INPROAFE implements an energy generation system via the diesel propulsion motor of a fishing vessel (Shaft-Generator Application).

The project consists of an energy generation system which uses the movement of a permanent magnet motor/generator connected to the diesel propulsion motor of the vessel.

The AC voltage generated by the motor is sent to Siemens S120 series motor modules which convert it into continuous stabilised DC voltage. This grid has 1500kW of power available that can be converted back into AC voltage (using an AFE unit) or used directly by motor modules (for compressors, fishing winches etc.).

The AC voltage generated (up to 700kW) can be used to feed the vessel’s facilities, and can even be used in parallel with the auxiliary diesel generator by adjusting the frequency and voltage for synchronicity.

A liquid-cooled system is used for the Siemens power units (motor modules and AFE).


  • It has a control monitor to show the system variables as well as a registry system which enables easy resolving of any possible system failures.
  • A much smaller generator to feed the vessel’s facilities is needed.
  • It is even possible to work without an auxiliary generator by feeding the entire vessel with the power generated by this system (ISLAND MODE).
  • The system can use the AFE module to feed equipment connected to the DC bus with the propulsion stopped (by feeding from the auxiliary generator).
  • Perfect load synchronicity and distribution with the auxiliary generator (frequency and voltage adjustment), thanks to communication with the vessel’s PMS system.
  • Reduced-size cabinets thanks to the liquid cooling system.
