Ferry operator Scandlines has announce that it has signed an agreement with Norsepower to install a Rotor Sail on board the hybrid passenger ferry Copenhagen.
Operating between Rostock in Germany and Gedser in Denmark, the Copenhagen belongs to the world’s largest fleet of hybrid ferries. Since 2013, Scandlines has invested more than €300m in building and retrofitting ferries from conventional diesel-driven to hybrid ferries. With the addition of Norsepower’s technology, the vessel will further reduce its emissions.
Preparations for the retrofit will take place in November 2019 with the installation scheduled for Q2 2020. Copenhagen is set to be retrofitted with one large-sized Rotor Sail unit that is 30m in height and 5m in diameter.
The Norsepower Rotor Sail Solution is a modernised version of the Flettner rotor. When wind conditions are favourable, it enables the electric propulsion thrusters and centre propeller to be throttled back, reducing emissions – while providing the power needed to maintain speed and voyage time. Because it generates supplementary thrust from wind, the solution is compatible with all other emissions saving technologies. The route between Gedset and Rostok has the most favourable prevailing wind direction and conditions for employing the rotor.
“By installing a Rotor Sail, we can reduce CO2 emissions on the Rostock-Gedser route by four to five per cent,” said Scandlines CEO Søren Poulsgaard Jensen.
Commenting on the deal, Tuomas Riski, CEO, Norsepower said, “As a leading clean technology and engineering company, we are proud to be partnering with Scandlines as we work towards a modern era of auxiliary wind propulsion for the global maritime fleet, while supporting shipping’s transition to a low-carbon future.”
