This study aims to investigate the collision between ships and concrete columns of Floating Offshore Wind Turbines (FOWTs). Research on collisions between FOWTs and ships is increasing due to the growing demand for alternative energy sources; however, there is a lack of research specifically focused on concrete floaters compared to fixed or steel floaters. In this study, the collision between the ship and the concrete column of FOWT was conducted using the nonlinear finite element analysis program LS-DYNA. Specifically, the focus was on Pre-Stressed Concrete (PSC) rather than Reinforced Concrete (RC) without prestress. Modelling techniques for applying prestress to hollow cylindrical concrete structures are discussed. The damage of RC and PSC after a collision is compared. The PSC model showed significantly less damage and improved stress states than RC. Furthermore, parametric studies were conducted on collision velocity, strain rate effects, and concrete material models. The strain rate effect was considered only for concrete. The application of the strain rate effect on concrete had a significant influence on the structural damage. The force-displacement curves obtained from this research can be used as input data for the global analysis of collisions involving FOWTs.
