Inspection & Integrity
Internal & External Inspection Services
Comprehensive NDT and visual inspection of surface and subsurface equipment — identifying defects before they become failures, and keeping assets compliant and productive.
Service Overview
Comprehensive Asset Inspection Services
Sequential International provides detailed inspection services for oilfield equipment, pipelines, pressure vessels, and structural components. Our CSWIP and PCN-certified inspectors deploy modern NDT techniques to detect corrosion, cracking, and other defects that could compromise asset integrity.
Inspections are fully documented and reported to client and regulatory standards — giving operators the data they need to make informed integrity management decisions.
“An undetected defect in oilfield equipment is a risk to lives, the environment, and production. Our inspectors find what others miss.”
What We Deliver
Scope of Work
Ultrasonic Testing (UT)
Wall thickness measurement, corrosion mapping, and weld inspection using contact and phased array UT.
Magnetic Particle Inspection
Surface and near-surface crack detection on ferromagnetic components using MPI techniques.
Dye Penetrant Inspection
Surface-breaking defect detection on non-magnetic components using liquid penetrant testing.
Visual Inspection
Detailed visual inspection of equipment condition, coating integrity, and structural soundness.
Corrosion Mapping
Automated and manual corrosion mapping of pipelines, vessels, and structures for integrity trending.
Weld Inspection
Pre- and post-weld inspection including radiographic and ultrasonic testing of weld seams.
How We Work
Our Service Process
Scope & Access Planning
Review of inspection scope, equipment history, and access requirements.
Surface Preparation
Coating removal or cleaning as required to expose the inspection surface.
NDT Execution
Certified inspector applies selected NDT technique with calibrated equipment.
Report & Recommendations
Detailed inspection report with findings, fitness-for-service assessment, and maintenance recommendations.
Why Choose Us
Key Benefits
Defect Early Detection
Detecting corrosion and cracks early prevents catastrophic failures and costly unplanned shutdowns.
CSWIP / PCN Certified
All NDT inspectors hold recognised industry certifications — results are credible and defensible.
Calibrated Equipment
All NDT equipment is calibrated and certified — results are accurate and traceable.
Regulatory Acceptance
Inspection reports prepared and formatted for NUPRC, DPR, and insurance company acceptance.
Fitness-for-Service Assessment
Engineering fitness-for-service assessment to determine remaining life and continued operation acceptance.
Corrosion Trending
Repeat inspection programmes enable corrosion rate calculation and life prediction.
Inspection work frequently involves work at height, confined space entry, and use of radiation sources. Sequential International applies strict controls for all hazards associated with inspection activities, including radiation safety management for radiographic testing operations.
