Based on a longstanding family of experienced marine professionals, Donjon Marine is an organization that is dedicated to and empowered by the strength of our people, our experience and the assets that allow us to always be in a position to manage any and all challenges - on sea and land.

Already a leader in dredging and marine salvage, Donjon continues to explore opportunities to expand our role in the marine industry and beyond.

Since its incorporation in 1966, Donjon Marine has established and continues to seek long-term client relationships in a world where limited business resources demand a constant balancing of expenditures. Beginning with its foundation in the New York area as a pioneer in marine salvage services, Donjon has grown to become a leader in both conventional and environmental dredging. Our areas of expertise also include recycling, land and marine demolition, pollution control and remediation, heavy lift transport, marine transportation and landfill remediation/site management.

With the creation of Donjon Shipbuilding & Repair, LLC, our latest addition to our family of services, Donjon controls the largest shipyard of its kind on the Great Lakes, utilizing years of experience and knowledge to meet the needs of an ever-growing industry to provide shipbuilding, dry-docking, ship repair, barge construction, vessel conversion, repowering, maintenance, steel fabrication, steel assembly, and other related services through the Great Lakes region and beyond.

As we continue to grow, Donjon and its affiliates maintain offices, assets and personnel throughout the Northeastern United States, with operations spanning the globe.
