Maritime Brain Injuries: Your Rights After an Offshore Head Injury

A blow to the head offshore is not just another bump. When a falling tool, a slip on a wet deck, or a collision injures your brain, the consequences can follow you for the rest of your life, and the law that protects you is unlike anything a land-based worker relies on.

This article is for informational purposes only and does not constitute legal or medical advice. Maritime brain-injury claims turn on specific facts, and time limits apply. To understand your own rights, consult a licensed maritime attorney.

Key Facts at a Glance

• The CDC recorded 68,663 TBI-related deaths in 2023 and roughly 214,110 TBI-related hospitalizations in 2020, and a traumatic brain injury contributes to about 30% of all U.S. injury deaths.
• Doctors grade brain-injury severity on the Glasgow Coma Scale: mild (13 to 15), moderate (9 to 12), and severe (3 to 8).
• Even a “mild” TBI, the medical term for a concussion, can leave lasting headaches, memory loss, and mood change; about 15% of mild cases still have symptoms three months later.
• The Jones Act, 46 U.S.C. § 30104, lets an injured seaman sue an employer under a “featherweight” causation standard set in Rogers v. Missouri Pacific R.R. (1957).
• A brain-injured seaman is owed maintenance and cure until reaching maximum medical improvement, regardless of fault.
• Most maritime injury claims must be filed within three years under 46 U.S.C. § 30106.
• An employer can try to deny benefits by claiming you hid a prior head injury, the McCorpen concealment defense, but it carries a strict three-part test.

Offshore work punishes the head. Crew move heavy steel on pitching decks, stand beneath suspended loads, and work in cramped spaces where a single misstep ends in a skull striking a hatch coaming or a winch. When the brain is the part that gets hurt, the stakes are categorically different from a broken wrist. A brain injury can quietly rewrite a worker’s memory, temper, balance, and earning power, and it often does so in ways that do not show up on a first X-ray or in a company medic’s quick check.

That is also why brain-injury claims are among the most contested in maritime law. Employers and their insurers know these cases carry the highest values, so they move fast to label the injury “mild,” to question whether you were really a seaman, and to comb your history for an old concussion they can blame instead. This guide explains how these injuries happen at sea, how medicine grades them, which federal laws apply, what your claim may be worth, and the specific traps that cost injured crew their compensation.

How Do Maritime Workers Suffer Brain Injuries Offshore?

Offshore brain injuries usually come from one of four mechanisms: a fall, a falling or swinging object, a vessel impact, or a blast. Each is common in the maritime workplace, and each can produce a closed head injury that looks minor at the scene yet damages the brain inside the skull.

A deckhand who slips on spilled hydraulic fluid and strikes his head on a bitt, a roustabout hit by a load swinging from a crane, a galley worker thrown across a compartment when a supply vessel takes a wave broadside, and a worker caught in a fire or explosion in a confined space can all sustain a traumatic brain injury. The U.S. Bureau of Labor Statistics tracks the water transportation sector among the more hazardous U.S. industries for serious occupational injury (Source: U.S. Bureau of Labor Statistics). The common thread is force transmitted to the brain, whether by direct impact or by the brain moving violently within the skull.

Why offshore TBIs get missed. A worker who is dazed but conscious often refuses to be the one who stops the job. Symptoms like headache, irritability, and slowed thinking can take hours or days to appear, and by then the crew has rotated, the deck has been cleaned, and the company medic has logged it as a minor bump. Delay is the enemy of both recovery and proof.

What Are the Types and Severity Levels of a Traumatic Brain Injury?

A traumatic brain injury is any disruption of normal brain function caused by a bump, blow, jolt, or penetrating wound. Doctors classify the initial severity with the Glasgow Coma Scale (GCS), a 3-to-15 score of eye, verbal, and motor response, then describe the specific injury type, such as concussion, contusion, or diffuse axonal injury.

The severity label matters legally as well as medically, because it shapes the prognosis, the cost of future care, and the value of the claim. The table below maps the standard GCS bands to their medical meaning and to what each typically means for an offshore claim. It is the kind of crossover reference the law-firm pages ranking for this topic do not provide.

Common offshore TBI types include the concussion (a mild TBI from a blow or jolt), the contusion (a bruise with localized bleeding), and diffuse axonal injury (widespread tearing of nerve fibers from rotational force, often the most devastating). Repeated concussions, a real risk for career crew, are linked to chronic traumatic encephalopathy and long-term cognitive decline (Source: CDC).

Which Maritime Laws Cover a Brain Injury at Sea?

Which law governs your brain-injury claim depends on what kind of maritime worker you are and where you were hurt, not on how serious the injury is. The four federal frameworks below cover almost every offshore head-injury scenario, and identifying the right one is the first thing that determines what you can recover.

The dividing line that matters most for head injuries is seaman status. A seaman who suffers a TBI has the powerful Jones Act and unseaworthiness remedies; a non-seaman injured on a dock is usually limited to LHWCA benefits that do not include pain and suffering. Courts decide status under the Chandris guideline that a worker generally must spend about 30% of working time in service of a vessel. If your status is unclear, that question alone can change your case by hundreds of thousands of dollars, which is covered in our guide on whether you qualify as a Jones Act seaman.

What Are the Three Ways an Injured Seaman Can Recover for a Brain Injury?

A seaman with a brain injury usually has three overlapping claims, and a competent case pursues all three at once because they cover different gaps. They are Jones Act negligence, unseaworthiness, and maintenance and cure.

Under the Jones Act, an injured seaman need only prove the employer’s negligence played “any part, even the slightest” in causing the harm. Courts call this the “featherweight” causation standard, and it is far easier to meet than ordinary negligence.

Worked example. Suppose a deckhand is struck in the head by a tag line that parted because it was visibly frayed. Under ordinary negligence law he might struggle to prove the employer should have caught it. Under the Jones Act featherweight standard, evidence that the company failed to inspect or replace worn lines, contributing even slightly to the injury, can establish liability. The same frayed line can independently make the vessel unseaworthy, a strict-liability theory that does not require proving the employer was careless at all. Our overview of what makes a vessel unseaworthy explains that second pillar in depth.

How Much Is a Maritime Brain Injury Claim Worth?

There is no single number. A maritime brain-injury claim is worth the full economic and human cost the injury imposes, which depends on severity, the strength of the liability proof, your lost earning capacity, and the lifetime cost of care. The honest answer is that it varies enormously, and any site quoting a fixed “average” for a TBI is selling certainty that does not exist.

What can be said with data is that brain injuries sit at the top of the value range. The CDC estimates the total annual healthcare cost of nonfatal TBIs in the United States exceeds $40.6 billion (Source: CDC), and severe cases routinely require lifelong rehabilitation. Reported maritime results reflect that scale. Maritime firms have publicly reported individual outcomes such as a $30 million settlement for a Jones Act seaman with a traumatic brain injury (Source: Zehl & Associates) and a $13.1 million recovery for a shipyard deckhand left with severe brain damage (Source: Schechter, Shaffer & Harris). These are reported individual results, not typical outcomes, and your own case depends entirely on its facts.

A full-value brain-injury claim generally accounts for past and future medical care and rehabilitation, past and future lost wages, lost earning capacity when the worker cannot return to maritime work, pain and suffering, and the cognitive and emotional toll on daily life. For a deeper look at how maritime damages are built, see our guide to Jones Act settlement amounts.

The undervaluation trap. The cases most often shortchanged are not the comas; they are the “mild” concussions whose cognitive deficits surface weeks later. Accepting a quick settlement before a neurologist has measured the damage can leave a worker paying for a brain injury out of pocket for life.

What Is Maintenance and Cure for a Brain-Injured Seaman?

Maintenance and cure is a no-fault right that begins the moment a seaman is injured in the service of a vessel. “Maintenance” is a daily stipend for food and lodging ashore while you recover; “cure” is payment of reasonable and necessary medical treatment until you reach maximum medical improvement (MMI), the point at which further treatment would only be palliative rather than curative.

For a brain injury, the cure obligation is significant because diagnosis and rehabilitation, neurology, neuropsychological testing, cognitive therapy, can stretch for many months. An employer who unreasonably refuses or cuts off these payments can be liable for punitive damages and attorney’s fees, a rule the U.S. Supreme Court confirmed in Atlantic Sounding Co. v. Townsend (2009). Doubts about whether you have reached MMI are resolved in the seaman’s favor. Our dedicated guide to maintenance and cure covers the rates and disputes in detail.

Worked example. A seaman with a moderate TBI is declared “at MMI” by a company-chosen doctor four months after the injury so the carrier can stop paying cure. His own neurologist documents ongoing cognitive therapy that is still improving his function. Because the treatment is still curative rather than merely palliative, he has not reached MMI, the cure obligation continues, and a premature cutoff can expose the employer to bad-faith damages.

Can the Company Use a Prior Concussion Against You? The McCorpen Defense

Yes, employers regularly try, and this is one of the most important traps in a head-injury case. The defense comes from McCorpen v. Central Gulf Steamship Corp., 396 F.2d 547 (5th Cir. 1968), which lets an employer cut off maintenance and cure if a seaman concealed a relevant pre-existing condition when hired. Because many career mariners have an old sports concussion or prior head knock, carriers comb medical and employment records looking for one.

The defense is not automatic. To win it, the employer must prove all three of the following:

1. You intentionally misrepresented or concealed medical facts, typically by answering a pre-hire medical questionnaire falsely.
2. The concealed facts were material to the employer’s decision to hire you.
3. There is a causal connection between the concealed condition and the injury you are now claiming.

Each element is contestable. If the employer never asked, never required a medical exam, or asked vaguely, intentional concealment is hard to prove. And critically, even a successful McCorpen defense only forfeits maintenance and cure going forward; the Fifth Circuit held in Boudreaux v. Transocean Deepwater, Inc., 721 F.3d 723 (5th Cir. 2013) that the employer cannot claw back benefits it already paid, and concealment does not by itself bar the underlying Jones Act negligence claim.

A prior concussion does not erase your rights. The McCorpen defense fails unless the company proves intentional concealment of a material condition that is causally linked to the new injury, and it never reaches your Jones Act negligence claim.

Why Are “Mild” Brain Injuries So Dangerous to Your Claim?

Because the word “mild” describes the initial score, not the eventual outcome, and insurers exploit the gap. A mild TBI is a concussion, a GCS of 13 to 15, often with normal scans. Yet roughly 15% of people with a mild TBI still have symptoms three months later (Source: CDC), and post-concussion headaches, memory problems, irritability, and difficulty concentrating can quietly end a maritime career.

Two things make these cases vulnerable. First, the symptoms are invisible and delayed, so the early record looks unremarkable and the company argues nothing serious happened. Second, the deadline keeps running while you wait to feel better. Accepting a fast settlement, or simply letting the clock run, can foreclose the claim before the true damage is documented by a neurologist or neuropsychologist. The defense playbook is predictable, and our guide to comparative negligence in maritime cases explains the related tactic of blaming the worker to shave the recovery.

How Long Do You Have to File a Maritime Brain Injury Claim?

In most cases, three years from the date of injury. The general maritime statute of limitations, 46 U.S.C. § 30106, gives a seaman three years to file Jones Act and unseaworthiness claims. But that single number hides several traps, and a brain injury makes the deadline easy to miss.

A cognitive injury can delay the very awareness that you have a claim, and employers know it. Do not assume the deadline is far off, because a non-seaman classification or an OCSLA state-law borrow can shorten it to a year or less.

What Should You Do After a Head Injury Offshore?

Act as though the injury is serious even if you feel only dazed, because the early steps protect both your brain and your claim. The following sequence matters.

1. Report it and get a real medical evaluation. Insist on a documented exam, not a quick look from the medic. Tell the provider every symptom, including headache, nausea, confusion, and light sensitivity.
2. Insist on neurological imaging and follow-up. A normal scene assessment does not rule out a concussion. Ask for, and document requests for, neurology referral.
3. Write down what happened while it is fresh. Record the cause, the conditions, the equipment involved, and any witnesses. A cognitive injury can erode your own memory of the event.
4. Preserve the evidence. Note the frayed line, the missing guard, the wet deck. Ask that the scene and equipment be preserved before they are cleaned or repaired.
5. Do not sign anything or accept a quick settlement. Recorded statements and early releases are designed to limit your claim before the damage is known.
6. Talk to a maritime attorney before the deadline runs. Brain-injury value depends on documentation that takes time to build.

If a head injury was fatal, surviving family members may have a wrongful-death claim under the Jones Act or DOHSA depending on where the death occurred. Those rights also carry deadlines.

Frequently Asked Questions

Can you sue for a brain injury suffered at sea?

Yes. If you are a seaman, the Jones Act lets you sue your employer when its negligence played even the slightest part in causing your brain injury, and you may also have an unseaworthiness claim against the vessel. Non-seamen injured on docks or platforms generally recover through the LHWCA or OCSLA instead. A free case review can confirm which path fits your situation.

How much is a maritime brain injury settlement worth?

It depends on severity, liability, lost earning capacity, and lifetime care costs, so there is no reliable “average.” Brain injuries sit at the high end of maritime claim values; reported individual maritime TBI results have ranged into the millions and, in severe cases, tens of millions, but those are specific outcomes and not predictions for any other case.

Is a concussion considered a traumatic brain injury?

Yes. A concussion is the medical term for a mild traumatic brain injury, a GCS of 13 to 15. “Mild” refers to the initial severity, not the lasting impact; about 15% of people with a mild TBI still have symptoms three months later, which is why these cases are frequently undervalued.

What happens to my claim if I had a previous head injury?

A prior concussion does not bar your claim. An employer may raise the McCorpen defense to stop maintenance and cure, but only if it proves you intentionally concealed a material, causally related condition when hired. Even a successful McCorpen defense does not reach your Jones Act negligence claim and cannot claw back benefits already paid.

How long do I have to file a maritime injury claim?

Usually three years from the date of injury under 46 U.S.C. § 30106 for Jones Act and unseaworthiness claims. LHWCA and OCSLA workers can face much shorter windows, sometimes a year or less, so a brain-injured worker should not assume the deadline is far away.

What is maintenance and cure for a brain injury?

Maintenance and cure is a no-fault benefit owed to an injured seaman regardless of who was at fault. Maintenance covers daily living costs ashore; cure pays for reasonable medical treatment until you reach maximum medical improvement. For a brain injury that often means months of neurological care, and an employer who cuts it off too early can owe punitive damages.

Who is liable for an offshore head injury?

It can be the employer (for negligence under the Jones Act), the vessel owner (for an unseaworthy condition), or a third party such as an equipment manufacturer or another contractor on the job. Many offshore operations involve multiple companies, so a brain-injury case often pursues more than one responsible party.

Do I need a maritime lawyer for a brain injury claim?

Brain-injury cases are the ones insurers fight hardest and value highest, and the proof, neurological documentation, seaman status, and liability evidence, takes time and expertise to build. A maritime attorney handles that analysis and protects the deadline. You can request a free, no-obligation review to understand your options.
