Lng carrier having lng loading/unloading system

The present invention relates to a liquefied natural gas carrier having a liquefied gas loading / unloading system, comprising: an STL apparatus installed in a carrier to flow in and out natural gas, and a liquefied apparatus for liquefying natural gas introduced through the STL apparatus in a cryogenic state; At least one independent cargo hold installed on the carrier to store or liquefy the liquefied gas liquefied by the liquefier and one or more membrane cargo hold installed on the carrier in series with the independent cargo hold; And a vaporization device for vaporizing the liquefied gas stored in the independent cargo hold. Therefore, according to the present invention, the membrane-shaped cargo hold and the independent cargo hold are mixed, and the loading / unloading of the liquefied gas is performed through the independent cargo hold of the mixed cargo hold, thereby minimizing the effect of sloshing from the independent cargo hold, thereby preventing safety accidents. The risk can be prevented in advance, and especially when the bow side of an independent cargo hold having excellent structural strength is satisfied, the operating conditions of the polar region can also be satisfied.
