The 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.


Gary Smith is president of Inline Services, a Houston-based company specializing in pigging equipment and services. He has 27 years experience in the pipeline pigging industry, working in services such as commissioning and maintenance of pipelines as well as with designing and manufacturing pigging equipment.

Dr. Martin Phillips is a Senior Engineer with CC Technologies Services, Inc. He has more than 20 years experience with ILI and pipeline integrity services, including management of multi-pipeline inspection programs using different ILI tools and development of ILI tools for metal loss and cracking.

George Williamson, is currently Segment Engineering Technical Authority – Inspection, for the Upstream Global Projects group within BP. He has more than 25 years of Operations, Maintenance and Integrity Management experience. He is a registered professional engineer, NACE certified corrosion and a cathodic protection specialist. He has managed compliance and integrity programs for production facilities, gathering systems, liquid and gas transmission pipelines.

Course Notes

Included with the course fee is a detailed set of lecture notes and tthe reference handbook Pipeline Pigging & Integrity Technology, 3rd Edition, by J.N.H. Tiratsoo (600pp hardcover - a $125 value) providing invaluable reference documents after the course.

Continuing Education Units

Upon completion of the course, participants will be eligible to receive 1.2 Continuing Education Units (CEUs).
