Shanghai Maritime Safety Administration Building Swath Applied To The Maritime Administration Of The Technical And Economic Feasibility Study

With the continuous, rapid and sound development of our national economy, the import and export trade increase steadily, the inshore opening-up extend more, communications and transportation is in great demand, the shipping industry comes into the unprecedented prosperous situation, the waterborne transportation flow increased, shipping industry developed towards large-scale and high-speed. During the State's Tenth Five-Year Plan period, the country proposes the strategic policy of building shanghai the international shipping center clearly, especially in recent years, Shanghai Harbor marches towards the international shipping center are further strengthened, the construction pace of moving outside the harbor and combination of the harbor are further accelerated, besides continuing putting into the construction of the fifth stage of container terminal of Waigaoqiao project, the construction of the Yangshan deep water port is the key projects of the country and Shanghai . The construction of the international shipping center, besides offering advanced hardware facilities, the soft environment of the high-quality, high-efficient, security is the condition that an international shipping center must possess too, and the good water traffic safety order is an extremely important condition of soft environment in an international shipping center construction, in order to adapt to the construction of the international shipping center of Shanghai, port unit like customs , frontier unit put into a large amount of manpower and materials and the soft environmental constructions related to international shipping center in succession, meanwhile, to ensure the work to put forward the new request of Shanghai Maritime Affairs Bureau who is responsible for Shanghai harbor water traffic safety supervision management and boat policy management, in order to adapt to the construction of fast-developing international shipping center of Shanghai, it is immanency to research and construct and implement of boat policy to develop the high-capacity and high-technology patrol ships.The research of this thesis is under the circumstances that the international shipping center of Shanghai builds Yangshan deep water port project, first of all, through its SWOT analytical method analyze Shanghai maritime affairs situation, maritime affairs office existing boat policy, Yangshan deep water porthydrometeorological situation, analyze the present main ship type, to explain the background of the choice the ship the small waterline, to put forward the necessity of building small water-plane area twin hull (SWATH) maritime affairs patrol ships. Then, it introduces the principle, characteristic of the small waterline, and has analyzed the domestic and international state of development of the SWATH ship, and conclude that it is feasible to build SWATH maritime affairs patrol ship technical, through the research and analyze of design at home and abroad,; Then it analyzed the application of the SWATH ship in maritime affairs manage both at home and abroad, put forward the preliminary scheme, and carry on research to the economic performance of technology of the scheme, through putting forward the preliminary model of plan of design to main yardstick and selecting type of host computer finally after relatively optimize, and confirm design specifications .
