- The technology has the optimum effect when there is a wind blowing 20 m/s a little abaft abeam and the wind is perpendicular to the sail.
- On 16 May 2022, Scandlines installed the Norsepower Rotor Sail on M/V Berlin in the port of Rostock while the ferry was out of service for a few hours.
- The Norsepower Rotor Sail Solution is fully automated.
Scandlines has set higher goals for itself than the Paris Agreement, aiming to be emission-free by 2040. The installation of a Norsepower Rotor Sail on the Scandlines hybrid ferry M/V Berlin is the next step as reported by Norse Power.
Hybrid ferries
Since 2013, Scandlines has invested more than EUR 300 million in building and converting conventional ferries into hybrid ferries.
In 2020, the ferry operator added environmentally friendly wind propulsion technology to the list of green initiatives by installing a Norsepower Rotor Sail on the hybrid ferry Copenhagen, which operates on the Rostock-Gedser route between Germany and Denmark.
The Rotor Sail – a 30 m high rotating cylinder – is a modern version of the Flettner rotor and the technology is based on the Magnus effect.
When the wind meets the spinning Rotor Sail, the air flow accelerates on one side of the Rotor Sail and decelerates on the opposite side.
This lift force allows Scandlines to reduce the use of diesel engines and therefore reduces both the fuel consumption and associated emissions.
Fully automatic
The technology has the optimum effect when there is a wind blowing 20 m/s a little abaft abeam and the wind is perpendicular to the sail.
On 16 May 2022, Scandlines installed the Norsepower Rotor Sail on M/V Berlin in the port of Rostock while the ferry was out of service for a few hours.
“Expanding its use of our Rotor Sail technology on its second vessel highlights the viability of wind power and the significance of the emissions savings which can be achieved.”
The Norsepower Rotor Sail Solution is fully automated.
The system measures the wind speed and direction and based on these measurements calculates whether the use of the Rotor Sail will reduce emissions.
If so, the Rotor Sail starts automatically.
