Description
본 발명은 LPG저장탱크(LPG CARGO TANK) 부상(浮上)방지장치(ANTI-FLOATING CHOCK FOR LPG CARGO TANK)에 관한 것이다.The present invention relates to an LPG CARGO TANK injury prevention device (ANTI-FLOATING CHOCK FOR LPG CARGO TANK).
일반적으로 LPG운반선박의 LPG저장탱크의 구조는 선체내부에 형성된공간(HOLD SPACE, 이하 화물창구역)과, 이 공간에 소정의 간격을 두고 해수등의 공급시 뜨도록 하는 LPG저장탱크로 이루어지며,그 상방으로 갑판(upper deck)이 위치한다.In general, the structure of LPG storage tank of LPG carrier ship consists of a space (HOLD SPACE, hereinafter referred to as cargo hold area) formed inside the hull, and LPG storage tank to supply the sea water at a predetermined interval in this space, The upper deck is located above it.
이와같은 LPG저장탱크구조는 충돌등의 위험상황으로 인하여 화물창구역(HOLD SPACE)으로 해수가 침범한 경우 LPG저장탱크가 해수로 인해 부상하게 되어 그 상면에 위치한 갑판저면에 충격을 주어 파손되는 결과를 초래하게 된다.This structure of LPG storage tank is damaged when seawater invades HOLD SPACE due to dangerous situation such as collision. Will result.
종래에는 이것을 방지하기 위하여 영하 42도의 저온저장물의 팽창,수축반복으로 발생되는 열을 흡열시키면서 다른 초오크와 슬라이딩이 원활하게 일어나도록 하는 수단(WOODEN BLOCK)과 부상방지초오크(ANTI-FIOATING CHOCK)로서 해결하였다Conventionally, in order to prevent this, the heat absorbing heat generated by the expansion and contraction repetition of the low temperature storage of minus 42 degrees (WOODEN BLOCK) and the floating prevention choke (ANTI-FIOATING CHOCK) Solved as
그러나, 종래 부상방지초오크가 8각형의 탱크 위의 상부경사면(TANK UPPER SLOPE AREA)에 위치하여 시공시 각 부상방지초오크와 갑판과의 사이 간격을 일치시키기가 어려운 형상이었고, 갑판과 탱크정상부의 경사면 사이에 위치시킴으로써 저장탱크 탑재시 정확한 위치조정과 설치작업이 어려움이 발생되어 수리작업이 발생되었다.이 단점을 보완하고자 불필요한 우든블럭(WOODEN BLOCK)도 함께 적용되었다.However, the conventional anti-occupation choke is located on the tank upper slope area on the octagonal tank, so it is difficult to match the gap between each anti-occupation choke and the deck during construction. The location between the inclined surfaces of the storage tanks made it difficult to precisely adjust and install the storage tanks, resulting in repairs. To compensate for this disadvantage, unnecessary wooden blocks were also applied.
일반적으로 문제점은 상기 LPG저장탱크가 위치하는 탱크를 둘러싸는 공간(HOLD TANK SURFACE)과 탱크표면(TANK SURFACE)사이에 설치되는 부상방지 초오크는 시공시 각 부상방지초오크와 갑판과의 사이 간격을 일치시키기가 어렵고, 갑판과 탱크정상부의 경사면 사이에 위치시킴으로써 저장탱크 탑재시 정확한 위치조정과 설치작업이 어려웠다.In general, the problem is that the injury prevention choke installed between the tank (HOLD TANK SURFACE) and the tank surface (TANK SURFACE) surrounding the tank in which the LPG storage tank is located is the interval between each injury prevention choke and the deck during construction This is difficult to match and it is difficult to precisely position and install the storage tank by placing it between the deck and the slope of the tank top.
본 발명은 부상방지초오크가 대접면(COUNTER SURFACE)과 동일한 간격을 유지하도록 함으로써 본래 기능을 완벽히 수행할 수 있으며, 그 시공방법이 간단하고 정밀하게 시공할 수 있도록 하는 LPG저장탱크의 부상방지장치를 제공하는 데에 그 목적이 있다.The present invention is to prevent the injury prevention choke to maintain the same interval as the counter surface (COUNTER SURFACE) can fully perform the original function, the construction method of the LPG storage tank to prevent the injury to be installed precisely and precisely The purpose is to provide.
아울러 불필요한 우든블럭등을 제거함으로써 경제성을 높이고자 하는 데에도 그 목적이 있다.In addition, the purpose is to improve economics by removing unnecessary wooden blocks.
본 발명은 LPG저장탱크의 화물창구역내에 해수등이 침투하는 경우 갑판과의 충돌을 방지하기 위하여 LPG저장탱크의 소정위치에 부상방지장치를 함으로써 상기한 문제점들을 개선하는 데에 그 목적이 있다.The present invention has an object to improve the above problems by providing a flotation prevention device in a predetermined position of the LPG storage tank in order to prevent the collision with the deck when seawater infiltrate into the cargo hold area of the LPG storage tank.
