METHOD FOR OPERATION OF A MARINE-VESSEL PROPULSION SYSTEM WITH WASTE-HEAT RECOVERY, AS WELL AS A MARINE-VESSEL PROPULSION SYSTEM WITH WASTE-HEAT RECOVERY

摘要

The problem that an unpredicted failing of the power generation by the waste-heat recovery system (20) can lead to interference with the power supply system or even to a blackout in the marine vessel, is avoided according to the invention in that, during motor operation of a shaft generator/motor (11) and in the event of a failure of the power generation by the waste-heat recovery system (20), the shaft generator/motor (11) is switched from motor operation to generator operation, with an energy source (17, 52) feeding electrical power into the marine-vessel power supply system (5) during the switching time, such that the voltage and frequency of the marine-vessel power supply system (5) do not fall below a respectively predetermined limit value.
