The objective of this project was to develop two robotics platforms, named Explorer II and TIGRE, which equipped with Non-Destructive Evaluation sensors would be able to provide ILI of unpiggable natural gas transmission pipelines. Explorer II is a…
The objective of this project was to implement an eddy current sensor-based method of crack detection using Anisotropic Magneto Resistive sensors aboard the 8in Explorer platform and replicate test results from the earlier phase in a real pipeline…
The objective of this program is to advance the state-of-the-art of electromagnetic induction transducer technology to demonstrate the ability to perform an ultrasonic inspection of steel pipes with sensors separated from the pipe wall by a large…
Pipeline operators apply inspection methods and technologies for the purposes of assessing, or providing confidence in, the operational integrity of pipeline systems. In-line inspection (ILI), hydrostatic testing, and Direct Assessment (DA) methods…
A critical aspect of any pipeline inspection is selecting the correct ILI tool and subsequent vendor, capable of identifying the potential integrity threats a pipeline may contain. Understanding the ILI tool's detection and sizing capabilities is…
The final version, presented by the NDE-3-1 project team as a group review and commentary on the blind trial reports from Transkor and Speir Hunter. this describes the development program on Large Standoff Magnetometry (LSM) techniques claimed to…
Hydrostatic test and In-Line Inspection are the prescribed integrity assessment methods cited in various Codes and Regulations and have been proven to enhance pipeline safety. But a significant number of pipelines across the world remain difficult to…
The NDE-3-2 project seeks to advance the state of the art for integrity assessment of difficult to inspect pipelines by proposing guidance for application of alternate inspection approaches other than…
Pipelines may have number of characteristics that makes pigging impractical or even impossible so those pipelines are classed as unpiggable. A literature review and the definition of "unpiggable" have been reported in another PRCI funded project -…
The work described in this document addresses the first phase of a two-phase project to develop a Base Resource Document (BRD) exploring existing methodologies to monitor and assess the status of unpiggable pipelines, with emphasis on internal…
