A compliant tower flexes with the sea — but it’s fixed to the seabed, so it’s OCSLA.
A compliant tower is a slender platform anchored to the seabed and engineered to sway with waves and wind instead of resisting them. It moves a little, but it doesn’t travel — it is a fixed structure, which puts the case under OCSLA rather than the Jones Act.
Is a compliant tower a vessel, and what law covers an injury on it?
Generally no. A compliant tower flexes with the sea but is anchored to the seabed and not made to move, so it is usually not a vessel. A worker on a compliant tower 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 compliant tower 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 flexible tower, fixed in place.
A compliant tower is a tall, slender, fixed offshore platform anchored to the seabed and designed to flex and sway with waves, wind, and current rather than stand rigid against them. That compliance lets it work in deeper water than a conventional jacket platform. Despite the movement, it is permanently fixed in place and is not a watercraft.
(Floating production units — TLPs, spars, semi-submersibles, and FPSOs — are a different and more contested category.)
The injuries this work produces.
A compliant tower'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. As with any fixed platform, a large share of serious injuries also involve a vessel alongside — a crew boat, a liftboat, a derrick barge — which can open a separate and more valuable claim.
Fixed to the seabed — 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-structure 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.
A compliant tower sways, but it doesn't travel — so like any fixed platform, the case turns on OCSLA and whether a vessel was involved.

Text (713) 489-2297We've litigated the classification fight.
Doyle Dennis Avery tries the cases where classification is the battle. 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 structure, 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 compliant tower is a fixed structure for legal purposes, so the defense argues no Jones Act and invokes Chapter 95 — the same playbook as any platform.
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 compliant-tower case is an OCSLA premises case.
A compliant tower flexes with the sea but is anchored to the bottom, so it is treated like a fixed platform under OCSLA & Chapter 95. The contest is usually Chapter 95 and who controlled the work, and the firm has beaten that defense on an OCS structure by proving the operator’s control and actual knowledge. The firm reconstructs the production, height, or equipment failure with a safety expert and holds the operator and the responsible contractors to account.
A tower that sways with the waves is still a workplace someone was responsible for keeping safe.
What to protect while it still exists.
The tower’s safety records and the work contracts decide the Chapter 95 fight, and they are controlled by the operator.
Permits, safety records, the JSA, and the contracts showing control of the work and knowledge of the danger are what answer a Chapter 95 defense. Demand preservation.
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.

Frequently asked questions about a compliant tower injury claims
Is a compliant tower a vessel?
Generally no. A compliant tower flexes with the sea but is anchored to the seabed and 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 compliant tower?
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 compliant tower?
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 compliant tower?
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.

- You’re not sure your case is “big enough” — that’s exactly what a free review is for.
What you were working on shapes your claim.
