Resources for Integrity Management

Resources for Integrity Management

• Marty Matheson, American Petroleum Institute
• OPS Public Meeting
• August 8, 2001
• Houston, TX

2
OPS Integrity Management Goals

• Accelerate integrity assessment of pipelines in
  high consequence areas
• Improve integrity management systems within
  companies
• Improve the governments role in reviewing
  adequacy of integrity plans
• Provide increased public assurance

3
Our vision is an oil pipeline industry that --

• conducts operations safely and with respect for
  the environment
• respects the privilege to operate granted to it
  by the public and
• provides reliable transportation of the crude oil
  and refined products upon which America and all
  Americans rely.

Resources on the Industry Safety Record

• The U.S. Oil Pipeline Industrys Safety
  Performance (Trench report), 1999 (with update
  to be issued in the near future)
• API Publication 1158, Analysis of DOT Reportable
  Incidents for Hazardous Liquids Pipelines
  (1986-1996)
• Annual review of pipeline accidents by ASME B31.4
  Committee

An Upcoming Report --

• Oil Pipeline Characteristics and Risk Factors
  Illustrations from the Decade of Construction
• Authors
• Cheryl Trench, Allegro Energy Group
• John Kiefner, Kiefner Associates
• Analyses of data from the Pipeline Performance
  Tracking Initiative

8
Pipeline Performance Tracking

• Incidents down to 5 gallons
• 20 cause categories based on ASME
• Detail, detail, detail
• Over 140,000 miles of pipe or more than 90 of
  OPS mileage
• Infrastructure information
• Miles by diameter
• Miles by decade of construction, etc.

9
Oil Pipeline Characteristics and Risk Factors

• History of pipe and pipeline technology
• Data on pipeline mileage by decade of
  construction
• Analyses of OPS incident data (1986-1999) based
  on the historical perspective of technology and
  practices and the decade of construction
• Findings and recommendations for use in risk
  analysis

All Incidents and Pipeline Miles by Decade of
Construction
If share of incidents (?) is higher than share of
miles (?), decade has a high rate of incidents
per mile. If lower, decade has a low rate.
Causes based on Kiefner Assoc. classification
for ASME B31.4 Committee, 1986-99 line
pipe only excludes incidents where year of
installation was unspecified.

Findings and Recommendations

• General findings
• Specific recommendations for pipe
• Pre-1930s
• 30s and 40s
• 50s and 60s
• 1970 and later
