Study On Risk Assessment And Control Measures For Dangerous Goods Of Waterway Transportation

China is a large country for production and transportation of dangerous goods,more than95% of dangerous goods are transported to different places.A large number of chemical raw materials and products need to be distributed across the country through various means of transportation.Taking into consideration infrastructure investment,carrying capacity,transportation cost and the like,waterway transportation has become the top choice of many modes of transport,water transportation of dangerous goods has corresponding requirements for shipping companies and ships.As its multi-link factors on transport operations,the risk will make a difference accordingly.Whereas dangerous goods have its own special attributes such as explosibility,flammability and corrosivity.If a major accidents of water transport for dangerous goods happens,the economic losses and social influence will get more serious.Therefore,the safety of hazardous goods of waterway transport become the focus of all parts.Firstly,The paper gives a comprehensive review and summary for domestic and foreign risk theories on dangerous goods transportation.Through the analysis of the related concepts of dangerous goods and the status quo of its waterway transport in China,the paper takes typical accident case in Zhoushan as an example combined with risk assessment theory to analyze,and then probes into the features and causes of accidents within jurisdiction to identify the risk factors that affect the safety of water transport.Secondly,Compare various risk assessment methods,select the method of Fuzzy-AHP,take the shipping route of company A as the subject along with its research data and establish assessment index system based on five aspects(people,equipment,dangerous goods,environment and management)so that the weight of each evaluation index is established and calculated by AHP(Analytic Hierarchy Process).Finally,the paper establishes the fuzzy synthetic evaluation model to evaluate the risk of dangerous goods of waterway transport for this company,find the problems and put forward the risk-controlling measures and guide the company to avoid the risk.
