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