GLDD

Great Lakes Dredge & Dock Corporation is a provider of dredging services. The Company is also engaged in developing offshore wind energy. The Company operates three types of dredging equipment: hopper dredges, hydraulic dredges, and mechanical dredges. Its dredging generally involves the enhancement or preservation of the navigability of waterways or the protection of shorelines through the removal or replenishment of soil, sand, or rock. Domestically, its work generally is performed in coastal waterways and deep-water ports. Its United States dredging market consists of four primary types of work: capital, coastal protection, maintenance and rivers and lakes. The Company's capital dredging consists primarily of port expansion projects. The Company's domestic dredging fleet is positioned on the East and Gulf Coasts, with a smaller number of vessels positioned on the West Coast, and with many of the rivers and lakes dredges on inland rivers and lakes.
