Challenge

  • An urgent response and pipeline integrity assessment are important in emergencies. Emergency situations may arise when the pipeline is subjected to accidental loads or experiences abnormal configurations, such as displacement, subsidence, anchor drag or buckling, or is degraded due to severe corrosion or even leaks, etc.
  • An integrated pipeline integrity assessment in an emergency situation requires the right type and format of data to be readily accessible. The required data are often scattered, of inconsistent format or uncertain providence, or simply missing.
  • The lack of a common understanding and methodology for smart data storage and utilization impedes data’s usefulness in such circumstances.

Solution

  • Formulate guidance on the data required for an integrated assessment.
  • Develop a sample data format for design and construction data, operation data and historical inspection data. Develop a data storage system suitable for a pipeline’s whole service life.
  • Develop a data processing tool/system that immediately extracts and prepares data for assessment input, turning data into information and knowledge.

Benefits

  • Greatly improves a pipeline’s emergency-response readiness.
  • Greatly reduces the response time and time taken to reach critical decisions based on the results of damage criticality analyses, selection of temporary repair methods, etc.
  • Shortens or avoids unnecessary shutdowns or derating and reduces consequential loss.
  • Anonymously combines individual data to create shared industry knowledge.

Value

  • Shortens the time needed to make informed decisions.
  • Provides a timeline for the implementation of temporary or permanent repair solutions.
  • Improved preparedness.
  • Unified assessment for similar pipelines.
  • Reduced consequential losses and liabilities.
  • Potential cost reduction of from USD 200k to USD 2m.
