Planning and executing subsea intervention

About the course

This two day course provides an awareness of the main aspects of subsea intervention and will help you address typical subsea issues such as choke failures, dropped objects, pod failure, valve failure, flying lead or jumper failures. 

Focusing on the different types of intervention and the typical methods for inspection, repair and maintenance, you will learn  how to assess unique subsea emergency problems and identify solutions. Moving on from identification through to logistics and testing, this course will teach you how to develop risk based remedial and contingency plans. The tutor will also share his experience of subsea component failures and interventions during the course.

This course is ideal for engineers, technical team leaders and managers looking for a grounding in the tools and methods available for subsea intervention.


Learning outcomes

  • Recommend preferred type of intervention(s) and tools given a specific mission role or scenario
  • Investigate and analyse data from a non-routine work and from a routine inspection report and develop a remedial plan
  • Develop a logistical plan for implementing an intervention
  • Develop a contingency plan and recommend a procedure based on results of the risk assessment
  • Describe lessons learned that should be considered in subsea systems design
