21st century mankind will have new opportunities to develop and utilize the ocean. There are more than 18, 000 km of mainland coastline. According to China has approved the "United Nations Convention on the Law of the Sea", China has nearly 3, 000, 000 square kilometers of sea area may have jurisdiction, which is equivalent to one-third of China's land area. This will be the land of blue ocean minerals, chemicals, energy, biotechnology, space development and utilization of resources of the battlefield. In recent decades, the reform and opening to the coastal areas of economic development brought about by the rapid development of port construction from the coastal zone development, from the beach promenade to the use of marine oil and gas development, the use of all buoys (including submarine-S), and other measurement devices to monitor environmental data As a scientific basis for engineering design. Domestic marine industry import a considerable number of small streams, such as buoys and measurement equipment, has invested dozens of coastal engineering point of the development of the service. Therefore, great efforts to develop our own marine resources for development and economic construction of the ocean buoys into the ocean system is the top priority of the century.Buoy is the foundation of a buoy system. In addition to the physical design of the buoy to buoy deployment of the sea limits based on environmental conditions, to meet China's "sea-going stability of the norms of" infinite area requirements, Also called buoy has a good follow the wave of performance, Since the shake-buoy cycle to avoid the common area of deployment buoy wave cycle in order to avoid potential resonance. At the same time, drag and drop, towing, . deployment, recovery, to facilitate maintenance. Therefore it is necessary to buoy the power-performance analysis. After the body as a buoy for the design, modifications, Anchorage and analysis of the dynamic properties of reference.In this paper, the use of wave theory of the disc-shaped 10-meter buoy in a free state and bound by the state roll, heave movement in response to the analysis derived in response to the equation. In the dynamic simulation for checking the strength of the mast, will buoy the equation as a response to the load conditions. From the static and dynamic aspects of the mast was checking intensity. Mooring buoys on the mechanics of the calculation of chain-calculated amount of drift and power cable, and so made a more detailed description.From the mast of the characteristics of stress on the point of view of the mast structure to improve, and static and dynamic aspects of the strength of the mast were checking to verify the structure is reasonable. After the platform for the marine Pole has a certain structure to provide a high degree of design and technical support.
