The Norsepower Rotor Sail Solution is a modernized version of the Flettner rotor – a spinning cylinder that uses the Magnus effect to harness wind power to propel a ship. When the wind conditions are favourable, Norsepower Rotor Sails allow the main engines to be throttled back, saving fuel and reducing emissions while providing the power needed to maintain speed and voyage time. Rotor sails can be used with new vessels or they can be retrofitted to existing ships.

Norsepower's first delivery project with two 18-metre Rotor Sails has been completed on board Bore's 9,700 DWT Ro-Ro carrier MS Estraden. Based on the successful sea trials, the technology has potential for fuel savings of up to 20% for vessels with multiple, large rotors traveling on favourable wind routes.

The proposed paper presents the newest delivery projects of the Norsepower Rotor Sail Solution, including Rotor Sail layouts and simulation results of the savings potential of the new projects.
