Abstract: An electric drive-train for a ship includes a first generator having a rotatable shaft structured to be driven by a first prime mover and an output providing a voltage; a second generator having a rotatable shaft structured to be driven by a second prime mover and an output providing a voltage; an electric machine including a rotatable shaft structured to drive a propeller; a first power electronic converter electrically interconnected with the output of the first generator and structured to power the electric machine; and a second power electronic converter electrically interconnected with the output of the second generator and structured to power the electric machine. A support structure replaces a reduction gear box and supports the first generator, the second generator, the electric machine, the first power electronic converter, and the second power electronic converter.
