About the course

This course is suitable for operator, contractor and supply chain personnel, and also those regulating the process. This course is designed to explore the considerations for the integrity management of ageing systems and detail the steps required to justify continued and safe operation beyond original design life. It also covers the assessment of various time-dependent degradation mechanisms, operability and obsolescence issues. Finally, our engineering experience in the field of pipeline lifetime extension will be highlighted throughout the course using a series of case studies.

Jee convened the working group responsible for the development of ISO TS 12747, defining a methodology for the lifetime extension (LTE) of rigid pipelines. We are currently in the process of extending the scope to include flexibles.

What past delegates have said about our courses

As expected Jee have provided us with a very good training course covering Subsea Systems from head to toe. It was a very good wrap-up of all what is related to Subsea Systems explaining a lot of what we do experience in our companies on daily basis

Mohamed Khater, Total

It was very helpful course for my current work. I learned more about subsea inspection, maintenance, integrity. All tutors are professionals. Providing material was very interesting and comprehensible
