Abstract

In this study, global in-place analysis of WTIV (Wind Turbine Installation Vessel) leg for Korean west-south offshore wind zone is performed through finite element analysis. Firstly, environmental conditions and seabed characteristics of Korea west-south offshore wind zone is collected and investigated through both direct measurements and literature surveys. Based on these data, design specifications are established and the overall basic design is performed. Dynamic characteristics of the WTIV for Korean west-south offshore wind zone are considered in the global in-place analysis of leg and the stability against overturning moment is also analyzed. The structural integrity of the WTIV leg is verified through the code checks and the adequate safety margin is observed. The results of this study can be expected as practical and useful data for the design of the WTIV for Korean west-south offshore wind zone.
