Aiming at the problem of the construction and application of dredging equipment parameter standardization for trailing suction hopper dredger，based on the characteristics of dredging equipment and engineering experience，we use the method of comparison，induction，and standardization analysis，establish the standard of dredging equipment parameters for trailing suction hopper dredger. Combining with the actual construction case，we compare and analyze the actual measurement and theoretical calculation. The results show that the standardization of main dredging equipment parameters is very important for the control of dredging equipment characteristics and the improvement of dredging efficiency，which needs to be supplemented and improved continuously combining with engineering application to provide the references for dredging operation of trailing suction hopper dredger.
