SCANDLINES TO FIT NORSEPOWER ROTOR SAIL TO SECOND RO-PAX

SCANDLINES TO FIT NORSEPOWER ROTOR SAIL TO SECOND RO-PAX

Thursday, October 14, 2021 

Following the successful installation of the Norsepower Rotor Sail on the hybrid ferry 'Copenhagen' in 2020, and a year of demonstrated results, Scandlines has prepared the sister ferry Berlin for its own Rotor Sail installation.

When Scandlines decided to install a Rotor Sail on Copenhagen, the decision was based on technical data from Norsepower and other shipping companies’ experiences as well as its own studies and calculations. The Norsepower Rotor Sail was installed in May 2020. Now, Scandlines has had more than a year to collect data on how the Rotor Sail works on Copenhagen, and what effect it has on the route between Rostock to the south and Gedser to the north.

Scandlines’ COO, Michael Guldmann Petersen, said: “We expected the Copenhagen Rotor Sail to provide a 4% - 5% CO2 reduction. That expectation has been met, so we have now taken the next step and prepared the sister ferry Berlin for installation.”

Both ferries operate on the Rostock-Gedser route but, unlike Copenhagen, the Berlin sails under the German flag. The route is considered well located to meet the requirement that gives the greatest benefit of the Rotor Sail for propulsion, namely that the wind must be perpendicular to the sail.

“Our route across the Baltic Sea is north/south bound, and the prevailing wind is from the west or east. In other words, our Rotor Sails have optimal conditions,” said Petersen.

Several of Scandlines’ other green initiatives on the way to emission-free ferries are not visible to the outside world, as they are below the water surface. A Rotor Sail that protrudes 30m into the air, on the other hand, is a clear signal of a green vision.

“There has generally been a lot of interest in the Rotor Sail – and in the beginning even wonder among the passengers about the ‘chimney.’ Most of the crew are now also masters of technical explanations that are easy to understand,” said Petersen. 

Tuomas Riski, CEO Norsepower, said: “We are delighted that Scandlines is expanding its use of our Rotor Sail technology after achieving its CO2 emissions reduction targets on its first vessel, the Copenhagen. Our Rotor Sail technology is technically applicable to approximately 30,000 vessels in the current global fleet of ships and we hope that this is a further signal to ship owners and operators that confidence is growing in wind propulsion technology.” 

The preparation for the Rotor Sail includes building a steel foundation on the ferry, on which the Rotor Sail will be fixed. The initial work took place when the Berlin was on a planned yard stay at Remontowa in Poland at the end of May. The installation of the Rotor Sail itself is scheduled for 2022.
