Anemoi Rotor Sails Boost NSU Tubarao Fuel Efficiency for Vale

Anemoi Marine Technologies has successfully completed the installation of five advanced **Anemoi Rotor Sails** on the NSU Tubarao, a massive 400,000-deadweight tonne (DWT) ore carrier. This significant retrofit project, undertaken during scheduled drydocking in China, is set to drastically improve fuel efficiency for the Vale-chartered vessel, which primarily transports iron ore. This initiative underscores a strong commitment to sustainable shipping practices within the global bulk carrier fleet.

Enhancing Wind-Assisted Propulsion for Bulk Carriers

The NSU Tubarao, owned and operated by NS United Kaiun Kaisha, is one of the world’s largest bulk carriers. The five Rotor Sails, each towering 35 meters high and 5 meters in diameter, were strategically installed with a tilting mechanism. This innovative design provides operational flexibility crucial for cargo handling on such large vessels. This project marks Anemoi’s fourth successful retrofit of very large ore carriers (VLOCs) operating under Vale charters, significantly expanding the reach of wind-assisted propulsion technology.

Driving Sustainable Shipping & Fuel Reduction

The implementation of this cutting-edge wind-assisted propulsion technology on the NSU Tubarao is projected to yield impressive results. Experts anticipate an annual fuel consumption reduction of between 6% and 12%. This substantial saving not only lowers operational costs but also significantly reduces greenhouse gas emissions, aligning with growing industry demands for decarbonization. Anemoi’s continued advancements in marine technology are paving the way for a greener future for the maritime sector, offering tangible environmental benefits and demonstrating a clear path towards more sustainable global trade.
