Rotor Sails, also referred to as Flettner Rotors, consist of vertical cylinders that harness the wind's renewable power to propel ships when powered to rotate. The aerodynamic phenomenon known as the Magnus Effect is capitalized on by these highly efficient mechanical sails to provide additional thrust to vessels and provide substantial fuel and emission savings.

Under the agreement signed on 22 October, Wärtsilä will completely incorporate the Rotor Sails of Anemoi Marine Technology into its Propulsion Business, providing a new construction and retrofit solution for most types of vessels, but initially concentrating on bulk carriers and tankers.

"As the industry focuses on emission reduction targets and energy saving, we are collaborating with Wärtsilä to strengthen our offering and facilitate the global uptake of our Rotor Sails by offering clients a full end-to-end solution including sales, supply and lifecycle support,” stated Kim Diederichsen, CEO of Anemoi Marine Technologies.

Wärtsilä said it would further promote compliance with the Energy Efficiency Design Index (EEDI) of the IMO by providing wind propulsion solutions as part of the propulsion offering, thus adding to the company's efforts to improve fuel efficiency and minimize emissions.
