Rudder for ships
ENERGOPAC
Wärtsilä Corporation
The key objective of the Energopac is to reduce the vessel’s fuel consumption by fully integrating the design of both the propeller and rudder.
Each Energopac is designed to fit the vessel and to meet its specific requirements. This allows
Energopac to be fully optimized for energy efficiency, whilst not compromising either the vessel’s manoeuvrability or its comfort levels.
Fuel savings
Energopac reduces fuel consumption by effectively reducing the flow separation behind the propeller hub. Extended studies show that for the same course-keeping capabilities, Energopac will create less drag than conventional rudder systems. Most notably, when using small – corrective – steering forces to maintain course, the difference in rudder resistance is significant. The high-lift performance of Energopac requires smaller steering angles, which consequently reduces rudder resistance.
