 In-Line Inspection


IN-LINE INSPECTION COURSE

 

 

This course will discuss the general benefits of In-Line Inspections (ILI) The intent of the lectures is to provide the student with a comprehensive overview of the many and varied activities that are involved during the in-line inspection process. During the lectures, the technology principles and operation will be explained along with strengths and limitations of the techniques used. Some practical examples will be described.

 

 

 

INTRODUCTION

?     What is inline inspection (ILI)?

?     Why do we do ILI?

?     Pipeline failure modes

?     Overview of ILI tools

?     Gauge plates and profile tools
