Abstract
The size of container ships and bulk carriers have been getting larger and larger. Enlargement of ship size brings about reduction in the shipping cost. However, at the same time, it requires development of port facilities. Above all, the dredging of fairway is needed and that requires a lot of expense. In fairway planning for new-comer ship, it is necessary to reproduce the maneuvering motion of design ship and to consider various elements including weather and sea conditions around fairway. Based on this background, this study enabled the fairway planning for mega container ship and bulk carrier.
