About the course

This course is suitable for learners involved in the integrity management of flexible pipelines and risers (both rigid and flexible). It builds a comprehensive understanding of the threats particular to these components and how they can be mitigated. From development of the integrity management system to assessment of the scheduled inspection, testing and monitoring results, the course provides learners with the skills needed to understand and manage the condition of their assets throughout life.

Learning outcomes

  • Explain the need for and components of an integrity management system
  • Recognise the riser configurations commonly utilised in the oil and gas industry, and describe their unique features
  • Identify the differences between rigid and flexible risers make up and their associated integrity threats
  • Recognise the inspection, monitoring and testing options available to mitigate these threats
  • Apply best practice to develop risk-based inspection approaches
  • Evaluate the impact of inspection findings on fitness-for-service of the flexibles and risers throughout life
