How we calculate savings
Our in-house Fuel Saving Assessment
Anemoi estimate the expected fuel and emissions savings using our in-house Fuel Saving Assessment Method (FSAM). This method combines the following 4 key sets of input data:
- Rotor performance data, from our UK test facility
- Vessel performance data, from the Client or Clarksons Research World Fleet Register
- Route data, from the Client or 3rd Party AIS provider
- Wind Data, from NASA dataset
These 4 sets of data are run within FSAM to determine the expected fuel and emissions savings for the vessel on any desired trade routes. Thousands of historic voyages on each route are simulated for the previous 5 years to ensure that the results reflect the wind conditions experienced. We present “net” savings, which take into account the negative impacts of Rotor Sail operation including headwind drag and increased generator usage to give a fair and transparent estimation of performance.

Fuel Saving Assessment
See how much you could save
The first step in understanding the potential of Anemoi Rotor Sails for your vessel is for us to undertake a fuel and emission saving assessment. By sending us some specific information about your vessel(s), we can provide a bespoke Rotor Sail arrangement and estimate of your potential savings.
