Study On The Improvement Of Fairways And Anchorages Of Dalian Port

With the development of navigation, ships become bigger, faster and more specialized than ever. However the traffic condition in the Dalian port deteriorates due to the high traffic density. The number of traffic accidents in the port increases every year. Ship collision and the perils from the breed aquatics in the fairway and anchorage severely endanger the safety of the marine traffic in the port. Attention should be paid to the increase of danger in navigation.According to the plan of port development and also to satisfy the need of marine safety administration, investigation on the traffic flow is carried out. This investigation is aimed to improve the traffic condition by reforming the anchorage and fairway system.Marine traffic survey is the basis of traffic evaluation and reform. The distribution of track, the distribution of density and the distribution of speed are plotted out by investigation and reference to historical data. A traffic flow model is built. In the light of the information, this paper points out the defects of the existing anchorage and fairway system.A optimized scheme is put forward by analyzing the traffic condition in the port, the particular problem of the traffic flow of the existing system and the statistic data from investigation. The design of some famous ports is referred and opinions of experts are adopted while designing the system. The improved system of anchorage and fairway is simulated on the navigation simulator. Fuzzy mathematics is applied to exhibit the priorities of the new system over the existing one.If this plan is adopted, the traffic condition will be improved dramatically and traffic accidents will be greatly reduced. It can also speed up the efficiency of the port and accelerate the economic development of the whole city.
