This 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 is especially designed for

• Project managers,
• Engineers,
• Maintenance and technical personnel responsible for pipeline integrity assurance, flow assurance, corrosion control, and safety.

Pigging for Operation and Maintenance

• Pigging during construction
• Pigging during operation
• Utility Pigs
• Cleaning pigs
• Sealing pigs
• Gauging pigs
• Dual diameter pigs
• Magnetic cleaning pigs
• Designing a Pipeline for Pigging
• Pig traps and pigging stations
• Location and tracking devices

In-line Inspection (ILI) Tools - Theory, Performance, and Detection Limits

• Metal loss In-line Inspection
• Other In-Line Inspection Tools
• Crack detection pigs
• Mapping
• Geometry and bend-detection pigs
• Wax deposition measurement
• Spanning pigs
• Semi-intelligent pigs

Designing and Implementing an In-line Inspection (ILI) Program

• Selecting an ILI Tool
• Specific Design Considerations for Running ILI Tools
• Launch and Receive trap design
• Bends, tees, and valves
• Issuing an Inquiry
• Schedule requirements

Preparation for ILI

• Controlling Operational Parameters During the Inspection Run
• Strategy for Contract Development and Negotiations
• Developing a good specification
• Contingency Planning for a Stuck Pig
• Offshore risers
• Onshore flowlines, gathering system main sections or laterals

Post In-line Inspection Issues

• Quality Assurance Check of the Data
• Development of Protocols for Response
• Prioritization of the Dig Plan

• US regulatory requirements

• Criteria for dents

Validation of Results:

• Planning and preparation for field NDE
• Comparison between ILI, field NDE and actual:

• Corrosion
• Dents - effects of re-rounding

• Establish level of confidence

Fitness for Purpose: Assessment

• Assessment of defects
• Establish long-term integrity management program
• Incorporation of results in risk programs
• Potential Repair Consideration

CGFA attendance certificate will be issued to all attendees completing minimum of 80% of the total course duration.
