Variable speed power generation can provide up to 6 % annual fuel savings with diesel electric propulsion, when the operational profile of the vessel has a lot of variation in speed and power demand.
The Dynamic AC (DAC) concept by ABB enables to optimize the total fuel consumption in the vessel by adjusting the rotational speed of the diesel generating sets and allowing the system frequency to vary within the specified range. Integration with the power management and advisory systems assures high level of optimization and provides tools for continuous improvement during the whole life cycle of the vessel.
