World's first ferry with wind power


Reduced air resistance will result in a reduction in fuel consumption.



Stena Line has embarked on a project to equip its passenger ferry, the Stena Jutlandica, with two wind turbines, which will contribute by both supplying energy and reducing fuel consumption.

The initiative - said to be the world's first - forms part of Stena Line's environmental strategy. The Stena Jutlandica operates between Frederikshavn, Denmark and Gothenburg, Sweden.

The solution is based on two turbines that will be mounted on 4-metre high masts on the prow of the ship. The two turbines will produce current for the ship's electricity grid. Since they are to be placed on the prow, they will also contribute to a reduction in the air resistance.

"The two turbines will generate about 23,000 kWh per year, equivalent to the domestic electricity consumption for 4 normal homes during one year. Among other things, the electricity will be used to power the lighting on the Jutlandica's car deck," said Robert Akerlund [pictured], Director Technical & HR at Stena Line.

The reduced air resistance at sea will result in a reduction in fuel consumption of between 80 and 90 tonne per year, according to Stena Line. "This can be compared to the consumption of oil for heating 28 homes during one year," Akerlund said.

"Within our Energy Saving Programme, we are currently pursuing 200 environment improvement projects and this is yet another very interesting project. Stena Line has a tradition of leading when it comes to the development of different types of new solutions," commented Akerlund.

Stena Line's operations in Scandinavia are already environmentally certified according to ISO 14001. There are electricity connections for all ships in Gothenburg and, in recent years, a number of environmental improvement measures have been implemented that have resulted in either reduced energy consumption or lower fuel consumption.
