Qingdao Dongjiakou Port300,000-ton Waterway Traffic Risk Assessment

Since the reform and opening up, China's economic has been rapidly developing, import and export trade is obtained the unprecedented development, and the shipping industry has been rapid development, port number, port's throughput increase sharply. The number and tonnage of ships is increasing, and the speed is faster and faster, but the width, depth and the total amount of allowing the ship through is limited. These factors make the traffic of the port and its nearby waters more and more crowded, ship density is larger, the navigation environment is increasingly complex. Corresponds to the probability of ship traffic accidents is also increasing,and the level of navigation risk assessment is a major sign of the level of a national water safety of navigation, and an important symbol of national shipping powers. It is in such a background, more and more experts and scholars studied the navigation risk. On the basics of conducting a comprehensive study and evaluation to the ship navigation environment risk, take effective measures to reduce the risks and improvet the traffic environment.The article combine the actual situation of Dongjiakou Port Entrance Channel, make full use of the mathematical theory and use the qualitative and quantitative combination of evaluation methods to determine the channel risk status, and through the ship maneuvering simulator to validate the test results of mathematical theory.Firstly, analysis of Dongjiakou Port information, statistics in recent years Dongjiakou Port kinds of data;Secondly, through the Shandong maritime bureau, Qingdao maritime bureau and Dongjiakou Port field research, then listen to the experts, the ship pilot, port management advice, determine the main factors and the degree of risk of the safe navigation of ships. on this basis, to determine waters risk assessment system of Dongjiakou Port Entrance Channel, and the applicate the analytic hierarchy process to determine the index weight; Then applicate set pair analysis to evaluat Dongjiakou port channel navigation environment risk, and analyze the evaluation results,and using the ship maneuvering simulator to verificate the set pair analtysis results. This article carry on the risk assessment of the Dongjiakou channel, you can very well understand and master the Dongjiakou harbor navigation environment risk degree and each factor risk. For the authorities to provide scientific and rational decision-making reference and improve the Dongjiakou port navigation environment safety level as well as the navigation control and management and other aspects. With the maritime practice need, so it has good practical value.
