Integrity Assessments

Aging infrastructure, cyclic conditions, and throughput demand are all indicators that a system’s integrity could be compromised.

NDT Global has the most advanced set of tools in the industry to assess potential compromises. Our team of pipeline integrity engineers are also certified data analysts, making them uniquely qualified to produce actionable insights that operators can rely on to make the best integrity management decisions. These assessments include the following:

Cracks in Dents Diagnosis: Best practices consider dents with any stress riser as an immediate threat to a pipeline. We've addressed this by developing a diagnosis methodology to assess cracks interacting with dents with industry leading PODd.

Finite Element Analysis (FEA): In some instances, anomalies in pipelines present highly complex morphologies and/or combined stresses, posing a challenge for conventional assessment methods. These challenges can make predicting failure pressures and remaining pipeline life inaccurate and unreliable. Added to this, simplified models can yield conservative results leading to unnecessary repairs. In cases like this, finite element analysis utilizing NDT Global’s unparalleled data is the closest thing to actually observing defect behaviors.

Fitness for Purpose Assessment : NDT Global’s Fitness for Purpose (FFP) assessment is one of the most comprehensive that we offer. Depending on an asset’s history, we assemble a best-in-class inspection solution that gathers the most robust set of feature data in the industry. Our team of pipeline integrity engineers then analyze this data and provide the detailed insights required to determine FFP and make informed decisions about integrity management plans.

Immediate Integrity Assessment : When you receive an ILI report that indicates, for example, that feature density is higher than expected or that there is some other imminent risk, our immediate integrity assessment is an ideal choice. We look at the existing inline inspection analysis, historical inspection data (if available), and make an informed determination of the pipeline’s integrity. With these insights in hand, operators can continue their business while planning for mitigation efforts to avoid disruption.

Future Integrity and Fatigue Life Assessment : Our future integrity and fatigue life analyses are designed to determine the remaining life of your pipeline and deliver insights that will allow you to extend the asset lifecycle.

Feature Growth Assessment: Predicting feature growth is among the most critical insights required to ensure the safe and profitable operation of a pipeline. NDT Global capitalizes on the high accuracy of our data to achieve the most realistic feature growth predictions. Over time, these signal-on-signal analyses provide the insights needed to maximize asset lifecycle, safety, and profitability.

Pipeline Movement Assessment: Pipelines are designed, to within millimeter levels of accuracy, to make sure they operate efficiently, safely, and profitably. Landslide, earthquakes, and erosions put all of those goals in jeopardy. In a single inspection, our ultrasonic tool, coupled with an INS module, delivers the information needed to identify where movement is happening and what incremental strain and risk it’s introducing. Our run-on-run Pipeline Movement Assessments provide ongoing insights about how that movement is correlated to bending strain, circumferential cracks, and other asset threats.

Dent Strain Assessment: In and of themselves deformations can cause throughput challenges. Left unattended, they can lead to cracks and other threats in your pipeline, disrupting service, affecting the environment, and reducing asset profitability. Our dent strain assessment was designed to identify these threats and then – through the analyses by our team of experts – give you the information you need to address the most critical risks and defer remediation for those that are nowhere near criticality.

Dent Profile Characterization: Of all the threats facing a pipeline’s operation, dents have the potential to be the most injurious. They can be harmful on their own but can be even more injurious if they are adjacent to other features like metal loss, cracks, or other defects. Dent Profile Characterization plays an important role in these dent observation measures because the potential threats that dents present are based on a wide array of factors.
