10 is fixed to the tank in block units and is composed of a single-layer or multi-layer insulation block. In the case of the lower heat insulating panel in which the leak pipe 30 is installed, as shown in FIG. 1 , the panel fixing part 40 for fixing the heat insulating panel to the tank is disposed in the center of the panel, but for water leakage The pipe 30 is disposed at a position biased toward one side from the center of the panel.

이와 같이, 패널 고정부(40)가 설치된 단열패널(20)의 중앙위치로부터 치우친 위치에 누수용 배관(30)이 위치하게 될 경우, 극저온 운항 상황에서 단열패널(20)의 고정점을 중심으로 발생하는 열수축 및 열변형(도 1에 화살표로 표시됨)에 의해 패널 내부 균열 및 파손 발생 우려가 있으며 단열시스템이 다층으로 구성될 경우 상기 현상이 더욱 심해지므로 이에 대한 개선책이 요구된다.In this way, when the pipe 30 for water leakage is located at a position biased from the central position of the insulation panel 20 in which the panel fixing part 40 is installed, the fixing point of the insulation panel 20 in the cryogenic operating situation is the center. There is a risk of cracking and damage inside the panel due to the generated heat shrinkage and thermal deformation (indicated by arrows in FIG. 1 ), and when the insulation system is composed of multiple layers, the above phenomenon becomes more severe, so improvement measures are required.
