World’s First Tiltable Rotor Sails Installed Maritime Activity Reports, Inc. (Photo: Norsepower) Auxiliary wind propulsion systems provide Norsepower said it installed the world’s first tiltable Rotor Sails for SEA-CARGO, a logistics provider in the North Sea market. According the analysis conducted by Norsepower and SEA-CARGO, installation of the two 35-meter tall Rotor Sails on board the SC Connector, a 12,251 gross tonne (GT) sidedoor RoRo vessel, can achieve a fuel consumption, fuel cost and carbon emissions reduction of up to 25%. In good wind conditions, the sailing vessel will maintain regular service speed by sail alone. Norsepower’s Rotor Sail Solution is a modernized version of the Flettner rotor, a spinning cylinder that uses the Magnus effect to harness wind power to thrust a ship, thereby reducing fuel burn and emissions. The solution is fully automated and detects whenever the wind is strong enough to deliver fuel and emission savings, at which point the Rotor Sails start automatically. The newly installed tiltable version is geared toward vessels that must negotiate height restricted routes.
