COURSE OVERVIEW:

The meaning of pipeline repair encompasses the technical selection and physical application of restoration techniques used to return a degraded pipeline to its original design capacity and safety factor. This course provides a comprehensive evaluation of the various permanent and temporary repair methodologies available to the modern pipeline operator, ranging from traditional steel sleeves to advanced carbon fibre composites. By understanding the mechanical interaction between the repair and the host pipe, participants can ensure that the selected solution effectively mitigates the identified threat, whether it be metal loss, cracking, or mechanical damage.

The scope of this training is deeply rooted in the ASME PCC-2 standard (Repair of Pressure Equipment and Piping) and the relevant sections of API 1160 and ASME B31.4/B31.8. Participants will explore the engineering requirements for "Type A" (reinforcing) and "Type B" (pressure-containing) sleeves, as well as the unique application procedures for mechanical leak clamps. The course provides a rigorous comparison of steel-based repairs versus non-metallic composite wraps, focusing on the long-term durability, environmental limitations, and installation complexities of each system in both onshore and offshore environments.

The coverage of the program includes twelve modules that guide the participant through the repair lifecycle, from initial defect characterization to post-repair inspection and documentation. Key topics include the metallurgy of in-service welding, the chemistry of composite resins, and the engineering calculations required for "Cut-Out" and replacement operations. The course also addresses the practicalities of hot tapping and line stopping as enabling technologies for major repairs. The program concludes with a focus on quality control and the development of a repair selection matrix to facilitate rapid decision-making during integrity excavations.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Categorize pipeline defects to determine the most appropriate repair strategy.
• Apply the requirements of ASME PCC-2 for the design of pipeline repairs.
• Differentiate between Type A (Reinforcing) and Type B (Pressure-Containing) sleeves.
• Design a composite wrap repair based on defect size and operating pressure.
• Understand the risks and controls for in-service welding on pressurized lines.
• Evaluate the use of mechanical leak clamps for temporary and permanent fixes.
• Execute the technical requirements for a pipeline "Cut-Out" and replacement.
• Analyze the impact of thermal expansion and soil loading on repaired sections.
• Calculate the required thickness and length of steel repair sleeves.
• Specify the surface preparation and environmental conditions for composite applications.
• Perform quality control inspections on completed repairs using NDT methods.
• Document repair activities to maintain the integrity and traceability of the asset.

TARGET AUDIENCE:

This course is intended for Pipeline Integrity Engineers, Maintenance Supervisors, Field Technicians, Welding Engineers, and Quality Assurance Personnel responsible for pipeline remediation.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
