What PSG covered
The brief
What the client needed
A petrochemical owner experienced a flange-weld failure during a unit turnaround, with consequential downtime and a dispute opening between the owner and the maintenance contractor. PSG was retained to audit the welding program in the affected unit and, subsequently, to serve as the owner-side expert in the contractor dispute.

- 02
Witnessing of repair welds and qualification re-tests for two welders flagged during the audit.
- 03
Expert report written to the form required for the subsequent commercial dispute, with code citations and photographic evidence.
- 04
Deposition testimony delivered the following quarter; the dispute settled before trial.
