Abstract: A vessel energy management system for controlling power supply to and from a propulsion system of a vessel. The energy management system has a motor-generator unit adapted to receive power from a prime mover of the vessel, a frequency converter, an energy storage unit, and a controller. According to different embodiments, the energy storage unit includes one or more capacitors, super capacitors or ultra capacitors. The controller determines an instantaneous power requirement of the propulsion system and an average power generated by the prime mover. A comparator compares the instantaneous required power and average power. If the instantaneous required power exceeds the average power, the motor-generator unit receives energy from the energy storage unit. If the instantaneous required power is less than the average power, the motor-generator unit supplies power from the prime mover to the energy storage unit.
