Pipeline Integrity Services

Pig Tracking / Run Support

We provide full-service tracking for cleaning tools, maintenance pigs, and intelligent inspection (ILI) tools.

Services include:

• Monitoring tool arrival and departure
• Noise, magnet, and vibration detection
• Recording passage times and signatures
• Real-time communication with operators and control rooms
• GPS documentation of all marker points

Our process ensures operators receive a full, traceable run record from launch to receipt.

AGM Surveys (Above-Ground Marker Surveys)

We place and monitor AGMs to capture tool passage signatures and verify position.

Deliverables include:

• AGM placement and documentation
• GPS-located marker coordinates
• Raw signal verification
• Signature confirmation for alignment with ILI vendor data
• Complete AGM survey reports

AGM data is delivered in formats suitable for integrity engineering teams.

Anomaly Response & Dig Staking

Once ILI data is received, our teams identify, stake, and document anomaly locations with accuracy.

We provide:

• Staking based on stationing, alignment sheets, and GPS data
• Verification of dig locations
• Depth of cover measurements
• Documentation for repair crews and NDE vendors
• Coordination support during excavation activities

We ensure each dig site is properly identified, recorded, and ready for remediation activities.

Depth of Cover Surveys

We perform depth-of-cover measurements using approved tools and procedures to verify adequate cover over transmission and gathering lines.

DOC services include:

• GPS-located measurement points
• Trench line confirmation
• Surface condition observations
• Deliverables in operator-required formats (CSV, Excel, GIS)

All DOC work aligns with operator specifications and regulatory expectations.

Integrity Dig Oversight & Inspection

Our integrity inspectors represent the operator during anomaly digs and repair work.

Activities include:

• Safety oversight and participation in JSAs
• Verification of dig staking and location accuracy
• Inspection of exposed pipe for coating condition and anomalies
• Coordination of NDE as required
• Monitoring installation of sleeves and repairs
• Inspection of coating reapplication
• Documentation of backfill and right-of-way restoration
• Final reporting with photos and structured data

We ensure the repair process follows operator standards and all required documentation is completed correctly.

Regulatory-Focused Deliverables

We support operator compliance with:

• 49 CFR Part 192
• 49 CFR Part 195
• PHMSA integrity management rules
• Operator-specific integrity procedures

Deliverables include:

• GPS data
• Photo documentation
• Dig site reports
• Repair documentation
• AGM logs
• Depth-of-cover records
• Daily inspection reports
• Final integrity dig summaries

All data can be delivered as PDFs, Excel files, GIS files, or in operator-specific templates.
