Hybrid vessel drive concepts connect mechanic and electric propulsion in the main drive lines of the vessel. The diesel motor of the vessel is supported by highly efficient and flexible electric machines in order to generate maximum efficiency and durability of the drive line. Depending on operation and performance requirements, the electric machine (PTI) clutched to the diesel motor generates additional thrusts of the propulsion propeller or the generator operation (PTO) and provides the board components with electric energy. Both operation modes generate lower CO2 emissions of the vessel and can be realized with engines by ELIN Motors.

Electric Motors In Hybrid Propulsion Systems

Currently, mostly low-voltage asynchronous machines with cage rotors are employed in PTO-PTI-Hybrid Systems. However, a few drives are realized with PM synchronous machines (Direct Drives).

  • Performance range: 150 – 8.000 kW
  • Voltage range: 400 – 11.000 V
