In-line inspection (ILI) technology has been in widespread use approximately 30 years and has become the preferred method used by pipeline operators to ensure the integrity of their pipeline assets.
This pioneer training course is aimed at improving accuracy and reliability in the application, interpretation, and evaluation of data acquired from in-line inspection devices. The course presents practical methods of risk-based ILI technology as applied to pipeline integrity problems. The course is highly interactive, and takes the forms of lectures, workshops, case studies, and discussions.
Objectives
The course is designed for professionals who need to know the basics of acquiring and interpreting ILI data when assessing pipeline integrity and safety. The participants will get a working knowledge of the basics of the engineering approach to ILI data extraction, mining, fusion, and analysis. They will also get essentials of the current international codes that regulate ILI systems quality (API 1163, NACE Standard RP 0102-2002, NACE 35100, ASNT ILI-PQ 2005), and how to use them on a daily basis.
Who Should Attend
Gas and liquid pipeline professionals involved with ILI data analysis, direct assessment, maintenance and repair, regulators, IMP managers, risk managers, specialists in new technologies for pipeline integrity and safety, among others.
Continuing Education Units (CEUs)
On satisfactorily completing the course, participants will be eligible to receive 2.6 CEUs.
Course Documentation
Participants receive a sturdy ring binder containing all the lecture slides with notes and illustrations supporting the lectures.
