—In this study, wave force tests were carried out for the four types of offshore support structures and wave forces to the support structure shapes were investigated. As the results of this study, it was found that, as the wave period increased at the normal state, wave force decreased for the most cases. Extreme wave force influenced by impact wave force. Impact wave force of this study significantly effect on Monopile and minutely on Hybrid type. So as to, Hybrid type indicated even lower wave force at the extreme state than the Monopile, although Hybrid type indicated higher wave force at the normal state. In respects of the structural design, since critical loading is extreme wave force, it should be contributed to improve structural safety of offshore support structure. However, since the impact wave force was dependent on the support structure shape, wave height, and wave period, more research is needed to access the impact wave force for other shapes and wave conditions.
