IOG Wind Secures Long-Term Balance of Plant Contract with the Hai Long Offshore Wind Project

16 October 2025

IOG Wind (formerly known as CWind Taiwan) announced that it has secured a multi-year operations and maintenance (O&M) contract for the Balance of Plant (BoP) of the Hai Long Offshore Wind Project. This is IOG Wind’s second long-term O&M contract since its establishment in 2018 and the first since becoming a wholly owned subsidiary of International Ocean Group in 2023, demonstrating the company’s strengthened local expertise and the trust it has earned from clients

The scope will cover inspections of newly installed offshore substations, as well as undertaking inspection, maintenance, and troubleshooting of transition pieces (TP), subsea foundations, and other structural components. Further works, including subsea cable inspections and onshore substation operations, are planned to commence soon.

Located 45–70 kilometers off the coast of Changhua County at depths of 35–60 meters, the Hai Long Project consists of Hai Long 2 and Hai Long 3, with a total of 73 turbines. The Hai Long Project has its commercial operation targeted by the end of 2026, delivering more than 1 GW of installed capacity.

Tim Kittelhake, CEO and Project Director of the Hai Long Project, said: “As the largest offshore wind project in APAC, we have signed over 100 contracts with Taiwanese suppliers during the construction phase, with a total value exceeding USD 4 billion. Now, as we move toward grid connection and prepare to enter the O&M phase, we are confident that IOG Wind’s strong technical expertise and mature management capabilities will ensure the stable, safe, and efficient operation of the Hai Long wind farm after commercial operation, while also supporting the long-term development of Taiwan’s offshore wind supply chain.”

Vincent Tsai, Chairman of IOG, said: “We are truly honored to have secured this significant contract with the Hai Long Project. Since its establishment, IOG Wind has consistently expanded its service scope and strengthened local execution capabilities, supported by a professional team of sales, engineers, and resilient project management expertise. Following IOG’s full acquisition of CWind Taiwan (IOG Wind was formerly known as CWind Taiwan), we are proud that our professional strengths remain consistently acknowledged by clients. Through innovative and optimized solutions, and by further advancing Taiwan’s local supply chain, IOG Wind will support Hai Long in maximizing performance and revenue throughout its lifecycle, while contributing to Taiwan’s sustainable energy future.”
