• at least one propeller formed on the underbody to propel the hull;
• a power generation unit formed at a stern on the deck to generate electricity to be supplied to the propeller;
• a cargo space disposed nearer to a bow on the deck than the power generation unit and allowing one or more tank containers storing liquefied gas to be loaded therein;
• and
• a loading/unloading space disposed nearer to the bow on the deck than the cargo space and allowing an external conveyance to enter to load/unload the tank containers;
• and
• a fuel supply line connected between the power generation unit and at least one of the tank containers to convey liquefied gas fuel from the at least one tank container to the power generation unit.

• the passageway comprises:
• a reclosable door unit opening/closing an entryway for the external conveyance;
• a guide unit comprising at least one pair of guide modules disposed at respective transverse ends of the loading/unloading space with respect to a moving direction of the external conveyance to guide the external conveyance to the loading/unloading space;
• a positioning unit comprising a plurality of roller bearings formed inside the respective guide modules in transverse directions thereof, the plurality of roller bearings being transversely rotatable to correct a transverse position of the external conveyance;
• and
• a stop module disposed at one longitudinal end of the loading/unloading space to restrict a longitudinal position of the external conveyance.
