The invention relates to a drive system (1) for a ship which has an onboard electrical system (2) with a fixed onboard electrical system frequency. The drive system (1) comprises an electric drive motor (10, 20) for driving the ship, a frequency converter (11, 21) via which electrical energy can be supplied from the onboard electrical network (2) to the electric drive motor (10, 20), a drive machine (13, 23), a drive generator (14, 24) which can be driven by the drive machine (13, 23), and an electric shaft (15, 25) for connecting the electric drive motor (10, 20) to the drive generator (14, 24). The electric drive motor (10, 20) can thereby be optionally driven by the frequency converter (11, 21), by the drive generator (14, 24), or by the frequency converter (11, 21) and the drive generator (14, 24). In addition, an operating mode is preferably provided, in which power generated by the drive machine (13, 23) is supplied into the onboard network (2) via the frequency converter (11, 21). |
