The hopper dredge Wheeler docks by the headquarters for the U.S. Army Corps of Engineers, New Orleans District, located along the east bank of the Mississippi River in New Orleans, La.
The largest hopper dredge in the USACE fleet, the Wheeler keeps waterway channels clear from Key West, Fla., to Brownsville, Texas. Although the dredge is maintained in a state of readiness for worldwide operations, it spends the majority of its time operating in Louisiana in the Southwest Pass of the Mississippi River, dealing with shoaling problems that occur during high and low water.
Known as a "trailing suction" hopper dredge, the Wheeler operates much like a giant vacuum cleaner. To dredge a channel, the Wheeler lowers its three, uniquely-designed drag arms over its side to the channel bottom. While the vessel travels forward at a speed of approximately two knots, the drag arms suck a water and sand mixture, known as slurry, from the channel bottom. The slurry passes through the drag heads and pipelines into the hopper.
The dredged material is transported from the channel being maintained and then deposited in an authorized Dredge Material Containment Area.
