Offshore wind energy is a key component of India's renewable energy roadmap, with significant potential along the coasts of Gujarat and Tamil Nadu. However, seismic hazards pose critical challenges to the structural stability of offshore wind turbines (OWTs). This presentation explores the seismic vulnerability of both fixed-bottom and floating OWTs, focusing on foundation performance under earthquake-induced liquefaction, ground motion, and vertical acceleration effects. Various substructures, including monopiles, jackets, tripods, and floating platforms such as tension leg platforms (TLPs) and spar buoys, are analyzed for their seismic response. Findings suggest that floating wind turbines offer superior resilience due to their inherent flexibility and damping characteristics, whereas fixed-bottom structures face greater risks of tilting and foundation failure. The study highlights the need for robust site-specific seismic assessments and innovative foundation solutions to ensure long-term operational viability in seismically active offshore regions.
