The invention relates to a state prediction method and device for a ship engine dredge pump, computer equipment and a storage medium, and belongs to the technical field of ship engine monitoring. Themethod comprises the steps of obtaining dredge pump monitoring data; wherein the dredge pump monitoring data is determined according to collection data, sent by the collection equipment, of a ship engine mud pump; obtaining degradation speed and state evaluation data of the ship engine dredge pump; wherein the degradation speed is determined according to historical monitoring data of the ship machine dredge pump; wherein the state evaluation data is determined according to fault characteristics of the ship machine dredge pump; determining dredge pump prediction data of the ship engine dredge pump according to the dredge pump monitoring data and the degradation speed; and comparing the mud pump prediction data with the state evaluation data, and determining a state prediction result of theship machine mud pump according to a comparison result. According to the technical scheme, the problem that ship machine dredge pump state prediction is low in accuracy is solved. The state predictionresult of the ship engine dredge pump can be automatically determined, and the state prediction accuracy of the ship engine dredge pump is effectively improved.
