Gradient intersection method

The gradient intersection method provides relatively high accuracy, even on smaller leaks. This technology is based upon the pressure profiles of the two points of inspection (inlet & outlet). This approach is most suitable for detecting gradual or continuous leaks. See more Leak detection for oil & gas continue to evolve, with an increasing number of end user organizations now viewing leak detection systems … See more An increasing number of pipeline operating companies and related stakeholders are beginning to realize that investments in LDS solutions not only will mitigate risk by … See more Leak detection systems are equipped with accurate leak localization technologies to identify leaks or ruptures in different conditions. This enables users to take swift containing … See more ARC (and others) typically segment the LDS market into two major types: external-based LDS and internal-based (software) LDS. See more WebMay 14, 2024 · The gradient projection method is generalized to the case of nonconvex sets of constraints representing the set-theoretic intersection of a smooth surface with a convex closed set. Necessary optimality conditions are studied, and the convergence of the method is analyzed. INTRODUCTION
