NS United to install anemoi rotor sails on Valemax VLOC

NS United Kaiun Kaisha and Brazilian mining company Vale International SA have agreed to install rotor sails manufactured by Anemoi Marine Technologies on 400,000dwt-type Valemax VLOC, NSU Tubarao.

“We’re delighted to be partnering with NS United Kaiun Kaisha, Ltd. (NSU) and charterer Vale to install five folding rotor sails on a 400k dwt Valemax VLOC,” Anemoi said on Thursday in a social media post.

The vessel has been engaged in a long-term transportation contract between NSU and Vale since its delivery in September 2020.

As informed, 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%.

The five rotor sail units which will be used on this vessel will be 35m high and 5m in diameter.
