5. Conclusion

Numerous power and propulsion systems are available. This article describes modern and classic solutions for on-board power generation and propulsion systems combining converters, machines, electrical networks and protection devices. These solutions are used mainly on cruise ships, cargo ships and specialized vessels (research vessels, cable-layers, tugs, military ships, etc.).

The overall architecture of the energy-propulsion system, and the choice of components that make it up, are essentially determined by the vessel's power range and mission profile.

Strong constraints on pollutant emissions and advances in battery energy storage capacity have led to renewed interest in DC distribution networks.

Numerous examples of such vessels attest to this, particularly in the intermediate power ranges.
