CCCC has independently developed the world's largest dual-fuel trailing suction hopper dredger by hopper capacity and Asia's largest cutter suction dredger, as well as technologies such as open-sea artificial island construction and ultra-long discharge distance. As a result, its large-scale dredging equipment technology has reached an internationally leading level. These achievements not only support major domestic projects but are also reshaping the international dredging market with Chinese standards in projects such as Pakistan's Gwadar Port and Peru's Chancay Port.
