The present invention relates to a coastal refining processing shipment facility for onshore LNG export and, more particularly, to a coast-fixed LNG production, storage, and unloading facility with a novel gravity-based structure. The coast-fixed LNG production, storage, and unloading facility according to the present invention includes an outside steel caisson (110) configured by a steel plate being formed in a box shape having a side surface and a bottom surface, the bottom surface being seated on a seating surface (50) provided on a coastal seabed bottom; an inside steel caisson (120) configured by a steel plate being formed in a box shape having a side surface and a bottom surface, providing a liquefied gas accommodating space (130) therein, and installed inside the outside steel caisson (110) with at least a gap between the side surface and the bottom surface; an upper deck (140) installed by the upper ends of the outside steel caisson (110) and the inside steel caisson (120) being blocked; a waterproof insulation board wall (190) installed on the inside surfaces of the inside steel caisson (120) and the upper deck (140) and insulating accommodated liquefied gas from the outside; a liquefied gas production process facility (150) and an unloading facility (160) mounted on the upper deck (140); and a weight (200) filling the space formed by the gap between the outside steel caisson (110) and the inside steel caisson (120) and providing gravity and immovably fixed after sunk to the seating surface (50).

    본 발명은 육상 LNG 수출용의 연안 정제 처리 출하시설에 관한 것으로서, 더욱 상세하게는 새로운 중력 기반 구조의 연안 고정형 LNG 생산-저장-하역 설비를 개시한다. 본 발명에 따른 연안 고정형 LNG 생산-저장-하역 설비는, 강판을 측면과 저면이 있는 상자 모양으로 형성하여 구성되며, 저면이 연안 해저 바닥에 마련한 안착면(50)에 안착되는 외측 강재 케이슨(110); 강판을 측면과 저면이 있는 상자 모양으로 형성하여 구성하여 내부에 액화가스 수용공간(130)을 제공하며, 상기 외측 강재 케이슨(110)의 내측에 적어도 측면과 저면 사이의 간격을 띄워 설치되는 내측 강재 케이슨(120); 상기 외측 강재 케이슨(110)과 내측 강재 케이슨(120)의 상단을 막아 설치되는 상갑판(140); 상기 내측 강재 케이슨(120) 및 상기 상갑판(140)의 내측면에 설치되어 수용된 액화가스를 외부와 단열하는 방수형 단열판벽(190); 상기 상갑판(140) 위에 탑재되는 액화가스 생산용 공정설비(150) 및 하역설비(160); 상기 외측 강재 케이슨(110)과 내측 강재 케이슨(120)의 간격에 의해 형성된 공간에 채워져서 중력을 제공하여 함으로써 상기 안착면(50)에 가라앉혀 움직이지 못하게 고정하는 중량체(200); 를 구비한다.
