Fuel savings and a reduction in emissions can be achieved with Wärtsilä Energopac. This is an integrated propulsion and steering system which increases the propulsion efficiency, but does not compromise on manoeuvring characteristics and comfort levels. Energopac includes a special propeller design, a sophisticated high-lift flap rudder equipped with an efficiency bulb and a special fairing cap connected to the propeller hub. The bulb and fairingcap work together to streamline the water flow behind the propeller while the twisted leading edge and rudderflap reduce rudder drag. Depending on the 11 specific application, the power savings and emissions control with Wärtsilä Energopac may result in operational savings of up to 9%.
