What is the Outer Continental Shelf Lands Act, and what law governs platform injuries?

Federal islands off the Texas coast

Beyond state waters, the seabed of the Outer Continental Shelf belongs to federal jurisdiction, and Congress solved the problem of law on the structures built there with a borrowing statute: the platforms are treated like federal enclaves, federal law controls, and where federal law is silent, the adjacent state's law, for most Gulf platforms off this coast, Texas or Louisiana law, applies as surrogate federal law. That elegant-sounding arrangement has hard edges in practice, because which state is adjacent, and which body of law supplies the rule for damages, limitations, or indemnity, can swing outcomes dramatically, and the choice-of-law fight in an OCSLA case is strategy, not formality.

The compensation layer, and the workers it covers

For the people extracting the resources, OCSLA extends the Longshore and Harbor Workers' Compensation Act's benefit scheme to injuries occurring on the Shelf: the no-fault disability payments, medical care, and death benefits described on the Longshore page, administered through the same federal system. That is the floor, not the ceiling. The third-party claims that turn a benefits file into a recovery survive alongside, the negligent contractor who ran the crane, the defective equipment's manufacturer, and, critically, any vessel whose negligence caused the harm, because the crew boats, supply vessels, and lift boats serving a platform are vessels in the fullest legal sense even though the platform is not.

Platform or vessel: the question that picks your remedies

Courts settled long ago that a fixed platform is not a vessel, so its workers are generally not seamen, no Jones Act, no unseaworthiness, but the modern Gulf blurs the categories on purpose: jack-up rigs, semisubmersibles, and drillships are vessels, workers rotate between structures, and a welder's month can span three legal universes. The classification analysis, covered on the seaman-status page, runs on dispatch records and time math, and it is worth running carefully in every platform case, because the difference between Longshore benefits and a Jones Act jury is the difference between a schedule and a verdict. Employers know this, which is why their paperwork tends to reach the classification conclusion cheapest for them.

Houston's cases, wherever the water is

The Shelf's workforce lives here, its operators are headquartered here, and its cases are tried here. Silver Key Law works platform injuries with the borrowed-law and classification questions at the front of the analysis, where they belong, and the consultation for any offshore worker is free.
