1 Root Cause Analysis Enhancement Jan 21, 2006 Presented by: Mohammed A. Al-Dossary Construction Engineering & Management Quality Management CEM 515 Term Paper 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 Forming Investigation Committee Management appointed a leader from Maintenance Leader selected members from operations (customer), maintenance and engineering Committee members = 5 Op Manager Maint. Manager DCS Engineer Process Engineer Electrical Engineer Mechanical Engineer Team Leader

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

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 External benchmarking Personnel interviews Current quality of Investigation Personnel satisfaction of current system Hidden back breaks Expectations

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

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

14 Quantitative Methodologies 50% 24% 13% 5% 3% Instrumentation Mechanical Electrical Human Error Process Unknown By Category
