Study On The Index System Of Human Factors Involved In Ro-Ro Shipping Safety In The Three Gorges Reservoir Waterway

The Three Gorges Project draws attention of the world and is one of the biggest reservoir areas. As the construction of the Three Gorges reservoir area, the navigation dimensions are increased and the widths of channels are generally above 200 meters. Thanks to the completion of the project construction, the navigation channel conditions are improved and water transport is improved. Meanwhile, there are more branches of navigation channel and the ship density increases; there are more fog days and irregular big fog; geographic disasters happen frequently. All the above elements attribute to the high risk of the Three Gorges reservoir areas. Conforming to the requirements of the market of long-distance heavy-load truck transport, Ro-Ro transport develops rapidly. Since 2003 when the Three Gorges reservoir area is established, Ro-Ro accidents happen each year and most of which are related to human factors. Ro-Ro ships are generally used to transport cars, thus in the event of an accident, human life and properties will suffer great loss. Therefore, the safety of Ro-Ro transport is a non-ignorable issue. The discussion and analysis on human factors will help to examine and exclude the risks of Ro-Ro ships transportation and raise the safety level.Firstly, based on the accidents statistics in the Three Gorges reservoir area, the thesis analyzes the relevance between Ro-Ro accidents and human factors. The statistics show that the proportion of accidents caused by the inappropriate operation and rules violation is 70.2%; the proportion of accidents caused by human factors is 64.3%.Secondly, the human factors involved in Ro-Ro ship transportation are identified on the basis of MMEM theory. Then the human factors are analyzed based on Reason model and some cases.Thirdly, according to the SHEL model principle, the Ro-Ro ship transportation system is a complex whole composed by human, hardware, software and environment. In this thesis, the risk factors in Ro-Ro accidents are divided into five sub-systems and build a human factor index system of the Three Gorges Ro-Ro ship transportation. The five interface elements are:human-human interface element, human-hardware interface element, human-software interface element and human-environment interface element. The second-class and third-class indexes in the five subsystems are also established.Fourthly, the method of fuzzy comprehensive analysis is applied to calculate the elements in the system. One Ro-Ro is chosen to verify the analysis and the results are accordance with the real situation.Finally, suggestions on the safety of Ro-Ro ship transportation in the Three Gorges reservoir areas are proposed from the four aspects:cultivating qualified ship crew, managing the loading safety of Ro-Ro ships, improving the working and living environment and management factors.
