A New Phased Array Sensor for Pipeline Inspection – Optimization and Quantitative Performance Evaluation

Baker Hughes
Baker Hughes
The phased array technique allows for a flexible adaption of the ultrasonic inspection techniques for a large range of applications. By using it in the area of pipeline inspection various inspection modes can be performed simultaneously. That was the reason for Baker Hughes (previously PII Pipeline Solutions) to develop an inspection tool based on...

Long Distance Inline Inspection of an Unpiggable Natural Gas Pipeline with Robotic Technology

In-line inspection (ILI) is a pipeline assessment method used by operators to receive a comprehensive integrity assessment of their pipeline. However, ILI may become unfeasible due to factors such as insufficient flow/pressure parameters for propulsion, pipeline features such as valves, back-toback elbows and unbarred tees, as well as the lack of...

Post in-line inspection (ILI) digs are essential tools in the integrity arsenal to validate and verify ILI tool performance and provide data for use in post-ILI integrity assessments. In addition, dig verification can be utilized to validate material properties, increase confidence in feature characterization or even replace previously lost records...

There have been significant advances in magnetic flux leakag e (MFL) in-line inspection (ILI) technologies in recent years. These have led to imp rovements in Probability of Detection (POD), Probability of Ide ntification (POI) and Probability of Sizing (POS). Whilst often the main focus of these advancements is the inspection vehicle itself, the...

A natural gas leakage was detected on the unpiggable high-pressure DN 600 pipeline Kasejovice – Mikulášov in Czech Republic after 50 years of operation. The pipeline was excavated and found to suffer from extensive corrosion; corrosion of a similar extent was also found when another section of the pipeline was excavated on the same location. The...
