Stillstrom trial with Ørsted

Maersk Supply Service and Ørsted have joined forces to test a pilot buoy in 2023. The trial will take place at one of Ørsted’s  wind farms in the North Sea, with the Stillstrom prototype buoy supplying power to the Service Operation Vessels (SOVs) and Crew Transfer Vessels (CTVs) operating at the farm.
