The invention provides a liquefied natural gas transport ship and a liquefied natural gas transport system, and relates to the technical field of oceans. The ship body comprises a double-layer bottomplate, a double-board side plate and a single-layer main deck; the double-layer bottom plate comprises a ship bottom outer plate, a ship bottom inner plate and a ship bottom rib plate; the double-board side plate comprises a board side outer plate, a board side inner plate and a board side reinforcing frame plate; the single-layer main deck comprises a deck body and a deck reinforcing structure; the ship bottom inner plate, the broad side inner plate and the deck body form a liquid tank cabin in a surrounding mode, and the deck reinforcing structure is arranged on the outer side face of the deck body. The liquefied natural gas transport system comprises the ship. The technical problems that in the prior art, the capacity of a ship body structure cabin of an LNT A-BOX type liquefied gas ship is small, the overall weight of the ship body is heavy, the top in the cabin is low, the laying of a secondary screen wall and the construction process of a supporting structure are difficult, the period is long, the cost is high, and the maintenance difficulty in the cabin is large are solved.
本发明提供液化天然气运输船舶和液化天然气运输系统,涉及海洋技术领域,该船舶的船体包括双层底板、双舷侧板和单层主甲板;双层底板包括船底外板、船底内板及船底肋板;双舷侧板包括舷侧外板、舷侧内板及舷侧加强框板;单层主甲板包括甲板本体和甲板加强结构;船底内板、舷侧内板和甲板本体之间包围形成液罐舱,甲板加强结构设置于甲板本体的外侧面。该液化天然气运输系统包括前述船舶。本发明至少缓解了现有技术中LNT A‑BOX型液化气船的船体结构舱容量较小;船体整体重量较重;舱内顶部较低,次屏壁的铺设和支撑结构施工过程难度大、周期长、成本高、舱内检修难度大的技术问题。
