Study on Foundation Structure for Comprehensive Power Generation of Offshore Renewable Energy

The offshore renewable energy includes offshore wind, wave and tidal current energy. The power generation system of offshore renewable energy uses single form in recent year. It has caused low power efficiency, big power fluctuation and high cost of the foundation structure which will seriously hamper the development of offshore renewable energy. Firstly, a summary about the common form of foundation structure was made. Then basing on the different characteristics of a single energy power generation foundation structure, two different comprehensive power generation foundation types were put forward, and the power generation devices were optimized and reasonably arranged, which are formed a system for comprehensive offshore energy power generation. In addition, the connection, the load and structural features of each comprehensive power generation foundation structure were discussed. The results provide a basis for the design of foundation structure for comprehensive power generation of offshore renewable energy.
