Delay of container services is the big problem in recent years. One of the causes is considered the concentration of calling at specific ports and terminals, which had been induced by revision of alliances.
Based on this background, this study analyzed offshore waiting time, which is the main factor of delay, in world container terminals. Waiting time of each ship was calculated by spent time from port entry to berthing by utilizing AIS data. From the result, it was revealed that offshore waiting time of each terminal linked to berth occupancy ratio, delay of berthing ship, and characteristic of schedule.
