T he use of in-line tools for inspection and cleaning is accepted as essential for the safe and profitable operation of all pipelines. Now, Regulations require internal inspections using geometry pigs for detecting changes in circumference and MFL or ultrasonic pigs for determining wall anomalies, or wall loss due to corrosion in onshore pipelines in the US. Offshore, pipeline operators wage a constant battle for flow assurance against paraffin, hydrate, and asphaltene formation in deepwater lines, and pigging technology combined with chemical treatment is their primary weapon.

The Pigging and In-line Inspection Course is designed to provide a comprehensive introduction to all aspects of utility and in-line inspection pigging. Led by four of the most experienced, independent experts in this field today, the course will be conducted as a workshop, and attendees will be actively encouraged to participate. The course content will be fully illustrated, with actual pigs and models being used to aid understanding and help overcome any language difficulties. Comprehensive course notes will be provided, which will form a valuable source of reference afterwards.

Who should attend

The course is especially designed for project managers, engineers, maintenance and technical personnel responsible for pipeline integrity assurance, flow assurance, corrosion control, and safety.

Course Notes

Included with the course fee is a detailed set of lecture notes and the reference handbook Pipeline Pigging Handbook, 3rd Edition, by J. Cordell and H. Vanzant (272pp - a $125 value) providing invaluable reference documents after the course.

Continuing Education Units

Upon completion of the course, participants will be eligible to receive1.4 CEUs.
