All of our dredges are "flare" dredges. The flare dredges are easily distinguished from the dredges that use a hopper, or "header box", in that they incorporate a large expansion chamber or "flare" which is located between the dredge's power jet and the sluice box. .
Support equipment for these dredges includes over 55,000 of discharge pipe, four custom built barges for moving anchors and performing service work, multiple support boats, booster pumps, a vast array of special rigging and tooling, land based support equipment, 2 hopper barges, a long reach excavator, portable barges, a marsh excavator, air boat, and more.
The dredge sucks gravel, sand, and rocks off the river bottom and discharges the slurry into a sluicebox. A flexible plastic hose with an intake nozzle is directed at the riverbed deposition while the floating dredge train downstream. The dredge works much like a vacuum cleaner as the operator moves the nozzle in a sweeping motion upstream.

Trailing suction hopper dredgers are equipped with one or two suction pipes ending in drag heads. The drag head moves slowly over the bed collecting the sand like a giant vacuum cleaner. The mixture of sand and water is pumped into the hopper of the dredging vessel. Excess water flows out through socalled overflows.
The grab dredger is the most common used dredger in the world, especially in North America and the Far East. It is a rather simple and easy to understand stationary dredger with and without propulsion. In the latter the ship has a hold (hopper) in which it can store the dredge material, otherwise the material is transported by barges.
