Description

검사대가 설치된 ＣＮＧ 운반선용 저장 탱크 {A CNG tank with inspection platform}Storage tank for CNC carriers with inspection platform {A CNG tank with inspection platform}

본 발명은 CNG(compressed natural gas, 이하 "CNG"라 함) 운반선용 저장 탱크에 관한 것으로서, 천연 가스를 액화시키지 않고 기체 상태로 압축한 CNG를 저장할 수 있는 저장 탱크의 검사를 위한 검사대가 구비된 저장 탱크에 관한 것이다.The present invention relates to a storage tank for a compressed natural gas (CNG) carrier, which is provided with an inspection table for inspecting a storage tank capable of storing CNG compressed in a gas state without liquefying natural gas. Relates to a storage tank.

천연가스를 운반 하는 방법에는 종래의 액화 천연 가스 운반선인 LNG 운반선이외에도 상온에서 기체 상태로 압축한 천연 가스를 해상을 통하여 운반하는 CNG 선(CNG carrier)이 있다.In addition to the LNG carrier, which is a conventional liquefied natural gas carrier, there is a CNG carrier (CNG carrier) that carries natural gas compressed into a gas state at room temperature through the sea.

이러한 CNG선은 육상으로 CNG를 운반하기 위해 막대한 투자 및 엄격한 통제가 따르는 파이프 라인을 대신하여 CNG를 해상을 통하여 용이하게 운반할 수 있다는 점에서 점차 그 중요성이 증가하고 있다.These CNG ships are increasingly important in that CNG can be easily transported by sea instead of pipelines with huge investment and strict control to transport CNG on land.

이와 같은 CNG선은 선체에 CNG를 저장하기 위한 CNG 탱크가 마련되고, 이러한 CNG 탱크는 도너츠 형태의 코젤(coselle)이 다수 개가 적층되어 서로 용접에 의해 서 고정되며, 상기 코젤의 각 내부에는 CNG가 저장되는 저장 파이프가 권선되어 있다.Such a CNG vessel is provided with a CNG tank for storing the CNG in the hull, the CNG tank is a plurality of donut-shaped cozel (coselle) are stacked and fixed by welding with each other, each inside of the cogel is CNG The storage pipe to be stored is wound.

이러한 CNG 저장 탱크는 고압의 파이프가 내장되어 있으므로 안전 사고를 예방하기 위해서 각 저장 탱크의 외면 특히 각 코젤의 연결부위를 주기적으로 검사하여야 하며, 이러한 검사를 수행하는 검사자가 이동하면서 각 저장 탱크의 외면을 확인할 수 있는 이동 통로가 저장 탱크 외면에 설치되어야 한다.Since these CNG storage tanks are equipped with high-pressure pipes, in order to prevent safety accidents, the exterior of each storage tank, especially the connection part of each cogel, should be periodically inspected. Moving passages to verify that the storage tank is to be installed on the outside.

그러나, 이러한 CNG 운반선은 최근에 개발되기 위한 것으로 이러한 검사를 위한 이동 통로에 대한 구체적인 가이드 라인이 마련되지 못하고 있다.However, such a CNG carrier is to be developed recently, and specific guidelines for a moving passage for this inspection have not been prepared.

특히, 종래의 Crude Oil Tanker 나 LNG carrier와 달리 CNG 운반선용 저장 탱크는 각 저장 탱크가 밀집된 상태로 설치되어 있으므로, 이러한 이동 통로를 설치하기에는 공간이 협소하다는 문제점이 있다.In particular, unlike the conventional Crude Oil Tanker or LNG carrier, the storage tank for the CNG carrier is installed in a dense state of each storage tank, there is a problem that the space is small to install such a moving passage.

본 발명은 상기의 문제점들을 해결하기 위해서 안출된 것으로서, 본 발명은 CNG 운반선에 밀집된 각 저장 탱크의 외면을 검사할 수 있는 검사대가 구비된 저장 탱크를 제공하는 데 그 목적이 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a storage tank having an inspection table capable of inspecting the outer surface of each storage tank concentrated in a CNG carrier.

본 발명에 따른 검사대가 설치된 CNG 운반선용 저장 탱크는 천연가스를 압축시켜 운반하는 CNG 운반선용 저장 탱크에 있어서, 도너츠 형태의 코젤이 적층된 다수 개의 저장 탱크와, 상부 코젤과 하부 코젤의 연결부 외면에 설치되어, 작업자가 이동할 수 있는 검사대로 이루어지되, 상기 검사대는 인접하는 저장 탱크의 검사대와 서로 엇갈린 위치에 설치됨을 특징으로 한다.The CNG carrier storage tank equipped with the inspection table according to the present invention is a CNG carrier storage tank for transporting the compressed natural gas, a plurality of storage tanks stacked with donut-shaped cozel, the outer surface of the connection portion of the upper and lower cozel Is installed, it is made of a test stand that can be moved by the operator, the test stand is characterized in that it is installed in a cross position with the test table of the adjacent storage tank.

여기서, 인접하는 저장 탱크 사이에는 수직 사다리가 설치되고, 상기 수직 사다리는 상기 각 저장 탱크에 설치된 검사대와 연결된 연결 통로가 설치됨을 특징으로 한다.Here, the vertical ladder is installed between the adjacent storage tank, the vertical ladder is characterized in that the connection passage connected to the inspection table installed in each storage tank is installed.

본 발명에 따른 검사대가 설치된 CNG 운반선용 저장 탱크는 인접하는 저장 탱크의 검사대와 엇갈린 위치에 검사대가 설치되어, 최소한 검사대 설치만으로도 공간이 협소한 저장 탱크 사이를 검사자가 이동하면서 전체적으로 검사할 수 있는 장점이 있다.CNG carrier storage tank is equipped with an inspection table according to the present invention has the advantage that the inspection table is installed in a position intersected with the inspection table of the adjacent storage tank, the inspection can be inspected as a whole moving between the storage tank with a narrow space at least by installing the inspection table There is this.

이하, 첨부된 도면을 참조로 하여 본 발명 검사대가 설치된 CNG 운반선용 저장 탱크 을 보다 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in more detail the storage tank for CNG carrier ship of the present invention inspection stand.

도 1은 본 발명의 바람직한 일실시예에 따른 검사대가 설치된 CNG 운반선용 저장 탱크이며, 도 2는 도 1의 정면도이다.1 is a storage tank for a CNG carrier ship equipped with a test bench according to an embodiment of the present invention, Figure 2 is a front view of FIG.
