The Study Of Navigation Safety Evaluationin And Countermeasure Of Nvdao Port

with the great development of the port, there are a lot of engineering under construction, which make the navigation environment more complicated and cause a lot of issues of navigation safety. The number and categories of ships arriving at and leaving port increase, and the tonnage of ships become larger, which cause the encounter rate of ships raising and make the avoidance of ships harder. There is much more possibility occurring a marine casualty and the consequence is more catastrophic.According to the characteristics of waters in Nvdao port,the paper researches on risk assessment of navigation safety in Nvdao port combining with the reality of navigation environment in the water.Considering the influence of ship navigation safety and port waters all the risk factors of uncertainty and complexity,a navigation risk assessment method is simply not comprehensive and reasonable interpretation port waters navigation safety risk factors on the influence of ship navigation safety.Therefore,this paper uses the analytic hierarchy process (AHP) and fuzzy comprehensive evaluation method,comprehensively reflect the Nvdao port waters of navigation safety risk factors influence degree and the overall situation,to Nvdao port navigation safety assessment.According to the analysis results,together with the present situation of Nvdao port area,put forward the reasonable safety of maritime navigation safety precautions.
