Research On How To Prevent Ship From Colliding Feiyun River Bridge Based On Fault Tree Analysis

With the rapid development of economy and advancement of science and technology, the number, length and span of bridges on navigable waters are growing fast, which helps facilitating land transport greatly. However, those bridges are also exposed to higher risk of collision, since their width and height restrict ships’ maneuverability, especially in case of emergency and distress. Feiyun River Bridge, for example, as the traffic artery responsible for communication between the two banks, transport of cargoes and boosting of economic development, brings inconvenience to ships’navigation as well. Accidents and dangers have been witnessed since construction of this bridge, resulting in significant economic loss and negative social effect. This paper raises countermeasures to prevent ships from colliding Feiyun River Bridge based on fault tree analysis.Firstly, the paper introduces status quo of research on risk management of ship’s collision to bridge at home and abroad, analyzing physical conditions including wind, current, tide and depth of Feiyun River waters as well as navigation conditions such as distribution of berths and traffic flow of ships. Secondly, through in-depth analysis of typical case of collision from ships to the Feiyun River Bridge, it summarizes characteristics, causes and laws of such accidents and identifies risk factors of the collisions. Then, based on the fault tree analysis, the paper concludes the major risk factors:distance between ship and bridge, wind, tide, machinery failure, human error and depth of water. Lastly, this paper provides risk management measures to control the navigation safety of Feiyun River Bridge.
