The Navy awarded Conrad Shipyard LLC a $122,400,000 firm-fixed-price contract modification on May 13 to design and construct four Yard Repair, Berthing, and Messing vessels, commonly referred to as YRBMs. Conrad Shipyard is based in Amelia, Louisiana, on the Atchafalaya River — a longstanding center of commercial and government shipbuilding activity in the Gulf Coast maritime industrial region. Work is expected to be completed by July 2029. The contract is administered by the Naval Sea Systems Command, which manages the Navy's YRBM program as part of its broader floating plant and harbor craft portfolio. The four new YRBMs will be distributed to homeport and forward-deployed locations where they serve as the primary maintenance and berthing infrastructure for submarines and surface combatants undergoing intermediate-level repair work.
What YRBMs Do and Why They Matter
Yard Repair, Berthing, and Messing barges are non-self-propelled floating platforms that provide a full suite of shipyard support services alongside a moored vessel undergoing maintenance. They carry machine shops, welding equipment, electrical repair spaces, berthing for maintenance personnel, and messing facilities that allow a maintenance crew to live and work aboard the YRBM while their host ship is alongside. YRBMs are the workhorses of intermediate-level maintenance — the category of repair that falls between the routine maintenance a ship's crew performs at sea and the complex overhauls that require dry-dock facilities at a Naval Shipyard or a private shipyard under a Availabilities contract. Without YRBM support, ships requiring intermediate-level electrical, mechanical, or structural repairs would need to queue for dry-dock time or return to their homeport, imposing availability costs and schedule delays that reduce fleet readiness directly.
The Navy's YRBM fleet has aged significantly. Many of the barges currently in service were built in the 1970s and 1980s and have been extended through multiple service-life extension programs that are increasingly expensive to sustain. The four new YRBMs contracted to Conrad Shipyard are part of a recapitalization effort to replace the oldest members of the YRBM fleet with modern platforms built to current standards for habitability, electrical generation, shop equipment, and environmental compliance. The firm-fixed-price contract structure is appropriate for a relatively well-defined ship construction requirement like a YRBM — unlike warship new construction programs involving complex combat systems integration, YRBM construction is primarily a commercial-grade shipbuilding and outfitting task where the design envelope and technical risk are manageable on a fixed-price basis.
Conrad Shipyard and the Gulf Coast Shipbuilding Industrial Base
Conrad Shipyard LLC is a Louisiana-based commercial and government shipbuilder that has been building marine vessels on the Atchafalaya River for decades. The company is part of the Conrad Industries family of shipbuilding companies and has experience constructing a range of Navy and Coast Guard support vessels — tugs, barges, and floating plant — alongside its commercial offshore support vessel and inland waterway barge work. Its selection for the YRBM contract reflects both its competitive position on price in a firm-fixed-price procurement and its track record of delivering similar floating plant to NAVSEA on schedule. Louisiana's Gulf Coast shipbuilding region includes a concentration of small-to-mid-sized shipyards — Conrad, Bollinger, Signal International, VT Halter Marine — that have historically provided the Navy with harbor craft, floating plant, and smaller combatants while the large naval shipyards at Newport News, Groton, Marinette, and San Diego focus on capital warships.
The $122.4 million contract is substantial for a Gulf Coast commercial shipyard and represents a significant portion of Conrad's government work portfolio. The four-vessel construction program creates sustained workload at the Amelia facility for approximately three years, providing schedule predictability that commercial shipbuilders value in their workforce planning and supply chain commitments. Gulf Coast shipbuilders have been increasingly competitive for Navy floating plant work as NAVSEA has modernized its procurement approach for this vessel category, using firm-fixed-price contracts that reward efficient commercial shipbuilding practices rather than cost-plus arrangements that can inflate program costs.
What It Means for Contractors
The YRBM contract award illustrates the diversity of the Navy's acquisition portfolio — alongside multi-billion-dollar carrier and submarine programs, the Navy regularly procures floating plant, harbor craft, and support vessels that are accessible to regional commercial shipbuilders with established maritime construction capabilities.
- Gulf Coast and Great Lakes shipyards that have not engaged NAVSEA's Program Executive Office for Ships (PEO Ships) or NAVSEA's Ship Acquisition Program Managers for floating plant should review the NAVSEA acquisition forecast for upcoming YRBM, yard oiler, tugboat, and similar harbor craft competitions; these are among the Navy's more accessible construction procurements for non-naval shipbuilders.
- Suppliers of marine diesel generators, ship service electrical systems, HVAC systems for habitability spaces, and machine shop equipment should engage Conrad Shipyard's procurement office directly for subcontracting roles on the four-vessel YRBM build; these systems have long lead times and early supplier selection gives Conrad schedule certainty for the July 2029 delivery commitment.
- NAVSEA's Small Business Industrial Base Office maintains a naval shipbuilding industrial base strategy that identifies supply chain gaps and provides market research to match small business capabilities with acquisition opportunities; firms seeking to enter the naval shipbuilding supply chain should contact this office for guidance on how to position for upcoming competitions.
- The YRBM program's recapitalization is ongoing; Conrad's four-vessel contract is likely not the final order, and firms that build supplier relationships now will be positioned for follow-on production contracts as additional YRBMs are funded in future budget cycles.
NAVSEA Floating Plant Recapitalization Strategy
The four Conrad YRBMs are part of a broader NAVSEA effort to modernize its floating plant inventory — a category of support vessel that includes not only repair barges but also yard oilers, ammunition barges, personnel ferries, and salvage pontoons that are essential to operating naval bases and forward-deployed logistics sites. The floating plant fleet suffered from decades of deferred recapitalization as defense budgets prioritized shipbuilding and aircraft procurement over logistics infrastructure, and by the mid-2010s the average age of many floating plant vessel types had reached 40 or more years. NAVSEA's Program Executive Office for Ships moved toward competitive commercial shipbuilding contracts as the preferred acquisition strategy — recognizing that the commercial marine market produces equivalent capability at lower cost than programs burdened by military specifications. The Conrad YRBM contract exemplifies this approach: a firm-fixed-price award to a competitive commercial shipbuilder, structured around commercially available marine systems, at a per-vessel cost that is significantly lower than what the same capability would cost if acquired through the naval shipbuilding industrial base. The program is expected to continue with follow-on YRBM orders as Congress funds the floating plant account.
