Norsepower auxiliary ship wind propulsion

The Norsepower Rotor Sail, a spinning cylinder that to harness wind power to propel a ship.

The Norsepower Rotor Sail Solutionis a modernized version of the Flettner rotor, that uses the Magnus effect to harvest wind to power ships.

Rotor sails can be used with new vessels or they can be retrofitted to existing ships.

Fuel costs can be reduced typically by 5% to 20% without lowering the operating speed of the vessel.

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.

The Norsepower Rotor Sail Solution was installed in November 2014 on board Bore’s Estraden. Based on the independently verified results, the technology has potential for fuel savings of up to 20% for vessels with multiple, large rotors traveling in areas with favourable wind conditions.

According to the company, they are suitable for installation on ships, which have the required installation space available space on deck. Typically such vessels are Ro-Ro ships, tankers, bulk carriers and cruise passenger vessels.
