New Fixed Pitch Propeller Design from Wärtsilä

Thursday, June 05, 2014

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 concept has been developed utilizing 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 analyze 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 optimization.

“Wärtsilä has more than 100 years of experience in developing high quality propeller solutions. To this huge knowledge resource we have now been able to add a highly sophisticated state-of-the-art design approach that is unmatched in the industry. The hull and the propeller, and the interaction between the two, can both now be taken into account during the design process. The result is a higher level of efficiency and lower operating costs,” said Arto Lehtinen, Vice President, Propulsion, Wärtsilä Ship Power.

Energy saving solutions

Wärtsilä said it continues to develop solutions that save energy and improve the efficiency of ship propellers. These include the Tip Rake Concept featuring an extended tip, smoothly curved to the pressure side of the blade with optimized geometrical parameters developed to achieve efficiency improvements, lower pressure pulse levels, and a quieter propeller.

The Wärtsilä EnergoProFin is an innovative propeller cap with fins that rotates together with any make of propeller. By weakening the hub vortex, resistance is decreased and propulsion thrust is increased, resulting in fuel savings of up to 5 percent.

Energopac is Wärtsilä’s optimized propulsion and maneuvering solution that reduces fuel consumption by integrating the propeller and rudder designs. It is fully optimized for energy efficiency without compromising either maneuverability or comfort levels.

The Wärtsilä FPP Opti Design is being highlighted at the Posidonia 2014 exhibition in Athens, Greece.
