Rising geopolitical tensions have cast a spotlight on both the fragility and strategic importance of America’s shipbuilding industry. U.S. shipyards serving inland, coastal, and defense markets have seen limited investment for decades. Now, with institutional capital searching for its next deployment opportunity, they are emerging as a compelling target for infrastructure and private equity investors. A combination of regulatory enforcement, new policy proposals, and the scarcity of both maritime infrastructure and skilled labor is fueling renewed interest in a sector that has long been overlooked.
POLICY SHIFT DRIVING INFRASTRUCTURE INVESTOR INTEREST
Regulatory and new policy proposals are contributing to growing investor interest and sentiment in both defense-oriented and commercially focused shipyards serving the inland marine sector.
The U.S. Coast Guard’s implementation and enforcement of Subchapter M have fundamentally altered demand dynamics for the inland marine sector. Introduced in 2016 after years of debate, the regulation mandates inspections, safety management systems, and stricter standards for inland and coastal vessels. While the rule was phased in gradually, enforcement has only now become more stringent. This has exposed a critical bottleneck: the U.S. lacks sufficient drydock capacity to both maintain existing fleets and support new vessel construction.
Drydocks are essential for inspection, repair, and maintenance activities required to maintain a vessel’s certification of inspection. For example, saltwater vessels must undergo drydocking and internal structural examinations twice within a five-year period, while freshwater vessels must be inspected at least once every five years. These processes can take weeks or months, depending on the scope of work and the vessel’s age. When a vessel cannot access drydock space in time, it risks being taken out of service, directly impacting operator revenues. This pressure is particularly acute for tank barges serving the petrochemical sector. With a finite number of eligible tank barges in service and a significant share of the fleet approaching their five- and 10-year inspections simultaneously, the industry lacks sufficient drydock capacity to efficiently manage this demand.
Drydock availability limitations create a cascading capacity constraint. As government investment flows into domestic infrastructure to build more U.S.-flagged and Jones Act vessels, demand will strain existing capacity further in the near term, an imbalance that, by industry estimates, is likely to persist for years.
Since infrastructure funds generally have longer investment cycles than private equity, they are well-positioned to capitalize on shipbuilding’s long-term demand cycle. An infrastructure fund that invests in or revitalizes a shipyard can easily and readily create drydock capacity to support newbuild, repair, and maintenance work. The life of a drydock can exceed 50 years, so a one-time investment in fixed infrastructure can prove to have a very attractive return profile, particularly given the long-term nature of newbuild vessel contracts.
Benefiting the defense sector, the SHIPS Act is aimed at revitalizing the U.S. shipbuilding industry, particularly in larger shipyards focused on Navy and Coast Guard vessels. This bipartisan legislation is creating momentum for investment in the industry as it has brought attention to a previously overlooked sector of domestic manufacturing. It will take a while for capital to be deployed from the government, so large shipyards won’t immediately feel the impact of this new policy, but this just elongates the supply/demand imbalance of shipyards and vessel operators. Large yards will likely prioritize new construction over repair and maintenance work from awarded government contracts. This, in turn, will push smaller vessel construction, along with repair and maintenance, to small to midsize yards and create a cascading effect across the shipyard ecosystem.
Against this backdrop, small and midsize shipyards are particularly well-positioned in this environment. These facilities are critical for commercial repair and maintenance work, which typically offers faster turnaround times and strong margins. In addition, many smaller yards can support larger shipyards by fabricating components for both commercial and government vessels, which are then transported and assembled at facilities with deeper water access. This creates opportunities for smaller yards to participate in long-term contract-driven work tied to government programs, which also provides a hedge against the potential for cyclical variability in commercial vessel construction.
LONG-TERM INVESTMENT PROFILE
Infrastructure investors, while better suited to long-duration assets, have historically focused on larger-scale opportunities such as ports, pipelines, and transportation networks. Only recently have they begun to recognize shipyards as a viable infrastructure asset class. High-profile transactions, such as Antin Infrastructure’s acquisition of Vigor, signal a growing willingness to deploy capital into the sector. At the same time, larger, strategically important yards, including government-owned and Class 1 facilities such as the Hanwha-owned Philly Shipyard, are attracting both strategic and institutional capital.
For investors, these dynamics position shipyards as an increasingly attractive infrastructure asset. While there is capital intensity with regard to the shipyard, once updated, the longevity of the equipment and machinery requires very low levels of recurring maintenance capex. Once modernized, core shipyard infrastructure benefits from long useful lives and generally predictable maintenance capital expenditures, although equipment upgrades and regulatory requirements can drive periodic reinvestment. In addition, higher-velocity repair and maintenance work can generate significant short-term margins/returns with a lower capital outlay.
The durability of demand further strengthens the investment case. Vessels themselves have long operational lifespans and can be repowered or refurbished to extend their use. At the same time, shifts in end markets can trigger entirely new build cycles. Similar structural changes in energy, logistics, and defense are likely to drive future demand.
Initial investment in a yard, once completed, can be leveraged for many years and has very positive free cash flow conversion characteristics. For example, once buildings, overhead cranes, yard machinery, and facilities are up to date, operating costs are variable, with very little recurring investment required for this fixed infrastructure. A well-run shipyard can generate mid 20s – 30s percent EBITDA margins and generate free cash flow (EBITDA less capex) in excess of 90%.
In addition to a shipyard’s operating characteristics, its location can also be a strategic asset to vessel operators who rely on the yard for continued repair, maintenance, and inspection work. An example of this would be a shipyard on the Gulf Intracoastal Waterway that serves both the inland towboat and barge fleet as well as offshore vessels. A well-positioned yard limits transit time for the fleet operators moving their vessels in for repair, resulting in lower operating costs as well as increased uptime. The combination of these factors creates a steady flow of demand and a recurring revenue base for the yard.
FUTURE INVESTMENT LANDSCAPE AND OPPORTUNITIES
Early adopters who recognize the need for revitalized shipyard infrastructure to support new vessel build programs have committed to the sector through recent transactions. These deals highlight both the imperative to modernize large yards and growing investor interest in smaller yards that can be combined to form coordinated groups of non-contiguous shipyards with the scale and capabilities to attract commercial and government contracts (e.g., Edison Chouest Offshore). As institutional investors add shipyards to the menu of viable investment opportunities, the sector will ultimately mature into an asset class with a more frequent trading cadence.
French infrastructure fund Antin Infrastructure Partners announced in February its plan to acquire shipbuilding and repair company Vigor Marine Group. In August 2025, Cerberus Capital Management entered into a strategic partnership with HD Hyundai to launch a new maritime investment strategy, Cerberus Maritime. These investments focus on larger vessel construction and repair, and are evidence of early movers entering the space.
On the strategic side, Hanwha’s acquisition of Philly Shipyard stands out as one of the largest investments in an active large U.S. commercial shipyard. The South Korean company acquired the yard in 2024 for $100 million and plans to invest an additional $5 billion to revive commercial shipbuilding capacity at the site.
And more recently, private equity firm Wynnchurch announced its acquisition of Arcosa’s inland barge business (Arcosa Marine Products Inc.) for $450 million. Arcosa has been a critical part of the barge manufacturing industry serving the inland waterways for over 120 years.
As the SHIPS Act and other policy initiatives continue to draw attention to the maritime sector, investors will refine their investment theses accordingly. The U.S. Navy is requesting a 46% increase over last year’s shipbuilding budget — rising to $65.8 billion for combat and noncombat vessels — in a move aimed at revitalizing U.S. shipyards to counter China’s dominance. Building large military vessels will also require support vessels, ship-assist tugs, and various other auxiliary craft. As a result, capital will flow into the sector across all vessel classes, including large, coastal, and inland Jones Act vessels. As smaller yards combine to form well-coordinated, non-contiguous groups capable of handling this demand, infrastructure funds will increasingly view shipyards as a scalable and actively traded asset class.
Looking ahead over the next five to 10 years, well-capitalized, well-maintained modern yards capable of handling newbuilds required to support U.S. Coast Guard and Navy programs under the SHIPS Act will be prime acquisition targets. Non-contiguous yards that can be utilized for complete builds, repair and maintenance, and component construction for both commercial and government vessels will attract strategic and financial buyers alike. Finally, for infrastructure investors managing a portfolio of shipyards, securing a mix of commercial work and long-term government contracts will provide the resilience needed to weather fluctuations in market conditions.
