See moreThe Joint Research Project mission is to collect and develop, through collaboration, a full set of ship performance data, to better understand the potential for ship energy efficiency.
Model tests results, Computational Fluid Dynamic (CFD) calculations, sea trials measurements and long-term monitoring data.
Recommendations and best practices on ship scale CFD.
Confidence in CFD to make more accurate energy-efficiency predictions.
