Wärtsilä introduced the FPP Opti Design, a new fixed pitch propeller (FPP) design concept. According to Wärtsilä, the new design offers fuel savings of up to 4 percent and highly reliable full scale performance predictions.
The Wärtsilä FPP Opti Design was developed at the company’s Technology and Service Center in the Netherlands. CFD calculations analyze not only the propeller performance but most importantly also, the interaction between the propeller and hull. This provides accurate information to achieve design and parametric optimization.
