Technip Energies, Subsea 7 and Samkang M&T Perform FEED
Corio Generation and TotalEnergies selected Technip Energies, in alliance with Subsea 7 and Samkang M&T, to perform the Front End Engineering Design (FEED) for their Ulsan Gray Whale 3 Offshore Windfarm Project. The design is located off the east coast of Korea.

The FEED contract covers the engineering of the float, mooring, and array cable (IAC) in collaboration with the wind turbine provider.
The floating foundation design will include Technip Energies’ internal floating point technology, INO15™. The INO15™ technology has a capacity of 15 MW and is a three-row semi-familiar floating point, ideal for large series production.
Gray Whale 3 aims to develop a 504 MW floating offshore wind farm, approximately 60 to 70 km from Onsan Port in Ursan, one of three offshore wind projects with a total installed capacity of 1.5 gigawatts. Corio Generation and Totalerenergies have contributed to promoting Ursan’s coast.
Laure Mandrou of Technip Energies commented: “We are delighted to have been selected along with Subsea 7 and Samkang to execute this important offshore wind project feed-in. In leveraging the complementary nature of our in-house floating technology, INO15TM, and strong industrial players, we are pleased to contribute to building the future of floating offshore wind in Korea, thereby contributing to the global energy transition.”
Philippe Gleize, Vice President of Floating Wind, said at Subsea 7: “The Gray Whale 3 offshore wind project is an exciting opportunity for Subsea 7 to further advance our participation in the Korean floating wind market. We are delighted to have been selected as a consortium partner and look forward to working with our client and all parties to maximize the knowledge, capabilities, and expertise we bring together to deliver this feeder project.”
Song Moo-Suk, Chairman of Samkang M&T, said, “Floating offshore wind projects are a ground-breaking alternative to address the limitations of fixed projects and require state-of-the-art technology and construction capabilities. Building on the expertise accumulated from successful offshore wind substructure projects such as those in Taiwan and the UK, we will secure a firm position as a global leader.
