  1. Equilon Pipeline Company, LLC. OPS Workshop August 8, 2001 Equilon Pipeline’s Risk Management Program

  2. Equilon Pipeline Company, LLC. OPS Workshop August 8, 2001 • Background • Risk Screening Scorecard • Data Gathering • Risk Assessment Data Sheets • Risk Assessment Meeting • Documentation Software

  3. Equilon Pipeline Company, LLC. OPS Workshop August 8, 2001 Background • Risk Management Demonstration Project • Conducted Risk Assessments on two major systems • Recognized the importance of aligning/integrating data • Viewing & digesting data was very onerous • There has to be a better way

  4. PIPELINE RISK SCREENING - SCORECARD SCORING PROCESS Abbreviations: CAUSE INDEXESIMPACT INDEXES Outside Force Damage (OF) Population Density (POP) Corrosion (CR) Environment Sensitivity (ENV) Failed Linepipe/Weld (FP) Commodity Hazard (COM1/2) Operations (OP) Release Potential (DIA) Other (OT) Equation: Details: {OF%+CR%+FP%+OP%+OT%} X {[(POP)(COM1)+(ENV)(COM2)][DIA]} = SCORE The statements within each Cause Index are weighted relative to each other by “units” in parenthesis. Cause Indexes are weighted relative to each other by “%” in the upper right-hand corner. A pipeline system’s score for each statement is the product of the entry made (see STEPS) and the “units” shown. Statement scores within a Cause Index are added together, then multiplied by the Index’s weighting to get the Cause Index score. The System Probability score (%) is the sum of the five indexes. The statements within the Population Density and Environment Sensitivity Impact Indexes are weighted by “points” in parenthesis (POP-1 & ENV-1 - points/mile; ENV-2 - points/crossing). A pipeline system’s score for each statement is the product of the entry made (see STEPS) and the “points” shown. These statement scores are added together, then multiplied by factors relating to the Commodity Hazard and the Release Potential (diameter) of the pipeline, to obtain the System Consequence score (points). The System Relative Risk score (points) is the product of the System Probability score (%) and the System Consequence score (points). Probability Consequence Relative Risk 3 of 10
