Thanks to an agreement with the Danish shipping company Maersk Line, the wind propulsion systems developed by the British Anemoi Marine Technologies Ltd. will also apply to the container ship segment. The Rotor Sail System of the London-based company, in fact, will be installed on a 8,700 container ship of the "Maersk Lima" class with the objective of increasing the energy efficiency of the ship and reduce its emissions. The installation of the rotating sail, which it will have a diameter of five meters and will be 35 meters high, is scheduled for the middle of next year.

Rotating sails are a wind propulsion technology that uses aerodynamic lift to generate additional thrust, helping to reduce fuel consumption and related emissions under proper operating conditions. Anemoi, which is Founded in 2015, it has so far installed its own system Rotor Sail on different types of ships, mainly including bulk carrier. The company points out that each Rotor system Sail allows a saving of about one ton of fuel per day and about three tons of CO2 emissions.
