The energy consumption emissions and energy consumption costs of dredging ships are extrem-ely high.In order to accurately predict the energy consumption of dredging ships under the condition of mud,reduce energy loss,and reduce operating costs.The energy efficiency analysis prediction method based on the long-term memory(LSTM)network is used to use the real ship data collected by the sensor to perform the energy efficiency of the dredging operations,establish an energy efficiency analysis prediction and evaluation model,and provide an evaluation theory for the energy efficiency of dredging operations.The simulation results show that this method can accurately predict the trend of energy consumption of dredging ships.
