Abstract
In this study, a global in-place analysis of the WTIV (Wind Turbine Installation Vessel) leg for the Korean west-south offshore wind zone is performed through Finite Element Analysis (FEA). The environmental conditions and seabed characteristics of the Korean west-south offshore wind zone are first collected and investigated through direct measurements and literature surveys. Based on these data, the design specifications are established and the overall basic design is performed. The dynamic characteristics of the WTIV for the Korean west-south offshore wind zone are considered in the global in-place analysis of the leg, and the stability against the Overturning Moment (OTM) is analyzed. The structural integrity of the WTIV leg is verified through code checks, and the adequate safety margin is observed. The results of this study can be expected to be practical and useful data for the design of the WTIV for the Korean west-south offshore wind zone.
