“…The numerical analysis technique that showed good agreement with the test results was further analyzed. Do et al (2023) conducted a collision-damage analysis for a semi-submersible floater that applied a taut mooring system and developed a residual-strength estimation formula based on the damage incurred. The floater of a floating wind turbine can be flooded below the sea level when damaged by ship collision.…”

However, complex risk factors arise from the sea. Among them, ultimate limit states (ULS), such as typhoons, are considered in the design phase of offshore wind turbines, whereas the accidental limit state (ALS), which may occur during the operating period, is not sufficiently considered. The ALS must be considered in the design phase because collision accidents with ships may occur during the operation of marine structures. Although the occurrence frequency is low, the risk of such accidents is high.In 2020, the fixed offshore wind turbine structure of the Borkum Rifgrund wind farm in Germany collided with a 26-m-long high-speed vessel (Renews, 2020). In 2021, a jack-up vessel mobilized for the installation of a wind farm in the waters of Huizhou City, China collided with a substructure (BBN, 2021). In 2022, the monopile substructure of a fixed offshore wind farm in the Netherlands North Sea collided with the bulk carrier "Julietta D," and the installed substructure was dismantled (Durakovik, 2022). In the Netherlands' Hallandse Kust Zuid offshore wind farm, a cargo ship collided with a
