Anemoi Marine Technologies completed the installation of five Rotor Sails onboard the 400,000 dwt Very Large Ore Carrier (VLOC), Sohar Max, making it the largest vessel to receive wind propulsion technology to date. Sohar Max is a first generation Valemax, built in 2012 in China’s Rongsheng shipyard.
The project showcased global collaboration between Brazilian mining giant Vale S.A., Omani shipowner Asyad and UK-based Rotor Sail provider Anemoi.
The five 35 m tall, 5 m diameter Rotor Sails were retrofitted onboard Sohar Max at the COSCO Zhoushan shipyard in China, in October 2024. In addition, Anemoi has installed its bespoke folding deployment system, which will enable to sails to be folded from vertical to mitigate any impacts on the vessel’s cargo handling operations.
With the installation of the Rotor Sails, it is expected that Sohar Max will now be able to reduce its fuel consumption by up to 6% and cut carbon emissions by up to 3,000 tonnes annually. Sohar Max has just completed a voyage to Tubarao, during which the rotor sail test period began and testing will continue on future voyages.
We extend our deepest thanks to all our partners who made this retrofit possible. Together, we’re advancing meaningful change and driving the industry towards a greener future.
In October 2024, Vale announced it is also set to install Anemoi’s Rotor Sails onboard the 400,000 dwt VLOC NSU Tubarao, which is owned by NS United Kaiun Kaisha. The project, which is due for completion in September 2025, is expected to achieve significant reduction of fuel consumption and carbon emissions.
These projects with Vale are the latest in a series of ongoing installation projects Anemoi has with some of the world’s biggest shipowners and operators, which are looking to harness wind energy to increase the efficiency of their vessels by reducing fuel consumption and carbon emissions.
Rotor Sails are being increasingly embraced by shipowners who are aiming to achieve net-zero emissions and enhance the energy performance of vessels. Rotor Sails are a compact technology that offer a large thrust force to propel ships, helping them comply with pivotal international emission reduction benchmarks such as CII and EEDI/EEXI.
