Norsepower Oy and Bore say the sea trial of Norsepower’s Rotor Sail — a new wind propulsion technology for ships — verified by NAPA and supported by VTT Technical Research Centre of Finland, confirm fuel savings of 2.6 percent using a single small Rotor Sail on a route in the North Sea. With these fuel savings, the technology has a payback period of 4 years, the companies say.

 

Based on the trials, Norsepower and Bore believe that a full system on Estraden with two rotors has the potential to deliver 5 percent efficiency savings on an ongoing basis. Norsepower forecasts savings of 20 percent for vessels with multiple, large rotors traveling in favorable wind routes.
