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 • Magnetic flux leakageCrack
detection tools (CD) – including Elastic Wave tool • Caliper tools • IMU tools • What is integrity management of
pipelines? • Integrity assessment of
pipelines - applicability • Pressure testing (gas and hydro)
• ILI • Direct Assessment (DA) • How does ILI fit with integrity
management?

DETAILS OF TOOLS
METHODOLOGY • Calliper • MFL • CD • EXECUTION OF ILI • Logistics • Project management issues • Feasibility to inspect lines • Service interruption issues • Mob, de-mob • Launching, tracking, and
receiving of tools • Launchers and receivers • Launching and receiving
facilities • Temporary and permanent
facilities • Pig tracking devices • Storage and retrieval of data

|
USE OF ILI RESULTS • Examples of ILI reports • Calliper tools (assessment of
dents and other deformation) • MFL (B31G, RSTRENG, DNV F101
etc.) • CD (Fracture mechanics
considerations – brittle versus ductile behaviour – toughness) • SUMMARY o
