TEST RUN COMPLETED FOR ROTOR SAIL ON FINNISH RO-PAX

TEST RUN COMPLETED FOR ROTOR SAIL ON FINNISH RO-PAX

Friday, April 23, 2021 

Viking Line of Finland has, for the past three years, been testing rotor sail technology developed by the Finland-based clean tech company Norsepower onboard the LNG-fuelled ro-pax vessel 'Viking Grace'.

The rotor sail generates thrust through the so-called Magnus effect, reducing the vessel’s need for propulsion force. Viking Grace was the first passenger ship to be equipped with a rotor sail, and the trial period has now been completed. Viking Line intends to continue testing new climate-smart solutions on its vessels. The new Viking Glory has already been equipped for the possible use of a rotor sail.

“Rotor sail technology is a promising and ambitious step towards more environmentally-friendly maritime transport. It is important to develop this kind of solution, and we certainly want to be involved in finding new ways to make Baltic Sea transport more climate-smart. Flettner rotor technology is very interesting. Our partnership with Norsepower has been enriching and has expanded our views,” said Johanna Boijer-Svahnström, SVP Corporate Communications, Viking Line.

Norsepower’s rotor sail is fully automated to detect situations in which wind conditions are favourable for its operation. The system then starts up the sail automatically, with no user input needed. Norsepower’s rotor sail has been installed on four other vessels in addition to Viking Grace, including Scandline’s ferry Köpenhamn, which runs between Germany and Denmark, and the tanker Maersk Pelican.

”Test results from the Viking Grace project, which were validated by independent parties, led to many new rotor sail deliveries, and our operations are growing rapidly. The rotor sails that have been optimised for new vessels could potentially achieve fuel savings of up to 20%. Our rotor sail technology is already available as a solution enabling significantly lower emissions in maritime transport,” said Tuomas Riski, Norsepower CEO.
