Vale Partners With Asyad to Equip Sohar Max, Largest Ore Transport Ship, With Innovative Rotating Sails from Anemoi, Aiming for Efficiency and Emission Reduction.
Vale, a mining giant, has taken an innovative step towards sustainability by signing a contract with the shipping company Asyad from Oman to implement rotating sails on one of its Valemax ships. This vessel, known as Sohar Max, is already the largest ore transport ship in the world, measuring an impressive 362 meters in length, 65 meters in width, and capable of carrying up to 400,000 tons of cargo.
Vale Signs Partnership With Asyad for Implementation of Rotating Sails on Valemax
The revolutionary technology, developed by the English manufacturer Anemoi, is based on wind propulsion, providing substantial gains in energy efficiency and a notable reduction in emissions.
The expectation is that the adaptation of Sohar Max will be completed by the second quarter of 2024, marking the beginning of a testing period that promises to redefine sustainable navigation standards.

The five cylindrical rotors to be installed on the Valemax will be approximately 35 meters tall and 5 meters in diameter.
These dimensions represent double the sail area of the rotors used on Guaibamax, another Vale vessel with a capacity of 325,000 tons.
This expansion will allow for impressive efficiency gains, estimated at up to 6%, resulting in a significant reduction of up to 3,000 tons of CO2 equivalent per ship annually.
This is not Vale’s first foray into innovative technologies.
The Ecoshipping project, a Research and Development (R&D) initiative from Vale’s navigation division, has already included a series of agreements with Asyad for the implementation of advanced solutions.
Previous projects have included the use of silicone paint for reducing resistance, the installation of frequency inverters to decrease electricity consumption, and the employment of hydrodynamic devices to enhance propulsion.
Ecoshipping: Towards More Sustainable Maritime Transport
All these efforts align with the goals set by the International Maritime Organization (IMO) and aim to reduce Vale’s carbon emissions.
“Wind energy will play a central role in the decarbonization strategy for iron ore maritime transport”, states Vale’s Naval Engineering Manager, Rodrigo Bermelho.
The cylindrical rotors operate by spinning to create a pressure difference, propelling the ship forward through a phenomenon known as the Magnus effect.
This innovative technology allows for a reduction in the power and fuel consumption of the main engine when wind conditions are favorable, providing fuel savings while maintaining speed and travel time.
The installation of rotating sails on Sohar Max represents not only a milestone for Vale but a significant advance in the quest for sustainable solutions in maritime ore transport.
The success of this project will not only contribute to the company’s operational efficiency but also set a standard for the next generation of ships.
