Inspection and Test Plan for Method Statement: Pipeline Pigging, Cleaning and Gauging Prior to Testing/Commissioning

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

Published 12 Sep 2026 Rev. 00 2 views
About this ITP: Defines inspections, tests, hold and witness points for pipeline pigging, cleaning, and gauging. Covers equipment checks, leak tests, pig runs, debris acceptance, and final release.

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 ensure pigging, cleaning, and gauging are executed and verified against project specifications with clear acceptance criteria.

Who uses this inspection and test plan

Contractor QA/QC, Pigging Supervisor, Client Representative, and Third-Party Inspector.

When this ITP is prepared and submitted

From pre-start through final acceptance before hydrotesting or commissioning.

Who receives or approves this ITP

Client/Engineer for review and approval.

Inspection scope

Documentation approvals, equipment calibration, launcher/receiver leak tests, pig selection/dimensions, run monitoring, debris assessment, gauging acceptance, and dossier closeout.

Typical hold, witness, and review points

Leak test of traps (H), Gauging plate measurement (H), Gauging plate receipt inspection (H), Cleaning acceptance (W), Final release (H).

Typical inspection records

ITRs, calibration certs, pig run logs, tracking timestamps, pressure/speed plots, debris logs/photos, gauging inspection reports, release certificate.

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.

Inspection and test plan

Activity Inspection / Test Acceptance Criteria Responsibility Record
Document approvals and pre-start meeting Verify approved Method Statement, ITP, RA, PTW; toolbox attendance. Approvals in place; participants briefed/signed. Contractor QA/QC; Client Rep (W) ITR-01; Attendance Sheet
Launcher/receiver installation check Visual, torque check, interlock function. Correct orientation; bolts torqued; seals intact. QA/QC; Client/TPI (W) ITR-02; Checklist
Instrumentation & PRV calibration Review calibration certs and PRV set sheet. Within calibration; PRV set ≤90% of lowest rating [Verify]. QA/QC (R); Client (W) ITR-03; Cal Certs
Leak test of launcher/receiver (H) Hydro/pneumatic leak test per spec; hold ≥30 min. No visible leaks; stable pressure (within instrument tolerance). QA/QC; Client/TPI (H) ITR-04; Leak Test Report
Tracking system verification Function test signallers and transmitter/locator. Clear detection at all stations. Contractor; Client (W) ITR-05; Function Test
Pig selection and gauging plate sizing Dimensional measurements and OEM verification. Gauge = 95% ID ±0.5 mm; pig OD 0.5–1% over ID [Verify]. Pigging Supervisor; QA/QC; Client (W) ITR-06; Dimensional Report
Pig loading – pre-run checks Launcher depressurized; interlock function; seals greased. Safe loading; closure sealed; no trapped pressure. Pigging Supervisor; Client (W) ITR-07; Launcher Log

Frequently asked questions

Typically the launcher/receiver leak test, gauging plate dimensional check, gauging plate receipt inspection, and final release are hold points.

Debris weight trend logs, photo evidence of foam/effluent, and signed acceptance ITR documenting the criteria are required.
