About the course

This course will help subsea pipeline and integrity engineers to understand how to use pipeline pigs and plugs to perform a variety of operations.

Providing an overview of pigs and plugs available and their functionality, the tutor will explain the latest theories on improving the reliability and accuracy of pigging, for both cleaning and inspection purposes. Analysing case studies and discussing how to avoid stuck pigs and plugs, learners will deepen their knowledge of how to run successful and safe pigging and plugging campaigns.
