Scandlines operates the world's largest fleet of hybrid ferries, which combine diesel and battery power. Installation of one 30x5 Rotor Sail reduces the emissions of the hybrid ferry M/V Copenhagen even further. Sailing between Rostock (DE) and Gedser (DK), the wind conditions are expected to be favourable for wind propulsion.
Søren Poulsgaard JensenCEO, Scandlines
By installing a Rotor Sail, we can reduce CO2 emissions on the Rostock-Gedser route by four to five per cent.

Route: Turku, Finland – Stockholm, Sweden Trial period: 2018 to 2021, Norsepower Rotor Sail 24x4 M/S Viking Grace is one of the most environmentally friendly cruise ferries in the global maritime industry. With the addition of Norsepower’s technology, the vessel was able to further reduce its emissions, fuel burn, and fuel costs; reducing carbon emissions by circa 900 tonnes annually; equivalent to cutting 300 tons of LNG fuel per year, making it the first-ever global LNG/wind electric propulsion hybrid ship. During the first year of operation, measurement campaign was conducted to confirm the long term fuel saving potential. The work of three independent reasearch parties, ABB, Chalmers University, and NAPA was complimented with Norsepowers own force measurement analysis. It was confirmed that the Rotor Sail reduces power consumption between 207-315 kW equalling 231-315 tons of fuel every year, well inline with original target of the project. More detailed information on the campaigns is available here The project was supported by Horizon 2020 program of the European Commission and the Rotor Sail was removed in 2021 after a successful fixed-term trial period.
