Offshore wind energy has grown rapidly in recent years, with 10.9 GW of new capacity added, raising the global total to 75.3 GW, representing a 16% annual growth. This now accounts for 7% of cumulative global offshore installations. Over the next decade, an additional 380 GW is expected to be installed. Türkiye holds a significant offshore wind potential of 75 GW; however, no offshore wind farms are currently in operation. There are ongoing initiatives to mobilize this potential. This study provides a concise overview of offshore wind technologies, including widely used turbine models, transmission systems, and support structures. It also examines current and upcoming offshore wind projects globally. In addition, Türkiye’s offshore wind energy landscape is explored, focusing on historical background, existing capacity, development potential, and policy challenges. A key barrier to offshore wind growth in Türkiye is the instability of government policies and support schemes. Establishing stable and effective regulatory frameworks is crucial for accelerating the country’s offshore wind development and meeting long-term renewable energy targets.
