Ship for transporting a liquefied natural gas storage container

A liquefied natural gas (LNG) storage container carrier comprising:

• one or more cargo holds provided on a hull such that upper portions thereof are opened;
• a plurality of first and second upper supports installed on the cargo holds in a width direction and a length direction to partition the upper portions of the cargo holds into a plurality of openings, wherein storage containers are vertically inserted into the openings such that upper portions of the storage containers over the openings are exposed to an external environment when the storage containers are carried using the LNG storage container carrier;
• and
• a lower support installed under the cargo holds and supporting bottoms of the storage containers inserted into the openings,
• wherein the LNG is an LNG that has been pressurized and liquefied at a pressure of 13 to 25 bar and a temperature of −120 to −95° C.,
• wherein each of the storage containers includes an inner shell storing the LNG, an outer shell enclosing the inner shell, a heat insulation layer disposed between the inner shell and the outer shell, and a connection passage, between the inner shell and the heat insulation layer, providing a fluid path to make a pressure on an inside surface of the inner shell substantially equal to a pressure on an outside surface of the inner shell, and,
• wherein each of the storage containers further includes an external injection part coupled to an end part of the outer shell and having a first connecting part protruded from a bottom surface of the external injection part, and a second connecting part protruded from an end part of the inner shell, and
• wherein the first connecting part is slidably coupled to the second connecting part.

A liquefied natural gas (LNG) storage container carrier comprising:

• one or more cargo holds provided in a hull;
• a plurality of first upper supports disposed on the cargo holds and arranged in a first direction, each of the first upper supports extending in a second direction that crosses the first direction;
• a plurality of second upper supports disposed on the cargo holds and arranged in the second direction, each of the second upper supports extending in the first direction, wherein the first and second upper supports intersect to provide a plurality of openings, wherein at least one of the first and second upper supports is coupled to a stanchion, a lashing bridge, or both;
• a plurality of storage containers, wherein the plurality of storage containers are vertically inserted into the openings such that upper portions of the storage containers over the openings are exposed to an external environment when the storage containers are carried using the LNG storage container carrier;
• and
• a lower support installed under the cargo holds and supporting bottom surfaces of the storage containers inserted into the openings,
• wherein the LNG is an LNG that has been pressurized and liquefied at a pressure of 13 to 25 bar and a temperature of −120 to −95° C.,
• wherein each of the storage containers includes an inner shell storing the LNG, an outer shell enclosing the inner shell, a heat insulation layer disposed between the inner shell and the outer shell, and a connection passage, between the inner shell and the heat insulation layer, providing a fluid path to make a pressure on an inside surface of the inner shell substantially equal to a pressure on an outside surface of the inner shell, and
• wherein each of the storage containers further includes an external injection part coupled to an end part of the outer shell, a connecting part coupled to the external injection part, and a buffer part coupled between the connecting part and an end part of the inner shell and having a tube-shaped structure.
