  1. Construction Engineering & Management Quality Management CEM 515 Root Cause Analysis Enhancement Term Paper Jan 21, 2006 Presented by: Mohammed A. Al-Dossary Abqaiq Plants Today film

  2. Outline • Part I: Abqaiq Plants Overview • Plants Background • Plants Processes • Plants in Saudi Aramco Organizational Chart • Part II: Root Cause Analysis Program • Initial investigation • Review Methodologies • Summary • Lessons Learned

  3. Upset Definition An unplanned shutdown of critical equipment during normal operation which may lead to production losses.

  4. Problem Statement Top Management Statement: We would like a team to work on identifying the root causes of the nuisance and repetitive upsets! We don’t want more upsets please!

  5. Team Leader DCS Engineer Process Engineer Electrical Engineer Mechanical Engineer Forming Investigation Committee • Management appointed a leader from Maintenance • Leader selected members from operations (customer), maintenance and engineering • Committee members = 5 Maint. Manager Op Manager

  6. Investigation Methodology Kickoff meeting was started by the team leader and a Weekly meeting was scheduled which lasted for 4 hours

  7. Investigation Methodology Initial Review of archived reports Review of Current Investigation system External Benchmarking Personnel Interviews

  8. Investigation Methodology Initial Review of archived reports Review of Current Investigation system External Benchmarking Personnel Interviews

  9. Collect Data (Supv Opr) Ops. Foreman Calls for meeting Equipment Trip Trip Meeting (All) Recommendation & Action plan Enter Data (Supv Opr) Verify Data Ops Foreman Area Engineer Review Engineering Review Division Heads Review & Remarks Reliability Unit Review Investigation Methodology Investigation Workflow Initial Review of archived reports End Review of Current Investigation system Report Workflow (Manual) External Benchmarking Personnel Interviews End

  10. Investigation Methodology Initial Review of archived reports Review of Current Investigation system External Benchmarking Personnel Interviews

  11. Investigation Methodology Initial Review of archived reports Review of Current Investigation system Current quality of Investigation Personnel satisfaction of current system Hidden back breaks Expectations External benchmarking Personnel interviews

  12. Start Develop Team Mission Develop Team Name Study Methodologies Qualitative Quantitative Implementation Roadmap

  13. Quantitative Methodologies • Identified the data boundaries • Identified data population = 400 • Gathered all data for 4 years • Designed Q&D Access Database • Used Minitab to generate statistical analysis
