In-line Inspection (ILI)

In-line inspection can be performed for piggable and “difficult to inspect”/ non-piggable pipelines.
Onshore and Offshore trunk pipelines for most accurate Ultrasonic Inline Inspection for most
accurate metal loss and crack detection (UM, UC, UCC). AE has performed 50+ ILI jobs for their
Pipeline Owner clients. Some of the specialized ILI technologies provided by AE are:

Ultrasonic In-line Inspection - Detection of corrosion features with a “direct wall thickness measurement” for anomaly diameter of 5 mm (0.2 in) reaching a probability of detection level (POD) of > 90%. Classification and depth sizing is provided for all metal loss defects from 5 mm (0.19 in) on wards. High-resolution river bottom profiles enable accurate defect assessments along with pitting configuration ILI tools.
Ultrasonic Crack Detection In-Line Inspection - Crack inspection robots use 45˚ shear wave, a methodology employed industry-wide. Due to a so-called corner reflection produced by this method, minor cracks anywhere from approximately 1 mm (0.04 in) onwards give strong reflections for analysis.Ultrasonic crack inspection enables early detection and sizing of cracks and crack-like irregularities. Such accurate information allows operators to take necessary measures to help avoid pipeline failures.

Non-Piggable or “Difficult to inspect” pipeline ILI by utilizing InVista^TM - Ultrasonic In-line Inspection tool. Effective pipeline integrity management can be problematic for the large number of pipelines that were not designed for in-line inspection (traditionally non-piggable pipelines).
We understand the complexities involved with this challenging segment and offer a comprehensive pipeline integrity management solution – the InVista™ ultrasonic (UT) in-line inspection tool from 2” diameter and above pipelines. Lightweight and compact, the InVista™ tool can be launched by hand and is ideal for space-constrained environments.

AE has performed India’s 1st City Gas non-piggable pipeline ILI and more.

Gas Pipeline ILI by ART Scan^TM - The ART Scan^TM internal pipeline inspection solution performs “direct wall-thickness” measurements in high-pressure gas pipelines, giving the operator a more accurate depth measurement and providing them with the information required to carry out their integrity assessments with greater levels of confidence.
