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

Probability
Consequence
Relative Risk
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).
