An offshore vessel-charging venture is being launched by Maersk Supply Service to support the decarbonization of the maritime industry by eliminating idle emissions. Together with wind energy developer Ørsted, new spinoff Stillstrom will demonstrate the world’s first full-scale offshore charging station for vessels at an offshore wind farm, scheduled for installation later in 2022.

Offshore charging for idle vessels allows operators to replace fossil fuels with electricity while being safely moored to the charging buoy, which will be sized to charge a battery onboard a service operation vessel or a hybrid electric vessel. The technology can also be scaled up to supply power to larger vessels, enabling ships of all sizes to shut down their engines when idling.

When integrated into an Ørsted wind farm in the North Sea, the charging buoy will use clean wind energy to provide overnight power to one of Ørsted's service operating vessels.
