Wind propulsion systems provider Norsepower installed its Rotor Sail Solution to a Scandlines hybrid ferry in a matter of hours during a scheduled overnight stop.
The rotor sail is estimated to reduce emissions by 5% without compromising speed or voyage times.
The unit was fitted to M/V Copenhagen in the German port of Rostock. It is 30m tall and 5m in diameter, and can be installed in new vessels or retrofitted.
It is a modernized version of the Flettner rotor, a spinning cylinder using the Magnus effect to harness wind power to move the ship.
Soren Poulsgaard Jensen, CEO of Scandlines, said, “On our modern hybrid ferry, this solution will sit alongside hydrodynamic hull optimization, and a hybrid electric propulsion system with a battery powered energy storage system, improving not only our efficiency but also profitability.”
M/V Copenhagen operates between Rostock, Germany, and Gedser, Denmark.
