The permissible dredging depth for cutter suction dredgers generally ranges from 25 to 30 meters; however, large-scale vessels equipped with high-power excavation equipment and suction pumps can achieve dredging depths of up to 50 meters. Regarding the over-width range, specifications vary depending on the specific vessel model and operational conditions; generally, for cutter suction dredgers with a cutter head diameter exceeding 2.0 meters, the maximum permissible over-width is 1.5 meters.
In dredging operations, the permissible depth range for cutter suction dredgers is typically 25 to 30 meters. However, large vessels equipped with high-power excavation equipment and suction pumps can reach impressive dredging depths of up to 50 meters. The over-width range is influenced by multiple factors, including the vessel type, operational conditions, and soil characteristics. Generally, for cutter suction dredgers with a cutter head diameter greater than 2.0 meters, the maximum permissible over-width is 1.5 meters.
