Ballast-free water vessel using the difference in depth between the bow and tail and the bottom of the vessel and its construction method

摘要

The present invention forms a step between the bow and stern and the center of the hull, and the depth of the bottom of the bow and stern is different from the depth of the bottom of the cargo hold located at the center of the hull. By doing so, the present invention relates to a non-ballast water vessel using a difference in depth between the bow and the bottom of the center and the bottom so that cargo can be loaded or moved without operation of ballast water, and a method for constructing the same.
