Inspection of Challenging Pipelines
Lecture
The mechanical integrity of high-pressure pipelines must be ensured. Confirming a maximum allowable operating pressure (MAOP) requires high quality data on the state of the pipe wall.
The online seminar presentation will provide a comprehensive overview of the in-line inspection (ILI) solutions available today with a special focus on challenging pipelines. This includes free-swimming tools as well as tethered and robotic solutions. The presentation will introduce the main non-destructive testing technologies applied in ILI, such as magnetic flux leakage technology and ultrasound.
The difference between traditional high-pressure pipelines and challenging pipelines will be introduced and discussed. Challenging pipelines also referred to as “Difficult To Inspect” pipelines require special consideration regarding inspection from the inside. Typical issues are the design of the pipeline, the operational conditions and the medium in the pipe during the inspection. The presentation will also address the special role of dedicated procedures and the expertise and experience required to perform a successful inspection.
Key Takeaways
- Understand the difference between traditional and challenging pipelines
- Have an overview of available inspection solutions
- Understand the differences and respective strength and weaknesses of free-swimming, tethered and robotic internal inspection tools
