The FPP Opti Design, a new state-of-the-art fixed pitch propeller (FPP) design concept, has been introduced by Wärtsilä. The new design offers fuel savings of up to 4 per cent and highly reliable full scale performance predictions. The concept has been developed utilising the latest computational fluid dynamics (CFD) technology.

The Wärtsilä FPP Opti Design has been developed at the company's Technology and Service Centre in the Netherlands, and is the result of highly experienced design engineers having access to the very latest and most sophisticated software and analysis tools. CFD calculations analyse not only the propeller performance but most importantly also, the interaction between the propeller and hull. This provides extremely accurate information to achieve design and parametric optimisation.
