Abstract

The present invention relates to a liquefied gas carrier having a width of less than 32.3 m to pass through the old Panama Canal, which includes a liquefied gas tank having a liquefied gas storage capacity of 70K or more, preferably 78.7K.

First claim

The invention claimed is:

1. A liquefied gas carrier having a width of less than 32.3 m to pass through the old Panama Canal,
having a liquefied gas storage capacity of less than 70K cubic meters and including a plurality of liquified gas tanks;
a body including a lower part having a bottom and a lower end of each of the liquefied gas tanks, an upper part having an upper deck and an upper end of each of the liquefied gas tanks, and a central part provided between the upper part and the lower part and having vertical left and right sides;
a manifold installed at the upper deck for loading or unloading liquefied gas; and
a drip tray provided downward from a connection end of the manifold on the upper deck,
wherein a total height of the body is increased by vertically extending the central part to upwardly move the manifold and the upper part, so that a liquefied gas storage capacity of less than 70K cubic meters,
wherein an outside of the upper deck where the drip tray is placed is inclined more downwardly than an inside thereof, and
wherein a height of the central part is greater than a sum of a height of the upper part and a height of the lower part.

2. The liquefied gas carrier of claim 1 ,
wherein the height of the body is 22 m to 23.5 m.

3. The liquefied gas carrier of claim 1 ,
wherein a shell of the body is provided in a single hull.

4. The liquefied gas carrier of claim 1 , wherein the liquefied gas tanks include a first liquefied gas tank disposed at a bow, and
wherein the first liquefied gas tank has at least two bending parts.

5. The liquefied gas carrier of claim 1 , wherein each of the liquefied gas tanks includes an upper part, a central part, and a lower part, and
wherein a vertical length of the central part of each of the liquefied gas tank is formed to further extend than that of a central part of a liquefied gas tank of a liquefied gas carrier having a liquefied gas storage capacity of less than 70K cubic meters.

6. The liquefied gas carrier of claim 5 , wherein vertical lengths of the upper part and the lower part of each liquefied gas tank are formed equal to those of an upper part and a lower part of a liquefied gas tank of a liquefied gas carrier having a liquefied gas storage capacity of less than 70K cubic meters.

7. The liquefied gas carrier of claim 1 ,
wherein each of the liquefied gas tanks is disposed to be spaced apart from a shell of the body at 1.4 m or more.
