Wind Energy – FEED Contract
Aker Solutions has signed a front-end engineering and design (FEED) contract with the Marine Energy Test Centre (METCentre) in Norway to pilot new subsea power system technology which has the potential to significantly reduce the costs and complexity of offshore wind farms.
The project will see Aker Solutions provide new power transmission technology, Subsea Collector, for the METCentre’s offshore wind test area which today consists of two floating offshore wind turbines located 10 kilometers off the southwestern coast of Karmøy, Norway. The test area will expand to seven floating offshore wind turbines from 2026.
Subsea Collector provides an alternative solution to connect multiple wind turbines electrically in a star configuration instead of the traditional daisy chain pattern, allowing for more flexibility in offshore wind farm architecture and construction.
The design also allows for reduced cable length per turbine and park, as well as less vessel time and installation costs. Initial findings support total cost savings on a 1GW floating wind farm of up to 10 percent.
The main component parts of the Subsea Collector comprise a 66kV wet mate connection system provided by Benestad and subsea switchgear with supervisory control and data acquisition by subsea power and automation alliance partner, ABB.
Installation will be carried out by Windstaller Alliance, an alliance between Aker Solutions, DeepOcean and Solstad Offshore. Aker Solutions will also provide the static export cable to shore.
The METCentre evaluated several alternative configurations for its new cable infrastructure and concluded by moving forward with a pilot installation of Aker Solutions’ Subsea Collector to enable the expansion of the test site.
