Abstract
A ballast water-free ship using a difference in the depth of the bottom shell plate between the bow/stern and the midship section and a construction method thereof. A stepped portion is formed between either the bow or the stern and the midship section, such that the depth of the bottom shell plate of either the bow or the stern differs from the depth of the bottom shell plate of the cargo containment in the midship section, so that cargo can be loaded and unloaded without ballast water operation.
