Basics of Jones Act and Maritime Rights for Injured Workers

For oilfield and offshore workers in Louisiana, the Jones Act is the most powerful legal tool available for recovering full compensation after a serious work-related injury. It is also one of the most frequently misunderstood. Many injured offshore workers are told by employers or adjusters that workers' compensation is their only option — or that they need to decide quickly between accepting a settlement and pursuing litigation. Understanding the Jones Act, general maritime law unseaworthiness, and the maintenance and cure obligation — and how they interact with each other and with third-party claims — is essential for any injured seaman in Calcasieu Parish or on the Louisiana Gulf Coast.

What Is the Jones Act?

The Jones Act, codified at 46 U.S.C. § 30104, is a federal statute enacted in 1920 that gives qualified seamen the right to maintain a negligence lawsuit against their employer for work-related injuries. Before the Jones Act, seamen's only remedy was the limited common law right to wages and maintenance — the Jones Act created the right to sue for negligence and opened access to full tort damages.

The Jones Act applies to injuries sustained in the course of the seaman's employment — including injuries that occur aboard the vessel, during service of the vessel, and (in some circumstances) while traveling to or from the vessel. The employer's duty of care under the Jones Act is relatively slight — the employer is liable for even the slightest negligence that contributes to the seaman's injury. This is a lower causation standard than in ordinary tort cases and reflects the historical vulnerability of seamen at sea.

Jones Act claims may be brought in either federal or state court, at the seaman's election. Louisiana state courts have jurisdiction over Jones Act claims and are frequently chosen by plaintiffs whose counsel prefer a Louisiana jury over a federal bench trial.

Seaman Status: The Threshold Question

The right to pursue a Jones Act claim depends entirely on whether the injured worker qualifies as a Jones Act seaman. The threshold is not met by all maritime workers — only those who meet the requirements established by the U.S. Supreme Court in Chandris, Inc. v. Latsis, 515 U.S. 347 (1995).

We explain how fault percentages and deadlines work after a Louisiana injury in our 2026 Tort Reform Survival Guide.

Under Chandris, a worker qualifies as a Jones Act seaman if they:

• Contribute to the function of a vessel or the accomplishment of its mission — this is broadly interpreted and typically satisfied by any worker who performs functions aboard a vessel that relate to the vessel's maritime purpose.
• Have a connection to a vessel (or fleet of vessels) that is substantial in both duration and nature — courts apply a practical benchmark of 30% of total working time in service of a vessel as the durability standard. Workers who spend less than 30% of their time aboard vessels generally do not qualify.

The seaman status question is most frequently contested in oilfield and offshore practice for workers who divide their time between vessel-based work and onshore or fixed-platform assignments. A driller assigned exclusively to a drillship is clearly a seaman. A service technician who spends two weeks offshore on a semisubmersible and then returns to shore for weeks or months may not qualify. The factual development of the worker's entire work history — every hitch, every assignment, every location — is necessary to properly evaluate seaman status.

Jones Act Negligence: What Must Be Proved

Under the Jones Act, the seaman must prove that the employer (or the employer's agents, officers, or co-employees) was negligent and that the employer's negligence played a part — however slight — in causing the injury. This is the lightest causation standard in American tort law. The seaman does not need to prove that employer negligence was the primary or predominant cause; any contribution, however minor, is sufficient to establish causation.

Common Jones Act negligence theories in oilfield and offshore cases include: failure to provide a safe place to work, failure to properly maintain equipment, failure to provide adequate and properly trained crew, failure to establish and enforce safety procedures, failure to respond appropriately to known hazards, and failure to take corrective action after prior incidents involving the same condition.

Damages recoverable in a Jones Act negligence claim include: past and future medical expenses, past and future lost wages at full replacement value (not capped at two-thirds), physical pain and suffering, mental anguish, loss of enjoyment of life, and permanent disability or disfigurement. Loss of consortium for the seaman's spouse is also available in Louisiana courts.

Unseaworthiness: A Strict Liability Claim Against the Vessel Owner

Separate from and in addition to the Jones Act negligence claim, an injured seaman has a general maritime law claim for unseaworthiness against the vessel owner. Unseaworthiness is a strict liability doctrine — the seaman does not need to prove negligence, only that the vessel was not reasonably fit for its intended purpose at the time of the injury.

A vessel is unseaworthy if any of the following conditions existed and contributed to the injury: defective equipment or tools (a broken ladder, a defective winch, a slippery deck); an unsafe crew (insufficiently trained, inadequate in number, or incompetent); defective appurtenances (items carried aboard and used in the vessel's operations, including cargo); or unsafe work methods imposed by the vessel owner for use aboard the vessel.

Unseaworthiness and Jones Act negligence claims are typically brought together in the same lawsuit. The vessel owner who is the seaman's employer faces both claims; where the vessel owner and the employer are different entities, the unseaworthiness claim runs against the vessel owner and the Jones Act negligence claim runs against the employer.

Maintenance and Cure: The Strict Liability Compensation Obligation

Maintenance and cure is one of the oldest obligations in maritime law, predating the Jones Act by centuries. It requires the vessel owner or employer to pay an injured seaman's daily living expenses (maintenance) and medical expenses (cure) following a work-related injury or illness — regardless of fault and regardless of whether the employer was negligent. It is a strict liability obligation, not a negligence claim.

Maintenance is paid as a daily allowance intended to cover the seaman's reasonable living expenses — housing, food, and utilities — while the seaman is unable to return to duty. The daily maintenance rate has historically been the subject of dispute, with employers setting contractual rates that courts may find inadequate. An injured seaman who believes their maintenance rate is below their actual reasonable expenses may seek a higher rate through litigation.

Cure covers all reasonable and necessary medical expenses — physician visits, hospitalizations, surgery, physical therapy, prescription medications, and diagnostic testing — until the seaman reaches maximum medical improvement (MMI). At MMI — the point at which further treatment will not improve the seaman's condition — the cure obligation ends. Disputes about when MMI has been reached are common and can be resolved through litigation.

Unearned wages are also owed for the duration of the voyage during which the seaman was injured. Together, maintenance, cure, and unearned wages form the baseline obligation the employer owes to every injured seaman, independent of any negligence claim. An employer who willfully or arbitrarily refuses to pay maintenance and cure faces an additional damages award — including attorneys' fees — as a penalty for the refusal.

The LHWCA: For Maritime Workers Who Are Not Seamen

Workers who perform maritime work but do not qualify as Jones Act seamen — offshore platform workers on fixed platforms, longshoremen, harbor workers, and many OCS workers — may be covered by the Longshore and Harbor Workers' Compensation Act (LHWCA, 33 U.S.C. § 901 et seq.). The LHWCA is a federal workers' compensation system that provides: medical expenses paid directly to providers, weekly indemnity at two-thirds of average weekly wage up to the statutory maximum, vocational rehabilitation, and death benefits for surviving dependents.

The LHWCA bars the covered worker from suing their employer in negligence — it is the exclusive remedy against the employer, similar to Louisiana workers' comp for land-based workers. However, the LHWCA specifically preserves the worker's right to sue a vessel owner for vessel negligence under 33 U.S.C. § 905(b), even if the vessel owner is also a third party in the case. LHWCA claims must be filed with the Office of Workers' Compensation Programs (OWCP) within one year of the injury.

Frequently Asked Questions

What is the Jones Act and who does it protect?

The Jones Act (46 U.S.C. § 30104) is a federal statute giving qualified seamen — crew members of vessels in navigation — the right to sue their employer for negligence and recover full tort damages including pain and suffering, future wages at full replacement, and loss of enjoyment of life. It is not a workers' compensation system — it is a tort claim with a negligence standard, a three-year limitation period, and access to a jury trial.

How is seaman status determined under the Jones Act?

Under Chandris, Inc. v. Latsis (1995), a worker must: (1) contribute to the function or mission of a vessel; and (2) have a connection to the vessel that is substantial in duration and nature — practically, at least 30% of total working time in service of a vessel. Workers who split time between vessels and land or fixed platforms may or may not qualify, depending on their full work history.

What is maintenance and cure under maritime law?

Maintenance and cure is a strict liability obligation — owed regardless of fault — requiring the employer to pay the injured seaman's daily living allowance (maintenance) and all reasonable medical expenses (cure) until maximum medical improvement. It runs alongside and independently of any Jones Act negligence claim. Willful refusal to pay maintenance and cure can result in punitive damages and attorneys' fees.

What is unseaworthiness under general maritime law?

Unseaworthiness is a strict liability claim against the vessel owner for failing to provide a vessel reasonably fit for its intended purpose. No proof of negligence is required — only that an unseaworthy condition (defective equipment, unsafe crew, unsafe work methods, defective gear) caused the injury. It is typically brought alongside a Jones Act claim in the same lawsuit.

How does the LHWCA differ from the Jones Act for Louisiana offshore workers?

The LHWCA covers non-seaman maritime workers and provides workers' comp-style benefits (medical expenses, two-thirds wage indemnity) without the right to sue the employer in negligence. It also allows a vessel negligence claim against the vessel owner under 33 U.S.C. § 905(b). LHWCA claims have a one-year filing deadline. The Jones Act allows full negligence litigation against the employer with full tort damages and a three-year limitation period — significantly more powerful for seriously injured workers who qualify as seamen.
