The course will cover methods available to assess the significance of defects detected in onshore and offshore pipelines. It will introduce simple analytical methods used to assess internal and external corrosion, dents and gouges, cracks (e.g. SCC), weld defects, and fatigue.

PIGGING AND IN-LINE INSPECTION COURSE

Pipelines provide one, if not the, safest and most economic means to transport large quantities of oil and gas. Great care is taken in designing, constructing and maintaining pipeline. However, just as with any other technical component, pipelines can degrade with time. Inspection is an important part of the maintenance process. In­line inspection tools, or ILI pigs, can be used to inspect a pipeline from the inside. They collect geometric data on any flaws present and this data can be used for the integrity assessment of the line inspected.

Course notes:

All delegates will receive a detailed set of lecture notes and the newly published reference book Pipeline Pigging & Integrity Technology 3 rd edition (£80 €115 value).

WHO SHOULD ATTEND:

Pipeline engineers, technicians and compliance personnel from operators. Engineering consultants active in the field of NDT and Integrity Assessment. Personnel from regulatory authorities or certification bodies involved with pipeline inspection and assessment.
