As shipowners look for practical ways to reduce emissions today, retrofit technologies are becoming an increasingly important part of the decarbonisation conversation.

In less than two weeks, this will be the focus of Lloyd's Register Retrofit Research Programme panel, Retrofitting for the Future: Evaluating the Technologies Shaping Shipping's Transition, where Anemoi CEO Clare Urmston will join industry experts at SMM Hamburg.

Moderated by Manos Agaoglou, the session will explore the opportunities and challenges shaping retrofit investment decisions, with Clare sharing perspectives on the role of wind-assisted propulsion in supporting shipping's transition.

🌬️ How much carrying capacity do Anemoi Rotor Sails support?

According to the International Windship Association, more than 100 large commercial vessels are now equipped with wind propulsion technology, representing over 5 million DWT of cargo-carrying capacity.

Anemoi Rotor Sails have been installed across a growing fleet of vessels, with a range of deployment systems designed to suit different vessel types and operational requirements, helping shipowners harness wind power to reduce fuel consumption and emissions.

But how much cargo-carrying capacity do you think Anemoi's installed fleet represents?

🎙️ Green Shipping Corridors: Catalysts for Zero-Emission Fuels

With SMM just a few weeks away, we're looking forward to taking part in discussions at the Global Maritime Environmental Congress (gmec) as the industry continues to navigate the path towards decarbonisation.

Our CEO, Clare Urmston, will be sharing her insights during the industry panel alongside fellow industry leaders Gavin Allwright, Bo Cerup-Simonsen, Steve Esau, Jesse Fahnestock and Alexandros Karamitsos, exploring how green shipping corridors can support the maritime industry's transition to low and zero-emission fuels.

📅 Wednesday 2nd September 2026

🕒 3:00 PM – 3:50 PM

📍 Energy Efficiency Stage, Hall A4, SMM Hamburg

As the industry works towards meeting increasingly ambitious emissions targets, collaboration, innovation and the deployment of proven technologies will be essential.

Wind-assisted propulsion is already helping shipowners reduce fuel consumption and emissions today, while supporting the transition to the fuels of the future.

If you're attending SMM, do come and meet the Anemoi team at Stand 329, Hall A4 to discuss how Rotor Sail technology can support your fleet's efficiency and decarbonisation goals.

See you in Hamburg 👋

🌍 Interested in a graduate engineering role that's helping to decarbonise global shipping?

We're looking for a Graduate Engineer to join our growing team in London. This is far more than a traditional graduate design role. Working alongside experienced engineers, you'll gain exposure to a wide range of engineering activities while contributing to technology that's helping make shipping more sustainable.

At Anemoi, we're developing innovative Rotor Sail technology that helps vessels harness renewable wind power, reducing fuel consumption and emissions across the global shipping industry.

You'll also have opportunities to travel internationally, including supporting installations and commissioning activities on board ships.

If you're passionate about engineering, sustainability and solving real-world challenges, we'd love to hear from you.

⚙️ Turning wind into propulsion

At first glance, it looks surprisingly simple. A rotating cylinder mounted on the deck of a ship.

But behind that simple design is a century-old piece of physics helping modern vessels reduce fuel consumption and emissions.

As the Rotor Sail spins, wind flowing around the cylinder creates a pressure difference that generates thrust perpendicular to the wind direction. This phenomenon, known as the Magnus effect, provides additional forward propulsion to the vessel.

The result?

🌬️ Reduced engine load
⛽ Lower fuel consumption
📉 Reduced emissions

Where vessels are fitted with our folding deployment system, Rotor Sails can be lowered when required, helping maintain operational flexibility during port calls and cargo operations.

The principle may be over 100 years old, but its application is helping shipping navigate the challenges of decarbonisation today.

Simple in concept. Sophisticated in ex*****on.

With one month to go, we're getting ready for SMM 2026 in Hamburg ⚓🚢

From 1st–4th September 2026, the Anemoi team will be at SMM 2026, where we'll be showcasing how our Rotor Sails are helping shipowners achieve real, measurable fuel and emissions savings.

You can find us at Stand 329, Hall A4, where we'll be discussing how wind-assisted propulsion is helping the maritime industry accelerate decarbonisation and improve operational efficiency.

If you're attending SMM, be sure to stop by and say hello – we'd love to meet you.

The headlines this summer have been hard to ignore. Heatwaves. Extreme weather. New climate records.

But while the challenges are global, solutions often start with practical steps.

Shipping moves around 90% of world trade, and reducing its environmental impact won't come from a single breakthrough. It will come from lots of innovations working together.

Wind-assisted propulsion is one of them.

Our Rotor Sails harness a resource that's been powering ships for thousands of years: wind. By helping vessels reduce fuel consumption and emissions, we're making shipping more efficient using technology that's available today.

Not a future concept. A practical solution delivering results now.

Just smart engineering, proven physics, and Rotor Sails delivering real-world results. 🌬️

Eight years ago, we installed four Rotor Sails onboard M/V Afros.

At the time, the installation marked an important early milestone for wind-assisted propulsion. Today, the experience gained from that vessel continues to influence the much larger and more advanced systems we are delivering across the industry.

The Afros has now operated across global trading routes for nearly a decade. More than 150 voyages. More than 200 port calls. More than 117 ports visited.

And throughout that time, the Rotor Sails have continued operating reliably alongside everyday vessel operations, port activities and chartering requirements.

That long-term operational experience has allowed us to refine our technology, optimise deployment systems and continue scaling our Rotor Sail performance, with today’s systems delivering fuel savings exceeding one tonne per Rotor Sail, per day.

The Afros may have started with an earlier generation installation, but it has provided something incredibly valuable: real operational proof.

From an early Rotor Sail concept to Anemoi Rotor Sails installed on vessels representing more than 1.8 million DWT of cargo-carrying capacity. 🚢

A lot has happened since the first Rotor Sail concepts were explored in 2007.

The timeline below highlights some of the key milestones in Anemoi's journey, from early Rotor Sail development and testing to our first commercial installations, expanded production capabilities and a growing global fleet.

Today, 29 Anemoi Rotor Sails have been delivered, with a further 10 in production and additional orders on the way.

We're looking forward to continuing to support the shipping industry's transition to wind-assisted propulsion.

More exciting milestones are to come. 👀

Anemoi Marine Technologies has been awarded design assessment certificates from Bureau Veritas covering several versions of its Rotor Sail technology, further reinforcing a growing track record of independent industry validation.

The latest approvals cover fixed and rail deployed 3.5m x 24.5m Rotor Sails, including EX-rated versions and shorter variants designed for vessels with air draft restrictions.

Together with approvals from Lloyd's Register, DNV, ABS and ClassNK, the entire Anemoi Rotor Sail portfolio is now covered by approvals from leading classification societies, providing shipowners and operators with greater confidence in the technology while helping to reduce project risk and simplify deployment.

By securing approvals across multiple leading class societies, Anemoi is helping to reduce barriers to the adoption of Rotor Sail technology across both newbuild and retrofit projects.
