Programme overview
Introduction:
Pipeline integrity management fails when hydraulics, station control, leak detection, pigging and inspection data are handled by separate teams that never build one picture of the line. Ruptures, product losses and forced derating often follow. This Core Concept course covers oil and gas pipeline engineering, operations and integrity management for transmission lines: codes and design basis, liquid and gas hydraulics, pump and compressor stations, SCADA and leak detection, pigging and in-line inspection, threat and risk assessment, defect assessment, repair and emergency response. Participants produce a Pipeline Integrity Management Plan for a segment of their own network.
Course Objectives:
- Verify the design basis, maximum allowable operating pressure and station setpoints of a liquid or gas transmission pipeline against its code and operating envelope
- Calculate pressure profiles, line pack and surge conditions and use them to set pump and compressor station operation
- Configure SCADA alarms, computational leak detection and pigging programmes that keep a pipeline within its operating limits
- Interpret in-line inspection and direct assessment results to classify anomalies and decide response and reassessment intervals
- Assess metal loss, dent and crack-like defects and select a repair method or pressure reduction with a documented change record
- Build a Pipeline Integrity Management Plan that links threats, risk ranking, inspection, maintenance, emergency response and performance indicators
Target Audience:
- Pipeline engineers responsible for design basis, pressure limits and hydraulic performance of transmission lines
- Integrity engineers responsible for threat assessment, in-line inspection programmes and defect disposition
- Operations supervisors responsible for pump and compressor station running and pipeline control
- Control room and SCADA specialists responsible for alarm handling and leak detection performance
- Maintenance supervisors responsible for pigging, valve maintenance, right-of-way patrol and repair execution
- Emergency response coordinators responsible for pipeline incident plans and drills
