The majority of pipelines are hidden from view and warnings of possible anomalies are not clearly visible. A comprehensive range of assessment techniques are used to assess critical anomalies, including in-line inspections, but how can these issues be accurately located and evaluated in an efficient, timely manner? Reasons for Anomalies According to the Pipeline Association for Public Awareness, “A pipeline anomaly is generally thought of as an imperfection in the wall of the pipe.” Many of these anomalies can result during the manufacturing process and typically don’t affect the performance of the pipeline. However, other more detrimental anomalies that can affect the integrity of the pipeline are be caused by outside elements such as:
• Metal loss defects – occur when the wall of the pipe is thinned due to internal or external corrosion.
• Dents and gouges – usually caused by heavy equipment mining near the pipeline, or by rocks that encounter the pipe wall.
• Cracks – the bond between granules can begin separating due to certain conditions, causing a crack.
Though dents, gouges and cracks are not uncommon, since most pipelines are buried underground, external corrosion is one of the primary threats to the integrity of a pipeline. While pipelines above ground can still be vulnerable to atmospheric deterioration, external corrosion is the predominant cause of metal loss. Regular pipeline inspections and data collection are a necessity to detect this. Helpful Tip: G2-IS provides top quality Inspection Services to ensure your pipeline is maintaining its integrity. Managing Your Data It is essential that Asset Integrity does not become disconnected from the rest of your business. By optimizing and managing operational performance and risk you will be getting the most out of your Data Collection Systems. Effective software systems help by presenting information intuitively and in a way that helps rationalize complex information. An effective Asset Integrity program will provide clear results from the Data Collection Systems. After the calculations are performed, it will lead you to the problem areas, utilize analytical modelling, examine corrosion process models, and provide assessment methods, statistical data mining and analytics. It should also include linear and spatial examination to classify potentially causal relationships between defected anomalies and the pipe environment. Optimizing for the Best Results It is important to get information from these inspections and collections in an efficient and timely matter to make effective real-time decisions. G2-IS has even gone as far to optimize the receivable end of the data collection process by allowing it to be collected on mobile devices. Utilizing global positioning systems and cameras customers are able to capture and integrate comprehensive records at any location efficiently and accurately. Another way to optimize your data collections systems is through web applications, such as pipeline leak detection. Defects caused by corrosion can result in leaks that need to be immediately addressed, but these cannot always be spotted manually and extra assistance finding them within the pipeline is needed. A leak detection web application will maximize leak sensitivity and empower optimal detection of vulnerable areas due to corrosion or stress corrosion cracking that were calculated from the in-line inspection data.
