Deep-mining Dredges Offer Performance Options


DSC Dredge’s Marlin class dredges are designed for deep-deposit mining, made possible by the use of an underwater pump system with a high-torque cutter drive assembly.

Digging depths range from 35 ft (10 m) to more than 200 ft (61 m). Discharge sizes range from 8 in. (203 mm) to more than 24 in. (610 mm). Marlin Class dredges are available in either a diesel- or electric-powered model to meet the customer’s specific needs. Drive systems include a Cat ACERT diesel engine with inline direct marine-style transmission for dredge pump reduction; or TEFC electric motor, variable-frequency AC dredge pump motor drive and double helical gear reducer for dredge pump reduction. All models feature a PLC operating system, magnetic flow meter, electro-proportional hydraulic circuits, high-capacity service water system, maximizer suction dilution valves and a three-wire mooring system. These performance features offer deep water dredging capabilities combined with a wide array of suction and discharge sizes to maximize operating efficiencies for any application.
