Scandlines opts for Rotor sails on second ferry after successful trials

Scandlines repeats Rotor Sail order following successful, proven results on Copenhagen.

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. Berlin also operates on the Rostock-Gedser route but, unlike Copenhagen, is flagged in Germany.

When Scandlines decided to install a Rotor Sail on Copenhagen in 2019, the decision was based on technical data from the provider Norsepower, a few other shipping companies’ experiences as well as its own studies and calculations. The Norsepower Rotor Sail was then installed in May 2020.

Scandlines’ COO, Michael Guldmann Petersen, commented, “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.”

The route between Rostock and Gedser is perfectly 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 30 metres into the air, on the other hand, is a very 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 of 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 which it 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.
