BAR Technologies has received approval from Lloyd’s Register for its P-Wind methodology – the system it uses to calculate how much power its wind propulsion system, WindWings, can generate on ships.
The model uses advanced computer simulations to measure how air moves around the large wing sails and how much extra thrust they provide.
This allows BAR to accurately predict the fuel savings from each installation.
Lloyd’s Register confirmed the model meets international standards set by the IMO and the International Towing Tank Conference (ITTC).
Shipowners can now include verified WindWings performance data in their Energy Efficiency Design Index (EEDI) and Energy Efficiency Existing Ship Index (EEXI) submissions without lengthy sea trials.
BAR says each WindWing can save about 1.5 tonnes of fuel per day, offering shipowners a reliable and class-approved way to cut fuel use and emissions.
