This innovation makes it possible to keep the speed in the optimum power range at all times and only provide the engine power that is actually required. By coupling several torque drives in one shaft line, redundancy can be achieved even on an inland waterway vessel or tugboat with only one propeller, thereby increasing reliability.

In addition, this drive technology reduces propeller slip (cavitation), which is characteristic of conventional ship drives, by almost 100 % even when reversing, thus improving maneuverability.
