Executive Summary

The Longshore and Harbor Workers' Compensation Act (LHWCA), codified at 33 U.S.C. § 901 et seq., is the federal workers' compensation program covering most private-sector maritime employees — including shipyard workers, longshoremen, ship repairers, and harbor construction workers — who are injured or who develop occupational disease on the navigable waters of the United States or in adjoining areas such as piers, dry docks, and terminals. Enacted in 1927 and administered by the U.S. Department of Labor's Office of Workers' Compensation Programs, the statute is a primary compensation pathway for the maritime and shipyard workforce that suffered heavy occupational asbestos exposure through the mid-twentieth century. Because asbestos diseases such as mesothelioma surface decades after exposure, the Act's occupational-disease provisions — and its interaction with the Jones Act, asbestos trust funds, and third-party litigation — are central to how these claims are resolved.

History of the Act

Before 1927, maritime workers injured on the navigable waters of the United States occupied a legal gap: the U.S. Supreme Court had held that state workers' compensation laws could not constitutionally reach injuries occurring on navigable waters, yet no federal compensation program existed to fill the space. Congress responded with the Longshoremen's and Harbor Workers' Compensation Act, enacted as the Act of March 4, 1927 (ch. 509, 44 Stat. 1424), providing compensation and medical benefits to maritime employees — other than the master or crew of a vessel — injured while working on the navigable waters of the United States.

The original 1927 statute extended only to the "water's edge." The 1972 amendments (Pub. L. 92–576) reshaped the program in three important ways: they replaced the strict water's-edge boundary with a two-part "status and situs" test that moved coverage landward to "adjoining areas" customarily used for loading, unloading, repairing, or building vessels; they substantially raised benefit levels so that LHWCA benefits generally exceed those available under state compensation laws; and they restructured the relationship between injured workers and vessel owners by eliminating the "unseaworthiness" remedy against vessels while preserving a negligence action. The 1984 amendments (Pub. L. 98–426) refined coverage and benefit provisions and changed the program's formal name from "Longshoremen's" to "Longshore" and Harbor Workers' Compensation Act, the title in use today.

Coverage: Who Qualifies?

LHWCA coverage turns on a combined status and situs test. The status requirement asks whether the worker is engaged in "maritime employment"; the situs requirement asks whether the injury occurred on a covered location. The statute defines the covered location broadly. Under 33 U.S.C. § 902(4), coverage reaches employment "upon the navigable waters of the United States (including any adjoining pier, wharf, dry dock, terminal, building way, marine railway, or other adjoining area customarily used by an employer in loading, unloading, repairing, or building a vessel)." Section 903 confirms that compensation is payable "only if the disability or death results from an injury occurring upon the navigable waters of the United States."

Covered workers typically include longshoremen, stevedores, ship repairers, shipbuilders, and harbor construction workers. The statute expressly excludes several groups:

• Seamen. Section 902(3) provides that the term "employee" "does not include … a master or member of a crew of any vessel." Seamen instead pursue remedies under the Jones Act (discussed below).
• Federal employees. Officers and employees of the United States are excluded and are instead covered by the Federal Employees' Compensation Act (FECA).
• Intoxication and willful injury. No compensation is payable where the injury was occasioned solely by the worker's intoxication or by a willful intention to injure or kill.
• Certain small-vessel and recreational workers, subject to statutory exceptions tied to navigable waters, federal subsidy, or the availability of state coverage.

What Benefits Does the LHWCA Provide?

The Act provides four principal categories of benefits, anchored in 33 U.S.C. §§ 908–910.

• Disability compensation. For permanent total disability and for temporary total disability, the statute pays "66⅔ per centum of the average weekly wages" during the continuance of the disability. The Act also provides scheduled awards for permanent partial disability and benefits for temporary partial disability.
• Medical treatment. The Act covers the cost of medical, surgical, and hospital treatment and other reasonable and necessary care for the work-related condition.
• Death benefits. Where a covered injury or occupational disease results in death, surviving dependents are entitled to death benefits and funeral expenses under 33 U.S.C. § 909.
• Vocational rehabilitation. The program provides vocational rehabilitation services to help disabled workers return to suitable employment.

Disability compensation is bounded by a national maximum and minimum rate that the Department of Labor adjusts each October 1 under Section 10(f) of the Act. For the period beginning October 1, 2025, the National Average Weekly Wage (NAWW) is $1,041.35; the maximum weekly compensation rate (200% of the NAWW) is $2,082.70, and the minimum rate (50% of the NAWW) is $520.68. These figures reflect a 4.18% Section 10(f) increase over the prior period.

Filing and Administration

The LHWCA is administered by the U.S. Department of Labor through the OWCP Division of Longshore and Harbor Workers' Compensation, which operates district offices that process claims and resolve disputes. An injured worker generally files a claim with the OWCP district office; contested claims may be referred to a Department of Labor administrative law judge, with further review available before the Benefits Review Board and, ultimately, the federal courts of appeals.

Time limits are governed by 33 U.S.C. § 913. The general rule bars a claim "unless a claim therefore is filed within one year after the injury or death." For occupational disease, however, the statute extends the window: a claim "for death or disability due to an occupational disease which does not immediately result in such death or disability" is timely if filed "within two years after the employee or claimant becomes aware … of the relationship between the employment, the disease, and the death or disability," or within one year of the last compensation payment, whichever is later. This awareness-based two-year rule is what makes the LHWCA workable for latency-period diseases such as mesothelioma, where the diagnosis can arrive forty or more years after the exposure.

How Does the LHWCA Apply to Asbestos Disease?

Asbestos litigation tests the LHWCA's occupational-disease machinery more than almost any other condition, because shipyards and ports were among the most heavily asbestos-exposed workplaces of the twentieth century and because the resulting diseases have exceptionally long latency.

Latency and the filing clock. Because § 913's two-year clock for occupational disease runs from the worker's awareness of the connection between employment and disease — not from the date of exposure — a worker exposed in a 1960s shipyard who is diagnosed with mesothelioma decades later can still file a timely LHWCA claim.

The "last responsible employer" doctrine. Where a worker was exposed to asbestos across several maritime employers, the LHWCA does not apportion liability among them. Under the rule established in Travelers Insurance Co. v. Cardillo, 225 F.2d 137 (2d Cir.), cert. denied, 350 U.S. 913 (1955), the last maritime employer that exposed the worker to injurious stimuli before the worker became aware of the disease is liable for the full award. An actual causal contribution by that final exposure is not required; potential to cause the disease is enough. This rule simplifies recovery for workers but makes employer and insurer identification a central battleground in shipyard asbestos claims.

The dual pathway against vessel owners. Although LHWCA benefits are the exclusive remedy against a worker's employer under 33 U.S.C. § 905(a), Section 905(b) preserves a separate negligence action against a vessel as a third party. A longshore or shipyard worker injured by the negligence of a vessel may therefore collect LHWCA compensation from the employer and, in addition, bring a § 905(b) negligence suit against the vessel owner — a combination unavailable to most land-based industrial workers.

Concurrent claims. An LHWCA claim does not foreclose other asbestos recovery. Covered workers frequently pursue asbestos trust fund claims against bankrupt manufacturers and product-liability litigation against asbestos suppliers in parallel with their LHWCA benefits, subject to statutory offset and lien rules.

How Is the LHWCA Different from the Jones Act?

The single most consequential distinction in maritime asbestos claims is between the LHWCA and the Jones Act, because the two statutes cover mutually exclusive populations and offer different remedies.

The LHWCA covers land-side and harbor maritime workers — those working on docks, in shipyards, and in adjoining areas. The Jones Act (46 U.S.C. § 30104) covers seamen — the masters and crew members of a vessel in navigation, who are expressly excluded from the LHWCA's definition of "employee." The two regimes differ in remedy: the LHWCA is a no-fault compensation system, while the Jones Act allows a seaman to bring a negligence lawsuit against the employer, with the prospect of broader damages including pain and suffering.

Whether a given worker is a "seaman" (Jones Act) or a covered "employee" (LHWCA) is decided by the worker's status at the time of injury. In Chandris, Inc. v. Latsis, 515 U.S. 347 (1995), the Supreme Court held that seaman status requires an employment-related connection to a vessel in navigation that is "substantial in terms of both its duration and its nature," such that the worker is "part of the vessel's crew" rather than a land-based employee who happens to be aboard. A worker who fails the seaman-status test typically falls within LHWCA coverage instead. Because the statutes are mutually exclusive, correctly classifying the worker is the threshold question in any maritime asbestos claim.

Related Statutes

Several statutes extend or parallel the LHWCA:

• Defense Base Act (42 U.S.C. § 1651). The DBA extends LHWCA coverage to civilian employees of U.S. government contractors working overseas, applying the LHWCA's benefit framework to that workforce.
• Outer Continental Shelf Lands Act (43 U.S.C. § 1333). The OCSLA extends LHWCA coverage to workers engaged in resource-extraction operations on the Outer Continental Shelf.
• Veterans' benefits. The LHWCA and the U.S. Department of Veterans Affairs disability system are separate programs. A veteran who served aboard ship and was later employed in a covered civilian maritime occupation may have both a VA disability claim tied to military service and an LHWCA claim tied to civilian shipyard work; the two are evaluated independently and should not be conflated.

Frequently Asked Questions

Who qualifies for LHWCA benefits?

Most private-sector maritime employees injured on the navigable waters of the United States or in adjoining areas qualify — longshoremen, stevedores, ship repairers, shipbuilders, and harbor construction workers. The statute excludes the master and crew of a vessel (seamen), federal employees, and certain small-vessel and recreational workers.

How is the LHWCA different from the Jones Act?

The LHWCA covers land-side and harbor maritime workers under a no-fault compensation system. The Jones Act (46 U.S.C. § 30104) covers seamen — crew members of a vessel in navigation — and allows a negligence lawsuit against the employer. The two are mutually exclusive; the worker's status at the time of injury, under the test in Chandris, Inc. v. Latsis, determines which applies.

What is the deadline to file an asbestos claim under the LHWCA?

For occupational disease that does not immediately cause disability or death, a claim is timely if filed within two years after the worker becomes aware of the relationship between the employment and the disease (or within one year of the last compensation payment, whichever is later). Because the clock runs from awareness rather than exposure, latency-period diseases such as mesothelioma remain claimable decades after exposure.

What benefits does the LHWCA pay?

Disability compensation at two-thirds (66⅔%) of average weekly wages, subject to a national maximum and minimum; full medical treatment for the work-related condition; death benefits and funeral expenses for surviving dependents; and vocational rehabilitation. For the period beginning October 1, 2025, the maximum weekly rate is $2,082.70 and the minimum is $520.68.

Can my family file a death benefit claim?

Yes. Where a covered injury or occupational disease results in death, surviving dependents are entitled to death benefits and funeral expenses under 33 U.S.C. § 909, filed through the OWCP district office.

Can I file an LHWCA claim and an asbestos trust fund claim at the same time?

Yes. An LHWCA claim against a covered employer does not foreclose claims against asbestos trust funds or product-liability suits against asbestos suppliers. These run in parallel, subject to the statute's offset and lien rules.

If a vessel's negligence injured me, can I sue the vessel owner?

Yes. While LHWCA benefits are the exclusive remedy against your employer, 33 U.S.C. § 905(b) preserves a negligence action against a vessel as a third party. A covered worker can collect LHWCA compensation and separately sue a negligent vessel owner.
