EQUIPMENT
Mechanical Dredges
GLDD operates four of the largest mechanical clamshell dredges in the United States, as well as a barge mounted Liebherr 996 hydraulic excavator. These vessels operate on large load line certified spud barges and are utilized on a wide range of projects, including navigation channel and port facility improvements, maintenance dredging, demolition, pipeline excavation/burial, and slope revetment works. The dredges are capable of excavating a wide range of material. Dredged material is typically loaded into barges (scows), which transport the material to its final in-water or upland placement site. GLDD owns and operates a large fleet of material transport barges, a hydraulic barge unloader, and a drilling and blasting barge (drillboat) to support its mechanical dredging operations.
