Abstract

Safety is very important as ships enter and depart from harbours. Ship motions were successfully observed in swells in a previous study, and difficulties were shown to occur during the berthing operation inside the harbour as well as at the harbour entrance. In this study, numerical simulations of ship motions in swells during entrance and departure are recreated for the first time. The accuracy was sufficient for modeling observed ship motions." Moreover, it will be necessary to define the evaluation parameters of the berthing operation. It is constructed and as the "Difficulty of Berthing Function" for ships. The function can be used to quantitatively evaluate the operational difficulty, which should be considered when evaluating harbour tranquility.
