This report concerns an assessment of numerical anomalies found whilst undertaking reliability analyses for a case study as part of a Research Project for the HSE Competition of Ideas. The case study was taken from a report produced by the then BG Technology (now Advantica Technologies Limited), and was an example of the application of limit state, reliability and risk-based design techniques to the uprating of onshore pipelines. Probabilistic arguments had been used to demonstrate that the increase in risk as a result of the higher operating pressures in the pipelines was negligible.
