MULTI MEGA VESSEL COUPLED WITH SEGMENT VESSELS

摘要

PURPOSE: A composite ship is provided to selectively operate according to the type of unit ships, and to elastically operate the number of the ships according to the amount of cargo. CONSTITUTION: A composite ship comprises multiple unit ships(110-150) and coupling units. The unit ships include one propelling ship and at least one non-propelling ship. The coupling units are installed in the unit ships respectively in order to couple adjacent unit ships. Each coupling unit comprises a coupling protrusion, a coupling groove, and a locking pin. The coupling protrusion is protruded from one end of the unit ships, and has a vertical-through-hole in the body thereof. The coupling groove is formed in the other end of the unit ships. The coupling units are installed in one end of the unit ships, and have a through-hole vertically penetrated in a body. Other coupling protrusion of another adjacent unit ship is inserted into the coupling groove. The locking pin is installed on the top or bottom of the coupling groove, and is inserted into the through-hole of the coupling protrusion.
