This paper describes the work that was undertaken to re-qualify the Cactus-Guadalajara LPG pipeline for a higher MAOP without taking the pipeline out of service for a hydrostatic test. It demonstrates how geo-positioning technology, high-resolution in-line inspection, and data management systems can be successfully utilized for such project, even when the record-keeping associated with previous pipeline repairs has been deficient. By establishing a geo-referenced pipeline asset management system that integrates physical asset description, operational data, internal inspection and pipeline repair data, a sound foundation has been created for the future integrity management of this pipeline.
