This paper introduces the application of aided design software based on MATLAB for the construction of floating booster station.Rationally designed of the floating booster station by the calculation results can avoid partial discharge pressure being too high after series connection of multistage mud pump of cutter suction dredger.It solves the technological problems that cutter suction dredger can’t construct in long-distance discharge because of the limitation of conveying distance.The research result has been successfully applied to the reclamation project of 50 million t/a coal wharf in Caofeidian.
