A bulk carrier vessel equipped with Anemoi Marine Technologies’ rotor sails has concluded its first voyage from China to Western Australia, following the successful installation of the rotor sails in Chengxi Shipyard, China, in June 2023.
The TR Lady, an 82,000 dwt Kamsarmax bulk carrier, was retrofitted with three 5×24m Rotor Sails by Anemoi. The vessel is owned by TR Lady Shipping Ltd, a portfolio company of Tufton Investment Management Ltd and is on a time charter with Cargill Ocean Transportation.
During the first voyage, Anemoi engineers sailed with the vessel for sea acceptance testing and trials, with positive initial performance results which suggest that TR Lady can see average annual fuel and emissions savings of up to 10%, exceeding the original expectations. The performance of the Rotor Sails will continue to be monitored over the coming months.
The rotor sails were installed on Anemoi’s unique and patented transverse rail deployment system. This system enables the sails, which are fixed to the centre line during voyages, to be moved port or starboard when berthed for cargo operations, meaning loading and unloading can continue without being obstructed. Class approvals have been awarded by Lloyd’s Register.
Rotor Sails, also known as ‘Flettner Rotors’, are vertical cylinders which, when driven to rotate, harness the renewable power of the wind to provide additional forward thrust. These highly efficient mechanical sails capitalise on the aerodynamic phenomenon known as the Magnus Effect and will deliver significant fuel and emission savings to TR Lady.
