Ferry-based wind power generates energy, cuts resistance

International ferry operator Stena Line has launched a unique project it says is the first of its kind in the world: a passenger ferry equipped with two wind turbines.

The turbines at the prow of the Stena Jutlandica, Gothenburg-Fredrikshaven, are aimed at both supplying energy and reducing fuel consumption.

“Within our Energy Saving Programme, we are currently pursuing 200 environment improvement projects and this is yet another very interesting project,” said Robert Åkerlund, director technical & HR at Stena Line.

The ferry-based wind turbines will be mounted on four-meter-high masts on the prow of the ship. The turbines will produce current for the ship’s electricity grid. From their location on the prow, they will also contribute to a reduction in the air resistance.

“The two turbines will generate about 23,000 kilowatt-hours per year, equivalent to the domestic electricity consumption for four normal homes during one year,” Åkerlund said. “Among other things, the electricity will be used to power the lighting on the Jutlandica’s car deck.”

The reduced air resistance at sea will result in a reduction in fuel consumption of between 80 and 90 tons per year.
