Since 2013, Scandlines has actually spent greater than EUR 300 million in structure and also transforming traditional ferryboats right into crossbreed ferryboats. In 2020, the ferryboat driver included eco-friendly wind propulsion innovation to the listing of environment-friendly campaigns by setting up a Norsepower Rotor Sail on the crossbreed ferryboat Copenhagen, which operates the Rostock-Gedser path in between Germany and alsoDenmark With the Rotor Sail from Finnish Norsepower, Scandlines has actually lowered carbon dioxide exhausts from the crossbreed ferryboat by approximately 4% and also, on great days with ideal wind problems, by as high as 20%.

The Rotor Sail– a 30m high revolving cyndrical tube– is a modern-day variation of the Flettner blades and also the innovation is based upon the Magnus result. When wind satisfies the rotating Rotor Sail, the air movement speeds up on one side of the Rotor Sail and also decreases on the contrary side. The modification in the rate of air movement leads to a stress distinction, which produces a lift pressure that is vertical to the wind circulation instructions.

This lift pressure permits Scandlines to decrease making use of diesel motor and also for that reason minimizes both the gas usage and also linked exhausts.

The innovation has the maximum result when there is a wind blowing 20 m/s a little abaft abeam and also the wind is vertical to the sail. The path in between Gedser to the north and also Rostock to the south is practically vertical to the dominating wind from the west (or a bit much less often eastern) providing Scandlines beneficial problems for making use of Rotor Sails on the going across.

Michael Guldmann Petersen, COO, Scandlines claimed: “After positive experiences with the Rotor Sail on the Scandlines hybrid ferry Copenhagen, Scandlines had prepared the sister ferry Berlin for a Rotor Sail as well. We are happy to see, that the installation was successfully completed and that the ferry went into operation again this morning as planned.”

On 16 May 2022, Scandlines mounted the Norsepower Rotor Sail on M/V Berlin in the port of Rostock while the ferryboat ran out solution for a couple of hrs.

Tuomas Riski, CHIEF EXECUTIVE OFFICER, Norsepower discussed the current setup: “Scandlines is taking the international GHG emissions reductions targets extremely seriously and is demonstrating a leading approach to investing in innovation to supersede these. Expanding its use of our Rotor Sail technology on its second vessel highlights the viability of wind power, and the significance of the emissions savings which can be achieved.”

The Norsepower Rotor Sail remedy is completely automated. The system gauges the wind rate and also instructions and also based upon these dimensions computes whether use the Rotor Sail will certainly decrease exhausts. If so, the Rotor Sail begins immediately. However, for details port locations which are not ideal for Rotor Sail usage, the Rotor Sail remedy has setups to make certain the innovation will certainly not be triggered.
