“…Figure 19 shows the soil profile of the Changbin wind farm 40 . During this study, an effective stress ground response analysis was carried out using Cyclic 1D 41 using the unscaled Takatori record (1995 Kobe earthquake) to obtain ground displacements imposed on appropriate p – y curves study the lateral response of the OWT‐foundation system. For the liquefiable and non‐liquefiable layers, hyper‐elastic 34,42 and API 35 p–y curves were considered in this study.…”

Offshore wind power is increasingly becoming a mainstream energy source, and efforts are underway toward their construction in seismic zones. An offshore wind farm consists of generation assets (turbines) and transmission assets (substations and cables). Wind turbines are dynamically sensitive systems due to the proximity of their resonant frequency to that of loads considered in their analyses. Such farms are considered lifeline systems and need to remain operational even after large earthquakes. This study aims to discuss hazard considerations involved in the resilience assessment of offshore wind farms in seismic regions. The complexity of design increases with larger turbines installed in deeper waters, resulting in different types of foundations. In addition, Tsunami inundation is shown to be an important consideration for nearshore turbines.
