Wärtsilä's EnergoProFin can create fuel savings of up to 5%

Wärtsilä EnergoProFin is now available for both controllable pitch propellers (CPP) as well as fixed pitch propellers (FPP).

The EnergoProFin is a state-of-the-art energy saving solution that increases propeller efficiency and creates fuel savings of up to 5%.

"Energy efficiency solutions in general are a sound investment, as their impact on both operating costs and environmental compliance is a lasting one," said Tamara de Gruyter, Vice President, Propulsion System Services, Wärtsilä Services.

"We want to help ship operators optimise their existing assets, and that is exactly what Wärtsilä EnergoProFin does, now for controlled pitch propellers as well."

Offering the solution for technologically more challenging CPPs was previously considered impossible, but the Wärtsilä hydrodynamics team managed to find a solution.

The Wärtsilä EnergoProFin is a specially designed propeller cap with hydrofoil section fins on the downstream side of the propeller. It can significantly reduce a vessel's fuel consumption as well as its emission levels.

Propeller caps with fins have existed for three decades, but their application has so far been primarily on FPPs.

Wärtsilä's development work was a spin-off of an EU-funded collaborative project between Wärtsilä and nine other companies.

The Wärtsilä EnergoProFin, which rotates with the propeller, is optimised for propulsion upgrades of existing vessels and as such can be easily mounted without the need for complex structural changes.

One of the most recent EnergoProFin customers is Grandi Navi Veloci S.p.A. (GNV), which operates 10 international routes to and from Spain, France, Albania, Tunisia, Morocco and Malta and five national lines within Italy.
