Daewoo Engineering has obtained international certification for its 22MW floating offshore wind model, the largest of its kind in South Korea.
On September 21, Daewoo Engineering announced that its 22MW floating offshore wind model, developed in collaboration with the floating offshore wind research team, received Approval in Principle (AiP) from both Norway's DNV and France's BV.
This certification recognizes Daewoo Engineering's design capabilities and structural stability for the 22MW floating offshore wind model. The company explained that as competition intensifies globally for the development of large floating structures exceeding 20MW, this achievement enhances its technological competitiveness in the domestic offshore wind substructure sector.
Floating offshore wind involves installing wind turbines on structures that float on the sea, making it possible to deploy them in deep waters. This method is gaining attention as a next-generation eco-friendly energy source, particularly suitable for the East Sea region, which has strong winds and deep waters, marking it as a key growth area for South Korea's offshore wind industry.
Since being selected as a national project in April 2023 for the development of innovative LCOE-reducing design technology for 20MW+ large floating offshore wind substructures, Daewoo Engineering and the research team have been advancing their technology. They obtained a related patent in February 2025 and completed tank tests using a 1:49 scale model at the Korea Research Institute of Ships and Ocean Engineering (KRISO) in September of the same year.
The model, developed jointly by Daewoo Engineering and the floating offshore wind research team with support from the Korea Energy Technology Evaluation Institute, includes participation from various domestic industry, academia, and research institutions such as Bandi Consultant, POSCO, Marine Techin, Inha University, Korea Institute of Civil Engineering and Building Technology, Korea Register of Shipping, Korea Dongseo Power, and POSCO E&C.
The 22MW model, validated by DNV and BV, is designed to maintain structural stability in environments with depths of up to 150 meters in the East Sea. It also features a reduction of approximately 20% in Levelized Cost of Energy (LCOE) compared to existing models.
Based on this international certification, Daewoo Engineering plans to leverage its technology for future domestic and international floating offshore wind project contracts and commercialization.
A Daewoo Engineering official stated, "Following the promotion of the fixed offshore wind project at Guyeopdo (250MW), our 22MW floating offshore wind model has been recognized for its technological capabilities by the world's leading classification societies, DNV and BV. We will continue to strengthen our core technological competitiveness in the renewable energy sector to lead the global offshore wind market and secure future growth engines."
