Sabine Marine Group Inc.

Gulf Copper & Manufacturing Corporation, doing business as Gulf Copper Dry Dock And Rig Repair, operates as a small business prime contractor providing maritime ship repair, maintenance, dry-docking, and vessel overhaul services to the Department of Defense and federal maritime agencies, with 100% of recent awards held as prime contracts and no subcontractor involvement. The Galveston, Texas-based manufacturer and service provider competes primarily under total small business set-asides across its portfolio.

Gulf Copper's customer footprint is heavily concentrated with the Department of the Navy's Military Sealift Command, which accounts for 31 of 39 prime awards (79% by count) and $233.9 million of combined potential value. The second- and third-largest customers by dollars are the Department of the Army Materiel Command TACOM Life Cycle Management Command ($529 million potential value on a single $529 million Army Watercraft Sustainment Maintenance award) and the National Oceanic and Atmospheric Administration ($77.7 million across two dockside repair IDVs). The gap between award count and dollar concentration reveals the MSC relationship's breadth: MSC issues frequent task orders for individual vessel repairs ranging from tens of thousands to several million dollars each, while the Army contract, though single-award, carries the bulk of the ceiling. The Department of the Navy Secretary of the Navy, Army Corps of Engineers, and Coast Guard round out the active customer set with minimal volume.

Gulf Copper holds four named parent vehicles anchoring its work. The $140 million East Coast General Ship Repair IDIQ with Military Sealift Command (multiple-award, total small business set-aside, through September 2028) generates the highest task-order volume at 20 delivery orders carrying $19.2 million in combined potential value. Gulf Copper also holds single-award and multiple-award IDVs: a $73.8 million NOAA dockside repair contract (total small business set-aside, through August 2028), a $15 million Military Sealift Command lay berth services IDC for two Expeditionary Fast Transport vessels (no set-aside, through January 2027), and a $44.6 million Military Sealift Command electrical services MAC IDIQ (total small business set-aside, through June 2030, awarded June 2025). Recent representative work on the MSC East Coast General Ship Repair IDIQ includes a $5.5 million habitability modification and voyage repair availability order on USNS Newport (August 2025), a $791 thousand voyage repair availability order for USNS Yuma and USNS Burlington (September 2025), and a $2.88 million USNS Spearhead deactivation order (May 2025). Non-MSC work includes a $4.2 million shipyard repair order from the Army Corps of Engineers for the multi-purpose vessel Brandy Station (November 2023) and a $1.6 million drydock and refurbishment order for the T.S. General Rudder training ship from the Department of the Navy (September 2021).

Activity has grown sharply, from one award in 2022 to 16 in 2025, with three awards appearing in 2026 year-to-date. The combined potential value of $848 million reflects the Army Watercraft Sustainment Maintenance IDIV ceiling; obligated dollars across the portfolio stand at $45.1 million (5% of potential value), indicating most awards carry substantial unexercised ordering authority. The recompete exposure is modest within the next twenty-four months because the largest-ceiling awards (the Army Watercraft Sustainment and East Coast General Ship Repair IDIQs) extend to 2028–2030. Gulf Copper's category footprint is overwhelmingly maritime: 36 of 39 awards fall under NAICS 327213 (Ship Building and Repairing), with secondary volume in port operations and engineering support services. Top PSCs include Non-Nuclear Ship Repair (East) and maintenance/repair of ship and marine equipment.

On Service Contract Inventory, Gulf Copper reported $7.7 million in invoiced federal services revenue across FY2022–FY2024 (5 SCI-reportable prime records covering the $150,000 reporting threshold), with 8.7 FTEs in FY2022, zero in FY2023, and 20.6 FTEs in FY2024. This trajectory reflects episodic large vessel repairs rather than continuous staffing. Government-paid hourly rates on federal services contracts ranged from a 10th percentile of $87.24 per hour to a median of $111.01 per hour to a 90th percentile of $255.60 per hour, reflecting a mix of labor classifications from craft technicians to specialized engineering support. Gulf Copper performs 100% of its SCI-reported prime work with its own delivery teams and carries no named subcontractor footprint in the sample, indicating a vertically integrated shipyard and repair operation leveraging its own dry-dock and fabrication infrastructure at Orange, Texas and Galveston facilities.
