Topic 2: Analysis and evaluation of risks due to geohazards and their planning in pipeline integrity management
Considerations on pipeline geohazard risks:
- Characterization of pipeline geohazards using background information from design, construction, operation, maintenance, and integrity, and their impact on risk management.
- Triggering agents (e.g., rainfall, earthquakes) in geotechnical and hydrotechnical processes.
- Geomorphological environment processes such as inventory, susceptibility zoning, and geohazard identification.
- Admissible thresholds for critical variables (e.g., rainfall thresholds, pipe deformations, relative displacements, seismic and volcanic activity, third-party damage).
- Risk management due to technological accidents (NATECH).
- The interaction with third parties and its combined effects with Geohazards.
Implementation of decision-making processes in pipeline integrity management planning:
- Strategies for data collection, capture, preparation, and management.
- Multidisciplinary analysis of integrity threat interaction and their consequences compared with broadly acceptable, ALARP, and non-tolerable risks.
- Risk analysis, criteria, and evaluation methodologies and lessons learned (i.e., probability of occurrence of Geohazards, vulnerability of the pipeline, effectiveness of mitigation and resistance, analysis of consequences including spill simulation).
- Development of integrity plans and prioritization based on multidisciplinary analysis.
- Roadmap planning and implementation of digital transformation technologies.
Topic 3: Implementation of geohazard monitoring and mitigation, and integrity performance management
Covers the application of monitoring, mitigation actions and lessons learned in the management of geohazards.
Application of technologies for monitoring geohazards in pipelines related to automated or manual techniques, such as:
- In-Line Inspection (e.g., inertial, geometric, corrosion).
