Anemoi to retrofit rotor sails on NSU Tubarao

Rotor sails enhance propulsion by rotating cylinders to exploit aerodynamic pressure differences, providing a significant boost in fuel efficiency. The sails can fold onto the deck in minutes, allowing for unimpeded port operations and crane access.
The move aligns with NSU's broader strategy of improving fleet efficiency and lowering greenhouse gas emissions through energy-saving technologies and the exploration of next-generation fuels. Vale, while not the vessel's owner, will benefit from reduced scope 3 emissions in its value chain, contributing to its 2035 target of a 15% reduction in these emissions, partly driven by its Ecoshipping R&D program.
The installation reflects a growing trend in the maritime industry, where wind-assisted propulsion is gaining traction. Recent developments include MOL's LNG carrier project and BAR Technologies' deal to outfit 34 ships with rigid sail technology.
