Training on Oil and Gas Pipeline Operations and Integrity Management

Module 1: Pipeline System Overview and Components

• Types of pipelines: crude, natural gas, NGL, and products.

• Key components: pipes, valves, pumps, compressors, pig traps, and SCADA.

• Pipeline categories: gathering, transmission, and distribution.

• Case Study/Hands-on Exercise: Map a pipeline system from wellhead to refinery or market, identifying key components and control points.

Module 2: Pipeline Hydraulics and Flow Assurance

• Fundamental hydraulics: pressure drop, flow rate, and friction losses.

• Pump and compressor station operations.

• Flow assurance: hydrate prevention, wax deposition, and slugging.

• Case Study/Hands-on Exercise: Calculate pressure drop across a pipeline segment given flow rate, diameter, and fluid properties.

Module 3: SCADA and Pipeline Control Systems

• SCADA architecture: remote terminal units (RTUs), programmable logic controllers (PLCs), and master stations.

• Real-time monitoring: pressure, flow, temperature, and density.

• Alarm management and emergency shutdown (ESD) systems.

• Case Study/Hands-on Exercise: Simulate a SCADA console response to a pressure drop alarm, triaging possible causes and initiating appropriate actions.

Module 4: Pipeline Integrity Management Systems (PIMS)

• API 1160 and ASME B31.8S integrity management frameworks.

• Integrity management plan: threat identification, risk assessment, and mitigation.

• Key threats: corrosion, cracking, third-party damage, and geohazards.

• Case Study/Hands-on Exercise: Develop a pipeline integrity management plan for a 100km crude oil pipeline, identifying threats and prioritizing mitigation actions.

Module 5: Inline Inspection (ILI) and Pigging Operations

• Types of ILI tools: magnetic flux leakage (MFL), ultrasonic (UT), and caliper.

• Pigging programs: cleaning pigs, gauging pigs, and intelligent pigs.

• Launching, receiving, and tracking pigs.

• Case Study/Hands-on Exercise: Plan an ILI run for a natural gas pipeline, including pig selection, launch/receiver site preparation, and data interpretation.

Module 6: Corrosion Control and Cathodic Protection

• Types of pipeline corrosion: internal and external.

• Cathodic protection (CP): sacrificial anodes and impressed current systems.

• Coating systems and corrosion inhibitors.

• Case Study/Hands-on Exercise: Conduct a cathodic protection survey on a pipeline segment, interpret potential readings, and identify under-protected areas.

Module 7: Hydrostatic Testing and Direct Assessment

• Hydrostatic testing: pressure test procedures, safety, and acceptance criteria.

• External corrosion direct assessment (ECDA), internal corrosion direct assessment (ICDA), and stress corrosion cracking direct assessment (SCCDA).

• Integrating direct assessment with ILI and hydrotest.

• Case Study/Hands-on Exercise: Develop a hydrostatic test plan for a pipeline segment, including test pressure, hold time, safety zones, and acceptance criteria.

Module 8: Leak Detection Systems

• Leak detection methods: computational pipeline monitoring (CPM), real-time transient modeling (RTTM), and fiber optics.

• Acoustic and vapor sensing for leak detection.

• Alarm management, leak location, and confirmation.

• Case Study/Hands-on Exercise: Analyze a simulated leak detection alarm from a CPM system, calculate estimated leak location, and initiate emergency response.

Module 9: Pipeline Repair and Emergency Response

• Repair methods: sleeves, clamps, pipe replacement, and composite wraps.

• Emergency response plans: isolation, depressurization, and environmental containment.

• Coordinating with local authorities and emergency services.

• Case Study/Hands-on Exercise: Simulate an emergency response to a pipeline rupture, including isolation, depressurization, notification, and spill containment.

Module 10: Regulatory Compliance and Pipeline Safety

• Key regulations: US DOT PHMSA (49 CFR 192, 195), API standards, and local equivalents.

• Operator Qualification (OQ) and public awareness programs.

• Integrity reporting, inspections, and enforcement actions.

• Case Study/Hands-on Exercise: Conduct a regulatory compliance audit for a pipeline segment, identifying gaps against applicable regulations and developing corrective actions.
