Norsepower Performance Simulator


Find out the potential for a ship’s fuel savings and CO2 emission reduction with Rotor Sails. We’ve prepared an easy to use simulator for your convenience.

All you need to do is to select a Rotor Sail model, route, ship speed and the time-at-sea ratio (annual sailing hours divided by 8765 h) as a percentage, and our simulator will know the answer.   The simulator has been verified to represent the full scale measurement results. The results are calculated for one Rotor Sail unit. You can multiply the results with the number of Rotor Sails to estimate the results for different configurations.   If you would like us to prepare a more detailed simulation case study for your ship or fleet, please contact us at
