The Evaluation And Analysis System For Ship Navigation Safety Of Ningbo

Great premise for the rapid development of the economic situation now, vigorously develop foreign economic relations and trade, rapid development of the port’s shipping industry. It also heralds I transport development, to promote the development of social productive forces, facilitating the flow of goods and personnel, improve the lives of people and to strengthen national defence has a very important role. Water transportation is not only the world’s trading hub, is one of the resources within the country’s main mode of transport, so that water transportation is also an important component of the development of the national economy. Based on existing data show that China’s port transportation industry, throughput increased dramatically. Coastal port cargo throughput for faster, the average annual growth rate up to9.15%. But these data of indicates that also heralded with, my sea navigation of ship number also with of and increased, its ship of based tonnage increases, equipment of replaced, and all port Zhijian trade route of ship density increasingly large, makes entire route of traffic environment occurred has huge of changes, with of and brings of consequences is water Shang traffic of confusion, its water Shang traffic accident also frequently occurred. In order to prevent and reduce the occurrence of traffic accidents on port water to achieve safe and efficient maritime transportation, among researchers for one marine environment marine traffic system composed of a number of studies. Consists of beilungangqu, zhenhai of Ningbo port, the Ningbo port area, composed of daxie Harbor area, crossing the mountains Harbor, is a river port and estuary and the harbour of Hong Kong in one multi-functional, comprehensive modernization of the deep water port.This chapter reviews the history of the maritime traffic safety evaluation research at home and abroad and the status quo, explains the purpose and significance of the thesis and research methods. Analysis and discussion on chapter Ⅱ port vessel traffic system of the security system, as defined in the system the basic procedure for safety assessment. Simulation on the subject of chapter III of the mathematical model for ship maneuvering motion based on the theoretical modeling analysis of environment under the force. Fourth chapter by fuzzy mathematics theory and establishment of fuzzy comprehensive evaluation model. Fifth chapter of Ningbo port on the first two chapters of theory model of navigation conditions and a safe environment for simulation and quantitative evaluation of the State, the above results, put forward some recommendations to improve the port’s traffic environment. The sixth is on subject research findings and deficiencies, and noted that the issue of new ideas and systems to further improve the concept.
