PROBLEM TO BE SOLVED: To improve the navigation efficiency, that is, the economic performance in a ship having a cargo zone and an engine zone by solving the problems causing the poor efficiency, that only one cargo zone can be pushed in a pusher barge ship applying a cargo zone pushing system, and that a towing ship tows the barge by using a rope or holding the same, and a large amount of barges can not be navigated. SOLUTION: The economic performance of a ship can be improved by forming a cargo zone by integrally connecting plural container-like cargo zones, and navigating the same by an engine zone like a freight train. That is, by leaving each cargo zone at each port, the loading and unloading time can be shortened and the service can be improved, that is, the navigating efficiency and the economical performance can be improved. In addition thereto, a structure can be simplified. In particular, as each cargo zone can be easily separated from the others even it is damaged, the ship can be prevented from totally abandoned, and the safety can be ensured.
