Pipeline Inspection
Pipeline Inspection
Pipeline Inspection is critical to ensuring the safe, reliable, and efficient transport of oil, gas, and process fluids across onshore and offshore facilities. At Assessfie, our pipeline inspection services are designed to detect corrosion, wall thinning, cracking, weld defects, and mechanical damage throughout the pipeline lifecycle. By combining conventional, advanced, and robotic NDT techniques, we help operators reduce failures, maintain compliance, and extend asset life.
How Pipeline Inspection Works
- Pipelines are assessed using suitable NDT techniques based on diameter, material, location, and service conditions.
- Inspection methods are applied externally, internally, or remotely depending on accessibility.
- Data is collected to identify corrosion, defects, or anomalies affecting integrity.
- Certified inspectors analyze results and provide actionable reports with recommendations for repair, monitoring, or continued operation.
Technologies & Techniques We Use
- Ultrasonic Testing (UT) & Corrosion Mapping
- Phased Array UT (PAUT) & TOFD for Weld Inspection
- Long Range Ultrasonic Testing (LRUT)
- Pulse Eddy Current Testing (PECT)
- Magnetic Particle & Visual Testing
- Internal Robotic Visual & UT Inspection
- Digital / Computed Radiography
- In-service and shutdown inspection solutions
Onshore Pipeline Inspection
Our onshore pipeline inspection services support pipelines running across plants, terminals, refineries, and cross-country routes. We help identify integrity threats while minimizing excavation and operational disruption.
Typical onshore applications include:
- Cross-country pipelines
- Buried and above-ground pipelines
- Pipe racks and road/rail crossings
- Insulated and coated pipelines
- In-service integrity assessments
Offshore Pipeline Inspection
Offshore pipelines operate in highly corrosive and dynamic environments. Our offshore inspection solutions are designed to ensure safety and compliance in marine conditions.
Typical offshore applications include:
- Topsides piping systems
- Subsea and near-shore pipelines
- Risers and splash zone pipelines
- FPSO and offshore platform piping
- Marine and coastal infrastructure
Pipeline Inspection Applications in the Oil & Gas Industry
Pipeline inspection plays a key role across upstream, midstream, and downstream operations. Common applications include:
- Pipeline Weld Integrity — Girth welds, tie-ins, and repair welds
- Corrosion & Erosion Monitoring — Wall loss detection and trending
- Integrity Management Programs — Risk-based inspection planning
- Leak Prevention & Safety Assurance — Early detection of failure mechanisms
- Regulatory Compliance — Meeting statutory and operational requirements
- Maintenance & Shutdown Support — Pre- and post-repair inspection
