Energopac is the optimised propulsion and manoeuvring solution for ocean going vessels Proven fuel saving technology for controllable and fixed pitch propeller applications Advanced hydrodynamic technology is applied to reduce the vessel’s fuel consumption using an integrated propeller and rudder design Outstanding vessel manoeuvrability made possible in co-operation with Hamburg-based Becker Marine Systems, the market leader for high-performance rudders Improved onboard comfort levels compared to conventional propeller and rudder configurations Application EnergoPac can effectively reduce the operational costs for any vessel with a considerable share of free sailing time in its operational profile. It works very well for propellers with a relatively large propeller hub. The potential savings are large for vessels with highly loaded controllable pitch propeller systems, such as RoRo-vessels, ferries, container / multipurpose vessels, and vessels with an ice class notation. In addition to controllable pitch propeller applications, EnergoPac can also be applied on vessels with fixed pitch propellers. Model and actual full scale tests demonstrate a significant reduction in propeller induced pressure pulses on the hull when the EnergoPac system is installed. This makes EnergoPac suitable for vessels where onboard comfort levels are important. Wärtsilä’s high efficiency rudder technology dates back to the 1990s when Wärtsilä started producing energy-saving rudders. This development work was continued in 2007 through co-operation between Wärtsilä’s propulsion specialists and the rudder experts at Becker Marine Systems.
