Jones Act Seaman Status and Implications with LHWCA

A deckhand on your towboat and a rigger on your dock can be injured on the same day, doing work that looks broadly similar, and be covered by two entirely different legal systems with different insurance policies behind them. Get the classification wrong and you have an injured employee, a claim your policy does not respond to, and a lawsuit your workers' compensation coverage was never designed to defend.

For Gulf Coast operators, this is not an abstract legal question. Harbor towing companies, inland barge lines, OSV operators, terminal operators, and shipyards routinely employ workers on both sides of the line, and some workers move back and forth across it depending on the assignment. The Fifth Circuit, which covers Texas, Louisiana, and Mississippi, hears more of these cases than any other circuit in the country, and it has tightened the test significantly in recent years.

This article walks through the three systems, how courts decide which one applies, what changed in 2021, and what an operator should actually do about it.

Three Systems, Mutually Exclusive

American law provides three separate remedies for an injured worker, and a given worker falls under exactly one of them.

State workers' compensation covers land-based employees. It is a no-fault system providing medical benefits and a portion of lost wages according to a state schedule, and it is generally the employee's exclusive remedy against the employer. Louisiana, Texas, Mississippi, and Alabama each run their own program with their own benefit levels.

The Longshore and Harbor Workers' Compensation Act, codified at 33 U.S.C. 901 and following, covers maritime workers who are not crew. Longshoremen, stevedores, ship repairers, shipbuilders, shipbreakers, and harbor workers fall here. Like state comp it is no-fault and exclusive, but benefits run substantially higher than most state schedules. Operators and brokers usually refer to the coverage as USL&H.

The Jones Act, 46 U.S.C. 30104, covers seamen. This one is fundamentally different from the other two. It is not a compensation scheme at all but a negligence cause of action, giving the injured seaman the right to sue the employer for damages before a jury. It sits alongside the general maritime law remedies of unseaworthiness and maintenance and cure. There is no benefit schedule and no cap. A seaman with a serious injury and a sympathetic jury can recover figures that no comp system would produce.

That difference is the reason classification matters so much. Moving a worker from USL&H to Jones Act does not adjust a benefit level. It converts a scheduled claim into open-ended litigation exposure.

How Courts Decide: The Seaman Test

The Supreme Court set the framework in Chandris, Inc. v. Latsis, 515 U.S. 347 (1995). A worker qualifies as a seaman if two things are true:

First, the worker's duties must contribute to the function of the vessel or to the accomplishment of its mission. This element is broad. It comes from McDermott International, Inc. v. Wilander, 498 U.S. 337 (1991), which rejected the older rule that a seaman had to aid in navigation. A cook, an engineer, a cleaner, or a construction worker can satisfy it. If the vessel is doing a job and the worker is part of doing that job, this prong is met.

Second, the worker must have a connection to a vessel in navigation, or to an identifiable group of vessels, that is substantial in both duration and nature. This is where cases are actually decided, and the Court was explicit that both components must be satisfied rather than either one.

On duration, the Court endorsed the Fifth Circuit's existing practice. A worker who spends less than about 30 percent of his time in the service of a vessel in navigation should not qualify as a seaman. The Court described this as a rule of thumb established by years of experience rather than a rigid line, and departure from it can be justified in appropriate cases.

Two practical points about the 30 percent figure. It is measured against the worker's employment with that employer overall rather than against the particular assignment during which the injury occurred. And a worker who receives a new assignment with materially different essential duties is entitled to have the assessment made on the basis of the new position rather than the old one.

The Court was also clear that seaman status does not attach simply because a worker happened to be necessary to the vessel's mission at the moment of injury. The inquiry is about the enduring relationship, not the snapshot.

What Changed in 2021

If your understanding of this area predates 2021, it is out of date, and the change came from the Fifth Circuit, which means it applies directly to Gulf operators.

In Sanchez v. Smart Fabricators of Texas, L.L.C., 997 F.3d 564 (5th Cir. 2021) (en banc), the court reconsidered how the nature element works. Gilbert Sanchez was a welder-fitter employed by a land-based fabricator. He worked 61 of his 67 days of employment aboard two jack-up drilling rigs. On the rig where he was injured, the deck was jacked level with an adjacent dock, separated by a gangplank, and he walked ashore and commuted home every evening.

On the duration numbers alone, Sanchez looks like a seaman comfortably. A three-judge panel had in fact found that he was.

Sitting en banc, the Fifth Circuit unanimously held that he was not. His work was a discrete, transient job, comparable to what longshoremen do when a vessel calls in port. Relying on Harbor Tug & Barge Co. v. Papai, 520 U.S. 548 (1997), the court held that workers with only a transitory or sporadic connection to a vessel do not qualify, and that Sanchez would have no further connection to the rig once his job was finished. He failed the nature element regardless of the time he had logged.

The court added three questions that must now be asked in any Fifth Circuit seaman analysis:

(1) Does the worker owe allegiance to the vessel rather than simply to a shoreside employer? (2) Is the work sea-based, or does it involve seagoing activity? (3) Is the worker's assignment limited to performing discrete tasks after which the connection to the vessel ends, or does the assignment include sailing with the vessel from port to port or location to location?

The court also formally overruled Naquin v. Elevating Boats, L.L.C., 744 F.3d 927 (5th Cir. 2014) and the line of cases following it, holding that they had misread the test. And it settled a point that had generated years of argument. Incidental exposure to the perils of the sea does not by itself satisfy the nature element.

The practical effect is that time aboard is no longer close to sufficient. A worker can spend nearly all of his employment on a vessel and still be a longshoreman if his relationship to that vessel is task-based rather than crew-based.

How LHWCA Coverage Works

If a worker is not a seaman, the next question is whether USL&H applies. The Act imposes two requirements and both must be met.

Status, under 33 U.S.C. 902(3), asks whether the worker was engaged in maritime employment. The statute names longshoremen and others engaged in longshoring operations, and harbor workers including ship repairers, shipbuilders, and shipbreakers. Courts have extended it to less obvious roles, including workers operating or maintaining the equipment that moves containers away from ships.

Situs, under 33 U.S.C. 903(a), asks where the injury occurred. There are three routes to satisfying it. An injury upon the navigable waters of the United States. An injury on an enumerated site, meaning an adjoining pier, wharf, dry dock, terminal, building way, or marine railway. Or an injury on an other adjoining area customarily used by an employer in loading, unloading, repairing, dismantling, or building a vessel. Where a worker is injured on actual navigable waters, the situs requirement is independently satisfied.

The Act also carries a list of exclusions that catch operators out. Section 902(3)(G) excludes masters and members of a crew of any vessel, which is the provision that keeps the Jones Act and USL&H mutually exclusive. Other exclusions cover clerical, secretarial, security, and data processing employees, marina employees not engaged in construction or expansion of the marina, certain vendors' employees temporarily on maritime premises, and workers building recreational vessels under 65 feet or repairing recreational vessels. Most of these exclusions apply only if the worker is covered by a state workers' compensation program, which is a detail worth confirming rather than assuming.

Two extensions matter for Gulf operators. The Outer Continental Shelf Lands Act extends LHWCA coverage to workers on offshore oil and gas operations on the OCS. The Defense Base Act extends it to certain overseas government contract work.

Where This Bites in Practice

A few patterns generate most of the real-world classification problems.

The worker who does both. A harbor towing company employs someone who works on the boats some weeks and on the dock others. His classification depends on the overall proportions and on the character of the vessel work, and it can shift if his role changes. If your policies were bought on the assumption that he sits in one category, a claim will find the assumption.

The repair and maintenance worker. After Sanchez, a worker who boards vessels to perform discrete repair jobs and leaves when the job is done is very likely a longshoreman even if he is aboard vessels constantly. Shipyards, mobile repair outfits, and terminal maintenance crews should look hard at this.

The vessel that is barely a vessel. Seaman status requires a connection to a vessel in navigation. Whether a jack-up rig, a spudded barge, a permanently moored structure, or a dredge qualifies is itself litigated, and the answer drives everything downstream.

The tug and barge crew. Conversely, crew who sail with a towboat from port to port, live aboard, and take their orders from the vessel are seamen under any version of the test. The Fifth Circuit in Sanchez explicitly used the crew of an inland tug working a calm river as an example of workers who are sea-based despite facing no ocean perils. Inland operators sometimes assume the Jones Act is a blue-water statute. It is not.

The multi-employer dock. Terminal operators, stevedores, contractors, and vessel crew all working the same berth means a single incident can produce claims under all three systems simultaneously, plus liability claims between the employers.

What Operators Should Do:

Classify by function, not by job title. Deckhand and dock worker are payroll categories. The legal test looks at what the person actually does, how much of the time, and what relationship they hold to a vessel. Audit against the real work.

Carry coverage on both sides where workers straddle the line. The Jones Act and LHWCA are mutually exclusive remedies with seaman status as the deciding factor, and after Sanchez, industry participants may benefit from broader policies covering both Jones Act and LHWCA exposure rather than assuming a clean split. For an operator with any classification ambiguity, a program that responds either way is not redundant coverage. It is the only structure that does not leave a gap.

Understand what maritime employers liability does. MEL is the coverage that responds to Jones Act and general maritime law claims by crew. It is not USL&H and it is not state comp. An operator with crew and no MEL is uninsured for the largest single exposure in the business.

Verify your USL&H is actually in force. USL&H is typically added by endorsement to a workers' compensation policy rather than bought standalone. It is also frequently assumed rather than confirmed. Check the declarations page.

Reassess when roles change. Chandris makes clear that a new assignment with different essential duties resets the analysis. Promotions, reassignments, and shifts between shoreside and vessel work all warrant a fresh look.

Do not rely on what the employee is called in the contract. Courts decide status on the facts. A contract that designates someone a seaman or a longshoreman does not control the outcome, and it will not help you when the claim arrives.

The Bottom Line

The classification question is decided after the injury, by a court, applying a fact-intensive test to circumstances you no longer control. The only thing you control is whether your insurance program is built to respond whichever way that determination goes.

For a Gulf Coast operator with vessels and shoreside personnel, that means state comp, USL&H, and maritime employers liability properly coordinated, with the overlaps understood and the gaps closed deliberately. It is not an expensive structure to build correctly. It is an extremely expensive one to discover you built wrong.
