PIPELINE FAILURE RATES-1: Method helps pool multisource data

The statistical uncertainty in the estimation of the average failure rate of a group of pipelines decreases as failures, km-years, or both increase. This fact has led to the tendency in pipeline reliability analyses to increase the number of km-years from which the failure data are pooled, reducing statistical uncertainty associated with estimating the failure rate.This approach, however, is only valid if the uncertainty arising from the physical, environmental, and maintenance differences between pipeline systems is negligible.1Oil and gas pipeline systems encompass many failure mechanisms, the most common being corrosion metal loss, third-party damage, geotechnical hazard, hydrogen-assi...
