Field Testing of Negative-Wave Leak Detection Systems

Abstract: The pipeline industry is improving its ability to detect and locate leaks through emerging technologies. There has been a variety of research in recent years aimed at further development of sensor-based technologies for leak detection. A key obstacle to retrofitting existing pipelines with leak detection technologies is the cost and risk of installing hardware, particularly those sensors that require excavation near the pipe. There are many advantages to employing leak detection systems that can leverage exist… Show more

“…The algorithms filter out noises, arrange the analogue pressure data into a detailed 3-dimensional map that allows the system to clearly differentiate true leak/theft events from the pressure changes caused by transient operations. This system has been subjected to hundreds of tests with both leaks and thefts, including one facilitated by PRCI (Pipeline Research Council International) [5]. Some very impressive results have been generated in both gas and liquid pipelines.…”

“…Although leak detection and integrity management have brought much attention to cross country pipelines [1], [2], [3], [4], [7], [8], [10], the application to offshore pipelines is relatively limited [5], [6]. However most of the leak detection technologies described in API 1130 [9] are feasible for offshore pipelines.…”
