China's offshore wind power sector is rapidly progressing with large-scale and efficient projects. To support large-capacity wind turbines (LWTs), there is an increasing need for advanced tower structures that offer superior structural performance and economic efficiency. One such innovative solution is the hybrid fiber-reinforced composite materials (FRP)-concrete-steel prestressed double-skin wind turbine towers, which can be termed PDSWTs hereafter. PDSWTs, proposed by scholars of The Hong Kong Polytechnic University, incorporate circular FRP-concrete-steel double-shin tubular members (hybrid DSTM) as the basic component. PDSWTs boast excellent durability, high load-bearing capacity, and exceptional stability, resulting in the potential to reduce production and maintenance costs throughout the service life. This paper presents a study on the design procedures of PDSWTs using a tower that supports 12MW offshore LWT as an example, based on the provisions in the current design standards and codes. The results demonstrate that: the tower successfully meets the frequency requirements of LWT that can avoid encountering resonance; the tower possesses high ultimate resistance under compression-bending, shear and torsional loadings of ultimate limit states; the strain, stress, crack width and tower deformation under serviceability limit states meet the requirements of current design standards; furthermore, a simplified method is proposed to check the fatigue resistance of steel and concrete in the tower sections. This paper is expected to provide references for the design and application of PDSWTs.
