Pipeline operators have a number of critical operating and maintenance problems specific to the industry that require careful attention and have an enormous impact on the operator’s bottom line. Leading examples include leak detection, corrosion monitoring, and the surge control of equipment found in harsh, isolated environments. Pipeline operators have adopted available technologies to address these issues, but true solutions have very specific requirements. Because so much of pipeline and pumping systems are existing infrastructure, it is very important that any new technical solutions are suitable for retrofit installations, in addition to new construction. Geographically diverse pipeline installations ranging over hundreds or thousands of kilometers require good telemetry from remote locations.
A recent article in World Pipelines by Emerson’s Denka Wangdi discusses how control, co-ordination, communication, and care of pipeline operations can be improved with the latest edge processing capabilities. Edge gateways transmit field-sourced data up to supervisory systems using the latest protocols for best efficiency. Edge devices include gateway functionality and add the ability to perform information processing and calculations. However, the edge controllers are the most compelling advancement, as they can seamlessly include a comprehensive set of abilities. Edge controllers can be integrated into existing systems to provide new capabilities such as data aggregation and analysis without disrupting proven operation; or, edge controllers can supersede PLCs and RTUs to provide a complete control, monitoring, and analytical solution for new installations.
Of particular interest in this article, Denka goes on to explain how edge technology can be used specifically in leak detection, corrosion detection, and surge control. These details are important information for any pipeline operator.
How do you handle leak detection, corrosion monitoring, and surge control?
