The utility model discloses a jiang hai type LNG carrier that goes directly, the ship type of this transport ship is equipped with C type fluid reservoir cabin for the through type of jiang hai, in the regional pair shell double bottom structures that adopt in C type fluid reservoir cabin to by watertight bulkhead a plurality of ballast tanks of share and empty cabin the top in C type fluid reservoir cabin is equipped with the continuous turtleback of one deck individual layer, and all superstructure, bridge, cabin and propulsion system all set up at the ship stern, and the ship bow is equipped with the forecastle and the bow side pushes away. The utility model discloses a structure in C type fluid reservoir cabin is provided in the through type transport ship of jiang hai, can changing the outfit of seagoing vessel and river ship needn't be carried out with the littoral accepting station of liquefied natural gas from marine directly transportation to changjiang river middle reaches area, the haulage time weak point, the cost of transportation hangs down. And use LNG as fuel propulsion system's fuel, has economic energy-conservation, the benefit is obvious and the characteristics of emission environmental protection.
