Pipeline Failure Classification - Composite Pipelines

The document discusses the re-classification of 544 composite pipeline failure events from 2000 to 2020, revealing that 440 were caused by excessive unbalanced buckling forces at joints due to cycling exposure to severe slugging or water hammer. It emphasizes the importance of modifying operating practices to reduce these conditions and the prioritization of pressure monitoring devices to manage integrity risks. The report suggests a triage model for classifying pipeline risk and emphasizes that failures are not due to faults in composite pipelines but rather their exposure to extreme operational conditions.
