This report describes the results of a research project on the reliability-based optimization of pipeline integrity maintenance activities. The objective of the project was to develop models to quantify the effect of different maintenance activities on the structural reliability of pipelines and to demonstrate how the results of these models can be used in a reliability-based framework to develop optimal integrity maintenance plans. The approaches developed can be used to prioritize different pipeline segments for maintenance and to select the optimal combination of integrity maintenance actions...
This report describes the results of a research project on the reliability-based optimization of pipeline integrity maintenance activities. The objective of the project was to develop models to quantify the effect of different maintenance activities on the structural reliability of pipelines and to demonstrate how the results of these models can be used in a reliability-based framework to develop optimal integrity maintenance plans. The approaches developed can be used to prioritize different pipeline segments for maintenance and to select the optimal combination of integrity maintenance actions for high priority segments. The maintenance decisions considered for a given pipeline segment include the maintenance method, the time interval between maintenance events, and the repair criteria for damage detected by inspection.
