World’s 1st Ferry Fitted With Wind-Powered Rotor Sail

Yangzhou Xintianhe Rope Co.,Ltd | Updated: Apr 11, 2018

Viking Line’s passenger ship M/S Viking Grace has been fitted with a rotor sail for the utilization of wind power, becoming the world’s first passenger ship to feature the technology.

The Rotor Sail Solution, developed by the Finnish company Norsepower Oy, will cut fuel consumption and reduce emissions by up to 900 tonnes annually, Viking Line said.

The LNG-fueled Viking Grace will be deployed on wind-assisted voyages between Turku, Finland and Stockholm, Sweden from April 12, 2018.

“As the rotor is spinning, the passing air will flow with a lower pressure on one side then the opposite side. The propulsion force created by this pressure difference will drive the vessel forward. The rotor sail operation is automated and the system will shut down in response to any disadvantageous changes in the direction or force of the wind,” the company explained.
