Methodology
This investigation draws exclusively from public-record sources. No anonymous sources were used. Findings are linked to primary documents wherever available.
Step 1 — Louisiana Court Records and Federal Maritime Litigation Documents
We reviewed Louisiana state court records and federal maritime litigation documents from Avondale-related cases across multiple decades. Avondale Industries and its successors appear as named defendants in hundreds of mesothelioma and asbestosis cases filed in Louisiana state courts and in federal maritime jurisdiction. These records include trial transcripts, jury verdicts, appellate decisions, and settlement records, all of which are public record under Louisiana’s rules of court.
Step 2 — OSHA Inspection Records and Internal Safety Memoranda
OSHA inspection records for the Avondale facility in Westwego, Louisiana were reviewed through the agency’s Integrated Management Information System (IMIS). Internal safety memoranda produced in Avondale Industries litigation — documents that became part of the court record through discovery proceedings — were also reviewed. These include industrial hygiene reports, fiber count measurements taken in shipyard spaces, and internal communications among Avondale safety personnel and management regarding asbestos hazards.
Step 3 — Louisiana First Circuit Court of Appeal Decisions, Trust Fund Records, and Deposition Transcripts
Louisiana First Circuit Court of Appeal decisions addressing the intentional act doctrine in Avondale cases were reviewed in full. Trust fund administrator records, published claim criteria, and payment schedules from asbestos trusts connected to Avondale predecessor entities were also reviewed. Deposition transcripts of Avondale safety officers and workers — produced as exhibits in litigation and incorporated into appellate records — provided direct evidence of workplace conditions and the company’s internal knowledge of the asbestos hazard.
Finding 1 Scale of Operations and Asbestos Use at Avondale (1938–2002)
Avondale Shipyards, located in Westwego, Louisiana on the west bank of the Mississippi River just outside New Orleans, was one of the largest shipbuilding operations in the United States. At peak operations the yard employed over 25,000 workers, making it the dominant industrial employer in the greater New Orleans region for much of the mid-twentieth century. The facility built Navy vessels, cargo ships, and offshore supply boats from its founding in 1938 through its operational wind-down in the early 2000s.
Asbestos was not incidental to Avondale’s operations — it was built into every major system of every vessel constructed at the yard. Pipe and boiler insulation throughout the ships used asbestos-containing lagging products applied by Avondale’s own insulator workforce. Sprayed-on asbestos fireproofing was applied directly to new hull sections as part of the construction process through the early 1970s. Gaskets and packing used in high-pressure fittings and valves throughout the vessels contained asbestos fiber. Deck coatings and certain structural adhesives added to the cumulative burden of asbestos-containing materials present throughout the shipyard at any given time.
The exposure risk was not uniform across trades. Workers who spent their days directly handling, cutting, mixing, or applying asbestos insulation products — particularly pipefitters, insulators, and boilermakers — faced sustained high-concentration exposures in the confined spaces of partially completed ship hulls. Workers in adjacent trades, including welders, sheet metal workers, and electricians, faced significant bystander exposures as asbestos dust released during insulation work permeated enclosed hull sections. The table below summarizes exposure patterns by job category based on product identification records and deposition testimony from Avondale litigation.
| Job Category | Primary Asbestos Exposure | Fiber Level Risk | Active Period |
|---|---|---|---|
| Pipefitters / Insulators | Pipe lagging with Unibestos and Kaylo products; direct handling, cutting, and application in confined hull spaces | Extreme | 1938–1980 |
| Welders | Adjacent to insulation removal and installation; asbestos dust liberation during nearby lagging work in enclosed spaces | High | 1945–1980 |
| Sheet Metal Workers | Duct wrap installation using asbestos-containing materials; cutting and fitting in enclosed mechanical spaces | High | 1945–1978 |
| Electricians | Conduit and panel insulation; asbestos-containing wire and cable insulation in early periods; bystander dust exposure | Moderate | 1945–1975 |
| Boilermakers | Boiler insulation block removal and replacement; asbestos packing in steam system valves and fittings | Extreme | 1938–1980 |
| Painters | Sprayed asbestos coatings applied to hull sections; overlap with fireproofing operations in newly constructed vessel spaces | High | 1955–1973 |

Finding 2 The Asbestos Products Used at Avondale
Shipyard records produced during Avondale Industries litigation documented the specific asbestos-containing products purchased and used at the Westwego facility. Purchase orders, invoices, and product identification records placed into evidence across dozens of individual cases established a detailed inventory of the materials that exposed Avondale workers to asbestos fibers over more than four decades of shipbuilding operations.
The predominant pipe insulation products were Unibestos, manufactured by Pittsburgh Corning Corporation, and Kaylo, manufactured by Owens-Illinois. Both products were widely used across the American shipbuilding industry during the mid-twentieth century and are among the most extensively litigated asbestos insulation products in the country. Pittsburgh Corning and Owens-Illinois have both been subjects of massive bankruptcy proceedings related to asbestos liability. Thermobestos, manufactured by the Philip Carey Company, was also used at Avondale from the early post-war period through the mid-1970s.
Perhaps the most acutely dangerous exposure source at Avondale was sprayed-on asbestos fireproofing applied to new hull sections. This material — from product lines associated with W.R. Grace & Company and predecessor formulations — was sprayed onto structural steel in enclosed ship compartments during construction, releasing enormous quantities of fine asbestos fibers into the air. Workers who performed this application, as well as nearby workers in the same hull sections, were exposed to fiber concentrations that later industrial hygiene measurements and expert testimony in litigation documented as among the highest recorded in any industrial setting.
| Product Name | Manufacturer | Product Type | Years Used at Avondale | Asbestos Content |
|---|---|---|---|---|
| Unibestos | Pittsburgh Corning Corporation | Pipe covering / insulation | 1948–1972 | 85% chrysotile and amosite blend |
| Kaylo | Owens-Illinois | Pipe covering / insulation | 1952–1968 | Approximately 15% amosite asbestos |
| Thermobestos | Philip Carey Company | Pipe covering / insulation | 1945–1975 | Chrysotile blend (varied by formulation) |
| Block Insulation | Multiple suppliers | Boiler and steam system insulation | 1938–1980 | Varied; amosite and chrysotile common |
| Sprayed Fireproofing | W.R. Grace & Company / predecessors | Hull coating / structural fireproofing | 1955–1973 | Up to 50% chrysotile asbestos |

Finding 3 The Concealment — What Avondale Knew and When
Internal Avondale safety memoranda produced in litigation established a timeline of corporate knowledge of the asbestos hazard that was damning in its clarity. Plant safety officers at Avondale were documented as aware of the dangers of occupational asbestos exposure by at least the early 1960s — a period during which thousands of workers continued to handle asbestos-containing materials daily in the shipyard without warning, without protective equipment, and without any dust control measures.
Avondale’s own industrial hygienist documented elevated asbestos fiber counts in confined shipyard spaces during testing conducted in the 1960s. The measurements recorded in these internal documents showed fiber concentrations in enclosed hull sections that exceeded thresholds associated with serious occupational disease risk. This information was not shared with workers. No warnings were posted. No respirators were distributed. No modifications to work practices were implemented. The fiber count data remained internal to management and the safety department while the workforce continued daily exposure to the conditions it documented.
Worker testimony in depositions taken across dozens of Avondale cases painted a consistent picture of deliberate suppression of safety information. Former Avondale workers testified that they were never warned about the risks of asbestos exposure during their employment at the yard. They were never provided respirators or any other form of respiratory protection during insulation work. Workers who raised safety concerns — including concerns about the visible dust generated by cutting and handling insulation products — testified that complaints were discouraged by supervisors and that raising safety issues was seen as a threat to one’s continued employment. This pattern of deliberate concealment, documented across multiple independent depositions, formed a central evidentiary pillar of the intentional act finding that distinguished Avondale litigation from ordinary asbestos employer liability cases.
Finding 4 The Landmark Court Decision — The Intentional Act Doctrine
The Avondale Shipyards asbestos cases produced one of the most consequential employer liability rulings in Louisiana legal history. The pivotal legal question was whether Avondale’s conduct in knowingly exposing workers to asbestos without warning met the threshold of an “intentional act” under Louisiana workers’ compensation law — a finding that, if made, would strip the company of the immunity from civil tort suits that workers’ compensation law ordinarily provides to employers.
Under Louisiana’s Workers’ Compensation Act, La. R.S. 23:1032, an employer is generally immune from tort liability for workplace injuries covered by the workers’ compensation system. Injured workers receive no-fault compensation through the workers’ comp system but cannot sue their employer in civil court for pain and suffering, emotional distress, or other general damages. The intentional act exception to this immunity applies when an employer “deliberately intend[s] the act which caused the injury.” Louisiana courts have interpreted this to include situations where an employer had actual knowledge that a particular condition would cause a worker’s injury and deliberately failed to remedy it.
In a series of cases culminating in Louisiana First Circuit Court of Appeal rulings in the 1990s and 2000s, courts found that Avondale Industries met this standard. The courts found that Avondale management had actual knowledge that asbestos exposure caused serious occupational disease — knowledge documented in the company’s own internal industrial hygiene records — and that the company deliberately chose not to warn workers or provide any protective measures. This deliberate decision, courts found, constituted an intentional act within the meaning of La. R.S. 23:1032’s exception.
The consequence of this ruling was transformative for Avondale workers. Rather than being limited to the scheduled benefits of the workers’ compensation system — modest, capped payments with no recovery for pain and suffering — Avondale workers could bring full civil tort claims seeking compensatory damages for medical expenses, lost wages, pain and suffering, and loss of enjoyment of life, as well as potentially punitive damages. This expansion of available remedies produced substantially larger average recoveries for Avondale workers than would have been available in a conventional workers’ compensation framework, and placed Avondale asbestos cases among the most legally significant employer liability decisions in the Gulf South.
Finding 5 Trust Funds, Successor Liability, and Current Claims
Avondale Shipyards passed through several ownership changes during its operational life. The yard was acquired by Litton Industries in the 1960s, eventually became Avondale Industries Inc. as an independent public company, and was ultimately acquired by Northrop Grumman in 1999. Huntington Ingalls Industries acquired the shipbuilding assets from Northrop Grumman in 2011, including the Avondale yard. The Avondale facility was shut down in 2014.
Each step in this corporate chain carries implications for asbestos liability. Successor liability principles in Louisiana and under federal maritime law mean that acquiring companies generally assume responsibility for the liabilities of the entities they acquire. Huntington Ingalls Industries discloses asbestos litigation liabilities arising from the Avondale operations in its annual SEC filings, confirming that claims continue to be filed and resolved. Asbestos bankruptcy trusts established by predecessor entities associated with Avondale operations also process claims, providing an additional compensation pathway for eligible claimants.
The table below summarizes the principal claim types available to Avondale workers and their families, along with approximate compensation ranges based on historical settlement data and published trust fund criteria. These figures represent ranges observed in resolved claims and should be understood as general guidance; individual claim values depend on disease severity, work history, supporting documentation, and the specific legal strategy employed.
| Claim Type | Trust / Defendant | Approximate Payout Range | Notes |
|---|---|---|---|
| Mesothelioma | Civil tort litigation / asbestos trusts | $150,000 – $1,800,000+ | Louisiana 1-year prescriptive period runs from diagnosis date; intentional act doctrine may significantly increase recovery |
| Asbestosis | Asbestos trust funds | $15,000 – $75,000 | Medical documentation including pulmonary function testing required; severity level affects payout tier |
| Lung Cancer | Civil tort litigation and trust funds | $80,000 – $400,000 | Must demonstrate asbestos as a contributing or substantial cause; smoking history may be contested by defendants |
| Wrongful Death | Civil tort litigation | $200,000 – $2,000,000+ | 1-year prescriptive period runs from date of death in Louisiana; intentional act finding may support punitive damage claims |

Frequently Asked Questions
Avondale Shipyards became a landmark asbestos case because Louisiana courts found that its management committed an “intentional act” under Louisiana workers’ compensation law by knowingly concealing asbestos hazards from workers. Under Louisiana’s standard workers’ compensation rules, injured workers are generally limited to no-fault benefits and cannot sue their employer in civil court. The intentional act exception strips away that immunity when an employer deliberately exposes workers to a known danger without warning. Courts found that Avondale’s own industrial hygienist documented dangerous asbestos fiber counts and that management chose not to inform workers, distribute respirators, or implement protective measures — a deliberate decision that met the intentional act threshold and exposed the company to full tort liability, including pain and suffering and punitive damages.
Direct Avondale Shipyards employees who worked at the Westwego facility during any period from 1938 through 2002 and have been diagnosed with mesothelioma, asbestosis, or an asbestos-related lung cancer may be eligible to file claims. Independent contractors and subcontractors who performed work on-site — including pipefitters, insulators, and boilermakers employed by third-party contractors — may also have viable claims against Avondale and their direct employers. Family members who developed asbestos-related disease through secondary take-home exposure, caused by workers carrying asbestos fibers home on their clothes and skin, may also be eligible for compensation.
Louisiana uses a 1-year prescriptive period for personal injury claims, including asbestos-related disease. The clock begins running on the date of diagnosis — not the date of exposure, which may have occurred decades earlier. For wrongful death claims brought by family members after a worker’s death, the 1-year period runs from the date of death. Louisiana’s prescriptive period is shorter than most states’, making it critical to contact an asbestos attorney immediately after any diagnosis of mesothelioma, asbestosis, or asbestos-related lung cancer. Courts have recognized a discovery rule in limited circumstances, but relying on it is legally risky and should never substitute for prompt action.
The products most heavily implicated in Avondale asbestos exposure through litigation records are Unibestos pipe covering (Pittsburgh Corning, containing 85% chrysotile and amosite), Kaylo pipe covering (Owens-Illinois, containing amosite), and Thermobestos (Philip Carey). Sprayed-on asbestos fireproofing applied to hull sections — associated with W.R. Grace & Company and predecessor formulations — also generated extremely high airborne fiber concentrations because workers applied the material by spraying in enclosed spaces. Block insulation used around boilers and steam systems was an additional major source of exposure for boilermakers and nearby trades. Purchase orders confirming the use of these specific products at Avondale were produced in litigation and are part of the public court record.
Yes. Family members can file claims through two distinct avenues. Spouses, children, and others living with Avondale workers may have been exposed to asbestos fibers carried home on work clothing, hair, and skin — a mechanism known as secondary or take-home exposure that has produced mesothelioma diagnoses in people who never set foot in the shipyard. Those individuals may bring their own personal injury claims. If an Avondale worker has died from mesothelioma or another asbestos-related disease, surviving family members may bring a wrongful death claim under Louisiana law. Louisiana’s 1-year prescriptive period for wrongful death runs from the date of death, making it essential to consult an asbestos attorney promptly.
Avondale Shipyards ceased operations in 2014 when Huntington Ingalls Industries shut down the Westwego facility due to declining Navy contract work. The closure did not extinguish legal liability for historic asbestos exposure. Huntington Ingalls Industries assumed successor liability through the acquisition chain — from Avondale Industries through Northrop Grumman to Huntington Ingalls — and discloses ongoing asbestos litigation in its annual SEC filings. Asbestos trust funds established by predecessor entities continue to process claims from eligible workers. An asbestos attorney can identify all responsible parties in the corporate lineage for a given worker’s exposure period, ensuring no avenue of recovery is overlooked.
Compensation amounts vary widely based on disease severity, work history, and the legal route taken. Mesothelioma claims have resulted in settlements and verdicts ranging from approximately $150,000 to over $1.8 million, with some outlier verdicts substantially higher. The landmark intentional act finding in Louisiana courts meaningfully expands the categories of damages available to Avondale workers compared to most industrial asbestos cases, because it allows claims for pain and suffering, emotional distress, and potentially punitive damages that would otherwise be barred by workers’ compensation exclusivity. Asbestosis claims through trust funds have generally ranged from $15,000 to $75,000 depending on documented severity and functional impairment.
Employment at Avondale can be established through multiple types of records. Social Security earnings history — obtainable directly from the Social Security Administration — will show wages reported by Avondale Industries for the years you worked there. Former union members can request records from relevant union locals, particularly Boilermakers Local 37, Pipefitters Local 60, or Painters and Allied Trades locals active in the New Orleans area during your employment period. Co-worker affidavits from former colleagues who can confirm your presence at the yard during a specific period are also routinely accepted by courts and trust fund administrators. An asbestos attorney will gather these records on your behalf — you do not need any documentation in hand before your first free consultation.
