This is intended for use in floating wind farms and for off-grid applications, including temporary electrification of oil and gas installations in harsh environments.
In January DNV awarded the foundation Approval in Principle from DNV; the main scantling class approval is based on Siemens Gamesa’s SG 11.0-200 DD offshore wind turbine, combined with the integrated foundation.
Deepsea Semi is designed for low-cost, industrial mass production and has been dimensioned for wind turbine generators up to 15 MW, including the SG 14.0-236 DD.
Odfjell Oceanwind now aims to secure DNV class approval of the foundation for these larger turbines, which should soon be commercially available for floating application.
The design basis is said to cover all areas for floating wind farms currently in planning in the North Sea, Norwegian Sea and Barents Sea, and prospective areas related to the UK INTOG process. It covers water depths in the range 60 m to 1,300 m.
Odfjell Oceanwind CEO Per Lund said, “We continue building on the long-term relationship with DNV, which we plan to extend also through full classification and certification of floating offshore wind units for wind park application as well as our own fleet of mobile offshore wind units for off-grid application.
“We now have a product readily available and very well suited for near-term oil and gas electrification initiatives, innovation parks in northwest Europe as well as wind park projects like Utsira Nord, Celtic Sea and Scotwind, including locations West of Shetland.”
Odfjell Oceanwind envisages the wind units typically starting operations around two years from orders being placed.
Its mobile offshore wind units for electrifying offshore oil and gas installations would complement power from shore.
