Aker Options and the Marine Vitality Check Centre (METCentre) in Norway have signed a front-end engineering and design (FEED) contract for a pilot undertaking which can see Aker Options testing its new energy transmission expertise on the METCentre’s offshore take a look at space that homes demonstration floating wind generators.
In keeping with Aker Options, the brand new energy system expertise, referred to as the Subsea Collector, connects a number of wind generators in a star configuration as a substitute of the standard daisy chain sample and has the potential to scale back the prices of offshore transmission infrastructure by as much as 10 per cent.
The principle elements of the Subsea Collector are a 66kV moist mate connection system, subsea switchgear with supervisory management and knowledge acquisition, and a static export cable.
“The primary-of-its-kind system has been developed following the confirmed success of comparable applied sciences in massive set up tasks and Aker Options’ expertise in subsea energy options for subsea fuel compression and extra not too long ago for floating offshore wind like Equinor’s Hywind Tampen,” Aker Options mentioned in a press launch on 3 January.
Aker Options says that the system’s design permits for extra flexibility in offshore wind farm structure and development, in addition to for diminished cable size per turbine and wind farm, and fewer vessel time and set up prices.
Preliminary findings help whole price financial savings on a 1 GW floating wind farm of as much as 10 per cent, in response to the corporate.
For the pilot undertaking in Norway, Benestad will provide the moist mate connection system and ABB will ship subsea switchgear. The Subsea Collector on the METCentre will likely be put in by Windstaller Alliance, an alliance between Aker Options, DeepOcean and Solstad Offshore, with Aker Options additionally offering the static export cable to shore.
“The Subsea Collector is a superb instance of true trade collaboration. Combining Aker Options’ huge subsea expertise with our associate’s confirmed management and connection techniques, we purpose to resolve challenges at the moment going through the offshore wind sector. We hope this undertaking will end in a discipline confirmed system that may profit the trade for a few years to return,” mentioned Jo Kjetil Krabbe, government vice chairman of Energy Options at Aker Options.
METCentre’s offshore wind take a look at space, positioned 10 kilometres off the southwestern coast of Karmøy in Norway, at the moment has two floating wind generators and can increase to seven floating wind generators from 2026.
For its new cable infrastructure, the METCentre evaluated a number of configurations and determined to maneuver ahead with a pilot set up of Aker Options’ Subsea Collector to allow the enlargement of the take a look at website, in response to the press launch from Aker Options.
“This pioneering undertaking will contribute to shaping the infrastructure in future massive scale floating wind parks. The expertise is underneath improvement, and the undertaking demonstrates how Norwegian subsea experience from the oil and fuel trade drives innovation ahead inside floating offshore wind on a world scale,” mentioned Arvid Nesse, CEO of METCentre and Norwegian Offshore Wind.
