Roro Ship To Be Fitted With Tilting Rotor Sails

A Ro-Ro cargo ship operating in the North Sea will be fitted with two of Norsepower’s largest Rotor Sails, reducing the vessel's total emissions by as much as 25%. 

The Rotor Sail is essentially a modernized version of the Flettner rotor, a rotating cylinder that uses the Magnus effect to harness wind power to thrust a ship, taking some of the load off of the ship's main engines and therefore reducing fuel usage and emissions.

At 35 meters tall and five meters wide, the Rotor Sails slated for retrofit on board Norwegian shipping company Sea-Cargo's SC Connector will be the largest ever built by Finnish company Norsepower.

They'll also be the first to have a tilting function. The 12,251 gross tonne sidedoor Ro-Ro vessel operates on routes that require the ship to navigate under multiple bridges and powerlines, so Norsepower and Sea-Cargo jointly developed the Rotor Sails to be tiltable. When required, they can be raised and lowered to almost horizontal while underway, which will also be helpful when encountering extreme conditions in the North Sea.

“By fitting rotor sails to SC Connector, we are utilizing available renewable energy. The wind forces are used directly for propulsion, without the transformation losses associated with other energy carriers. As a sailing hybrid, we expect to reduce the fuel consumption and ....
