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.

**Please note that the Virtual Classroom is split over 4 days: 7th, 8th, 9th & 10th December 2021 from 0900 - 1300 GMT**

*Last date to benefit from the Early Bird rate is 26th October 2021

*Full prices £1,150/$1,600 (VAT added where applicable)



Learning outcomes

  • Explain the principles of operating pipeline pigs and isolation plugs
  • Compare different types of pigs and plugs and explain when and how they are used
  • Investigate problems that can occur when pigging and suggest resolutions
  • Apply industry lessons learned and best practice to your projects
