Wind rotor installed on ship – Additional propulsion system should reduce fuel consumption on the sea

Leer, 23 April 2021 | During the docking of the multi-purpose freighter MS “Annika Braren”, the latest addition to the Rörd Braren ship management fleet, a wind assistance rotor sailing system was installed by Eco Flettner company in Leer.

The planning of the shipbuilding measures and the construction of the new rotor for the 86 m long and 15 m wide ship with a load capacity of 5 035 tdw took twelve months to complete.

The new rotor cylinder measures 18 m in height and 3 m in diameter. Large end plates with a diameter of 6 m are installed at the top and bottom of the cylinder. The “sailing machine” weighs approx. 27 t.

The Braren shipping company is taking part in the EU project WASP (Wind Assisted Ship Propulsion) by retrofitting the “Annika Braren”. It is financed through an “Interreg” program for the North Sea region.

“We are very pleased that the rotor is ready for on-board use and look forward to many more installations of our rotors in the future,” explains Ralf Oltmanns, Managing Director of Eco Flettner GmbH.

The managing director of Rörd Braren Bereederung, Anna Braren, adds: “This is an important project for our company and we are very proud that the ship is starting its maiden voyage with wind support.”
