In view of the problems of poor construction quality and low construction efficiency when the trailing suction hopper dredger implements special projects such as slope excavation and sweeping. Based on the dredge track presentation system，we establish the ship，channel，and digital terrain models. Through the engineering application，we analyze the construction quality and efficiency of special projects under its 3D visualization function. The results show that the dredge track presentation system，i.e. the dredging navigation and operation visualization auxiliary system is of great significance for ensuring construction safety and construction quality，and promote the construction efficiency of dredging engineering.
