Japanese shipowner NS United Kaiun Kaisha, Ltd. (NSU) and Vale International SA (Vale:) have reached an agreement to install rotor sails (H:35m x D:5m x 5 units) manufactured by Anemoi Marine Technologies Ltd. (Anemoi) on 400,000dwt VLOC, NSU TUBARAO, which has been engaged in a long-term transportation contract between NSU and Vale since its delivery in September 2020.
The 361m-long and 65m-wide NSU TUBARAO was completed in 2020 and has been leased to Vale for long-term transport operations since September 2020.The installation of the rotor sails on the ship is scheduled around September 2025.
A rotor sail is a device to obtain propulsion by using the pressure difference generated around a cylinder by rotating a cylindrical sail installed on the deck. It is expected to reduce fuel consumption and CO2 emissions from the Ship by approximately 6~12%
NSU has been actively working to make their vessels more efficient and reduce their greenhouse gas (GHG) emissions through the introduction of energy-saving devices such as rotor sails and by transitioning to ships powered by next-generation fuels.
