... liners have been introduced, including cement-lined to protect the pipelines from such conditions. Even though cement-liners enhance the reliability of the pipelines, there are still challenges related to inspection. The inspection of cement-lined pipelines is difficult with in-line inspection tools (ILI...

... only rely on cathodic protection (CP) for corrosion protection because it is not practical to repair coating defects. INTRODUCTION Horizontal directional drilling In-line inspection (ILI) Corrosion Coating evaluation Abstract Pipelines installed using horizontal direct drilling (HDD) are normally...

... of In-Line-Inspection (ILI) and field measurements of corroded onshore pipelines. The study addresses the advantages and disadvantages of each analysis approach emphasizing on the ability to capture measurement uncertainties and learnings from trending data. Such learnings can be addressed by a relative...

.... Abstract The Department of Transportation (DOT) pipeline integrity management program (IMP) rule for hazardous liquids pipelines and the proposed rule for gas transmission pipelines require pipeline operators to carry out continual integrity assessments. In-line inspection (ILI) is one of the approved...

...Abstract Pipeline integrity management requires data integration to achieve the best assessment of pipeline condition. In the field of in-line inspection (ILI), data integration can be achieved correlating and merging the analysis results of data sets collected by tools (smart pigs) equipped...
