| China is a traditional country of chemical raw material importation. With the deeper innovation and the improvement of the international trade in china, the need of chemical raw material has been great enhanced since the 90's of the last century. At the same time, due to the drastic competition between the coast ports of china, how to reduce the cost of operation and explore new cargo for loading and discharging is the most important target, and the great need of chemical raw material give them the chance to build new berth and storage area for chemical operation to make the new improvement in economy. Unfortunately due to the poor management and the low technology, the speed of the development is lower. As one of the earliest liquid chemical operation area in China, Zhenhai District of Ningbo Port is the largest transshipment base of China for imported liquid chemicals at present and the liquid chemical throughput has been ranking the first place among China's coastal ports for seven years. But the recent development shows that with the great improvement of throughout and the intervention of the oil operation the loading and discharging system of Zhenhai District has already not fitted the need of toady and future, so building new berth and storage area and the innovation of old handling system are the most emergent things for the port to do. The article is just base on the above background to do some researches about the liquid chemical loading and discharging system of Zhenhai District, try to use some system analyze tools , combining the situation today and future will be, to find out a suit of layout project of the liquid chemical handling system which fit the need of the future.The whole paper includes introduction and five chapters. The main content of introduction give you a simple impression of the District, meanwhile the author point out the existing problems and the way how to solve them. Chapter one introduces the present status of the District in detail, including the berth, storage area, equipments, handling system, scale, trend and so on. Chapter two following the above introductionanalyze the present status of the District. With the introduction of the liquid chemical loading and discharging system and how operating in Zhenhai District, combining the recent statistics date of the port, the chapter analyzes the berth throughout, use-rate of berth, need of the storage area and point out the main problem now existing. Chapter three combining the new project of the District analyzes the handling system layout entirely, meanwhile it builds four series of liquid chemical transfer-lines projects which fit the need of the future. The four projects have been demonstrated with the analyze of the three actors which make up the project. Chapter four is the process of the best choice of the four projects. The author use fuzzy multiple evaluation theory and AHP theory to solve the problem, meanwhile establish the current calculate formula of the subjection function, ameliorate the deficiency of fuzzy multiple evaluation theory, enhance the veracity of the result of evaluation. The best choice is worked out with the calculation which based on the above theory. The last chapter is the summarize of the whole paper and give some advice to the project.The research of port handling system is now generally focus on general cargo and bulk cargo. The scarce of the chemical handling ports, small scale, lower management and technology, complex special chemical knowledge make the researches and references in this facet scarcely, as the largest scale of chemical handling area in China, the research of Zhenhai chemical handling District is advanced and representative. Another characteristic of the paper is that the research is not based on complex special chemical knowledge but management to analyze the commonness of the system, it is a breakthrough of the tradition which means the design of chemical handling system must be based on the special chemical knowledge . On the research metho... |
