Hybrid drive system for more efficiency

With a diesel-electric hybrid drive, the ship's propellers are powered electrically by converter-fed synchronous motors which receive their energy from diesel generators. Numerous advantages make the combination of diesel engines and electric motors particularly attractive for shipping. In addition to significantly reducing fuel consumption, by up to 28% in flowing water, noise and vibration can also be reduced.

A further advantage lies in the improvement of the overall efficiency by reducing the power output of the diesel engine, i.e. traveling in the optimum speed range. For instance, only a low power level is required for ships that need to maneuver precisely out on the open sea or that need to keep to a fixed deployment location. With a pure diesel drive the speed in these cases is massively reduced when compared to the previous, faster moving journey. This means the engine isn��t operating in its ideal efficiency range. By contrast, when an electric drive is used in these situations, the frequency converter controls the propeller speed directly via the synchronous motor, thus enabling it to run far more slowly. Since synchronous motors achieve high efficiency even at low speeds, the electric mode saves fuel.
