Abstract: A propulsion system for a marine vessel having a first driveline assembly having a first engine and a first motor-generator, a second driveline assembly having a second engine and second motor-generator, and a controller configured to operate of the assemblies in a split mode. The split mode includes the first driveline assembly being driven by the first engine without torque assistance from the first motor-generator and the second driveline assembly being driven by the second motor-generator without torque assistance from the second engine and includes the first motor generator providing electrical power to the marine vessel grid for consumption.
