Cashman Dredging

What Cashman Dredging does

Cashman Dredging & Marine Contracting Company, LLC is a privately held U.S. marine contractor that provides integrated dredging and marine construction services to federal, state, municipal, and private sector clients. The company operates four core service lines: Navigation Dredging (harbor deepening and channel maintenance for Post Panamax vessels), Environmental Dredging (precision remediation of contaminated sediments), Beach Renourishment (shoreline reclamation), and Marine Drilling & Blasting (in-waterway rock removal). Cashman has completed the largest environmental remediation dredging project in U.S. history and routinely works in active federal harbors including Boston, New York, and Portland.

The company's technical platform is its specialized, capital-intensive fleet: the Dale Pyatt clamshell dredge (one of the largest buckets in the Western Hemisphere, ABS All Oceans certified), the Atchafalaya trailing suction hopper dredge (USCG Unlimited Oceans certified, 1,300 yd3 capacity), the Captain AJ Fournier and Jay Cashman backhoe dredges (IHC systems with GPS positioning), the ICARUS and Wood I bucket dredges, the Kraken drill boat (in-house designed with three specialized drilling rigs and dual RTK positioning), and the MJ Verrochi drill boat. Advanced positioning instrumentation (GPS, RTK, IHC) enables precision operations in challenging conditions. The Kraken's three-rig, single-pass drilling design is described as among the most efficient machines in the U.S.

Cashman operates a project-based business model, generating revenue through competitive bidding on government contracts and direct engagement with private clients. Distribution is direct enterprise field sales targeting federal agencies, state and municipal authorities, and private marine operators. Lead generation is passive, relying on industry reputation, ENR Top 400 Contractor recognition, and government procurement processes rather than traditional marketing. The company is part of the Jay Cashman, Inc. umbrella, which encompasses more than 25 affiliated companies across 8 industries. Headquartered in Quincy, MA, Cashman Dredging itself reports 251–500 employees, while the broader Jay Cashman organization reports 1,000+ employees and $500 million in annual revenues.
