Paris-listed contractor Technip Energies has won the front-end engineering and design contract for Equinor’s Firefly offshore floating wind project in South Korea.

Technip Energies’ workscope involves the engineering of the floating wind turbine substructures for the proposed 800-megawatt offshore wind farm.

The design of the substructures will include the contractor’s in-house floater technology INO15.

With a capacity of 15 megawatts, INO15 technology is a three columns semi-submersible floater, which Technip Energies said is well suited for fabrication in large series.

The substructure design is in alignment with Equinor’s wind semi design principles.

The Firefly wind farm is planned for an area of two times 75 square kilometres, some 70 kilometres off the coast of the city of Ulsan.

The facility, which will deliver power into the national grid, is planned to be in operation in 2027.

“We are glad to have been awarded this FEED by our long-lasting client Equinor and that the INO15 floater technology has been selected for the development of the offshore wind farm,” said Technip Energies vice president for offshore floating wind Willy Gauttier.

“It perfectly illustrates that engineering and technology will be key to accelerate the energy transition. Through the Firefly project, we are committed to support Equinor in its objective to reach an installed net renewables capacity of 12 to 16 gigawatts by 2030.”

The value of Technip Energies' FEED contract was not disclosed.
