Wärtsilä's retrofit package for the Corsica Linea ferry 'Pascal Paoli' has resulted in fuel savings of up to 22 percent. This significant gain in energy efficiency on each trip has been made possible by the installation of a new twin screw controllable pitch propeller (CPP) system with blades optimised for the ship's operating profile, the Wärtsilä EnergoProFin energy saving propeller cap, a controls retrofit, and combinator curves for the ship's various operating modes.
