The dredger is fitted with a double diesel engine that drives the propellers, the generator and the suction pump system. The controllable pitch propellers of the main drive are driven via the two main Siemens/Flender gearboxes directly from the flywheel side of the main engines. The generator for the electrical power supply is also connected via the PTO of the main gearbox with the main machine.

The two suction pump systems are installed on the front side of the engines. In order to generate the maximum suction power, a special Siemens/Flender multi-speed gearbox is located upstream from each of the suction pumps. This special drive configuration ensures optimal loading and discharge process. The pumps can be connected in series for discharging the loading on land.

Two MAN 12V48/60B engines with a power rating of 13.250 kW each are used as the main engines.
