Commissioning is where the facility comes alive — with stored energy.
Hook-up and commissioning ties in and energizes piping, electrical, and instrumentation systems for the first time. The transition from construction to live systems brings stored energy, pressure testing, and crowded, high-tempo work.
Bringing systems live.
Hook-up and commissioning connects, tests, and energizes the platform’s piping, electrical, and instrumentation systems for the first time, transitioning the facility from construction to operation through a sequence of tests and start-ups.
Released, shocked, ignited.
Stored-energy release during first energization, pressure-test failures, electrical shock and arc flash, hot-work fires, and struck-by injuries in crowded work areas. Inadequate permit-to-work control and isolation are the recurring failures.
Which law — and who answers.
Offshore construction is vessel-based, contractor-heavy work, so liability spreads across the vessel, the contractors, and the equipment makers.
The construction vessel, derrick barge, or heavy-lift vessel and its crew are controlled by the owner/operator, who answers under the Jones Act and whose unfit vessel or gear can be unseaworthy.
The installation, rigging, and lift companies answer for negligent work and planning; the borrowed-employee doctrine sorts out who controlled the job.
A defective crane, winch, rigging component, or cutting tool supports a products claim against the manufacturer.
On a construction vessel the crew are usually seamen (Jones Act); on a fixed structure the LHWCA/OCSLA and §905(b) vessel negligence apply. The firm preserves whichever route fits (Jones Act vs. workers’ comp).

Text (713) 489-2297We reconstruct the commissioning.
The firm rebuilds the energization sequence, the testing, and the work control, drawing on the release, burn, and shutdown analyses and the borrowed-employee question.
What the other side will argue.
Expect the familiar moves — the claim that a system was isolated rather than energized live — alongside the standard fights over seaman status, comparative fault, and surveillance. The full Construction defense playbook, with how each argument is met, is set out on our construction operations page.
Commissioning runs on procedures and permits.
Commissioning is governed by energization procedures, isolation and lockout, pressure-test plans, and a permit-to-work system — a dense, dated record. The firm reconstructs the work control with a process-safety expert, and the commissioning procedures, the permits, the isolation certificates, and the test records show whether the sequence was safe and who controlled it (borrowed-employee doctrine).
Bringing a system live is a written, permitted sequence — an injury usually marks a step that was skipped.
What to protect first.
For this work the evidence is the commissioning procedures, the permits, the isolation certificates, and the test records — 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 construction 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.
