Offshore oil & gas is where the Jones Act does its most important work. The rigs are massive, the equipment is deadly, the crews work 12-hour tours for weeks at a time, and when things go wrong they go wrong spectacularly. The industry generates more Jones Act cases — and more seven-figure recoveries — than any other vessel category.

It's also the category where employer and insurer defenses are most aggressive, best-funded, and most practiced. The companies that operate offshore rigs have been defending Jones Act cases for 80 years. Their playbook is well-rehearsed. Countering it requires a lawyer who has seen the playbook before.

Who's covered: vessels and roles.

The Jones Act applies to essentially every worker on a vessel "in navigation" offshore. In practice, that means:

Mobile drilling units. Drillships, jackup rigs, semisubmersibles. All vessels for Jones Act purposes. Roughnecks, drillers, motormen, derrickhands, mud engineers, toolpushers, company men — all potentially seamen.

Production platforms with vessel status. Many FPSOs (floating production, storage, and offloading units) qualify as vessels because they remain connected to their moorings only loosely and retain the ability to navigate. Fixed platforms, by contrast, are often not vessels — workers on those may fall under the Outer Continental Shelf Lands Act instead, which borrows the LHWCA framework.

Offshore service vessels. Supply boats (OSVs), crew boats, anchor-handling tugs, lift boats, workover vessels. Clearly vessels. Deckhands, mates, captains, engineers all covered.

Galley and service personnel. Cooks, stewards, laundry workers, medics aboard rigs. Yes, covered — their work contributes to the rig's function by keeping the crew operational.

Fixed Platforms Aren't Vessels If you were hurt on a fixed production platform — one that stands on legs driven permanently into the sea floor — you probably aren't covered by the Jones Act. You're likely covered by the Outer Continental Shelf Lands Act, which applies the LHWCA to platform workers. LHWCA is better than state workers' comp but not as favorable as the Jones Act. Whether the platform counts is often a key early question — and one the employer has every incentive to get wrong.

How offshore injuries happen.

The offshore industry has developed predictable injury patterns over decades. The locations and mechanisms below cover the majority of claims we see:

  • Dropped ObjectsTools, pipe, equipment falling from the derrick, the drill floor, or the crane. Often catastrophic — fatalities and traumatic brain injuries. Nearly always involves some form of rig negligence (tethering failures, inadequate barricading, crew error).
  • Pipe HandlingMaking or breaking connections, tripping pipe, tongs and spinners. Crushed hands, amputations, shoulder injuries. Mechanism of injury is often equipment that should have been taken out of service.
  • Crane & RiggingDropped loads, shifted cargo, swing-rope transfers, personnel baskets. Highest-severity claims — and usually involve a crane operator or rigger decision that will be scrutinized.
  • Slips & FallsWet decks, oil spills, inadequate grating, poor lighting, missing handrails. Dismissed as "minor" but often produce serious back and shoulder injuries. Unseaworthiness claims for deck conditions.
  • Chemical ExposureH2S, produced water, drilling mud, solvents. Acute and long-term respiratory, neurological, and cancer claims. Documentation of exposure is critical.
  • Personnel TransferSwing rope, basket transfer, helicopter crew change. Low-frequency, high-severity — injuries here are almost always catastrophic.

What your case is worth.

Offshore oil & gas cases produce the highest settlements and verdicts in maritime law, for three reasons.

First, wages are high. A drillship motorman on a 14/14 rotation makes $100,000-$180,000 a year. A driller makes $200,000+. Future-wages calculations on career-ending injuries reach millions.

Second, the injuries are severe. The heavy equipment, the fall hazards, the pressure systems, the chemical environment — when offshore injuries happen, they tend not to be minor.

Third, the unseaworthiness doctrine is powerful in this context. Rigs have more parts, more systems, more potential failure points than most vessels. Unseaworthiness claims — which are no-fault, strict-liability claims against the vessel — stick in these cases the way they don't in simpler environments.

Typical case values for properly-prepared offshore O&G cases:

Soft-tissue back/shoulder injury, returned to work: $120,000-$350,000.

Surgical injury, return to modified duty: $400,000-$900,000.

Surgical injury, career-ending: $1,200,000-$3,500,000+.

Traumatic brain injury, amputation, catastrophic: $3,000,000-$10,000,000+.

Numbers vary widely by venue, employer, specific facts, and quality of defense. Eastern District of Louisiana verdicts trend higher than some other offshore venues. Cases against household-name operators (majors) often settle higher than cases against smaller independents. Facts like a violated written safety policy, a prior incident on the same equipment, or a whistleblower willing to testify can move the numbers significantly.

What to do right now.

If you've just been hurt offshore, the first 72 hours matter more than any other part of your case. Some specific points:

Report it, in writing, to someone with authority. Make sure there's a written record of the incident that includes your description of what happened. If your employer's incident report leaves out key facts or misrepresents them, write your own account and sign and date it.

Get real medical attention from someone other than the company doctor. The rig medic or company-contracted physician works for the operator. You have the right to your own doctor. Get one as soon as you're back ashore.

Don't sign anything the company puts in front of you, especially a release. Companies sometimes approach injured workers within days of an incident with cash offers tied to a signed release. These offers are almost always a tiny fraction of what the case is worth.

Document everything. Save text messages, emails, photos, hitch schedules, pay stubs, the names of crew members who witnessed the event. The paper trail is often what makes the difference six months later.

Talk to a maritime lawyer before you talk to an adjuster. A free case review costs nothing and takes 20 minutes. Adjusters record calls and use what you say against you.

A full treatment of the first-72-hours playbook is coming in a future guide. Until then, the single most important action is the last one: talk to a lawyer before anyone else talks you into anything.
