Analyzing The Environmental Safety Of Navigation In Port Taking Dalian Port As An Example

In recent years, the shipping industry has rapidly thrived with the rapid development of China's trade, and the cargo-handling capacity has dramatic increased in port at the same period. According to statistics of Ministry, China's cargo-handling capacity increases rapidly through 10 million tons at the early years of New China to 7.657 billion tons at present. The number of ports that the cargo-handling capacity excelled billion tons becomes twenty. The growth rate has become the first class in the world.Subsequently, the type of ship leads to large-scale, high-speed and diversified. Own to the congestion, increased harbor facilities, etc, which led to navigation environment of the port has undergone tremendous changes. Navigation environment becomes more and more complex which will bring more and more difficulty to the ship offices who handle the ship in the harbor area. At present, the level of navigational safety assessment weighs out the level of a country's shipping industry, but also a Important indicator transition. In order to reduce accidents, we can improve the navigation environment by using the environmentally safe assessment and systematic analysis.In this paper, we research the environment of ship's safe navigation in Dalian port by using safety assessment method and its application. First, using of relevant theoretical results, applications, safety analysis method of navigating the waters to analysis the port environment, security of the system; Secondly, Through the investigation by experts, we provided an assessment model for port security by using the fuzzy comprehensive evaluation of relevant theory. Finally, based on the collection and investigation of the application evaluation model, we evaluated and analysis the navigation environmental safety in Dalian Port Waters.Through the safety assessment, we can understand and master the Dalian port waters navigation safety and environmental risk factors easier. Thus, it can provide a scientific basis for decision making and reference for the management of MSA and department of port. In a word, the research has some practical valuable.
