Scandlines installs rotor sail on board ferry
Scandlines has signed an agreement with Norsepower Oy Ltd, leading clean technology and engineering company pioneering modern wind propulsion technology, to install Norsepower’s Rotor Sail Solution on board the M/V Copenhagen, a hybrid passenger ferry.
Operating between Rostock in Germany and Gedser in Denmark, the M/V Copenhagen belongs to
the world’s largest fleet of hybrid ferries, which combines diesel and battery power. Since 2013,
Scandlines has invested more than EUR 300 million 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.
The Norsepower Rotor Sail Solution is a modernised version of the Flettner rotor – a spinning
cylinder that uses the Magnus effect to harness wind power to thrust a ship. It is the first dataverified and commercially operational auxiliary wind propulsion technology for the global maritime industry. When wind conditions are favourable, it enables the electric propulsion thrusters and center 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
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,” says Scandlines CEO Søren Poulsgaard Jensen.
NABU, the German Nature and Biodiversity Conservation Union, is pleased with Scandlines’
decision to further reduce CO2 emission:
“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.
Commenting on the deal, Tuomas Riski, CEO, Norsepower says: “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.”
