Rudder-propeller energy saving package by DMC and MMG for seagoing FPP vessels, with asymmetric leading edge, Costa bulb and adapted hub cap; up to 8% fuel savings.
Description
The ESPAC (Energy Saving Package) Rudder is a combined propeller-rudder package developed by Damen Marine Components with propeller maker Mecklenburger Metallguss (MMG). It pairs an optimised fixed pitch propeller with a slipstream-adapted asymmetric leading edge rudder, a propulsion (Costa) bulb and adapted hub caps.
Key features
- Up to 8% fuel savings
- Costa bulb prevents hub vortex losses and cavitation
- Reduced cavitation, vibration and noise

Applications
