Callan Marine

What Callan Marine does

Callan Marine, Ltd. is a privately-held, family-owned dredging and marine construction company headquartered in Galveston, Texas, founded in 2009. The company provides comprehensive dredging and marine construction services to federal, state, and local government agencies and private commercial clients, primarily across the Gulf Coast region of the United States. Its services span four core categories: dredging services (maintenance, new work, environmental, and beneficial use); marine construction (pile driving, pier and wharf construction, cofferdams, drilled shafts, sheet pile structures); environmental construction (reef creation, wetlands conservation, shoreline protection, beach re-nourishment); and levee construction and management.

The company operates a specialized fleet of seven cutter suction dredges (CSDs) ranging from 12" to 32" in suction and discharge diameter: General MacArthur and General Arnold (each 290ft with 24,000+ installed horsepower and 97ft dredge depth capability), General Bradley (28" CSD, 9,260 hp), General Marshall (18" CSD, 3,005 hp), General Patton (16" CSD, 3,000 hp), General Pershing (18" CSD, 1,500 hp), and General Eisenhower (12" CSD, 1,500 hp). The dredging fleet is supported by extensive marine construction assets, including Manitowoc cranes up to 300-ton capacity, five barges, four tug boats up to 1,400 hp, pile driving hammers up to 100,000 lbs/ft, deck winches, and six compressors. The General Bradley and General Arnold carry production automation and monitoring systems, USACE Dredge Quality Management System certification, and US Coast Guard AIS integration with Hypack/Dredge Pack survey software.

Callan Marine generates revenue through project-based contracts secured via competitive bidding on government procurement processes and direct engagement with private port operators, terminal companies, and industrial clients. Named customers include the Texas General Land Office (Old Queen Isabella Causeway Demolition and Artificial Reef Project), Texas Department of Transportation (Port Bolivar Ferry Landing maintenance dredging), Galveston Wharves, Texas International Terminals (new ship berth construction), and the City of Beaumont (Riverfront Park restoration). Pricing is project-specific and not publicly disclosed. The company employs 11–50 staff supported by an experienced management team with over 200 years of combined large-dredging experience, with senior leaders recruited from Great Lakes Dredge & Dock, Orion Marine Group, Bean Companies, and the U.S. Army Corps of Engineers.

Direct peers

• Great Lakes Dredge & Dock Company: Largest U.S. dredging contractor (Nasdaq: GLDD), operates the country's biggest hopper and CSD fleet and is the dominant bidder on USACE and Gulf port deepening work. Direct comparison for Callan Marine's CSD-based capital dredging and channel maintenance business, with broader scale and geographic reach.
• Weeks Marine: Privately held, family-owned dredging and marine construction company with hopper dredges, CSDs, and heavy marine construction assets serving the U.S. East Coast, Gulf, and Caribbean. Closely mirrors Callan Marine's business mix, customer base, and family-operator profile.

Partial overlap with Callan Marine's environmental and shallow-draft dredging services for commercial and government clients.
