1. A power supply system for a water-bound facility, comprising:
an electrical shaft, wherein the electrical shaft is connectable to a first DC voltage bus for a first DC voltage and to a second DC voltage bus for a second DC voltage,
wherein the electrical shaft comprises at least one variable-speed generator, driven by an internal combustion engine, for producing a motor voltage having variable amplitude and variable frequency and at least one variable-speed drive motor that is supplied with this motor voltage and coupled to a propulsion unit,
wherein the first DC voltage bus is intended for a first DC voltage and the second DC voltage bus is intended for a second DC voltage, the first DC voltage being higher than the second DC voltage, and
a coupling between the first DC bus and the second DC bus, wherein electrical power is transported from a low-voltage DC voltage bus to a higher-voltage DC voltage bus in order to supply at least one electrical shaft with electrical power.
