Topic: Advances in Comprehensive Integrity Assessment of Buried Pipelines with Non-Contact Magnetic Gradient Tomography Method (MTM-G).
Synopsis:
It is becoming increasingly clear that relying on only a single tool out of the integrity toolbox is not an effective means of managing risk exposure. Direct Assessment (DA), Inline Inspection (ILI) and hydrostatic testing (HT) approved pipeline integrity assessment techniques. These pipeline integrity techniques have their strengths and weaknesses but an integrated approach that would combine ILI and DA techniques would provide comprehensive pipeline integrity management program for pipeline operators. This submission presents case studies of MTM-G and ILI and how both are combined to help address areas of concern on piggable pipelines. The results from this case studies are good news for unpiggable pipeline operators that have been looking for ways to identify areas of metal loss without having to expose the buried pipeline.
