초록
The wind power industry continues to grow, driven by environmental concerns such as achieving carbon neutrality, which has recently gained prominence. Creating wind farms poses several challenges due to limited land availability and insufficient wind resources. Consequently, offshore wind projects are garnering attention, particularly in domestic conditions. Notably, the Southwest Sea of Korea exhibits the highest offshore wind potential and has validated this potential through demonstrations. The primary geolog-ical characteristic of the Southwest Sea is a weak clay layer. To ensure the stable operation of generators, enhancing the precision of the substructure becomes imperative. This study presents an engineering procedure for developing a jacket-shaped wind turbine sub-structure, which was analyzed to assess the impact of soil properties on structural strength. In a previous study, wind turbine capacity targeted 5 MW. However, in alignment with the technological trend in the Southwest Sea offshore wind turbine market, this analysis model focuses on the 12 MW class. The structural response under varying soil conditions was verified using data from the North Sea, Mexico Bay, and Southwest Sea. The findings of this study not only contribute to designing structurally sound wind turbine substruc-tures but also serve as essential reference data for engineers in related fields, providing insights into structural safety design and ana-lytical verification processes.
Abstract
The wind power industry continues to grow, driven by environmental concerns such as achieving carbon neutrality, which has recently gained prominence. Creating wind farms poses several challenges due to limited land availability and insufficient wind resources.

Notably, the Southwest Sea of Korea exhibits the highest offshore wind potential and has validated this potential through demonstrations. The primary geolog-ical characteristic of the Southwest Sea is a weak clay layer. To ensure the stable operation of generators, enhancing the precision of the substructure becomes imperative. This study presents an engineering procedure for developing a jacket-shaped wind turbine sub-structure, which was analyzed to assess the impact of soil properties on structural strength. In a previous study, wind turbine capacity targeted 5 MW.
