Decade of Wind Propulsion


International Windship Association and it’s 150+ members have declared the period 2021-2030 as the “Decade of Wind Propulsion”, a decade of delivering wind propulsion installations, optimising the technology solutions and helping to facilitate a quicker, deeper and ultimately cheaper transition to a fully decarbonised fleet. Press Release – Driving the Decade of Wind Propulsion 

Open Letter – A Level Playing Field Needed in Shipping Decarbonisation
Over 90 maritime companies, shipowners, designers and technology providers all involved with wind propulsion have come together to release this open letter, calling for maritime industry decision-makers and the shipping community to fully assess and utilise all available power solutions that deliver the necessary deep/swift cuts in carbon emissions over the next decade commensurate with responding to the climate emergency. To that end, readily available and proven direct wind solutions must be integrated at the heart of decarbonisation deliberations, which is currently not the case.

19 July – Article: “Owners drawn to wind-assist technology amid high fuel prices: Wind technology is proving popular as a way of seeing tangible fuel savings and a cut in emissions now while zero-emission fuels are still being developed.”

This Lloyd’s List article focuses on the fact that shipowners are being increasingly drawn to wind propulsion technology amid high fuel prices. This level of engagement signals not just a short term upswing in interest in wind-assist technologies due to current fuel price pressure, but a sustained engagement for numerous shipowners with wind propulsion development and a move towards a basket of resilient solutions that can meet the decarbonisation challenge we are facing in this decade. Wind propulsion systems are fully compatible with whatever alternative fuels choices are made in the coming decades and hold the potential to shift the shipping industry into a pioneering decarbonisation position, with this free energy source actually covering those costs through fuel savings as we move forward.

27 June – 01 July UN Ocean Conference

28 June: Side Event – Joining the dots between sustainable maritime logistics and planetary boundaries

We had a very frank and productive panel discussion at the UN Ocean Conference on the climate and ocean impacts of shipping and the solutions and pathways that we have available to engineer the change that we need to see in the industry. True costs of fuel and infrastructure, higher ambition, collaboration, protection and incentivisation of first movers, early adopters, just transition and so on.

The side event was attended by the RH, crown princess Victoria of Sweden, Ministers from Finland and Sweden, and other Distinguished Guests and contributors, we came to the conclusion that:

* The industry agrees that we need to act now

* Multiple enablers need to be put in place in combination

* Everybody needs to contribute with his/her share

* Put a price on carbon emission

* Establish COALITIONS of the DARING

* Question what, how, and why we ship

* Ensure that predictable regulative frameworks are established

This event was organized by the Governments of Finland and Sweden, Seas at Risk, Ocean Care, Clean Shipping Coalition, Clean Arctic Alliance together with the Technical Research Center of Finland (VTT) and Research Institutes of Sweden (RISE) and IWSA.

24 June: Announcement from Cargill in support of Wind Propulsion

“Cargill could retrofit five to 10 ships for wind but newbuilds are the ‘game-changer’.” Cargill Ocean Transportation president Jan Dieleman, who leads the shipping division of US commodities giant Cargill, pointed to even greater promise in using the technology in new buildings that have been optimised for wind power.

We would certainly agree that while we need to retrofit as many ships as possible to extend the carbon budget and bring down fuel/emissions quickly, when you are able to optimise all of the design aspects of the vessel in relation to maximising the wind potential then really significant gains can be made – a ‘game-changer’ indeed.

13-15 June Blue Week, SS Rotterdam

The annual Natural Propulsion seminar was held onboard the SS Rotterdam and as with past years this was a great opportunity to get insights into new wind propulsion projects and developments. The presentation links are available from:

IWSA also held it’s quarterly members meeting on the Tuesday morning with over 30 members in attendance physically and the same number virtually. This was then followed by a WASP project workshop on finance and then many members broke into project groups or attended the zero-emissions shipping session. IWSA’s participation was capped with a presentation by Gavin Allwright, Secretary General during the joint forum on Wednesday, discussing alignments and collaboration across decarbonisation sectors.


IWSA Secretary: There is need for all zero-emissions energy provision to vessels to be treated equally

The rising tide of renewable energy deployment needs to lift all ships, or more precisely ‘all energy sources’. The high tide of decarbonisation will be a huge challenge for the entire industry, thus it is critical to use every tool we have available, especially those that are deployable immediately, such as wind propulsion systems.

07 June: MEPC78 at International Maritime Organization starts today, sandwiched in between World Environment Day 2022 yesterday with the theme of ‘Only One Earth’ and World Oceans Day, on the 8th June, with the theme of ‘Revitalization: Collective Action for the Ocean’. While these slogans can often be dismissed as platitudes, I think we all need to reflect on the severity and urgency of the situation, as our final window for action to avert 1.5c global heating draws to a close.

We have the tools, skills and knowledge to do the job in shipping, we just need to match that with the level of ambition to eliminate carbon, all climate forcing emissions this decade and for shipping to step forward as a climate pioneer. We stand ready, as wind propulsion advocates to play our part in delivering on that ambition.

23 February – Final Call for Submissions for the Natural Propulsion Seminar – BlueWeek 13-16 June

Please find below the final call for contributions/presentation/papers for the Natural Propulsion Seminar, as part of MARIN’s Blueweek on 13-16 June. This is always a key event in the wind propulsion calendar, and an important collaboration with IWSA. MARIN will be hosting and leading the proceedings and IWSA will moderate the Q&A/discussion sessions. On the following day, we will also hold our IWSA members meeting during the event (Tuesday AM, 14 June), so a great opportunity to hear about some interesting projects and also have time together with IWSA members (finally in person).

More information:

For the NPS, there is generally a preference for projects that haven’t before presented, though those with significant milestones reached are very welcome back, if there is space in the line-up.

BlueWeek to be held on board SS Rotterdam
Started in 2012, BlueWeek is an event which merges public seminars with (closed) project meetings relating to the energy transition in shipping and offshore. In the public seminars, the progress on projects is shared. Also, pitches allow new collaborative projects to gather participants (or just feedback). In parallel there’s the opportunity to have your private collaborative project meetings, making for an efficient overall.

The event will be hybrid but to get the most out of it, we encourage attending in person on board

Opportunities to contribute to Natural Propulsion Seminar Program (Monday afternoon, 13th June)
One of the “disciplines” is “Natural Propulsion”. It is mainly for presentations in short slots (c.15 min) and the scope includes all natural sources that can be used for propulsion of ships. This includes waves, solar or any other source. In practice a large part of the program is on wind propulsion. There are no papers, allowing for relatively little preparation time. The focus is on technological developments, design and modelling, although the wider context around that is not forgotten. Since we went online last year, the audience is world wide with a large fraction of the people from Europe and the United States. Attendees and presenters are often from technology suppliers, academia, designers and shipyards and to a lesser extent ship owners/operators and regulators.

Pitches and collaborative projects: Within Blue Week, we also specifically wish to facilitate collaborative projects. The option to present a pitch talk of a few minutes is specifically intended to initiate new collaborative projects. You can present your project ideas and then invite others to give you feedback or directly join the project.

If you want to present, pitch or hold your project meeting at BlueWeek, then please email and

09 February – Wind Propulsion Recommendations for Policy Makers and World Leaders Delivered at the One Ocean Summit

Following the very well received Wind Propulsion Forum at the One Ocean Summit this morning, the International Windship Association Secretary General, Gavin Allwright delivered a number of recommendations and a call for action for policy makers and world leaders attending the summit. The key parts from that statement are as follows:

“During the forum, we have already heard calls for an appropriate level of carbon pricing and levies to be brought into the shipping industry, these are very clear, so I won’t take time repeating those now.

Critically, we need to fully integrate the potential of wind-powered ships within International and European institutions, in order to further improve ocean protection and urgently deliver on decarbonisation pledges by adopting an ‘propulsion- or energy-centric approach rather than a narrow fuel-centric one’.

To this end, actively supporting the evolution of the International Maritime Organization’s texts so that wind propulsion is considered in the same way as alternative fuels and is brought to the heart of the maritime transport decarbonisation pathway. Also, promoting direct wind power for shipping in European policies dedicated to the greening of the fleet, including in the proposals currently under discussion such as Fuel EU Maritime and the wider ‘Fit 55’ program.

Another key recommendation is a concrete one, to deploy a fleet of wind-propelled vessels in island territories that are extremely vulnerable to climate change and that will be confronted with the challenges of availability and cost of alternative fuels – in particular the Pacific islands, but also the Caribbean territories and many other least developed regions and small island developing states. This fleet will stand as a strong contributing factor in building resilience in these regions and will be a symbol of international solidarity and a commitment to a ‘Just Transition’ in the Ocean sphere.

Your support nationally, regionally and internationally for the research, development and deployment of direct wind propulsion systems and vessels will be a clear, unequivocal message that urgent and deep reductions in shipping emissions are not just possible this decade, but affordable and hugely beneficial to the blue economy and ocean environment.

02 February – WIND FOR THE FUTURE FORUM at the One Ocean Summit – Wind propulsion to be front and centre at the ONE OCEAN SUMMIT

The ocean covers more than 70% of the surface of our planet, yet too often remains on the side lines of major European and international events. 
The ocean is a regulator of major environmental balances, and climate in particular, a provider of resources, an important enabler of trade, and an essential link between countries and human communities. However, it is now seriously threatened by numerous pressures, such as the effects of climate change, pollution or the overexploitation of marine resources. 
In an effort to mobilise the international community and take tangible action to mitigate such pressures on the ocean, the President of the French Republic has decided to organise a One Planet Summit dedicated to the ocean, scheduled to take place in Brest on 9-11 February 2022. The “One Ocean Summit” will be held in the context of the French Presidency of the Council of the European Union, with the support of the United Nations. 

The International Windship Association and Association Wind Ship are thrilled to announce the organisation of a forum dedicated to wind propulsion at the opening of this summit.
Two panels and a debate will feed the reflections on the role of wind propulsion into the pathway for decarbonising shipping. This forum highlights the serious consideration that wind propulsion is receiving as an alternative energy source for shipping. The discussion will focus on the means to accelerate the deployment of these solutions, which carry such societal and environmental promise.  Register Here

30 November 2021 – Research: Tack to the future: how feasible is weather routing for wind-assisted ships?
A new fellowship conducted by Dr James Mason at the Tyndall Centre for Climate Change Research will investigate the real-time feasibility of combining wind propulsion with weather routing to cut carbon in international shipping. Building on previous Tyndall Centre research that highlights how weather routing can amplify savings from Flettner rotors by over 1.5 times, the new fellowship aims to understand how well savings translate when used in a real-time operational environment.

The Tyndall Centre are looking for stakeholders to participate in the project to identify barriers and challenges that prevent sail manufacturers, operators, ship owners and others from adopting this measure. While participation will involve discussions and interviews, participants will also have direct access to the researchers focusing on the decarbonisation agenda within the Tyndall Centre, alongside early sight of the results. Over the last decade, the team at Tyndall Manchester have published world-leading research on low-carbon shipping and have been a key influence in driving the decarbonisation agenda. Any level of participation is welcomed.

To express your interest in this opportunity, email Dr James Mason at

16 August – Farewell to Wind Propulsion Visionary, Mr. Aloys Wobben, founder of Enercon and father of the E-ship 1
Very sad to hear about the passing of Mr. Aloys Wobben, 69, after a long illness. His vision for a new build wind-hybrid cargo vessel with four Enercon-designed Flettner rotors was launched in 2010 and has been in operation since saving c.20% of fuel. His vision was encapsulated in the choice of name, E-ship 1, the first of a fleet of vessels that unfortunately wasn’t replicated at the time, but which helped inspire a new industry and all of us at IWSA. We hope that we will be able to deliver on a wind powered fleet during this decade of wind propulsion, and that will form a small part of Mr Wobben’s legacy. Our condolences to the Wobben family and to the Enercon team and E-ship 1 crew.

08 August: Short Youtube film: Is Wind Power the Future of Freight Shipping? from Just Have a Think

The film covers some of the key aspects of wind propulsion and three of the seven technology groups that are being developed today. As the film makers state: “Wind power for boats has mostly been confined to niche sports and leisure activities these days, but new technologies are bringing a fresh perspective to the role that the wind can play in reducing costs and greenhouse gas emissions in the global freight shipping industry. That industry currently accounts for nearly 3% of all GHG emissions, so freight operators are on a quest to reach net zero by 2050. Here’s three of the most promising wind power options that could help them get there.”

04 August – Article: Wind assisted ship propulsion has returned in ship design – Learn a little more about the E-ship 1, in this interview with the Ship’s master Antje-Friederike Herbst, one of very few female captains in the German merchant fleet. 

Since commissioning, E-Ship 1 has travelled over 500,000 nm with the rotors reducing annual fuel consumption by 20% (annual mean) compared to similar-size conventionally powered vessels (920t of MGO at 13kn). This prototype vessel wasn’t replicated for a number of reasons (none of which were related to performance), and won the IWSA 2016 award Wind Propulsion in Commercial Shipping – Innovation Award. E-ship 1 continues to ply the waves, but now she is joined by nine other rotor installed vessels from tankers to bulkers, ferries to general cargo and many more in the pipeline.  Read more…

03 August – Webinar scheduled for 08 September, “Going beyond Compliance: Harnessing the wind to meet IMO’s EEXI regulations and increasing demand for higher ESG standards”. IWSA SG will be on the panel along with Tuomas Riski, Norsepower CEO,  Kris Fumberger, Sustainability Manager RightShip, Aude Leblanc Technology Leader, sustainable shipping Bureau Veritas & moderated by Alisdair Pettigrew, Director of BLUE Communications

The panel will explore potential market consolidation during the transition to net zero and the commercial and regulatory drivers impacting decision making for developing resilient fleets. With this combination of factors, shipping faces an unprecedented challenge to decarbonise that will require the sector to invest in new initiatives driven by push and pull effects. What are the near-term challenges for ship owners and operators in meeting imminent EEXI and CII requirements and how can these be overcome? How can ship owner and charterers collaborate better to reach favourable commercial agreements whilst working towards environmental goals? How can the industry future-proof against ESG demands and higher fuel costs?

05 May – Leaders Magazine Interview  – IWSA SG Gavin Allwright was recently interviewed by Dr Magdy Sadek, editor of for the Saudi Arabian magazine ‘Leaders’, and was was asked to reflect on the place that wind propulsion can have for stakeholders in the region and specifically in relation to the KSA Vision 2030. There is great potential benefit for Saudi fleet operators and owners, even with a fleet that is relatively new and best in class when it comes to efficiency and regulatory compliance. The deployment of wind propulsion systems can go even further and make those vessels leading statements of a ‘beyond compliance’ approach, locking in lower fuel costs and emissions and helping to take a leading role in the decarbonisation of shipping. There is nothing more visual as a statement of the intent to decarbonise a vessel or a fleet than wind-assist installations and as a zero-emissions energy source with modern wind propulsion technologies increasingly available to harness that, wind propulsion will certainly be a leading technology in the decarbonisation toolbox going forward.

24 March – Open Letter Release – A Level Playing Field Needed in Shipping Decarbonisation 

Over 90 maritime corporations, shipowners, designers and technology providers all involved with wind propulsion have come together to release this open letter, calling for all maritime industry decision-makers and the entire shipping community to fully assess and utilise all available power solutions that deliver the necessary deep, swift cuts in carbon emissions over the next decade commensurate with responding to the climate emergency. To that end, readily available and proven wind propulsion solutions must be integrated at the very heart of decarbonisation deliberations, which is currently not the case.

This is a critical time for all political, financial and corporate leaders to take decarbonisation seriously and the letter calls for establishing a multi-stakeholder International Working Group to evaluate and quantify wind propulsion’s potential, to launch a comprehensive Strategic Review of shipping industry decarbonisation efforts in the context of the climate emergency. It asks to ensure a ‘level playing field’ is created and maintained for all power systems and to do more and go beyond the current narrow fuel-centric approach.
