FAST INSTALLATION FOR NORSEPOWER ROTOR SAIL ON SCANDLINES FERRY

Tuesday, May 26, 2020 

Norsepower has announced the successful installation of a 30m high Rotor Sail on board the Scandlines hybrid ferry ‘ Copenhagen’ during the ferry's scheduled overnight stop.

The Copenhagen, a hybrid passenger ferry operating between Rostock, Germany and Gedser, Denmark, was retrofitted with a Norsepower Rotor Sail unit measuring 30m in height and 5m in diameter. The installation was completed in a few hours, following meticulous preparation over the past few months.

The Norsepower Rotor Sail is a modernised version of the Flettner rotor, a spinning cylinder that uses the Magnus effect to harness wind power to provide forward thrust. The installation, the fourth successfully completed by Norsepower, is estimated to reduce emissions by an estimated 4-5% on average without compromising pre-retrofit speed and voyage times.

Tuomas Riski, CEO, Norsepower, said: “We are delighted to announce this latest successful installation of the Rotor Sail, which demonstrates that retrofitting can be achieved without any interruption and downtime to day to day commercial operations. Scandlines has a strong track record of investing in new clean technologies that save emissions onboard its fleet. The addition of Norsepower’s Rotor Sail makes the Copenhagen one of the world’s most energy-efficient ferries. With increasing international regulatory and public pressure on the maritime industry to decarbonise, it is essential for the industry to recognise the value of one of the oldest forms of propulsion - wind. The market for wind propulsion is increasing, and this installation demonstrates how combining all methods of vessel optimisation is key to broader progress.”

Scandlines CEO, Søren Poulsgaard Jensen, said: “We see huge value in investing in technology with the ultimate goal of reducing emissions. Working with Norsepower on this innovative solution was a perfect fit with our values and ambitions regarding sustainable shipping. On our modern, hybrid ferry, this solution will sit alongside hydrodynamic hull optimisation, and a hybrid electric propulsion system with a battery powered energy storage system, improving not only our efficiency but also profitability. We look forward to seeing the instant benefits of this technology.”

The Rotor Sail is claimed to be the first data verified and commercially operational auxiliary wind propulsion technology for the maritime industry. It is fully automated and detects whenever the wind is strong enough to deliver emission savings, at which point the Rotor Sails start automatically.
