| Abstract: | This paper analyzes the propulsion system of 4 500 m^3 trailing suction hopper dredger, through actual measurement for main machine, learning about its operating condition after using for several years. Under the premise of the invariable shafting and adjustment mechanism, designing a new ducted CPP to replace its original controllable propeller, the comparative study based on theoretical calculations and measurement on site shows that this reform increases the thrust force of the dredger and with better economic benefits to save energy and improve efficiency. |
