The reasons for better hydrodynamic efficiency :· The forward propeller rotation energy is utilized in the aft propeller· Propeller loading distribution is easy to select.

By using ABB’s Azipod® propulsion solution, which will use electric power from 8.8MWh batteries and diesel generators, new vessels will reduce fuel consumption by 40 percent. Additionally, the batteries will provide full power for harbor maneuvering and in-port stays and will prepare the vessels for a zero-emission future as more electric shore charging stations become available.
