Corroded pipelines

Course description

This is a 2-day course. It provides insight in how to assess pipeline integrity with respect to corrosion based on the principles described in DNV-RP-F101 Corroded pipelines.

Learning objective

Upon completion of this course the delegates have obtained an overview of the most important technology concepts, systems and terminology in the following areas:

• Be able to use DNV-RP-F101 to assess corroded pipelines subjected to internal pressure (single defects, interacting defects and complex shaped defects)
• Be able to differentiate between the most common pipeline inline inspection methods and recognize the impact of inspection uncertainties on assessment of corroded pipelines
• Be able to list the most common pipeline corrosion mechanisms and describe methods for predicting time development.

Target group

Engineers evaluating pipelines in operation and pipeline engineers working with pipeline condition/fitness for service assessments and inspection planning.
