  • Design and construction of slope stabilization and erosion control works: new technologies and alternative solutions.
  • Definition during the design stage of geohazard monitoring systems and their installation during construction.
  • Examples of solutions to challenges due to environmental and social conditions.
  • Risk assessment and contingency management in the design and construction of pipelines.
  • Management of geohazards in transmission systems other than hydrocarbons.
  • Considerations for pipeline threats of anthropic origin.
  • Special cases of pipeline geohazard management in design and construction.
  • Cases of parallelism with coexistence and interference with other linear or specific infrastructures.
  • Analysis of design and construction cases.

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.
  • Third-party damage cases that have activated geohazards affecting the integrity of pipelines.
  • Practical cases of occurrence of unforced errors in the development of monitoring due to inadequate systems, invalid readings, among others.
  • Conventional or innovative geotechnical and hydrotechnical repair or mitigation solutions to maintain pipeline integrity.
  • Lessons learned on the processes of mitigation, monitoring, and management of pipeline geohazards.
