Fuzzy Comprehensive Evaluation Of Safe Passage For The Ships Calling At Port Of Qingdao

The world economic integration and the development of shipping industry, make intelligent ship and the trend of large-scale increasingly significant. Qingdao waters since the implementation of ships routing system in 2007, in and out of the ship’s side of the road, to some extent avoid the occurrence of the complicated situation, purify the navigation environment, improve the traffic efficiency. But with the rapid development of Qingdao port, in and out of the quantity and the type of increasing, so the ships in the channel density increasing, and the existence of the line intersection, encounter probability increase greatly, increasing traffic safety risk.Maritime traffic accidents are very large in the vicinity of the port, which will also cause very bad impact on the waters. However, with the development of economy and shipping, the number of ships and the density of vessels are increasing, so that the safety of navigation in the dense waters of ships is becoming more and more severe. With Qingdao port waters of the natural conditions and the present navigation situation, enumerate many influencing factors of the water traffic safety, and risk degree of qualitative and quantitative analysis and evaluation of the various elements, thus the selection of the key elements, further established the waters navigation safety evaluation index system, combined with related knowledge to establish the mathematical model, fuzzy comprehensive evaluation of Qingdao port navigation safety, come to Qingdao port waters navigation safety between low risk and general risk degree between, and according to the key elements of the proposed some specific measures to avoid the existence of navigation risk.Through this study, we can make the work of the Qingdao port area of the driving personnel to give a higher degree of attention, to ensure that the waters of the navigation order and efficiency, as far as possible to reduce the possibility of the occurrence of marine accidents, to ensure the safety of navigation, and the operation and management of the waters have a certain reference.
