Pigging Operations and Techniques

OVERVIEW

Why Choose Pipeline Pigging Operations Training Course?

The purpose of this training course is to present the requirements for the relevant industry practices regarding inspection and condition monitoring of pipeline systems using pigging devices, with the final goal of optimisation of maintenance and efficiency of pipeline operation. The course will provide guidelines for carrying out inspection and pipeline defects and detection of potential failures due to material degradation and other operational causes. The delegates will be introduced to a risk analysis of equipment failures and available prevention and remedial technologies. Fitness for service (FFS) methodology will be introduced and explained.

This training course includes several workshops with real problems from industrial practice which will enable discussions and exchange of experiences.

The training course will feature:

• Methods for inspection and effective maintenance of pipeline systems.
• Planning and practical issues regarding pigging devices
• Data collection and analysis of smart pig NDT tests
• Development of maintenance and repair program based on inspection
• Analysis of cases studies during several workshops

OBJECTIVES

By the end of this course, participants will be able to:

• Understand the requirements of industry standards for pipeline inspection:
• Carry out inspection of pipeline systems with NDT testing instrumentation
• Develop efficient maintenance programmes
• Implement technologies recommended for repairs and alterations
