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

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).
