40m Cutter Suction Dredger
This vessel is designed and constructed as a dismantle type non-self-propelled cutter suction dredger, suitable for dredging operation of soil type II~IV, including fine sand, clay, silt, coarse sand, etc., in inland water and coastal area. The hull of dredger is composed by five pontoons, including one main pontoon and four side pontoons. The pontoons are full steel welding and are combined together by specially designed connecting pieces for convenient dismantle and assembly.
