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.”

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.

  • Is there enough infrastructure in ports worldwide to facilitate new fuels?
  • Will we have new trades, requiring new ship types – e.g. hydrogen carriers and ammonia product tankers?
  • Agenda for action – next steps. What can we do now to help accelerate the availability of zero-carbon ships while at the same time reducing shipping’s footprint: slow steaming, retrofits, ESG reporting, and verification?

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.
