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).
- Geotechnical instrumentation (inclinometers, piezometers, extensometers, topographical control).
- Remote sensing (satellite monitoring, multispectral imaging, LiDAR, radar).
- Unmanned Aerial Vehicles (UAVs), drones.
- Topography, fiber optics, among others.
- Proposals for the application of state-of-the-art monitoring methods such as virtual reality, predictive models, early warning systems, artificial intelligence (AI).
- Practical management cases of specific monitoring techniques including the integration and analysis of results, operational intervention, and correlations with expected time of interventions.
