The large cutter suction dredger is employed to excavate deepwater channel rock without reef so as to avoid the damage of dredging to the environment. Cutter suction dredgers are usually needed to butt the mud pipeline so as to fill the dredged soil into land. When there is no suitable reclaimed area for blowing distance in deepwater channel, two kinds of construction technologies including the direct loading barge and stern blow loading barge can be used. This paper introduces a new excavated approach to excavate the dredged soil with channel rock by the large cutter suction dredger and discusses the generation and implementation process optimization of mobile stern blow loading barge, from which the conveying principle would be combed, refined and summarized, to serve as reference for and be popularized in similar projects.
