LNG -- Fixed LNG Production Storage and Offloading Unit for Nearshore

摘要

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).
