A fixed platform is not a vessel — so the law is OCSLA, not the Jones Act.
A platform bolted to the seabed is the legal opposite of a ship. That single fact moves the case out of the Jones Act and into OCSLA and borrowed state law — including the defense's favorite shield.
Is a fixed platform a vessel, and what law covers an injury on it?
Generally no. A fixed platform is attached to the seabed and is not made to move, so it is usually not a vessel. A worker on a fixed platform typically falls under the Outer Continental Shelf Lands Act (OCSLA) and the Longshore Act rather than the Jones Act, though third-party claims against equipment makers or contractors may also be available.
Key takeaways
- A fixed platform is generally not a vessel.
- Workers on it usually fall under OCSLA and the Longshore Act, not the Jones Act.
- OCSLA borrows the adjacent state's law as surrogate federal law.
- Third-party claims against equipment makers or contractors may still apply.
- If you split time on a nearby vessel, your status can be contested.
A structure bolted to the seabed.
A fixed platform is a steel jacket, piled structure, or compliant tower permanently attached to the seabed, standing on the continental shelf and into deeper water. Production operators, maintenance hands, construction crews, and specialty contractors work it. Because it does not move and is not a watercraft, it is not a vessel.
(Floating production units — tension-leg platforms, spars, semi-submersibles, and FPSOs — are a different and more contested category.)
The injuries this work produces.
The platform's hazards are those of a production facility at sea: hydrocarbon releases, fires and explosions, hydrogen-sulfide and chemical exposure, falls from height on the structure, dropped objects, crush, crane and lifting incidents, and confined-space dangers. A large share of serious platform injuries also involve a vessel alongside — a crew boat, a liftboat, a derrick barge — which can open a separate and more valuable claim.
Not a vessel — so it's OCSLA.
Under Herb's Welding, Inc. v. Gray, 470 U.S. 414 (1985), a platform permanently fixed to the seabed on the Outer Continental Shelf is not a vessel — so a fixed-platform worker is generally not a Jones Act seaman.
The claim runs under OCSLA, which borrows adjacent-state law — in Texas, including the Chapter 95 premises shield the defense will try to raise.
If a vessel — a crew boat, a liftboat, a derrick barge alongside — caused the injury, a § 905(b) claim against that vessel may still exist. Finding the vessel is often the door out of the Chapter 95 box.
A maritime worker who is neither a seaman nor LHWCA-covered may still reach unseaworthiness under the Sieracki doctrine.
On a fixed platform, the whole case can come down to whether a vessel was involved — because that's the door out of the Chapter 95 box.

Text (713) 489-2297We've litigated the classification fight.
Doyle Dennis Avery has litigated the platform side of this line directly. In our Chapter 95 platform case, the defense's Chapter 95 gambit on a Gulf structure was defeated; in our foreign-employer jurisdiction case, a ninety-foot fall on a Gulf platform was pursued to recovery against a foreign employer.
On a fixed platform, the most valuable early work is identifying every party — including any vessel involved — whose negligence contributed, because that is what determines whether the case is boxed into Chapter 95 or not.
What the other side will argue — and how it’s met.
A fixed platform is not a vessel, so the defense argues there is no Jones Act and reaches for Chapter 95 to shield the operator. Both moves can be answered.
On a fixed platform the defense reaches for Texas Chapter 95, a statute written to protect property owners from their contractors’ work. It has real exceptions — for the operator’s control over the work and its actual knowledge of the danger — and the firm has defeated exactly that gambit on an OCS structure. See OCSLA & Chapter 95.
The Jones Act uses pure comparative negligence, so a worker’s own fault reduces a recovery but never bars it — and the hazard is usually the company’s. In one case the firm tried, a jury found the injured worker zero percent at fault.
Under the featherweight causation standard, an employer takes its worker as it finds him. Lighting up a silent or prior condition is a compensable injury, not a defense.
Insurers hire investigators to film injured workers for weeks and usually turn up nothing, while the treating physicians and the medical record carry the truth.
A platform case is an OCSLA premises case.
A bottom-fixed platform is governed by OCSLA & Chapter 95, which borrows the law of the adjacent state for premises safety. The defense’s favorite tool is Chapter 95, but its exceptions — the operator’s control over the work and its actual knowledge of the danger — are provable, and the firm has defeated that gambit on an OCS structure. The firm reconstructs the process, height, or equipment failure with a safety expert and pins responsibility on the operator and the contractors who controlled the hazard.
Chapter 95 was written to protect landowners from their contractors — not to let a platform operator walk away from a danger it controlled.
What to protect while it still exists.
The platform’s safety records and the contracts that show who controlled the work are the heart of a Chapter 95 fight.
Safety records, permits, the JSA, and the contracts that define who controlled the work and who knew of the danger are what defeat a Chapter 95 defense. Secure them early.
Tell a supervisor and make sure a written incident report is created. For a serious injury the vessel must also file a Coast Guard marine-casualty report (Form CG‑2692); a missing report is itself evidence of a safety failure.
See a doctor promptly and describe exactly how the injury happened to every provider. An honest, contemporaneous record is the backbone of the case.
You are not required to give the insurer a recorded statement, and early “I’m okay” remarks get used against you. Assume you may be watched, and get advice before signing.
From our cases
Frequently asked questions about a fixed platform injury claims
Is a fixed platform a vessel?
Generally no. A fixed platform is attached to the seabed and is not made to move, so it is usually treated as a fixed structure rather than a vessel.
What law applies to an injury on a fixed platform?
Generally OCSLA, which applies federal law and borrows the adjacent state's law, usually Louisiana or Texas, along with the Longshore Act's compensation scheme.
Can I still be a Jones Act seaman?
Sometimes. If you actually spent substantial time working aboard a vessel rather than the fixed structure, you may still qualify as a seaman. The classification turns on your real assignment.
Can I bring a third-party claim?
Often, yes. Beyond Longshore Act compensation, you may have negligence or product-liability claims against parties who are not your employer, such as equipment manufacturers or other contractors.
What can I recover after an injury on a fixed platform?
Recovery is measured by category rather than a fixed amount: past and future medical care, lost wages and lost earning capacity, pain and suffering, and maintenance and cure for a seaman. The total depends on the facts, so no honest lawyer can promise a number up front.
What is the test for whether something is a vessel?
Courts ask whether the structure is practically capable of being used as a means of transportation on water. Something built to move, such as a drillship or supply vessel, usually qualifies; something fixed to the seabed or permanently moored in place usually does not.
What should you do after an injury on a fixed platform?
Get medical care and make sure the injury is reported in writing. Preserve evidence early, including incident reports, photos, equipment, and witness names, and do not give a recorded statement or sign anything before talking to a lawyer.
