본 발명은 액화가스 저장탱크의 지지 구조체에 관한 것이다.The present invention relates to a support structure for a liquefied gas storage tank.

액화가스, 예를 들어 액화천연가스(LNG, Liquefied Natural Gas)를 연료로 사용하는 선박 등에는 액화가스 저장탱크가 구비된다. 그 중 실린더 형상(C-type)의 액화가스 저장탱크는 갑판 상에 설치된 한 쌍의 새들(saddle)에 의해 지지되는 것이 일반적이다.A liquefied gas storage tank is provided in ships using liquefied gas, for example, liquefied natural gas (LNG) as a fuel. Among them, the cylinder-shaped (C-type) liquefied gas storage tank is generally supported by a pair of saddles installed on the deck.

종래 새들은 액화가스 저장탱크의 외주면에 직접 부착되는 형태로 이루어졌다.The conventional saddle was made in the form of being directly attached to the outer peripheral surface of the liquefied gas storage tank.

그로 인해, 종래 새들은 구조적 유연성이 떨어지고, 특정 상황에서 하중 집중이 발생할 수 있으며, 그 결과 파손 우려가 있는 문제가 있었다.For this reason, the conventional saddle has poor structural flexibility, and load concentration may occur in certain situations, and as a result, there is a problem that there is a risk of breakage.

또한, 액화가스 저장탱크는 외부로부터의 열 유입을 최소화하여 선박 운항 중 증발가스 발생을 최소화할 필요가 있는데, 종래 새들은 액화가스 저장탱크에 직접 부착되어 있어 이를 통해 열 유입량이 증가할 수 있는 문제도 있었다.In addition, the liquefied gas storage tank needs to minimize the inflow of heat from the outside to minimize the generation of boil-off gas during vessel operation. there was also

도 1은 종래 액화가스 저장탱크의 지지 구조체의 도면이다.1 is a view of a support structure of a conventional liquefied gas storage tank.

도 1을 참조하면, 종래 액화가스 저장탱크의 지지 구조체(10)는 액화가스 저장탱크(T)를 지지하는 한 쌍의 새들(11, 13)을 포함할 수 있는데, 새들(11, 13)은 상술한 것처럼 액화가스 저장탱크(T)의 외주면에 직접 부착되는 형태로 이루어져 구조적 유연성(flexibility)을 확보하기 어려운 문제 등이 있었고, 액화가스 저장탱크(T)의 여러 하중 및 움직임을 제어하기 위해 우드 블록, 부상 방지 장치(anti-floatation device) 등을 구비하였다.1, the support structure 10 of the conventional liquefied gas storage tank may include a pair of saddles 11 and 13 for supporting the liquefied gas storage tank T, the saddles 11 and 13 are As described above, there was a problem in that it was directly attached to the outer peripheral surface of the liquefied gas storage tank (T), so it was difficult to secure structural flexibility. In order to control various loads and movements of the liquefied gas storage tank (T), wood A block, an anti-floatation device, and the like were provided.

도 2는 본 발명의 일 실시 예에 따른 액화가스 저장탱크의 지지 구조체의 사시도이고, 도 3은 도 2의 단면도이고, 도 4는 도 2의 새들의 단면도이다.2 is a perspective view of a support structure of a liquefied gas storage tank according to an embodiment of the present invention, FIG. 3 is a cross-sectional view of FIG. 2, and FIG. 4 is a cross-sectional view of the saddle of FIG.

도 2 내지 도 4를 참조하면, 본 발명의 일 실시 예에 따른 액화가스 저장탱크의 지지 구조체(20)는 선박 등의 데크(D) 상에 배치되는 액화가스 저장탱크(T)의 하중을 지지하는 구조물로서, 배관부(100), 제1 새들(200) 및 제2 새들(300)을 포함할 수 있다.2 to 4, the support structure 20 of the liquefied gas storage tank according to an embodiment of the present invention supports the load of the liquefied gas storage tank (T) disposed on the deck (D) of a ship, etc. As a structure to do so, it may include a pipe part 100 , a first saddle 200 , and a second saddle 300 .

액화가스 저장탱크(T)는 극저온의 액화가스, 예를 들어 액화천연가스를 저장할 수 있고, 수평 방향으로 연장되는 실린더 또는 캡슐 형상(C-type)의 탱크일 수 있다.The liquefied gas storage tank T may store cryogenic liquefied gas, for example, liquefied natural gas, and may be a cylinder or capsule-shaped (C-type) tank extending in the horizontal direction.

배관부(100)는 액화가스 저장탱크(T)의 중심을 수평 방향으로 관통하는 메인 배관(110)을 포함할 수 있다.The pipe part 100 may include a main pipe 110 passing through the center of the liquefied gas storage tank T in the horizontal direction.

메인 배관(110)의 일단부와 타단부는 액화가스 저장탱크(T)의 외부로 노출될 수 있다.One end and the other end of the main pipe 110 may be exposed to the outside of the liquefied gas storage tank (T).

또한, 배관부(100)는 액화가스 저장탱크(T) 내에서 메인 배관(110)으로부터 분기되는 분기 배관(120)을 포함할 수 있다.In addition, the pipe part 100 may include a branch pipe 120 branched from the main pipe 110 in the liquefied gas storage tank (T).

즉, 분기 배관(120)의 일단은 메인 배관(110)에 연결될 수 있고, 분기 배관(120)의 타단은 액화가스가 분기 배관(120) 내로 유입될 수 있도록 개방된 형태일 수 있다.That is, one end of the branch pipe 120 may be connected to the main pipe 110 , and the other end of the branch pipe 120 may have an open shape so that liquefied gas can be introduced into the branch pipe 120 .

따라서, 액화가스 저장탱크(T) 내에 저장된 액화가스는 분기 배관(120) 및 메인 배관(110)을 차례로 거쳐 외부, 예를 들어 선박 엔진(미도시) 등으로 이송될 수 있다. 이를 위해, 메인 배관(110) 또는 분기 배관(120)에는 펌프(미도시)가 설치될 수 있다.Accordingly, the liquefied gas stored in the liquefied gas storage tank T may be transferred to the outside, for example, a marine engine (not shown), through the branch pipe 120 and the main pipe 110 in turn. To this end, a pump (not shown) may be installed in the main pipe 110 or the branch pipe 120 .

한편, 분기 배관(120)은 예를 들어 메인 배관(110)으로부터 하향 연장될 수 있고, 분기 배관(120)의 개방된 하단은 액화가스 저장탱크(T)의 바닥 면으로부터 이격 배치될 수 있다.On the other hand, the branch pipe 120 may extend downward from the main pipe 110, for example, and the open lower end of the branch pipe 120 may be spaced apart from the bottom surface of the liquefied gas storage tank (T).
