... are represented as uniform distributions so that their uncertainty can be incorporated into the probabilistic analysis. As these multipliers represent a means of tuning the semi quantitative model to allow for assessment of a wide range of anomalies, the values currently used should be seen as a starting point...

Electromagnetic acoustic transducer (EMAT) technology has become an increasingly popular crack inspection tool for gas and liquid operators. EMAT overcomes limitations of alternatives such as hydrostatic testing, which can miss...

... ABSTRACT With the increasing complexity of Inline Inspection (ILI) tools and their capability to make multiple data measurements using different inspection technologies, comes the ability to create higher resolution characterization of pipeline anomalies. Because each pipeline has different...

... ABSTRACT An in-line inspection run uncovered a large number of anomalies in one joint of a pipeline. A subsequent investigative excavation revealed external corrosion with fish-bone/flower shaped morphologies. Grinding of the corrosion in the ditch revealed crack-like features in the steel...

... reviewed their existing ILI data at filled and un-filled casings. Data from 43 pipeline inspections were collected and examined for external metal loss anomalies. External metal loss anomalies could include conditions other than external corrosion, including gouges, arc burns, scratches, etc...
