1. What is the LHWCA?
The Longshore and Harbor Workers Compensation Act (33 U.S.C. §§ 901 to 950) is a 1927 federal workers compensation system that covers maritime workers who are not seamen, including longshoremen, harbor workers, shipbuilders, ship repairers, and (through extensions) offshore platform workers and overseas defense contractors.
The LHWCA is the federal cousin of state workers compensation. It came about because, before 1927, longshoremen and harbor workers fell into a legal gap: they were not seamen (so the Jones Act did not cover them) but they worked over navigable water (so state workers comp could not cover them either). Congress wrote the LHWCA to fill that gap.
It is workers compensation, which means it is no-fault. You do not have to prove your employer did anything wrong. If you got hurt at work, you are owed benefits. The trade-off is that, like other workers comp systems, you generally cannot sue your employer directly. But unlike state systems, you may still sue third parties (we will get to that, it is huge).
Bottom line: LHWCA is federal workers comp for maritime workers who are not seamen. It pays more than state systems, covers more medical care, and may unlock a separate negligence lawsuit against vessel owners.
The Act applies to "the disability or death of an employee... if the disability or death results from an injury occurring upon the navigable waters of the United States (including any adjacent pier, wharf, dry dock, terminal, building way, marine railway, or other adjoining area customarily used by an employer in loading, unloading, repairing, dismantling, or building a vessel)."
33 U.S.C. § 903(a): Coverage
Where did this law come from?
Until the 1920s, longshoremen and harbor workers lived in a legal no-mans-land. The Supreme Court had ruled in Southern Pacific Co. v. Jensen (1917) that state workers comp could not constitutionally cover maritime workers, because admiralty was a federal matter. Congress tried to fix it in 1922 by letting states extend their workers comp to maritime workers, but the Supreme Court struck that down too.
So in 1927 Congress wrote the LHWCA. Federal workers comp for federal maritime workers. It has been amended several times since (1972 amendments expanded coverage; 1984 amendments added contemporary procedures), but the core idea has not changed: no-fault benefits for maritime workers who are not seamen.
How LHWCA fits with the Jones Act
The Jones Act and the LHWCA are mutually exclusive. You are either a seaman (Jones Act) or you are a longshore-type worker (LHWCA). You cannot be both for the same job. The distinction comes from the Chandris v. Latsis Supreme Court test from 1995, which asks whether you contribute to a vessel mission and spend a substantial portion of your work time in service of that vessel in operation.
If you spend most of your time tied to a particular vessel and you are part of its crew, you are probably a seaman. If you work at a port or shipyard and you go from vessel to vessel as cargo or repair work brings them in, you are probably an LHWCA worker. The line is not always clean, and lawyers fight over it all the time. Picking the wrong framework can cost you hundreds of thousands of dollars.
If you are crew on a vessel, think Jones Act. If you work at a port, on a dock, in a shipyard, or on an offshore platform, think LHWCA. The legal test is the Chandris seaman test. A specialty lawyer figures out which framework actually fits your case, because picking wrong means leaving real money on the table.
2. Who qualifies (the status and situs tests)
You qualify for LHWCA coverage if you pass two tests: the status test (you are a maritime worker engaged in maritime employment) and the situs test (you got injured on or near navigable waters, including adjacent piers, wharves, terminals, and shipyards).
This two-part test is the gateway to everything. If you do not pass both, you are not covered by the LHWCA, period. Most denied claims come down to one of these tests, which is why a specialty lawyer matters from day one.
The status test: are you the right kind of worker?
The status test asks whether you are an "employee" within the meaning of the Act. 33 U.S.C. § 902(3) defines that as "any person engaged in maritime employment, including any longshoreman or other person engaged in longshoring operations, and any harborworker including a ship repairman, shipbuilder, and ship-breaker."
That captures most of the obvious workers:
- Longshoremen who load and unload vessels at ports
- Stevedores who oversee or perform longshoring operations
- Ship repairers in dry docks and on the water
- Shipbuilders at yards like Newport News, Pascagoula, Bath Iron Works
- Ship-breakers who dismantle decommissioned vessels
- Harborworkers generally engaged in maritime labor
It does not cover certain categories: clerical, secretarial, security, or data-processing workers (unless they are actively engaged in maritime operations); marina workers servicing recreational boats; workers covered by another federal program; and (the big one) seamen, who are Jones Act, not LHWCA.
A longshoreman's status applies even if they are only intermittently performing covered work. The Supreme Court rejected the idea that you have to be "actually engaged" in maritime work at the precise moment of injury.

The situs test: were you in the right place?
The situs test asks where the injury occurred. 33 U.S.C. § 903(a) requires injury "upon the navigable waters of the United States (including any adjacent pier, wharf, dry dock, terminal, building way, marine railway, or other adjoining area customarily used by an employer in loading, unloading, repairing, dismantling, or building a vessel)."
Plain English: if you got hurt on the water itself, you pass situs. If you got hurt on a pier, wharf, dry dock, terminal, or any adjoining maritime area where vessels are loaded, unloaded, built, or repaired, you also pass situs. The "adjoining area" language is what got expanded in the 1972 amendments to give longshoremen meaningful coverage on the dock side of things.
Example scenario
A longshoreman is unloading containers on a pier at the Port of Houston. He slips on hydraulic fluid that leaked from a crane and breaks his hip. Status: He is a longshoreman engaged in maritime employment, so yes. Situs: He is on a pier customarily used for loading and unloading vessels, so yes. He is covered.
Example scenario
A clerical worker at a port company falls down stairs at the corporate office, which is two miles inland from the dock. Status: Clerical work is excluded from coverage. Situs: The office is not adjacent to navigable waters. Not covered by LHWCA. She would file state workers compensation.
The hard cases
Most LHWCA fights happen at the edges of these two tests. A truck driver who hauls cargo into and out of a port may or may not have status. A welder who works at a shipyard but on a non-maritime structure may or may not have situs. A worker who got hurt at a parking lot adjacent to a marine terminal may or may not pass situs. Courts decide these on the facts. A specialty lawyer has seen them and knows how to frame them.
Bottom line: You need both status (you are a maritime worker) and situs (you were hurt on navigable waters or in an adjoining maritime area). Borderline cases get decided by Administrative Law Judges and federal courts, and specialty matters enormously when the question is close.
3. The three extensions that widen the net
The base LHWCA covers longshoremen, harbor workers, ship repairers, shipbuilders, and ship-breakers. But Congress also extended LHWCA-style benefits to three additional groups through separate statutes. Each one matters because it brings federal-level workers compensation to workers who would otherwise be stuck with weaker state systems or no coverage at all.
Offshore platforms
OCSLA
Outer Continental Shelf Lands Act extends LHWCA benefits to workers on fixed offshore platforms and drilling rigs in federal waters. Huge for Gulf of Mexico oil and gas workers.
Overseas contractors
Defense Base Act
DBA covers civilian contractors working for the U.S. military or government overseas. Iraq, Afghanistan, Kuwait, all military bases worldwide. Benefits are LHWCA-style.
Federal employees
NAFI Act
Non-Appropriated Fund Instrumentalities Act covers civilian employees of post exchanges, base commissaries, and similar federal entities not paid from appropriated funds.
OCSLA: offshore platform workers
The Outer Continental Shelf Lands Act (43 U.S.C. § 1331 et seq.) extends LHWCA coverage to workers on fixed structures (platforms, drilling rigs, production facilities) on the Outer Continental Shelf, which is generally federal waters beyond state jurisdiction. For most of the Gulf of Mexico oil and gas industry, OCSLA is the framework.
The big catch: OCSLA applies to fixed platforms. Floating drilling rigs and drillships are vessels, and people working on them may be Jones Act seamen instead. The distinction was sharpened in Stewart v. Dutra Construction (2005), which held that even a dredge with limited mobility could be a "vessel" for Jones Act purposes. So a roustabout on a jack-up rig could be OCSLA or Jones Act depending on the precise nature of the rig and his connection to it. Specialty lawyers fight over these distinctions because the recovery math is very different.
Defense Base Act: civilian contractors abroad
The Defense Base Act (42 U.S.C. §§ 1651 to 1654) extends LHWCA benefits to civilian contractors working for the U.S. government overseas, including on military bases, embassies, and humanitarian operations. The DBA covered tens of thousands of contractors injured in Iraq and Afghanistan. It still covers contractors at bases worldwide.
DBA cases have some unique features: benefits are paid in U.S. dollars regardless of where the worker was based, the maximum benefit rate is the same as LHWCA, and the case is generally adjudicated in the U.S. through the OWCP. But DBA cases often involve unique issues: war zone injuries, evacuation logistics, mental health (especially PTSD), and complex causation. Most workers comp lawyers have never handled a DBA case. A specialty DBA practice is a real thing.
NAFI Act: certain federal employees
The Non-Appropriated Fund Instrumentalities Act (5 U.S.C. § 8171 et seq.) covers civilian employees of "non-appropriated fund instrumentalities" of the U.S. government. That includes places like post exchanges (PXs), base commissaries, officers clubs, and similar entities that operate on federal property but are not funded through Congressional appropriations. These workers get LHWCA-style benefits if they are injured on the job.
Picking the right framework
If you got hurt on a fixed offshore platform, you might be covered by OCSLA. If you got hurt on a floating drilling rig or drillship, you might be a Jones Act seaman instead. If you got hurt working on a military base overseas as a civilian contractor, DBA applies. Picking the wrong framework means leaving the right benefits and rights on the table. A specialty lawyer figures out which one fits your case.
4. What kinds of injuries qualify?
Any work-related injury that happens within the LHWCA status and situs framework qualifies. Workers comp does not require negligence. If you got hurt doing your job, you are covered. Here are the most common injury patterns we see across LHWCA, OCSLA, and DBA cases.
Crush injuries
Containers, cargo, equipment, vehicles. Crush injuries on docks and in cargo holds are common and often catastrophic.
Slip and fall
Wet decks, hydraulic spills, ice, missing non-skid. Falls cause everything from sprains to traumatic brain injuries.
Lifting/strain injuries
Back, neck, shoulder, knee. Repetitive lifting and awkward postures cause both acute and cumulative trauma injuries.
Falls from height
Falls from cranes, scaffolding, platforms, or rigging. Often catastrophic and may also involve OSHA violations.
Equipment failure
Cranes, forklifts, winches, hoists. Equipment failures often open a Section 905(b) claim against the vessel owner.
Exposure injuries
Chemicals, asbestos, benzene, diesel exhaust, fumes. Often cumulative; latent injuries can surface years later.
Welding injuries
Burns, eye damage, fume inhalation, electrocution. Shipyard welders face a unique injury profile.
Confined-space injuries
Asphyxiation, toxic exposure, drowning, entrapment. Tank-cleaning and hold work are particularly dangerous.
Hearing loss
Cumulative noise exposure in ports and shipyards is a major source of LHWCA hearing-loss claims, often surfacing on retirement.
Occupational diseases and latent injuries
The LHWCA covers occupational diseases as well as traumatic injuries. The big one historically has been asbestos exposure for shipyard workers (the Navy yard generation in particular). Mesothelioma, asbestosis, lung cancer, and other diseases that develop decades after exposure are all covered if they arose out of and in the course of employment. Hearing loss from chronic noise exposure is another common occupational claim. PTSD and other mental health injuries qualify if they are tied to a work event or pattern.
The notice and filing rules work differently for latent injuries (we will cover deadlines in Section 10). The general rule is that the clock starts when you knew, or should have known, that your injury was work-related, not when the exposure happened. That helps workers whose cancer or hearing loss does not surface for decades.
If you work in a covered maritime job and you got hurt, the question is not whether you have a case. You have a case. The question is whether you also have a Section 905(b) negligence claim against a vessel owner on top of your LHWCA benefits. That is where a specialty lawyer earns their fee.
