The coming two years could become the key period when wind assist technologies come of age, again.
As climate scientists and political minds continue their chess game around the UNFCCC meetings, technology firms that seek to fuel shipping by another means than from fossilised hydrocarbons are finding they have an societal ear into which they can shout. And in shipping, that corner of society ignored by the Paris Agreement, and now facing the prospect of an IMO devised regulatory roadmap, there are some technological ideas that are getting onboard ships and which environmental groups and the technology firms alike, hope will open a new age for shipping.
It’s hard not to use cliched metaphors when writing about wind-assist technologies in shipping; the wind is in their sails and it will be smooth sailing form here, but there have been a few announcements in recent weeks relating to technologies and systems, or plans for new ships, that give a hint of the future to come.
As people working in the shipping industry assess their future investments, and which direction the industry will take, it does so knowing that there is now a commitment by the IMO to put flesh on a regulatory road map that will push the industry as a whole cut its emissions to 50% of what they were in 2008 by 2050. This comes regardless of any growth in the industry given how shipping is directly linked to global trade (the better the economy the likelihood the need for more ships). New technologies, but also old technologies rethought, are going to be part of the answer, and utilising windpower as a renewable energy source is clearly in this mix.
The wind assist technologies have certainly matured in recent years, and the formation of the International Windship Association was a step in the right direction after a few years of technology start-ups spending far too much energy bickering with each other about which technology works and which does not, rather than pushing a message to the shipowning community that they had solutions that could be a key part of the future industry landscape.
So here’s some recent announcements that show that wind assist is part of the future. And one should note, not only the technology companies that are developing the cleantech solutions for shipping (And who are fighting to get the backing to make viable solutions to help meet shipowners’ soon to be regulated targets), but those forward thinking shipowners that are already allowing these systems to be trialed and used on their ships to enable vital real-world experience.
It is shipping companies such as these that need to be recognised for offering a platform: Viking Line (Norsepower flettner), Bore – A Spliettof Group Company (Norsepower flettner), Maersk Tankers (Norsepower Flettner) Ultrabulk (Smart Shipping Alliance Smart Rig) Airbus (Air Sea Kite) Blue Planet Shipping (Anemoi flettner). China Merchant Energy (Dalian Shipbuilding rigitd sail) Renault Group (Neoline sail) and likely some more that will be added here.
The Anemoi system is a flettner rotor system, similar to that of Norsepower, however in the company’s recently published videos one can see that a key part of this technolgy is the sliding platforms that help move the flettners up and down the side of the deck as needed (i.e. to give shore and shipboard cranes access and during heavy weather). The trial installation is on MV Afros, operated by Blue Planet Shipping in Greece. If you are wondering about the company name, Anemoi is the Greek god of the winds.
Finnish cleantech firm Norsepower has become something of a posterboy for the nascent wind assist industry through some well aimed PR work. The company has so far managed to get its systems retrofitted onto three vessels, the third one being a Maersk tanker this summer, and has an order for a pair of flettners to go not a cruise ferry newbuilding. Being a European company it has been successful due in part to its ability to tap into the European drive for clean transport solutions by securing EU grant money
This EU funded project led to a large flettner rotor being installed on Fehn Pollux, a coastal vessel operated by Leer-based Fehn Ship Management. The flettner, fastened on the vessel’s forward part has performed well accroding to project scientist Professor Michael Vahs, who has been researching wind propulsion for seagoing vessels at Emden / Leer University for more than 15 years. “In optimal conditions, this prototype will deliver more thrust than the main engine,” he has been quoted as saying. The flettner was retrofitted onto Fehn Pollux this year.
The Chinese Shipbuilder has undertaken the most noticeable of recent trials, on a VLCC. The company put a rigid sail system through five days of trials on New Veracity, a 300,000 dwt tanker owned by China Merchant Energy Shipping. The trial were between October 20th and October 24th 2018. The sea trials were mainly of the systems wind sail alarm points and control systems as well as a demonstration test. it was also used for EEDI evaluation.
Econowind has been able to install a trial rigid sail onboard a coastal vessel owned and operated by Dutch short sea shipping operater Wijnne Barents.

Coming soon: Recent project announcements that may result in more real-life examples
Smart Green Shipping Alliance
ON November 20th the power generation firm, Drax, announced it would be part of feasibility study to put a stiff sail onto a bulk carrier operated by Danish owner Ultrabulk. The trials are being run with Diane Gilpin’s Smart Green Shipping Alliance and could eventually see a system known as a Fastrig installed on a selected bulk vessel ailing across the North Atlantic transporting biomass to a Drax power station in North England. The trial has UK state backing through InnovateUK with a feasibility study potentially leading to a commercial demonstration in 2021.
Neoline is a French start-up company, in the Nantes region set to construct a vessel in the coming year, backed by the Renault Group. The intention is to have the vessel in service by 2020, running across the Atlantic
Another French company AirSeas, which has formed out of Airbus, is to install a kite system on one of Airbus’s vessels used to deliver airplane fuselage parts. The system is highly reminiscent of that seen a few years ago by Skysails from Germany. Skysails had a prototype installed on a vessel (Beluga Skysails) but the company hit financial problems. The AirSeas Kite “SeaWing” comes with the as expected claims of fuel savings to be found with many of these wind assist prototypes.
There are other projects that have seen developments in plans for feasibility studies or small sale trials (not on commercial tonnage. These include Bound4Blue, which could have a system installed in 2019, Wind+Wing, Windship Technology, Blue Technology, Ponant, Ecomarine and UT Wind Challenger (MOL)
There are other technology companies in this market. Companies like Magnuss, Oceanfoil, Propelwind, Skysails, Ecoliner and even the Ecoship Peaceboat (Peaceboat announed it has placed an order with the Helsinki Shipyard Arctech overa year ago, but has yet to formally announce when building will start as it seeks to finalise its funding position) , These companies are likely in need of more finaicla support, and of course shipping companies with which to build feasibility studies and test programmes. They all claim to have done their homework, saying their ideas or systems work. In the case of Skysails, the company has already been commercially selling systems before the tough market condition hit.
There are reports of other projects at the moment, but they remain under embargo.
The International Wind Ship Association
ISWA was formed by the industry, with membership including the companies developing the solutions as well as those helping get the systems on board test vessels to help prove viability. The association has now grown to a point where it is developing plans for regional hubs to assist what it sees as the growing market interest in wind assist technology.
And to end the cliche’s here’s the last verse of that Bob Dylan song:
Yes, ‘n’ how many times must a man look up
Before he can see the sky?
Yes, ‘n’ how many ears must one man have
Before he can hear people cry?
Yes, ‘n’ how many deaths will it take till he knows
That too many people have died?
The answer, my friend, is blowin’ in the wind
The answer is blowin’ in the wind
