Abstract
A method for pipeline inspection is provided. The method includes carrying out an inspection run in which a pipeline inspection apparatus travels inside a pipeline, wherein sensors on the apparatus are configured to conduct an in-line inspection of wall material along a length of the pipeline. The method includes initiating a first inspection mode to produce a primary inspection data set, wherein the first inspection mode comprises an inspection of the pipeline wall material upstream and downstream of a location of a dented region in the pipeline, selectively initiating a second inspection mode to produce a secondary inspection data set, wherein the second inspection mode includes an inspection of the pipeline wall material in the dented region in the length of the pipeline, and combining the primary and the secondary inspection data sets to provide a direct assessment for the presence of cracks and/or corrosion in wall material along the pipeline.
