Dredging

Dredging promotes efficiency as much as a well-functioning terminal does.  Nelosca can provide both mechanical and hydraulic dredging options that will maintain the needed depths for efficient navigation. 
From mass removal to surgical dredging, we have the ability to right-size our operation for your project needs.  This includes projects that may involve rapid dewatering and disposal in offsite locations.  Our dredges are outfitted with state-of-the-art navigational and dredge monitoring equipment, so we know exactly how much material we are digging at any given point.  

Nelosca also offers hydraulic dredging for mass removal situations.  In this case, material can be dug using a cutterhead, or hydraulic dredge, and transported long distances to a dewatering or disposal site.  Our dredges range in sizes from an 8-inch discharge, all the way up to a 16-inch discharge.  These dredges are portable and can be easily transported from one body of water to another.

Material transport is also sized for the project.  Every project is different, and to maximize value there must be a high level of flexibility. Nelosca can offer several methods of material transport including barge transport, hydraulic pipeline transport, or a combination of both to safely support dredge operations of all sizes.

Typically, areas designated for spoils and dewatering are limited in size, creating difficulties for material disposal. Nelosca has specialized equipment to speed the dewatering process, eliminating the need for
large settling ponds.  Nelosca can manage an effective rapid mechanical dewatering operation that will allow ground transport of sand and sediment.  We can also build and manage a passive dewatering system such as retention ponds and geotextile tubes field.
