Rotor Sails is an auxiliary wind propulsion system that reduces the fuel consumption of commercial shipping vessels.
The solution is based on the Magnus effect where a rotating cylinder creates a lift force when it encounters airflow created by the wind. This lift force is due to a pressure difference on different sides of the cylinder. The lift force induced by the Magnus effect can be as much as ten times higher than what the conventional sail could provide, making the principle ideal for auxiliary propulsion on large scale commercial vessels. With Rotor Sails it is possible to reduce the fuel consumption of the ship, saving in fuel costs, but also reducing the emissions related to shipping. Fuel consumption of a ship is typically reduced by 5% to up to 20%. The solution is suitable for approximately 25 000 vessels globally including tankers, passengers vessels, and bulk carriers.
- •Annual average savings potential of around 300-350 kW for one unit of the largest Rotor Sail model.
- •Annual fuel savings of around 300-400 tons.
- •A reduction of annual CO2 emissions of around 900-1200 tons.
- •With an annual economic savings potential in global average wind conditions between 100 000 - 200 000 EUR per Rotor Sail.
- •Typical average fuel savings of around 5-20% per ship.
