Cementing is high-pressure, high-energy work — and a pressure failure is violent.
Pumping cement to secure casing means high-pressure pumps, treating iron, hoses, and chemicals. A line that parts or a connection that fails under pressure releases enormous energy.
Securing the casing.
Cementing pumps a cement slurry down the casing and into the annulus to seal the well, using high-pressure pumps, treating iron, and hoses, often run by a service company alongside the drilling crew.
Pressure, projectiles, chemicals.
A parted line or failed connection under pressure becomes a projectile; hoses whip; and cement and additives cause chemical burns and respiratory injury. The energy involved makes these injuries catastrophic.
Which law — and who answers.
Drilling crews are seamen, so the claim runs under the Jones Act and the general maritime law.
The contractor that owns the rig and crews the floor answers for unsafe procedure and equipment under the Jones Act.
The operator’s drilling program and company representative on board can carry responsibility for the decisions that set the pace.
A defective top drive, iron roughneck, tong, or elevator — or a service contractor’s negligence — supports a separate claim, and an unfit one can render the rig unseaworthy.
The floor crew are crew of a vessel or MODU, so the Jones Act and unseaworthy doctrine apply — not a landside comp schedule.

Text (713) 489-2297We reconstruct the pressure path.
The firm rebuilds the pump pressures, the iron, and the connections, drawing on the release and chemical-exposure analyses and the borrowed-employee question among the service companies.
What the other side will argue.
Expect the familiar moves — the claim that the treating iron was rated rather than overdue for inspection — alongside the standard fights over seaman status, comparative fault, and surveillance. The full Drilling defense playbook, with how each argument is met, is set out on our drilling operations page.
Pressure work leaves a record.
Treating iron is rated, inspected, and pressure-tested, so a failure under pressure has a paper trail. The firm reconstructs the pumping operation and the iron’s condition with a marine-safety and pressure expert, and the job tickets, the pressure records, and the maintenance history show what failed and who knew. The service-company relationships are sorted out under the borrowed-employee doctrine.
Treating iron is rated and tested for a reason — a failure under pressure is almost never a surprise to everyone.
What to protect first.
For this work the evidence is the job tickets, the pressure and pump records, and the iron-inspection logs — held by the company and routinely overwritten, so demand preservation in writing before it is lost, and get prompt medical care. The full first-days checklist is on our drilling operations page.

What happens when you text us
Tell us what happened — in your own words, as much or as little as you want.
We review it free. You learn whether maritime law protects you and what your options actually are.
You decide. Nothing is filed, and no one contacts your employer, unless you choose to move forward.
Your conversation with us is confidential. There is no fee unless we win. Hablamos español.
Reach out even if…
- You think the accident was partly your fault — under the Jones Act, your own fault reduces a recovery but does not bar it.
- You already gave a statement or signed something — a release signed under pressure can be challenged.
- You still work for the company — talking to a lawyer is confidential, and retaliation for pursuing a claim can itself be actionable.
- You’re not sure your case is “big enough” — that’s exactly what a free review is for.
Catastrophic offshore injury? The investigation can’t wait.
Equipment gets repaired, records get revised, and witnesses rotate off the rig. Doyle Dennis Avery LLP moves quickly to preserve the evidence and identify every responsible party. A case review costs nothing, there is no obligation, and your employer will not know you contacted us.
