Setting the world in motion with wind: Anemoi Rotor Sails

Anemoi Marine Technologies (Anemoi) was born from a shipping professional’s desire to minimise the impact ships have on the environment. To this day, our mission is to accelerate the maritime industry’s transition to zero emission shipping by delivering market-leading wind technology.

Rotor Sails, also known as Flettner Rotors, were first installed on a vessel over 100 years ago. These modern mechanical sails are comprised of tall cylinders which, when driven to spin by a motor, harness the renewable power of the wind to provide auxiliary propulsion to vessels, which significantly reduces fuel consumption and lowers harmful emissions entering our atmosphere by 5-30%.

Anemoi’s proven technology has been uniquely designed to work alongside complex vessel operations, making it suitable for most ship types (both retrofit and newbuild). As other energy-saving devices and alternative fuels become market-ready, Anemoi Rotor Sails can be used in conjunction to achieve enhanced environmental benefits.
