ATMOS(TM) Pipe: Statistical Pipeline Leak Detection & Location

ATMOS(TM) Pipe is Statistical Pipeline Leak Detection and location system. ATMOS(TM) Pipe is one of the most tested leak detection systems in the world. It is used by SHELL, BP, EXXONMOBIL, DOW, AIR LIQUIDE and many other pipeline companies. ATMOS(TM) Pipe is a statistical leak
detection system which has been successfully applied to oil, gas, multiphase, chemicals, water and multi-product pipelines both on land and subsea. ATMOS(TM) Pipe has also been used for naval bases, commercial and military airports for tightness monitoring.

ATMOS(TM) Pipe applies the Sequential Probability Ratio Test to the corrected flow balance system after a comprehensive data validation process. The system does not use complicated hydraulic models to simulate a pipeline. Instead, it continuously calculates the statistical probability of a leak based on fluid flow and pressure measured at the inlets and outlets of a pipeline. Depending on the control and
operation of a pipeline, pattem recognition techniques are used to identify changes in the relationship between the Pipeline pressure and flow when a leak occurs.

ATMOS(TM) Pipe has detected more than 400 real leaks in gas and liquid pipelines. In gas pipelines ATMOS(TM) Pipe has detected leaks as small as 1 % of throughput. The ability of ATMOS(TM) Pipe to detect leaks under transient conditions without false alarms makes it unique among all leak detection technologies. As soon as a leak waming is generated, ATMOS(TM) Pipe provides the leak-rate and location estimates.
