Design of Wind Turbine Supporting Structure in Zhuhai Guishan Offshore Wind Farm
-
Abstract
Zhuhai Guishan Offshore Wind Farm is the first big offshore wind project in the South China Sea. The wind turbine supporting structures have four significant engineering characteristics including offshore structure engineering, towering structure, dynamic equipment, both complicate and soft sea soil as well. Design of wind turbine support structures is one of the most critical and difficult techinical challenges in this project. In this paper, general design contents of supporting structures are introduced. Some key technical topics, like soil parameters and pile-substructure interaction, turbine-substructre-foundaton integrated analysis, frequecy window problem, structure fatigue analysis, corrosion prevention design and grouted connection design are emphasized in this paper.
