The Norsepower Rotor SailTM made of lightweight and strong composite material and with a fully automated control system, produces thrust as the wind generates differential pressure around the slewing rotor while the vessel is sailing. By applying this solution, the vessel is expected to achieve about 6-10% fuel and GHG emissions reductions, combined with voyage optimisation technology – enabling significant advancements towards decarbonisation goals and reducing fuel consumptions.

MOL and VALE will continue to work towards both the stable transportation of iron ore and the reduction of GHG emissions.
