Abstract Evaluating the effectiveness of a CPM implementation via leak testing is paramount to confirm that the performance of the CPM system is acceptable based on a pipeline company's risk profile for detecting leaks. However, leak testing of a CPM system is challenging due to the complexity...

ABSTRACT: It is a very well established belief that a leak detection system based on real time transient modeling will perform independently of the pipeline control modes (pumps, regulators, etc.). These control modes are typically not very flexible and often cannot be changed to achieve the...
