Abstract: Offshore wind energy offers a huge potential for the expansion of renewable energies in China. High demands have to be made concerning foundation design and construction methods to find an economically and technically optimal solution. A promising foundation concept which can be more and more widely used in large capacity offshore wind turbines is the super monopile. It is important to quickly find out the availability of monopile, which is determined by factors such as the natural frequency of the turbine-foundation system, the horizontal displacement and the drivability of large-diameter steel piles.Based on the design practice and experience of some offshore wind farms in Guangdong Province, the flow chart and key points were summarized, which can be applied to the design of pile foundation offshore wind turbines.
