Displaying items by tag: Aluminium Sail Concept

An interesting take on wind-power made by Econowind has now been installed on DFDS container/side-port loader vessel Lysbris Seaways following recent tests in the Netherlands.

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 (view video) was installed on the deck of Lysbris Seaways last month in Amsterdam. The system is from Dutch company Econowind which created 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.”

Coastal Notes Coastal Notes covers a broad spectrum of stories, events and developments in which some can be quirky and local in nature, while other stories are of national importance and are on-going, but whatever they are about, they need to be told.

Stories can be diverse and they can be influential, albeit some are more subtle than others in nature, while other events can be immediately felt. No more so felt, is firstly to those living along the coastal rim and rural isolated communities. Here the impact poses is increased to those directly linked with the sea, where daily lives are made from earning an income ashore and within coastal waters.

The topics in Coastal Notes can also be about the rare finding of sea-life creatures, a historic shipwreck lost to the passage of time and which has yet many a secret to tell. A trawler's net caught hauling more than fish but cannon balls dating to the Napoleonic era.

Also focusing the attention of Coastal Notes, are the maritime museums which are of national importance to maintaining access and knowledge of historical exhibits for future generations.

Equally to keep an eye on the present day, with activities of existing and planned projects in the pipeline from the wind and wave renewables sector and those of the energy exploration industry.

In addition Coastal Notes has many more angles to cover, be it the weekend boat leisure user taking a sedate cruise off a long straight beach on the coast beach and making a friend with a feathered companion along the way.

In complete contrast is to those who harvest the sea, using small boats based in harbours where infrastructure and safety poses an issue, before they set off to ply their trade at the foot of our highest sea cliffs along the rugged wild western seaboard.

It's all there, as Coastal Notes tells the stories that are arguably as varied to the environment from which they came from and indeed which shape people's interaction with the surrounding environment that is the natural world and our relationship with the sea.
