DFDS tests aluminium sail concept

An interesting take on wind-power made by Econowind has now been installed on Lysbris Seaways for testing.

 

A metal sail in a box is a novel concept, but it could be a solution to save fuel and emissions for shipping by utilising the power of the wind that nearly all ships once relied on.

The prototype seen in the video above was installed on the deck of Lysbris Seaways on Wednesday 13 November in Amsterdam. What Dutch company Econowind has created is a foldable aluminium sail concept that sits on the deck of a vessel. It comes in a 40-foot container and is a far cry from historic sail designs, as two metallic 10-metre foils, or wings, fold out with the press of a button.

The design and software let the wings move to optimally catch the wind and help propel the vessel forward. Just last week the company received the Dutch Maritime Innovation award for the Econowind unit, which shows promise from earlier testing.

Poul Woodall, Director of Environment, and Vidar Karlsen, Managing Director in Norway, signed the agreement in September for the collaboration with Econowind and Green Shipping Programme (Grønt Skipsfartsprogram or GSP), a Norwegian programme for research into, and development of, green shipping solutions. GSP delivers a theoretical modelling of historic weather data, consumption, routes and more that we use for testing.

Vidar says: “Lysbris Seaways is perfect for testing such a concept. In theory it looks like a good idea, but we need to see if the estimated fuel savings are realistic for this type of vessel. We are going to measure fuel consumption with the sail and get a picture of the efficiency gained over time compared to the regular numbers.”

“The finalised design works automatically, meaning you can open the container from the bridge and open the sail, but for the prototype it’s a bit more hands-on with manual controls and a service engineer present to operate the system. After a successful installation we are now looking forward to seeing the outcome of the two months of testing,” Vidar adds.

Sofie Hebeltoft, Head of CSR, says: “With projects like this we take responsibility for developing new energy sources and methods of propulsion that can take us towards cleaner ships and eventually zero emission shipping. We are therefore extremely grateful for initiatives such as this taken on by Vidar and his team.”
