MOL AND VALE TO STUDY BULKER ROTOR SAIL RETROFIT

MOL AND VALE TO STUDY BULKER ROTOR SAIL RETROFIT

Tuesday, November 2, 2021 

Mitsui OSK Lines (MOL) has signed an agreement with iron-ore mining giant Vale International to conduct a joint study on installation of a 'Rotor Sail' wind propulsion system on a 200,000 dwt bulk carrier, currently transporting iron ore for steel production, with the goal of reduction of GHG emissions from the vessel while underway.

The Rotor Sail produces propulsive force as the wind generates differential pressure around the slewing rotor while the vessel is underway. It offers high efficiency because the natural energy of the wind directly propels the vessel rather than being converted in to electricity.

The joint study team will examine and verify the number of Rotor Sails to be installed and the effect of GHG reduction, working closely with Anemoi Marine Technologies the manufacturer of the Rotor Sail. UK-based Anemoi installed the first Rotor Sail on a newbuilding Ultramax bulk carrier in 2018.

The MOL Group is implementing five initiatives to realise the mid-to-long-term targets set out in its Environmental Vision statement. This opportunity will pursue the initiative 'Enhancement of Energy-Saving Technologies', to reduce GHG emissions, with the goal of achieving net zero GHG emissions by 2050.
