Upon completion of this course, participants will be able to:

• Explain the principles, benefits, and limitations of various In-Line Inspection (ILI) technologies (MFL, UT, Caliper).
• Plan, prepare, and execute a comprehensive pipeline hydrostatic strength and leak test.
• Interpret ILI data reports to accurately identify, size, and prioritize pipeline anomalies (corrosion, dents).
• Develop robust documentation and reporting required for regulatory compliance of hydrostatic tests.
• Detail the procedures for pre-test cleaning, water quality management, and dewatering/drying.
• Understand the safety protocols and risk management procedures for high-pressure testing.
• Manage the logistics and operational interface of ILI runs (pig tracking, launcher/receiver setup).

• Pipeline Integrity and Inspection Engineers.
• Project Managers and Construction Supervisors for new pipeline builds.
• Pipeline Operations and Maintenance Staff.
• Quality Assurance/Quality Control (QA/QC) Inspectors.
• Technical Personnel responsible for fitness-for-service assessments.
• Hydrostatic Test and NDE Contractors.

• Scenarios: Managing a pressure drop during the hydrostatic test hold period and initiating troubleshooting.
• Case Studies: Analyzing ILI reports to prioritize a dig list for remediation.
• Group Activities: Developing a detailed hydrostatic test procedure for a new pipeline segment.
• Individual Exercises: Calculating the minimum required test pressure based on MOP.
• Discussions on the safety risks associated with water disposal and high-pressure media.

Unit 1: Introduction to Pipeline Integrity and Inspection Tools

• Overview of the Pipeline Integrity Management System (IMS) and the role of inspection.
• Principles and applications of In-Line Inspection (ILI) technologies: MFL, UT, and Caliper.
• Selection of the appropriate ILI tool based on pipeline characteristics and threat type.
• Logistics and operational planning for pig tracking and ILI tool mobilization.

Unit 2: Hydrostatic Test Planning and Preparation

• Review of industry codes (e.g., API, ASME, PHMSA) governing hydrostatic testing.
• Defining the test section, test pressure, and establishing acceptance criteria.
• Procedures for cleaning, gauging, and filling the pipeline segment (water quality control).
• Safety risk assessment and emergency planning for high-pressure testing.

Unit 3: Execution and Analysis of Hydrostatic Tests

• Detailed procedure for pressurization, stabilization, and monitoring of the test section.
• Interpreting pressure-temperature charts and identifying a pressure loss due to leaks or temperature change.
• Procedures for controlled depressurization and line segment draining.
• Documentation, reporting, and sign-off requirements for final test certification.

Unit 4: Interpretation of ILI Data and Anomaly Assessment

• Reviewing ILI data reports: Identifying corrosion, metal loss, and mechanical damage (dents).
• Sizing and characterizing anomalies (e.g., corrosion depth, length, width).
• Prioritizing anomalies for immediate repair versus scheduled mitigation based on severity.
• The process of correlation: Dig-up, verification, and NDE techniques.

Unit 5: Post-Inspection and Test Activities

• Dewatering, drying, and inert gas purging procedures for new pipelines.
• Procedures for tie-in welding, NDE, and final commissioning.
• Integration of ILI and hydrotest data into the long-term Integrity Management System.
• Best practices for maintaining test equipment and calibration records.
