Maersk Supply Service is launching its offshore vessel-charging venture, Stillstrom. Together with Ørsted, Stillstrom will demonstrate the world’s first full-scale offshore charging station for vessels at an offshore wind farm, scheduled for installation later this year.
The new company will deliver offshore electric charging solutions to vessels at ports, hubs and offshore energy operations. “Stillstrom”, meaning “quiet power” in Danish, is an early-stage technology spin-out, whose full-scale product launch will be the first-to-market in offshore charging, enabling idle vessels to power from clean electricity.
The first full-scale charging buoy will be demonstrated with Ørsted in Q3 2022. The power buoy will supply overnight power to one of Ørsted’s Service Operations Vessels (SOV). Ørsted will be responsible for the grid integration of the charging buoy. Ørsted intends to make publicly available any intellectual property generated during the design of the buoy’s integration into the offshore wind asset, to maximise the potential uptake of this carbon-reducing innovation across the offshore wind sector. The charging buoy itself is large enough to charge an SOV-sized battery- or hybrid-electric vessel. The same solution will be scaled and adapted to supply power to larger vessels, enabling vessels of all sizes to turn off their engines when lying idle. Stillstrom is fully owned by Maersk Supply Service and has received funding support from the Danish Maritime Fund and EUDP.
