In-Service Inspection (Oil, Gas & Chemical Plants)

We keep operating assets safe and compliant by spotting corrosion, wear and damage before they cause failures. Our inspectors run on-stream and turnaround checks with targeted NDT (visual, UT thickness, PMI, MT/PT/RT). You get remaining-life calculations, RBI-aligned intervals, and a clear report with grades, photos, and next steps for repair or monitoring.

  • On-stream & turnaround inspections for vessels, piping, tanks, exchangers

  • Targeted NDT: visual, UT thickness/mapping, PMI, hardness, MT/PT/RT

  • Remaining life, RBI-aligned intervals, clear defect grades + photo log + actions

The mentioned activity will be linked to our engineering capabilities for FFS, ECA, RBI, and Asset integrity management programs for life extension and plant reliability.

Visual Inspection

Basic examination of equipment surfaces to identify obvious signs of wear, corrosion, or damage according to API 510, 570, 653, and other relevant inspection codes

Includes methods such as ultrasonic testing (UT), radiographic testing (RT), magnetic particle testing (MT), and dye penetrant testing (PT) to detect internal and surface defects without damaging the equipment.

Techniques such as corrosion coupons, electrical resistance probes, and corrosion rate meters to measure and monitor the rate of corrosion.

Ultrasonic thickness gauging to measure the remaining wall thickness of vessels and piping.

Monitoring and analyzing vibrations in rotating equipment to detect imbalance, misalignment, or bearing wear.

Using infrared cameras to detect heat anomalies that indicate issues like insulation failure or hot spots.

Includes methods such as phased array ultrasonic testing (PAUT), digital profile radiographic testing, magnetic flux leakage (MFL), time of flight diffraction (ToFD), C-Scan corrosion mapping, …
