Evaluation of Ship-Diversion Induced Emergency on Port Traffic Volumes

The worst ice blockages along the Yellow Sea coast and Bohai Sea had severe effects on maritime shipping, oil and gas mining and farming activities in the winter of 2009 and 2010. Ice blockages made some small ships divert to neighboring ports, which also affected these ports' operations. To evaluate the effect of ship-diversion induced emergency on port traffic, we propose a simulation model considering ship-diversion induced emergency, port transportation and operations. Then we carry out simulation experiments on a container terminal in Dalian Port. The experiment results show that ship-diversion induced emergency increased the peak hourly traffic volume, average daily traffic and thirtieth hourly volume, which provides a basis for port traffic planning and organization.
