A unique detection system for tracing leaks from oil and gas pipelines has been developed by Shell at its Stanlow manufacturing complex an Merseyside.
The statistical pipeline leak detection system (SPLD) is a sophisticated new method of spotting leaks using computer calculations of statistical probability. It can detect leaks with a unique degree of speed and accuracy, as well as locating where a leak is occurring. But SPLD can be installed at a fraction of the cost of conventional systems, and run on a standard personal computer.
Shell has granted a licence to a leading pipeline consultancy LIC consult, based at Stockton-on-Tees in Cleveland, to market the system worldwide. It will be marketed under the name "LICSTAT".
The "brain" of the system is a specially-programmed computer package of statistical data, unique to the pipeline it is monitoring. It constantly analyses flow rates and pressures, making hundreds of high-speed calculations per minute to check for unusual trends. The sensitivity of the system...
