Risk Degree of Ship-bridge Collision based on Theory of Ship Collision Avoidance

Abstract

Bridges have played an integral role in the development of economy and progress of human society, which facilitate transportation and promote regional economic development. However, a large number of bridges for sea-crossing or river-crossing have impeded the water transportation to varying degrees, and then one part of bridges are confronted with higher risk of ship-bridge collision. There are many ship-bridge collision accidents in the world in recent decades, which caused huge casualties and property losses. This paper proposes the model of risk degree for ship-bridge collision based on the theory of ship collision avoidance, as one parts of the system of active warning of ship-bridge collision avoidance, which can show the index of dynamic risk degree for vessels passing through bridge area. The index of ship-bridge collision can make more efficiency for the system of active warning of ship-bridge collision avoidance, which can ensure safety for vessels and bridges. The verification results show the application possibility of the model in practice.
