21 December – Announcement – VALE has just launched a contest for methanol-dual fuel VLOC’s that will feature wind-assist systems and a basket of ship efficiency/green tech. This is a request inviting shipowners to offer bids for contracts of affreightment for a new generation of its 325,000 dwt Guaibamax vessels.

The call comes after over a year of operation for the MV Sea Zhoushan VLOC, installed with five tilting rotors sails supplied by Norsepower. This interest in fleet installation of wind-assist systems is obviously a strong message to the market that wind solutions are a no regret propulsion choice that is compatible with all alternative low carbon fuels and ship efficiency measures. Linking these with voyage optimisation and other operational measures can reap very significant savings before the availability of large volumes of affordable green methanol is on the market. Read more…

20 November: IWSA Asia Tour

IWSA Secretary General returned from a very productive three week trip to Asia with stops in Singapore, South Korea and Japan along with a series of virtual meetings in China. This trip has helped to highlight the growth in interest and activity underway in the region.

Installations – Mitsui O.S.K. Lines, Ltd. has installed the first windchallenger rigs on the Shofu Maru and completed its maiden voyage to Newcastle, Australia and back. A second VLCC, the Aden has recently been launched by Dalian Shipbuilding Heavy Industry Co., Ltd. and China Merchants Energy Shipping in China and “K”​ line (Kawasaki Kisen Kaisha, Ltd) and AIRSEAS are busy with their first kite installation. Dealfeng New Energy Technology rotorsails are preparing for their first installation in the first half of 2023, and we will also soon see units coming off the Yara Marine Technologies and BAR Technologies production line in China.

New Projects – Hand in hand with these, there are quite a few new projects under development. The University of Tokyo has established the MODE project along with numerous industry partners to assess installations, shipbuilders Hyundai Heavy Industries Co., Ltd , Samsung Heavy Industries, DSME CO., LTD, Sumitomo Heavy Industries, Ltd., Jiangnan Shipbuilding (group) Co., Ltd. and Oshima Shipbuilding are all involved with the development of new wind propulsion projects. Marubeni Corporation has also announced a new installation project with bound4blue. ANEMOI has signed a collaboration agreement with COSCO SHIPPING Lines to supply their rotor sails.

Growing Engagement – we are also seeing growing interest across the region from government policy makers, research organisations, naval architect organisations, academia and crucially, shipowners in search of solutions for CII, EEXI and longer term zero-emissions energy options. 

These developments are set to only grow further in the coming months and I look forward to returning to the region next year.

13 November – Wind Propulsion Seminar was held in Tokyo with over 100 attendees from across the shipping world including Japanese policy makers. Our Secretary General joined presenters from ClassNK, MOL, K-lines, Tokyo University and others for a very informative gathering and exciting to hear about all of the current developments and upcoming projects.

08 November – COP27 Address by King Tupou VI of Tonga

We encourage you to listen carefully to the eloquent address given at COP27 by his majesty King Tupou VI of Tonga. As the 3rd most climate change vulnerable country there are many challenges facing the people of these beautiful islands and the King highlights that one critical issue along with securing fresh water is the need for sustainable maritime transport and he calls for the “..use of cutting-edge technologies that promote wind-powered, low carbon emitting modes of transport.”

As an organisation, we stand ready to support these developments and we have already called on EU members to support the building of a fleet of these ships in solidarity with the peoples of the Pacific islands and other SIDs and LDCs. We hope that this important message resonates with the heads of states and industry gathered in Egypt and that ‘delivery’ is indeed at the top of the agenda.

18 October – The European Parliament in Strasbourg are deliberating and votes on the FuelEU Maritime and EUETS. Three points to make:

Zero-emissions: These regulations will set a pathway towards zero-emissions (not just decarbonisation or net-zero), and that is needed before 2050 to align anywhere near of limiting global heating to 1.5C. That pathway needs ambition and the 5-yearly revision process can review that upwards. However, the industry is calling out for higher ambition at the start – give us the goal, the benchmarks and we will deliver. The wind propulsion amendments being tabled to increase the wind reward and identify direct wind power as a significant tool are important steps to help accelerate the scaling of the sector. These will be a key signal to industry and finance that we need to accelerate the process now.

Economy: This is absolutely vital too. Wind propulsion developments have already generated hundreds of jobs in the EU, tens of millions in investment and this is growing daily. A 2016 EU report estimated up to 20,000 jobs would be created installing systems on just 15% of the fleet by 2030. These jobs in shipyards and coastal communities that often struggle to attract direct investment, and would be a multi-billion euro market by the end of the decade. From a shipping industry perspective, the fuel savings alone from wind propulsion by 2050 delivered by a full rollout of wind propulsion across the fleet this decade would not only pay for itself (the only alternative propulsion energy source that can do that), but would also cover the EUR1.4-1.9 trillion required for full decarbonisation of the global fleet.

The Future: We all know that we need to do more. EU decisions will impact our deliberations at IMO level. ‘Fit for 55’ means reducing ghg emissions by 55% by 2030 in the EU, but that needs to be in all sectors and globally – we are far from this today. This goal needs to include all climate forcers and indirect GHG emissions. To reach this higher ambition, wind propulsion needs to be incorporated at the very heart of these efforts – a zero-emissions, benign energy source that is abundant, free and available globally today. If energy is delivered to a wind turbine, then electricity generated and used to create a gas/liquid which is then burned onboard a ship – that is designated a ‘fuel’ and receives well deserved incentives, govt support and scaled financial backing. If that same wind energy propels the ship directly it is designated as a ‘fuel efficiency measure’ and receives far less attention. These artificial, illogical and damaging designations are holding back the drive to zero-emissions, wasting time we can ill afford.

17 October – The White paper ‘Wind Propulsion for Ships‘ focused on wind propulsion developments in France is now available in English  Download here

17-18 October – Wind Propulsion Photo Exhibition – EU Parliament welcomes the wind propulsion photo exhibition. We had a short presentation updating MEPs and staffers on developments in the sector and potential for growth just ahead of the votes on FuelEU Maritime.

13-14 October – OECD – Coastal Shipping Roundtable – IWSA Secretary general attended the International Transport Forum of the OECD discussing coastal shipping and decarbonisation which is a critical sector of shipping worldwide. Wind propulsion will need to be at the heart of the pathway to ensure a viable, resilient and economical transition.

12 October – IWSA joined the STEERER final event and sharing our visions for an optimised and decarbonised maritime network for the future. The work we have been doing in this project will help inform EU maritime policy, innovation and zero-emissions pathways going forward.

08 October – New Video – released covering the delivery of the the first Wind Challenger rig on the bulker Shofu Maru by Mitsui O.S.K. Lines, Ltd.

4 October – Anemoi and COSCO Shipping Heavy Industry to offer full wind propulsion technology installation services – Anemoi Marine Technologies, a UK provider of Rotor Sails to the shipping industry, has reached an agreement with COSCO Shipping Heavy Industry Co (CHI), one of China’s major shipbuilding organisations. CHI has nine yards capable of up to 7.5m dwt annual production across all major vessel segments and a significant global customer base.

29 September – Press release: Wind-powered cargo capacity breaks through 1m dwt mark

Wind propulsion has progressed from a perceived blue sky technology in the previous decade to gaining industry interest in recent years. The conversion of that interest into investment is now happening at a rapid pace, with large commercial vessels featuring wind-assisted propulsion passing the 1m dwt cargo carrying capacity mark.  There are currently 21 large vessels with wind propulsion systems installed onboard and that number will likely grow to 25 (1.2m dwt) by the end of this year.

The passage of wind-powered ship propulsion through this key milestone coincides with the industry’s celebration of World Maritime Day, with the theme “New Technologies for Greener Shipping.” Read more…

02 September – Climate-neutral Sail Cargo Vessel for the Marshall Islands

As part of an international climate protection project with the participation of the Hochschule Emden/Leer, the Deutsche Gesellschaft für Internationale Zusammenarbeit GmbH has commissioned the construction of a new island supplier with sail propulsion for a largely climate-neutral ship operation. The construction contract was concluded with the ship design office Kostec Co. Ltd. and the shipyard SHIPBUILDING ASIA LTD in Korea. The new building, which is around 48 metres long, will have a load capacity of around 290 tdw (tons dead weight) with a measurement of around 460 GT (gross tonnage). In addition to the transport task, the ship will also be used for seafaring training. For this purpose, accommodation for six trainees is planned, who are to be trained in particular for environmentally friendly and climate-friendly ship operation.

The sail area of the three-master will be around 500 square meters. The power supply for the auxiliary operation is also to be provided by renewable energy via photovoltaics, small wind turbines and a shaft generator. A small diesel engine will be used for manoeuvring and driving in unfavorable wind conditions. In the future, a switch to coconut-based biodiesel should be possible.

The further project plan envisages the laying of the keel in March 2023 and the delivery including an intensive testing and training programme for autumn 2023. Read more…

Small island developing states (SIDS) are often at the nexus of the climate, energy, food and water security, logistics and economic crisis that currently blight our world. In these cases, especially those in the Pacific, primary wind powered vessel also find a natural niche at that nexus too:
(i) Climate – these countries contribute virtually no GHGs, but are heavily impacted. Thus having a resilient, independent and low cost heavy lift capability is vital. Direct use of wind power is lowered impact still. (ii) Energy – liquid energy for shipping is hugely expensive as SIDS are often at the ends of supply chains and must pay using hard currency, with purchasing power parity many times higher than developed countries. Not so for abundant, zero cost direct wind power. (iii) Logistics – when shipping is not available, their is no fuel or spare parts need to be flown in then interisland travel grounds to a halt. Wind is a simple and elegant way to keep things moving that can be repaired and maintained locally.
(iv) Economics – Long distances, low population density, low trade volumes, high and volatile energy prices are all a toxic mix for making a resilient regional shipping network. Wind is a key factor for unlocking that conundrum. (v) Food and Water Security – anchored in all of these issues, having ships that aren’t fuel thirsty release funds for development of these basic needs, helps provide a stable trading network enabling farmers and local authorities invest more with the knowledge that value added surplus can be traded are all key to improved security.

Also creates beneficial cycles around opportunity/aspiration, revitalising regional shipyards , jobs, seafarer training and much more. Wind propulsion provides an important element in levelling the playing field.

02 September – Article: How to balance trade-offs when decarbonising the shipping industry
Christiaan De Beukelaer states: “The most promising technological improvement to ships is to harness the wind aboard ships for direct (assistance with) propulsion. Retrofitting existing (and designing new) ships to embrace the millennia-old technology that never required burning fossil fuels should a top priority.”
Looking forward to the book release in January! Read more…

26 August: Article featuring Wind Propulsion: US Global Investors
US Global Investors, investor alert states among other things: “As for shipping, wind propulsion is being touted as the “most impactful emissions reduction technology.” Today, 21 large ocean-going vessels already have wind-assist systems installed, according to the International Windship Association (IWSA), and by the end of 2023, this number could jump to nearly 50. Some of the biggest names in maritime shipping are involved in investing millions of dollars into wind propulsion technology, including Cargill, Maersk and Mitsui. The IWSA calls the 2020s the “Decade of Wind Propulsion.”

We of course agree with this statement, as we agreed with Bloomberg the day before, all building on the Economist and Financial Times articles in January that placed wind propulsion as a ‘surging’ technology sector and ‘one to watch’ for 2022 and beyond.

Abundant, globally available, pure clean zero-emissions energy, delivered free of charge to the point of use without the need for mining, refining, transporting, bunkering or storing – what’s not to like!

* 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

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.      

As we call it, A Win, Win, Wind situation for All!”

The three-day One Ocean summit will run from 09-11 February and was convened by the French President in the context of the French Presidency of the Council of the European Union, with the support from the United Nations.

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

25 January – Article: The Milken Institute quarterly review takes aim at wind propulsion covering a lot of ground (it would take the entire magazine to include every project) and concluding with some conservative comments I have made on a fairly regular basis regarding the economics of harnessing wind that turn the argument that shipping is a hard-to-abate sector when it comes to decarbonisation on it’s head. We are the only transport mode that has the ability to harness an inexhaustable, pure zero-emissions and free energy source directly. That is a low-hanging gift that just keeps giving!  Read more…
