Anemoi is a global provider of
proven wind technology, driving a
more sustainable future for the
shipping industry

Driven by invention and motivated by environmental protection, we support the winds of change.

Our mission

Every year the shipping industry releases almost a billion tonnes of CO2 into the atmosphere. Like many other organisations in the industry, Anemoi would like to see this figure reduced dramatically and one day removed all together. To achieve this goal, industry parties need to join forces to develop and adopt emission reduction solutions.

Anemoi Rotor Sails can reduce emissions by up to 30% and, with our patented Deployment Systems, be installed on most merchant vessels. Our mission is to accelerate the maritime industry’s transition to zero emission shipping by delivering market-leading wind technology.

The history of Anemoi


Our Rotor Sail story begins with a group of industry professionals. Having witnessed first-hand the rising emissions caused by shipping, they set out to develop a technology that would provide a more sustainable future for the industry. Various technologies were assessed during this period.

Rising Emissions

Rising Emissions


Following technology evaluation, Flettner Rotors demonstrated the most potential and were selected for further development.

R&D of the Rotors involved wind tunnel and scale model testing. The full-scale proof of concept took place in 2009.

Research & Development

Research & Development


Anemoi built its full-scale test facility in the UK with a highly instrumented prototype with our patented Folding Deployment System. This testing facility harvests valuable data to verify thrust performance and is an R&D hub for continual development and optimisation.

Following successful technology development and prototype testing, Anemoi Marine Technologies Ltd. was incorporated after the firm support and vision to install our Rotor Sails on board globally trading commercial vessels.


Candidate vessel, m/v Afros, was selected for the pilot installation, leading to the development and production of Anemoi’s Rotor Sails with patented Rail Deployment Systems.

Another candidate vessel, m/v Axios, was selected for ‘Wind Ready’ integration.

Product certification from Class was achieved for Anemoi Rotor Sails.

Class plan approval and vessel integration work for both the m/v Afros and m/v Axios was completed with longitudinal and transverse Rail Deployment respectively.


The m/v Afros was delivered with 4 Rotor Sails and Rail Deployment. The vessel set sail on her maiden voyage from China to Australia. This was the first installation on a Dry Bulk Carrier and went on to win numerous international industry awards.

After successful sea testing of Rotor Sail performance and operations, Anemoi’s growth has continued with the development of its senior management team, with a focus on commercialising the technology and go-to-market strategy.


Following significant market interest from owners and key industry stakeholders, Anemoi is continually expanding as we prepare for volume production and technology roll out, while optimising the performance and cost-efficiency of our product portfolio.

A sustainable future of shipping

A sustainable future of shipping


Shipping faces critical challenges now and in the near future. The International Maritime Organisation’s Strategy on Reduction of GHG Emissions from Ships is net zero emissions by or around 2050.

Rotor Sails, a proven renewable technology in the shipping space, can help achieve reduction targets, today.
