Oil rigs in the Gulf of Mexico range from platforms fixed to the seabed to drillships that move under their own power. Federal offshore production there averaged 1.9 million barrels of crude oil a day in 2025, according to the U.S. Energy Information Administration, which now calls the area the Gulf of America. The work carries serious risks from fire, falls, and heavy equipment. For an injured worker, the type of rig and where it sits also decide which law covers the claim.
Oil platforms in the Gulf of Mexico fall into four broad types:
| Rig type | How it sits | Can it count as a vessel? |
| Fixed platform | Attached to the seabed | Generally no |
| Jack-up rig | Legs lowered to the seafloor, moved between sites | Can be |
| Semi-submersible | Floats on pontoons, moored or held in place | Can be |
| Drillship | A ship that moves under its own power | Usually |
The vessel question matters because seamen, workers whose jobs tie them to a vessel, have different legal rights than platform workers. In Stewart v. Dutra Construction Co., the Supreme Court held that a vessel is any watercraft practically capable of maritime transportation. A watercraft that has been permanently moored, or otherwise made practically incapable of moving, does not qualify.
Gulf of Mexico oil rig locations fall into two zones. Close to shore, rigs sit in state waters, and off Texas that boundary runs three marine leagues, about 10 miles, offshore, according to the Texas General Land Office.
Beyond that line is the outer Continental Shelf, the federal seabed. The Outer Continental Shelf Lands Act extends federal law to that seabed, to artificial islands, and to installations attached to it for producing oil and gas. For a worker, the rig’s location is one of the first facts that shapes which rules apply.
Offshore work combines pressurized oil and gas, heavy machinery, and work at height far from a hospital. The hazards that hurt rig workers include:
Fire remains a top concern in federal data. The Bureau of Safety and Environmental Enforcement reported that the fire incident rate in outer Continental Shelf operations has risen since 2020, partly because a 2019 agency notice clarified which fires must be reported, and that three workers died in offshore operations there in 2024. The Gulf has also seen how bad a rig fire can get. In April 2010, the explosion and fire on the Deepwater Horizon rig killed 11 workers about 50 miles southeast of Venice, Louisiana, according to the U.S. Chemical Safety Board.
Three main legal paths apply to injuries on Gulf rigs:
Not everyone who works on a rig is a seaman. In Chandris, Inc. v. Latsis, the Supreme Court’s majority held that a seaman’s duties must contribute to the function or mission of a vessel, and that the worker’s connection to a vessel in navigation must be substantial in both duration and nature. The Court added that a worker who spends less than about 30% of their time in the service of a vessel should not qualify, while calling that figure no more than a guideline.
When a worker dies on the high seas more than 3 nautical miles from shore, the Death on the High Seas Act lets the personal representative bring an admiralty claim, a case under federal maritime law, for the spouse, parents, children, or dependent relatives. Because these paths overlap at the edges, two workers hurt the same way on different rigs can end up with very different claims.
Each legal path has its own filing deadline:
| Type of claim | Deadline | Authority |
| Maritime injury or death claim, including a Jones Act claim | 3 years after the claim arose | 46 U.S.C. § 30106 |
| Longshore Act compensation claim | 1 year after the injury or death, starting once the worker knew or should have known it was work related | 33 U.S.C. § 913 |
| Texas personal injury or wrongful death suit, where Texas law applies | 2 years after the claim accrues (legally arises) | Tex. Civ. Prac. & Rem. Code § 16.003 |
Each claim runs on its own clock, so the shortest deadline that fits the facts sets the practical limit. Identifying the right legal path early keeps more options open for an injured worker or a grieving family.
An offshore injury can leave you far from home, out of work, and unsure which law even applies.
