Wärtsilä EnergoPac
Integrated propeller and rudder design for coastal and seagoing vessels that reduces flow separation behind the propeller hub and rudder resistance, with proven 2–9% power savings at trial speed.
Description
Wärtsilä EnergoPac is an optimised propulsion and manoeuvring solution that integrates the design of the propeller and rudder to reduce fuel consumption and CO2 emissions. Each system is tailored to the vessel, optimising energy efficiency without compromising manoeuvrability or comfort. It was developed in co-operation with rudder specialist Becker Marine Systems.
How it works
- Reduces flow separation behind the propeller hub
- High-lift rudder performance requires smaller steering angles, reducing rudder resistance during course keeping
- Creates less drag than conventional rudder systems for the same course-keeping capability
Key benefits
- Proven power savings of 2–9% at trial speed, depending on vessel type, operating profile and reference propeller and rudder
- Excellent manoeuvrability
- Significant reduction of propeller-induced pressure pulses on the hull, lowering vibration
Applications
Coastal and ocean-going vessels with a significant share of free sailing time, particularly vessels with large propeller hubs and highly loaded controllable pitch propellers: RoRo vessels, ferries, container and multipurpose vessels, and ice-class vessels. Also applicable with fixed pitch propellers.

OMEGA Reinforced Laser Plate Banks for Cargo Hold Heating
Structurally reinforced stainless laser-plate heat-exchanger banks that replace failing pipe coils in barge and tanker cargo holds — built to survive sloshing loads in part-filled tanks while heating crude oil, caustic soda and other cargoes.
Equipment
Fluidic Air Lubrication
Alfa Laval fluidic air lubrication (OceanGlide) reduces hull friction with an even air layer over the flat bottom, generated by fluidic oscillators with few compressors, cutting propulsion power and fuel use.
