The energy-saving mechanism of the dredging slurry pipeline transport system was analyzed from three aspects： minimizing the pipeline energy consumption, raising the pump-station efficiency, and achieving the coordinated control of pump-stations. A working-point on-line dynamic optimization method and a multi-pump coordinated control strategy were presented. Based on the real-time measuring process data, the fuzzy decision method and the data fusion technique were used to optimize the working-point parameters dynamically, thus to obtain the lowest specific energy consumption of the slurry pipeline transport system. A general packet radio service （GPRS） based multi-pump coordinated control platform was constructed, which utilized the pump stations＇ real-time measuring process parameters and adopts fuzzy decision method to coordinate the pumps＇ control, thus to get the highest efficiency of the pump stations. Field experiments were carried out and the results showed that the proposal optimization method and the control strategy are easy to realize, the system devices are convenient to reconstruct, and good energy-saving performance can be obtained.
