Abstract
While very large bulk carriers are built in order to respond to the rapid growth of demand by developing countries and the Panama Canal Expansion, an initiative called international strategic port policy has been implemented. However, planning method of navigation channel design for bulk carriers under reduced draft has not been developed. Based on the above, as a first step toward the future development of such planning method, this paper is aiming at analyzing vessel motions under reduced draft, by applying the detailed designing methods adopted in the 2007 Technical Standard of Port Facilities.
