As safety is
very important, the risk of pipeline leakage must be
mitigated to avoid loss of life, costly shutdowns, environmental and
property damage. In this project, we have developed reliable and
computationally efficient integrated leak detection and localization
(iLDL) system for gas transmission pipelines, with short detection
delay, fast and accurate leak localization and accurate leak rate
quantification. The iLDL system combines acoustic method and
mass/volume balance method to enhance the system’s performance.
We were able to
detect and locate leaks with leak localisation error of less than 1 %
for a high pressure pipeline of 600 m. The iLDL system was also
proven to be tested with operating data obtained from a “live”
underground gas pipeline.
The iLDL system is
beneficial and could be a solution for the pipeline operating
companies in all industries: oil, gas, chemical, aviation, mining and
water.
