Inspection and Test Plan for Method Statement: Tie‑In Works Inside a Live Oil & Gas Plant (Shutdown, Isolation, SIMOPS, Testing, Reinstatement)

AI-assisted inspection and test plan connected to a method statement, with PDF and Excel export.

Published 10 Nov 2026 Rev. 00 14 views
About this ITP: This ITP defines the hold and witness points for tie-in works in a live oil and gas plant, ensuring compliant isolations, quality welding, safe testing, and proper reinstatement.

More than a static template

Unlike a downloadable Word or PDF template, this ITP is an AI-assisted editable starting point directly connected to its method statement. Every inspection activity, hold point, and acceptance criterion is structured and ready to adapt to your project.

  • AI-assisted customization — Tailor inspection activities and acceptance criteria to your specific project scope.
  • Linked method statement — This ITP is connected to the corresponding method statement describing the work sequence.
  • Multiple export formats — Download as a formatted PDF or editable Excel spreadsheet.
  • Editable starting point, not a final document — Review and verify all content against your project specifications and standards before use.

What you can customize

When you save this ITP to your account, every inspection row becomes editable. You can add, remove, or modify:

  • Inspection activity — Description of what is being inspected.
  • Inspection type — Hold point (H), Witness point (W), Review (R), or Monitor (M).
  • Responsibility — Contractor, subcontractor, engineer, or client.
  • Frequency — How often the inspection occurs.
  • Acceptance criteria — Referenced standard or specification requirement.
  • Records — Forms, test reports, or checklists required as evidence.

Why this ITP is used

To formalize inspection, testing, and approvals needed to assure safety and quality during brownfield tie-ins.

Who uses this inspection and test plan

Contractor QA/QC, Operations/Area Authority, Client/PMC, and third-party inspectors.

When this ITP is prepared and submitted

From pre-shutdown dossier approval through welding, testing, reinstatement, and final handover.

Who receives or approves this ITP

Operations/Client for approval before shutdown.

Inspection scope

Documents, materials, isolations/LOTO, gas tests, fit-up, welding/NDE, testing, drying, coating, reinstatement, and turnover dossier.

Typical hold, witness, and review points

HPs at isolations, pre-break, NDE releases, pre-test, test execution, reinstatement, and final handover; WPs at fit-up, coating, drying.

Typical inspection records

ITRs for each activity, weld maps, NDE reports, test certificates/charts, torque logs, gas test logs, blind/LOTO registers, handover certificates.

Important approval note

This ITP is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all inspection activities, hold points, and acceptance criteria must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.

Always verify acceptance criteria against your applicable drawings, specifications, and regulatory requirements. Hold points must be confirmed with the relevant authority before work proceeds past that point.
