When the ship operates with the heat recovery mode, Converteam uses the energy to boost the propulsion system by feeding a shaft induction motor supplied through a PWM MV7000 converter.
And the shaft induction motor can also be used as a PTO generator because of the full reversibility of the system.
Benefits of the PTO / Booster system with a shaft induction motor:
- higher overall efficiency rate
- increase in propulsion power
- simplicity, robustness and reliability of the induction motor
- flexible design and redundant system: minimized downtimes
- fuel saving: exhaust energy recovery
- swift return on investment.
