Ferry operator Scandlines has signed an agreement with Norsepower Oy to install the company’s Rotor Sail Solution onboard the hybrid passenger ferry, M/V Copenhagen.

Operating between Rostock in Germany and Gedser in Denmark, the M/V Copenhagen operates using diesel and battery power. The vessel will reduce its fuel consumption and emissions by a further four to five per cent by using the Rotor Sail Solution to harness wind power.

The technology is the first data-verified and commercially operational auxiliary wind propulsion technology for the maritime industry. When wind conditions are favourable, it enables the electric propulsion thrusters and centre propel 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 Gedser to the north and Rostock to the south is almost perpendicular to the prevailing wind from west, giving Scandlines favourable conditions for using Rotor Sails on the ferry crossing.

Since 2013, Scandlines has invested more than EUR 300 million in building and retrofitting ferries from conventional diesel-driven to hybrid ferries.

Preparations for the retrofit will take place in November 2019 with the installation scheduled for Q2 2020. M/V Copenhagen is set to be retrofitted with one large-sized Norsepower Rotor Sail unit that is 30m in height and 5m in diameter.

“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.

Tuomas Riski, CEO, Norsepower, stated: “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.”

“NABU welcomes Scandlines’ various efforts towards sustainable shipping. With rotors besides hybrid drives, the company sets new standards in terms of integrating different technical solutions to mitigate especially climate and air pollution emissions. To reach the Paris climate goals, more corporate responsibility by other shipping companies is needed,” says Malte Siegert, head of environmental policy at NABU, the German Nature and Biodiversity Conservation Union.
