Abstract: Wind turbines on jackets are being increasingly installed offshore. This paper attempts to investigate the effect of soil-structure interaction (SSI) on a jacket-offshore wind turbine (OWT) in a water depth of 70 m using JONSWAP spectrum. Stochastic responses of the OWT under varying soil profiles and met-ocean conditions are studied, by coupling the aerodynamic and hydrodynamic forces. From stochastic time domain response analyses, the SSI is observed to have significant influence in soft clay and layered soils at and above rated wind speeds whereas the dense sand have negligible influence.
