Anemoi Marine Technologies has marked a major milestone. M/V Afros , the world’s first bulk carrier fitted with Anemoi rotor sails, has successfully completed its second intermediate survey after more than eight years of continuous operation. Carried out by Lloyd’s Register at Jiangsu Watts Energy & Engineering in Qidong, China, last month, the survey confirmed that the vessel’s four rotor sails remain structurally sound and free of operational issues, providing independent verification of the long-term durability and reliability of Anemoi’s rotor sails over an extended operational lifecycle. Installed in January 2018 on-board the 64,000 DWT geared Ultramax bulk carrier, owned by Blue Planet Shipping, the system has since provided eight years of real-world evidence that wind-assisted propulsion systems (WAPS) can deliver sustained fuel savings, emissions reductions and high operational availability in everyday commercial service. Anemoi says that the Afros ‘s eight-year milestone is one of the most significant long-term operational proof points yet achieved in the WAPS sector, demonstrating that rotor sails can perform reliably across a vessel’s lifecycle while integrating seamlessly into standard trading patterns. Op-Ed: Rotor sails and the race to decarbonize “The successful completion of Afros ’ second intermediate survey is a landmark moment not only for Anemoi, but for the wider wind propulsion sector.,” said Nick Contopoulos , co-founder and chief commercial officer at Anemoi. “Independent confirmation from Lloyd’s Register after more than eight years of operation demonstrates that Anemoi rotor sails are not simply an innovative decarbonization concept, they are a durable, practical and commercially deployable technology for the global fleet. This level of long-term operational validation significantly reduces uncertainty for shipowners considering wind-assisted propulsion and reinforces the role rotor sails can play in improving vessel e
