Abstract: The disclosure concerns a self-propelled ship comprising a shipboard electric network, a main electrical supply bus, propulsion means, a motor for driving the propulsion means, and means for supplying electricity to them. According to the disclosure, the supply means comprise a set of electric capacitors having a capacitance sized to provide, at their nominal electrical charge, at least temporarily, both of the nominal supply of the shipboard network and of the electric motor through the bus, and electrical connection means arranged on board the ship for connecting the set of electric capacitors to another electric network located at an arrival and/or departure point of the ship, for the purpose of recharging the capacitors to their nominal charge and to supply the first network during a stop at the arrival and/or departure point.
