Norfolk Dredging Company

What Norfolk Dredging Company does

Norfolk Dredging Company is a family-owned, privately held marine infrastructure contractor founded in 1899 and headquartered in Chesapeake, Virginia. The firm specializes in hydraulic and clamshell dredging, with particular capability in subaqueous trench and tunnel excavation, hydraulic landfill and backfill, beach re-nourishment, and maintenance of shipping channels and harbors. Its customer base is concentrated in U.S. federal and municipal agencies — including the Naval Facilities Engineering Command (NAVFAC), the U.S. Army Corps of Engineers, and multiple port authorities (Charleston, Savannah, Delaware River, San Juan, Baltimore) — with additional private-sector work for industrial facilities such as LNG terminals.

The company operates an extensive specialized fleet built around five cutterhead dredges (Dredge Delaware at 30 inches/19,000 HP, Dredge Charleston at 24 inches/10,000 HP, Dredge Essex at 6,100 HP, Dredge Chesapeake at 24 inches/3,235 HP, and Dredge Jekyll Island at 14 inches/1,450 HP), three clamshell dredges (Dredge Baltimore at 75 cubic yards, Dredge Atlantic at 38 cubic yards, and Dredge Virginian at 30 cubic yards), a fleet of ABS Class A1 split-hull dump scows, ocean-certified tugs rated 1,200-3,200 HP, and pipeline/booster infrastructure capable of pumping material over 65,000 feet. Documented performance includes 3,000,000+ cubic yards pumped over 28,000 feet for the Southern LNG project, 1,000,000+ cubic yards removed at Norfolk Naval Station to support the USS Gerald R. Ford, and trench excavation beyond 90 feet to tight tolerances for the New Midtown Tunnel program.

Revenue is generated almost entirely through project-based contracts awarded via competitive bidding to government and, to a lesser extent, private clients across the U.S. Atlantic Coast, Gulf of Mexico, and Caribbean. Pricing is not publicly disclosed and varies by project scope, equipment, and duration. The company employs 101-250 people, retains a long-tenured management team (President in place since 1999, EVP since 1993, VP since 1983), and pursues work through direct enterprise field sales rather than channel partners or digital marketing.
