British wind power to drive Maersk container ship
Rotor sails claimed to deliver fuel and emissions savings of 21%
Shipping company Maersk is exploring the use of a rotor sail technology developed by British firm Anemoi Marine Technologies to potentially reduce the fuel consumption and greenhouse gas emissions of its container ships. Anemoi will design and install a 5-meter diameter rotor sail, measuring 35 meters in height, on an 8,700 TEU (twenty-foot equivalent unit) Lima-class container ship, a vessel size typically smaller than rivals like MSC's Irina-class ships, which can carry 24,346 TEU.
The rotor sail, which utilizes the Magnus effect to generate lift and provide additional thrust, is set to be installed in mid-2027. Anemoi reports that ships equipped with three of its rotor sails achieved an average 9.1% reduction in net fuel and emissions during a year-long assessment, with some voyages reaching 21% savings. Anemoi CEO Clare Urmston expressed enthusiasm about collaborating with Maersk on this pioneering project, while Maersk's head of fleet technology, Ole Graa Jakobsen, emphasized the importance of testing wind-assisted propulsion technologies to improve vessel efficiency and reduce emissions in line with IMO's emission reduction targets for the shipping industry.
