The 4-inch Subdredge driving into a concrete-lined cooling water intake canal for the largest Power Plant in Mexico CFE. The Subdredge was able to pump material at solid rates of over 70% by volume and up to 150 cubic yards an hour of material.

All of this was accomplished with no divers and without having any affect on the liner. The sand was being pumped vertically about 60-feet and horizontally over 1000-ft.

General Information. The Subdredge is a remote operated submersible dredge that can be powered hydraulically or electrically. This video shows the subdredge at a concrete lined cooling pond. Unmanned and remote controlled. Pump sizes ranging from 4-inch up to 10-inch with production rates of up to 4500 GPM or 400 cubic yards of material per hour.

The Subdredge can be equipped with an umbilical that allows for it to operate remotely at distances of up to 1000-ft or greater from the operator.

The Subdredge is ideal for dredging applications that call for great depths, precision dredging, unmanned operation, and liner dredging to name a few. This dredge costs a fraction of the cost of conventional dredges and can handle a larger variety of dredging applications. Increased ROI by design.
