The short version
- An offshore injury is, broadly, harm a worker suffers on or around the water: on vessels, rigs, fixed platforms, supply boats, docks, and wind installations.
- Whether an injury qualifies for a legal claim depends less on the word "offshore" and more on where you were hurt and your connection to a vessel.
- Four federal laws do most of the work: the Jones Act (seamen), the LHWCA (dock and harbor workers), OCSLA (fixed platforms on the outer continental shelf), and DOHSA (deaths far out at sea).
- The same accident can touch more than one law, and the wrong classification can quietly cost a worker the bulk of a recovery.
- Deadlines differ by law. Some are three years; some give as little as 30 days for notice. Acting early protects the claim.
- A specialist maritime attorney can tell you which law fits your facts and what your claim may be worth.

What Counts as an Offshore Injury?
Quick answer
An offshore injury is harm a worker suffers on or around the water, beyond the shoreline, on vessels, rigs, platforms, docks, or supply boats. For a legal claim, what counts as an offshore injury depends on where it happened and your connection to a vessel, because that decides which law applies.
If you were hurt at sea or near it, the first thing to understand is what counts as an offshore injury in the eyes of the law. In everyday speech, "offshore" just means out on the water. In a legal claim, the word carries more weight, because the location of the injury and the kind of work you do decide which federal law protects you and how much you can recover.
Broadly, an offshore injury is any work-related harm connected to maritime activity beyond the shoreline. That includes injuries on cargo ships, tankers, tugboats, crew boats, and supply vessels; on mobile drilling rigs and fixed production platforms; on docks, piers, and in shipyards; and on the newer offshore wind installations now rising off the coasts. A fall on a slick deck, a crush injury from cargo gear, a burn from an engine-room fire, and a back injury from heavy lifting on a rig can all qualify.
Why the label matters so much
On land, almost every workplace injury runs through one system: state workers' compensation. Offshore, that is not true. Several federal laws overlap, each written for a different kind of worker and a different place. The same accident can fall under one law for a deckhand and a different one for a platform worker a few feet away. Naming the injury correctly is not a technicality. It shapes who you can sue, what you must prove, and what your claim is worth.
Whether your injury qualifies is less about the word "offshore" and more about where you were hurt and your tie to a vessel. That is what selects the law.
Where It Happened and Who Is Covered
Quick answer
Coverage turns on two questions: where the injury happened (state waters, a dock, a fixed platform, or the high seas) and your job (vessel crew, dock worker, or platform worker). Together they point to the governing law.
Once an injury is maritime, the next step is to place it. Two facts drive almost every offshore injury question: the location of the accident and the nature of your work. Get those two right and the correct legal framework usually follows.
Location
Maritime law treats a moving deck very differently from a fixed platform bolted to the seabed, and both differently from a dock. Inside state waters, on a vessel, on a structure attached to the outer continental shelf, or miles out on the open ocean: each location pulls in a different statute. A navigable water is one that forms a continuous highway for interstate or foreign commerce, and much of maritime jurisdiction starts there.
Who you are at work
The other half is your role. A seaman assigned to a vessel, a longshore or harbor worker loading ships at a terminal, and a platform worker on a fixed rig are covered by different laws even if they are hurt the same way. You can see the full range of situations on our offshore case types overview.
Two questions decide coverage: where you were hurt and what you do. Everything else builds on those answers.
The Jones Act: Injured Seamen and Vessel Crew
Quick answer
The Jones Act covers seamen, the crew members with a substantial connection to a vessel in navigation. It lets them sue an employer for negligence and recover full damages, including pain and suffering, with a right to a jury trial.
The Jones Act (46 U.S.C. § 30104) is the law most people picture when they think of an offshore injury. It protects seamen: workers whose duties contribute to a vessel and who have a connection to that vessel, or a fleet, that is substantial in time and nature. Courts use a rough guide of about 30 percent of work time aboard, drawn from the Supreme Court's decision in Chandris, Inc. v. Latsis (1995).
What makes the Jones Act powerful is the remedy. Unlike no-fault systems, it is fault-based but pays in full: lost past and future wages, the entire cost of medical care, and pain and suffering. The causation standard is famously low, sometimes called featherweight causation, meaning the employer can be liable if its fault played any part, however slight, in the injury.
Claims that often travel together
Injured seamen frequently hold more than one claim at once. Maintenance and cure is an ancient, no-fault right to a daily living allowance and medical care until maximum recovery. Unseaworthiness is a separate claim against the vessel owner for unsafe equipment or conditions. These stack with a negligence claim, which is part of why maritime cases can be valuable.
Because seaman status is the gateway and employers fight it hard, it deserves a careful look. Our companion guide, what is the Jones Act, walks through the seaman test and the remedies in depth.
If you crew a vessel, the Jones Act is likely your route, and it can be worth far more than workers' compensation.
The LHWCA: Dock, Harbor, and Shipyard Workers
Quick answer
The Longshore and Harbor Workers' Compensation Act is a federal no-fault system for maritime workers who are not seamen, such as longshoremen, harbor workers, and shipbuilders. It pays scheduled medical and disability benefits without proof of fault.
Not every offshore injury happens to a vessel crew member. Many of the most common ones happen to the people who load and unload ships, repair them, and work the terminals. For them, the Longshore and Harbor Workers' Compensation Act (LHWCA), 33 U.S.C. § 901 and following, is usually the governing law.
The LHWCA is a no-fault system, much like state workers' compensation but federal. An injured longshoreman does not have to prove the employer was careless. In exchange, the benefits are scheduled: medical treatment and a portion of lost wages, administered through the U.S. Department of Labor. It generally does not provide the pain-and-suffering damages a seaman can pursue under the Jones Act.
The status and situs test
LHWCA coverage turns on two ideas: status (you do maritime work, such as loading, repairing, or building vessels) and situs (you were hurt on or near navigable waters, including adjoining piers, wharves, and terminals). A worker who is a true seaman is excluded, because that worker belongs to the Jones Act instead.
The line between the two is exactly where many disputes live, and it is worth getting right early. Our overview of offshore injury claims lays out how these categories interact.
Dock, harbor, and shipyard workers usually fall under the LHWCA, a federal no-fault program, not the Jones Act.
OCSLA: Fixed Platforms and the Outer Continental Shelf
Quick answer
The Outer Continental Shelf Lands Act covers workers on fixed platforms and structures attached to the seabed beyond state waters. It extends LHWCA benefits to them and adopts the adjacent state's law as a backstop.
Some of the most serious offshore injuries happen on fixed production platforms standing miles out at sea, beyond the three-mile band of state waters. Those workers are usually not seamen, because a fixed platform is not a vessel in navigation. For them, the Outer Continental Shelf Lands Act (OCSLA), 43 U.S.C. § 1331 and following, fills the gap.
OCSLA, passed in 1953, treats the outer continental shelf as an area of federal control and extends the LHWCA's no-fault benefits to workers injured there during operations like drilling and production. It also borrows the law of the nearest state to fill gaps. The practical effect: a platform worker hurt offshore often has a federal no-fault remedy even though no vessel was involved.
A growing reach: offshore wind
OCSLA is no longer just about oil and gas. The Department of Labor amended its reach so that workers building and maintaining offshore wind energy projects on the shelf are covered too. As wind farms multiply off the Atlantic coast, this is a more common path for injured crews.
Platform injuries also raise hard questions about how much a claim is worth, since the available benefits differ from a Jones Act case. Our article on what an offshore platform injury claim is worth digs into that.
Workers on fixed platforms on the outer continental shelf are usually covered through OCSLA, which carries LHWCA benefits out to sea.
DOHSA, General Maritime Law, and Finding an Attorney
Quick answer
The Death on the High Seas Act covers wrongful death more than three nautical miles from shore. General maritime law fills remaining gaps. Because the laws overlap, an offshore accident attorney is the safest way to find your path.
The hardest offshore cases are the fatal ones. When a worker or passenger is killed more than three nautical miles from the U.S. shore, the Death on the High Seas Act (DOHSA), 46 U.S.C. § 30302, often governs. The personal representative of the person who died brings the claim for the benefit of a spouse, parent, child, or dependent relative, and recovery is limited to pecuniary, or financial, losses. A seaman killed beyond that line is generally covered by the Jones Act instead.
Underneath all of these statutes sits general maritime law, the body of judge-made admiralty rules that supplies remedies like maintenance and cure and unseaworthiness when a statute does not. Together, these laws form an overlapping web, and the same accident can implicate more than one.
How to find the right help
Because the categories overlap, the single most useful step is to talk to a lawyer who lives in this field. A strong offshore accident attorney can look at where you were hurt and what you do, identify the law that applies, and tell you what your claim may be worth. Look for real maritime concentration, cases actually handled under the relevant law, and a contingency fee so you pay nothing unless you recover.

Frequently asked questions
What counts as an offshore injury?
An offshore injury is generally any harm a worker suffers in connection with work on or around the water, beyond the shoreline. That includes injuries on vessels, drilling rigs, fixed platforms, supply boats, docks, and wind installations. What counts as an offshore injury for legal purposes depends less on the word "offshore" and more on where the injury happened and your connection to a vessel, because that decides which federal law applies.
Which law applies to my offshore injury?
It depends on your job and where you were hurt. Vessel crew with a substantial connection to a vessel usually fall under the Jones Act. Dock, harbor, and shipyard workers often fall under the LHWCA. Workers on fixed platforms on the outer continental shelf are typically covered through OCSLA. Deaths more than three nautical miles out may fall under DOHSA. The categories overlap, so the facts matter.
Is an injury on an oil rig covered?
Usually yes, but the law that applies depends on the type of rig. Crew on a floating or moveable drilling vessel may be seamen under the Jones Act. Workers on a fixed platform attached to the seabed on the outer continental shelf are generally covered through OCSLA, which extends LHWCA benefits to them. The structure type and your role drive the answer.
What is the difference between the Jones Act and the LHWCA?
The Jones Act lets a seaman sue an employer for negligence and recover full damages, including pain and suffering, with a right to a jury trial. The LHWCA is a federal no-fault system that pays scheduled medical and disability benefits to dock and harbor workers who are not seamen. The dividing line is your connection to a vessel in navigation.
Does OCSLA cover offshore wind farm workers?
In many cases, yes. The Outer Continental Shelf Lands Act was amended so its coverage reaches workers involved in the construction and maintenance of offshore wind energy projects on the outer continental shelf, extending LHWCA benefits to them. Coverage still turns on the specific facts, so a maritime attorney should review your situation.
What is DOHSA and when does it apply?
The Death on the High Seas Act provides a wrongful death remedy when a person is killed more than three nautical miles from the U.S. shore. The personal representative brings the claim for the benefit of the spouse, parent, child, or dependent relative, and recovery is limited to pecuniary losses. A seaman killed beyond that line is usually covered by the Jones Act instead.
How long do I have to file an offshore injury claim?
Maritime injury claims generally carry a three-year filing deadline under 46 U.S.C. § 30106, but LHWCA claims have their own notice and filing windows, often as short as thirty days for notice and one year to file. Because the deadlines differ by law, you should confirm yours with an attorney quickly. Waiting risks losing the claim entirely.
How do I find an offshore accident attorney?
Look for an offshore accident attorney who concentrates in maritime injury, has handled cases under the specific law that applies to you, and works on a contingency fee so you pay nothing unless you recover. Ask about experience with the Jones Act, LHWCA, OCSLA, or DOHSA as relevant, and confirm all fee terms in writing before signing.
