Building a pressure testing competency program from scratch

A competency program is not a training calendar. It is a statement of what each role must be able to do, and evidence that they can.

Start from roles, not courses

Four roles typically touch a pressure test, and they need different things.

  • The buyer — scopes and accepts. Needs fluency: read a ladder, interpret a window, recognise a defensible acceptance argument.
  • The engineer — designs the test. Needs calculation: Barlow, elevation windows, compliance, pressure-temperature response, inventory.
  • The inspector — witnesses and challenges. Needs both, plus the confidence to stop a job.
  • The technician — executes. Needs procedure, equipment and the failure modes that hurt people.

Define the competencies concretely

“Understands hydrostatic testing” is not a competency; it cannot be assessed. “Can calculate an allowable elevation window for a segment and identify where segment breaks are required” can be.

Write each as something a person can be observed doing, with a stated standard.

Assess against work, not attendance

The strongest evidence is work product: a test ladder the person built, an acceptance argument they wrote, a pressure-volume plot they interpreted correctly under supervision.

Written assessment supports that. Attendance alone supports very little.

On our engineering workshop the asterisked problems of Appendix E are worked through in full, and a sixteen-inch crude oil pipeline is engineered end to end over the day — which produces exactly the kind of work product a competency file needs.

Keep the evidence in a form that survives

Course name, syllabus, date, hours, provider, assessment outcome, and the work product itself. Filed against the individual, not against the project.

People move between projects; the competency file has to follow the person.

Refresh deliberately

Set a refresh interval and hold to it. Regulations change — the spike test requirement arrived with the 2019 gas transmission rule — and a competency assessed against a superseded framework is evidence of the wrong thing.

Scope, stated plainlyA competency program of this kind sits alongside your operator qualification plan. Training supports it; qualification on covered tasks remains your determination under Part 192 Subpart N or Part 195 Subpart G.
Standing noteThis is educational reference material, not engineering advice. Regulations are revised continually; the editions in force at the time of a project govern, and every project requires its own qualified engineering analysis and the operator’s governing specifications.
