Strategic Pipeline Integrity: In-Line Inspection Tools and Maintenance Protocols
Start Date : 7 Dec,2025
End Date : 11 Dec,2025
Duration : 5 Days
Overview:
This is an in-depth course on the practical aspects of piping and pipeline integrity, maintenance and repair. Participants will be introduced to the technical basis of the ASME and API integrity rules, and their application to case studies and exercises. The participants will be able to recognize causes of degradation in-service, whether mechanically induced (pressure, vibration, fatigue, pressure transients, external damage) or due to corrosion (wall thinning, pitting, cracking), and apply integrity analysis techniques to make run-or-repair decisions. The participants will become knowledgeable in the technical basis and application of ASME B31.3, B31.4 and B31.8 piping codes, ASME B31G and API 579 Fitness-for-Service and Flaw Evaluation. The participants will review inspection techniques, from the most common (PT, MT, UT, RT, MFL pigs) to most recent (AE, PED, UT pigs and multi pigs), and the use of hydrotesting for integrity assessment and the implementation of integrity management programs, periodic inspections and evaluation of results. The course will review the various repair techniques, their advantages and shortcomings, and the logic to be followed in making repair decisions and selecting the applicable repair.
Course Objectives:
