The Finnish engineering company Norsepower has begun sea trials of an auxiliary wind propulsion system that it estimates can save 20% on fuel costs. Testing on the 18-metre Rotor Sail Solution has begun on Bore’s M/V Estraden, a commercial cargo vessel, having been installed on the pilot vessel in a 7-hour harbour stay.
In a statement earlier this week, Tuomas Riski, CEO and partner of Norsepower said: “The Norsepower Rotor Sail Solution, which is appropriate for retrofitting to over 20, 000 vessels in the global merchant fleet, can be installed on any vessel without any off-hire costs. In favorable wind conditions our solution is able to produce up to 20% savings in fuel costs with a payback period of less than four years. The target of the pilot project, which has now started, is to prove the savings potential and usability aspects of our technology."
The Norsepower Rotor Sail Solution is a modernized version of the Flettner rotor. This auxiliary wind propulsion system helps cargo vessels significantly reduce fuel consumption. When the wind conditions are favorable, 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.
