Performing Pipeline Rehabilitation

Course objective

This course is centered on the practical aspects of pipeline rehabilitation and covers both internal and external rehabilitation. The course goes into depth on how to safely rehabilitate operating pipelines using manual and automated equipment.  Movement of in-service pipelines is analyzed in detail including the application and methodology of recommended practice API 1117. Other industry standards applicable to pipeline rehabilitation are discussed as well as how they should be incorporated into project specifications. 

Approximately half of the course is spent in analyzing case studies of field rehabilitation projects from around the world.  Over 400 photographs are used to illustrate how the work was performed and the results obtained.  The course presents techniques for performing the work with a combination of in-house personnel and outside contractors to minimize costs while maintaining clear lines of responsibility.

Who should attend

Engineers involved in:

• Determining the best way to rehabilitate a section of pipeline,
• Preparing the project specifications,
• Performing the necessary engineering calculations to insure the project is carried out safely,
• Health and safety issues specific to rehabilitation projects.

Field Operations Personnel and contractors who need to be aware of many alternatives techniques available for pipeline rehabilitation and their cost impact.

Inspection Personnel involved in evaluation of defects and selection of proper repair techniques.

Lecturer

Sidney A Taylor is president of Incal Pipeline Rehabilitation, Inc. He has over 30 years’ experience in the design and development of automated high-pressure water jet cleaning and coating systems. Prior to Incal, Sid worked with Schlumberger as a designer and manufacturer of well-logging tools and equipment, with MW Kellogg as a senior regulatory attorney, with Weatherford as general manager of water jetting systems, and with CRC-Evans as vice-president, engineering and marketing, where he was responsible for engineering design, manufacturing, and world-wide marketing of pipeline rehabilitation systems.
