For offering the information to judge whether or not it can make the cargo handling safe, to berth master, we developed the “support system for judgment of cargo handling”. This system estimates waves, which include long-period waves, and moored ship motions at the berth from wave forecast at offshore. This system estimates waves, long-period waves and moored ship motions at the berth from wave forecasting at offshore. In this system, correlative equation estimated from wave observation of long term is used for calculation of waves and long-period waves at the berth. The database calculated by ship motion analysis is used for estimation ship motions of moored vessel. This system was used experimentally at the coal berth in HITACHI-NAKA Port from September, 2003. When the system was used in 28 coal ships which entered port during examination periods of one year, accuracy of the judgment was about 97%. But threat score by this system was about 30%, then will be wanted to improve more. Already, this system is using to prevent troubles of emergency departure from the port and cutting rope beforehand.
