Abstract
A contained pipeline and leak detection system includes a primary pipeline section surrounded by a secondary pipeline section and an interstitial space formed between the primary pipeline section and the secondary pipeline section. A pressurized fluid reservoir having a volume of fluid, and in fluid communication with the interstitial space is provided. The fluid in the interstitial space has a pressure greater than the pressure of a fluid inside the primary pipeline section. A sensor detects changes in the volume of fluid in the fluid reservoir, which are indicative of leakage or system malfunction.
