Study On The Jetty Navigation Safety

With the continuous development of the international shipping industry，the portthroughput continued to accelerate, the number and tonnage of the ship increased so fast inthe pasting area of jurisdiction that the opportunity between the ships grew.The harbor navigation environment has been a prerequisite for the survival of portdevelopment.Similarly，a excellent navigation environment has became an importantguarantee to improve competitiveness and achieve higher production efficiency importantguarantee.Qinhuangdao Port, the world’s largest coal export port, the coal transportation hub inChina’s, coastline is mostly as jetties to structural arrangement in the open air basin, berthslevel is junior, and quay for mooring is poor. The port berth is limited operational, shorelineutilization efficiency needs to be improved, so that these factors directly or indirectly affecton the Qinhuangdao Port navigation safety.A series of questions such as the navigational safety assessment，regulatory andfeasibility studies or other factors have been further to addressed，with《The regulation ofThe People’s Republic of China on surface and underwater activities navigation safety(2011No.5)》promulgated.Through a combination of the Qinhuangdao Port natural conditions, the shipcharacteristics, and analysis of traffic flow, to protect the safety of navigation and marineclean target by using simulation test technology, in order to get its findings against optimalnavigation recommendations.1、Risk analysis of Navigation safetyThe analysis through human perceptual and historical experience, the accident data,survey records and other objective file, by using for reference of experience, to find all sortsof obvious and potential risks, so as to hold variability of the rule in accidents.2、Analyze the security level navigation as an example of Qinhuangdao PortThe risk factors obtained by brainstorming， putting the natural hydrologicalenvironment into the Qinhuangdao Port, focusing on the analysis of risk factors for eachcorresponding level，to get the analysis of navigation safety.3、Theoretical analysis of the comprehensive use by safety assessment methodAfter clarifying the fundamental risk factors of maritime accident, criteria wereestablished for frequency/severity and risk matrix/risk division in assessments of this kindof risks，which can recognized the major in risk factors.4、Simulation test The study takes an experiment using ship simulator，and simulates the pulling in andout Qinhuangdao port under different conditions to provide effective suggestions andprecautions.5, Navigation safety recommendationsDepending on the results of theoretical analysis and experimental simulation analysis,the most effective way to avoid navigation hazards has found. On the basis of the MarineRegulatory experience of Qinhuangdao Port we put forward a number of aspects of securityconcepts from the research, the focus and so on.6, Summary of this study on inadequate and OutlookWith the continuous development and extensive application of human maritimetechnology, the world shipping systems are moving towards specialization and large-scaleroad continues to advance, though the development will face to obstacles, which includingnavigable environment shared, the establishment of electronic charts, updates of ship-scalerelational database and other information.
