The cutter suction dredger boasts wide adaptability, suitable for river, lake, and coastal port channel and harbor area construction. It is ideal for excavating sandy loam and silt. The new large cutter features heavy-duty cutterheads and wave protection equipment, making it applicable for挖掘weathered rock and hard substrates, as well as offshore construction.

However, there are certain situations where cutter suction dredgers are not suitable for use, such as:

Standard cutter suction dredgers are not suitable in rough weather conditions.

(2) Not suitable for areas with excessive flow rates.

(3) Difficulty in yielding to vessels in busy port channels and narrow waterways.

(4) Silt pipes cannot cross waterways or port areas.

(D) Excavation depth that exceeds the dredger's maximum draft or is less than the working water depth of the dredger is not suitable.
