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.

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.

“The installation of Anemoi’s Rotor Sails on NSU TUBARAO, one of the largest vessels in the global fleet, marks another significant step forward for sustainable shipping. It’s heartening to see industry leaders like NS United and Vale embracing innovative solutions to meet maritime’s environmental challenges,” CEO of Anemoi Marine Technologies, Kim Diederichsen said.
