ABSTRACT
The U.S.A. Coast Guard has reported 36000 accidents in 82 deep draft ports in ten years period in U.S.A. (Spouge 1993). Most national and international maritime organizations’ strategic targets are the management of the sea traffic at a well-designed and effective level, such that the system capacity is increased, while keeping the risks at a calculated and manageable, minimum level. As expected, in general, capacity of waterways are directly related with risk management; while traffic density and waterway
capacity increase, accident risk and pollution in the channel also increase.
