Triple Hybrid for the Baltic Sea

Scandlines is installing a rotor sail on board the hybrid ferry Copenhagen in order to use a third propulsion energy.

Hybrid ferries, which in addition to the ship's diesel, also have batteries for propulsion, are becoming increasingly important. Scandlines is now going one step further and investing in Norsepower's wind propulsion technology on board the "Copenhagen". Norsepower's rotor sail is a modern version of a Flettner rotor - a rotating cylinder that uses the Magnus effect: When air flows past a rotating cylinder, a force is generated at right angles to it.

Since the ferry connection between Rostock in the south and Gedser in the north is almost at right angles to the wind, which mainly comes from the west, Copenhagen has very favorable conditions - in total, the carbon dioxide emissions of the ferry are to be reduced by four to five percent. The rotor sail is 30 m high and 5 m in diameter.
