Electric propulsion system for ships | Wärtsilä

Saves fuel. At lower propeller speeds, the number of generators that are online can be adjusted according to the power demand. The engines will run more efficiently, which saves fuel. Lower emissions. The electrical propulsion system can lower emissions even with diesel generators. This is because the electrical propulsion system makes it possible to operate the generators within their optimal operational range even when the load from propulsion varies. Adopting electrical propulsion for a ship can significantly reduce the emissions of NOx/NO, CO, CO2, and soot. Low noise and vibration. Electric propulsion drives are unsurpassed for their quietness of operation. This is important for passenger comfort and research/special‑purpose missions. Redundancy. The propulsion system on the ship can be configured for better redundancy. This will makes the system more reliable. Smoother manoeuvring and positioning. The electric propulsion system has excellent dynamic characteristics. Changes in propeller speed and propeller reversals during manoeuvring and positioning can be carried out at optimum acceleration rates.
