In view of the difficulty in controlling the traverse speed range of the cutter suction dredger during the construction process,this paper takes the dredging construction work in Panjin channel as an example,applies the analysis method based on the control chart to study the traverse parameters of the cutter suction dredger.This paper proposes the method of setting parameter range of traversing dredging operation based on the control chart,sets the cutter pressure and the suction vacuum of the underwater pump during the horizontal dredging operation in detail,and realizes the continuous quality control of the traverse operation during dredging.The results show that the method can provide a scientific and intuitive way to help operators to control the optimal parameter range so as to improve the ship’s productivity.
