Method gives realistic analysis of leak-detection systems

03/21/2005
The pipeline and leak-detection industries do not currently have a consistent, coherent, and complete means of assessing leak-detection system (LDS) performance. Probabilistic performance maps, however, may help overcome present LDS shortcomings.Probabilistic performance maps can be developed in an automated fashion for a pipeline LDS by imposing a large range of artificial leaks on sets of recorded realtime data and then using the modified data to drive the system in an off-line mode.The resulting maps provide a more realistic assessment of leak-detection performance than more commonly utilized single-parameter LDS leak-sensitivity benchmarks because they inherently address uncertainties...
