The uptake of wind propulsion as a solution to reduce fuel consumption and greenhouse gas emissions is accelerating.

Compared to future alternative fuel solutions, the technology can be applied now and the required ‘fuel’ - wind - is freely available. The challenge with wind propulsion is that the obtained savings are strongly dependent on the operation of the vessel.

When predicting the savings from wind propulsion to comply with energy efficiency regulations, such as for the EEDI, only one combination of speed and loading condition is considered. In
reality the vessel will operate at various conditions, often at a lower ship speed and reduced draught.

At higher wind speeds the losses increase and savings start to decrease
