Working method: The 2000m3/h 12Inch Cutter Suction Dredger will be moored with spuds or anchors while at work so that in essence the dredging operation takes place with the cutter in a stationary position.
Project aplications: Cutter suction dredgers are used wherever the seabed is hard rock. They are used for larger dredging projects such as navigation channels and port development and maintenance and land reclamation and in major projects such as the Panama Canal and the Suez Canal. KEHAN cutter suction dredgers are always used for land reclamation, Coastal protection, Sand and travel dredging to supply the construction industry, etc.
Types of dredging materials: Cutters are powerful and are capable of dredging all kinds of material in water including hard rock.
They are able to effectively dredge:
and sound (unfractured) rocks.
Advantage: The primary advantage of a CSD is that it is able to dredge hard materials that most trailing suction hopper dredgers cannot handle. KEHAN dredge machines are well known for their high efficiency and ultimate reliability.
CSD250 model of cutter suction dredger is one of the most mature and welcomed by Milestone's clients. Because they are characterised by high production rates and the ability to effectively handle a wide range of materials – silts, clays, sand, gravel, cobbles, and fractured and solid rocks. The most powerful cutters can dredge strong rocks effectively on a continuous basis.
