ETI to launch new project to develop flettner rotor sails for ships which could improve fuel efficiency by at least 10%

This is a project to design, develop and fit flettner rotor blades – effectively mechanical sails – which will then be demonstrated and tested at sea in real life conditions. Studies have shown that flettner blades could be beneficial in certain sea conditions around the world reducing fuel consumption in ships of between 7 and 15%. However, there has been insufficient full scale demonstration on a suitable marine vessel to prove the technology benefits. Successfully demonstrating this would make the technology more attractive to shipping companies and investors. The technology, if proved successful, could also be retrofitted to existing shipping fleets and play a significant role in reducing the fuel costs, so improving environmental impact.
