Marlin Class dredge

Reserve, La., based DSC Dredge has made design improvements to its best selling Marlin Class dredge.

The Marlin Class underwater pump mining dredge is designed to meet the needs of deep mining applications and aggregate deposits by providing a more efficient tool for material excavation.

DSC builds each Marlin to the exact requirements of a particular operation and to handle a particular deposit—from sand and gravel to industrial minerals. The Marlin’s deep digging capability is made possible by the use of an underwater pumping system with a high torque cutter drive assembly. Digging depths range from 35 feet to more than 200 feet.

Discharge sizes range from 8 inches to more than 24 inches [600 mm] to allow for a wide range of production and flow conditions.


Currently under construction and coming available mid-2021, is DSC’s newly designed 14-inch single engine Marlin Class underwater pump mining dredge equipped with a 1,125 HP [839 kW] diesel engine. The newly designed Marlin dredge will have a 65-foot dredging depth capability, but, says DSC, the most talked about improvement is that it is now completely transportable via both trucks and intermodal shipping containers thus making freight cost efficient. In addition to premium features that already maximize operational efficiency, every Marlin Class Dredge can also incorporate all of DSC’s newly released technology including DSC Vision and Dredge Rx.

While the dredge’s Tier 4 engine is a new design, the Marlin Class dredge is still available with lower tier engines that can now be utilized by dredge owners and operators worldwide.
