According to the present invention, a carrier having an outer door structure comprises: a mooring device; a hull having an opening where the mooring device is introduced and discharged; and an outer door selectively opening and closing the opening. The present invention is capable of selectively opening and closing the opening for the mooring device so as to significantly reduce air resistance due to the opening. Therefore, according to the present invention, the carrier can reduce fuel consumption. Moreover, according to the present invention, the present invention can prevent seawater from being introduced through the opening so as to minimize corrosion due to introduction of seawater. |
