Description
본 발명은 부유식 구조물에 관한 것이다.The present invention relates to a floating structure.
액화천연가스(Liquefied Natural Gas, 이하 "LNG"라 함)는 메탄(methane)을 주성분으로 하는 천연가스(Natural Gas, 이하 "NG"라 함)를 약 -162로 냉각해서 액화시킴으로써 얻을 수 있는 무색 투명한 액체로서, NG와 비교해 약 1/600 정도의 부피를 갖는다. 따라서, NG의 이송 시 LNG로 액화시켜 이송할 경우 매우 효율적으로 이송할 수 있으며, 일 예로 LNG를 해상으로 수송(운반)할 수 있는 LNG 운반선이 사용되고 있다.Liquefied Natural Gas (LNG) is a colorless product that can be obtained by liquefying and cooling natural gas (NNG) based on methane to about -162. Clear liquid with a volume of about 1/600 as compared to NG. Therefore, when liquefied and transported to LNG during the transfer of NG can be very efficiently transported, for example, an LNG carrier that can transport (transport) LNG to the sea is used.
최근에는 해상에서 NG를 채취하여 액화한 후 저장할 수 있는 LNG 부유식 생산 저장 설비(LNG Floating, Production, Storage and Offloading, 이하 "LNG FPSO"라 함)가 사용되고 있다. Recently, LNG floating production and storage facilities (LNG FPSOs), which can collect and liquefy and store NG at sea, are used.
LNG FPSO는 해상의 특정 지점에 계류되어, 해저의 가스정으로부터 NG를 채취하여 액화한 후 저장탱크에 저장한다. LNG FPSO에 저장된 LNG는 LNG 운반선으로 옮겨져 목적지로 이송될 수 있다.The LNG FPSO is moored at a specific point on the sea, collects NG from the well of the seabed and liquefies it and stores it in a storage tank. LNG stored in LNG FPSOs can be transported to LNG carriers and delivered to their destinations.
이때, LNG FPSO에 저장된 LNG는 LNG 운반선이 LNG FPSO에 계류된 상태에서 LNG 운반선으로 이동된다. 이를 위해, LNG FPSO에는 로딩암(loading arm)이 설치되고, LNG 운반선에는 로딩 암에 대응되는 매니폴드(manifold)가 설치될 수 있으며, 로딩암이 매니폴드에 연결되어 LNG를 LNG 운반선으로 이송할 수 있다.At this time, LNG stored in the LNG FPSO is moved to the LNG carrier in a state in which the LNG carrier is moored to the LNG FPSO. To this end, a loading arm may be installed in the LNG FPSO, and a manifold corresponding to the loading arm may be installed in the LNG carrier, and the loading arm may be connected to the manifold to transfer LNG to the LNG carrier. Can be.
하지만, LNG의 이송은 LNG FPSO와 LNG 운반선이 모두 해상에 부유한 상태에서 이뤄진다. 이때, LNG FPSO와 LNG 운반선은 바람, 파도 등 해상의 조건에 따라 독립적으로 움직이게 된다. 즉, 주변 환경에 의해 LNG FPSO와 LNG 운반선은 서로 다른 운동 응답을 보이게 되며, 그에 따라 과도한 수직 방향 상대 운동이 발생된다. 이에 의해, LNG FPSO의 로딩암을 LNG 운반선의 매니폴드에 연결하는 것이 매우 어려우며, 연결 부분에 충격이 가해지거나 결합이 느슨해지는 등의 문제가 있다.However, the transfer of LNG takes place with both the LNG FPSO and the LNG Carrier suspended at sea. At this time, the LNG FPSO and LNG carrier will move independently according to the sea conditions such as wind, waves. That is, the LNG FPSO and the LNG Carrier show different movement responses due to the surrounding environment, resulting in excessive vertical relative motion. As a result, it is very difficult to connect the loading arm of the LNG FPSO to the manifold of the LNG carrier, and there is a problem such that an impact is applied to the connecting portion or the coupling is loose.
