The Safety Performance of Natural Gas Transmission and Gathering Systems

  • A very small percentage of operators experience a reportable incident, range of 33 in 2000 to 56 in 98

  • Safety incidents seldom cause fatalities, reportable injuries fell from 12.1 per year in 85-94 to 6.7 for 95-01

  • Largest cause of onshore incidents is “third party damage” and second is “corrosion”

  • New technology, new management mechanisms and improved operations standards prevent safety incidents

  • Study was completed Q1-03

  • Incidents per unit of gas transported fell by 40% from the three years 85-87 to 99-01

Slide7 l.jpg

Fatigue in Energy Pipelines due to Internal Pressure

  • A new study was initiated at beginning of this year

  • Initial scope is to develop a “Primer” on fatigue then look at the effects of cyclic loading due to variations in operating pressure on pipelines

  • Kiefner and Associates was selected as contractor to develop technical information and incorporate liquid industry findings

  • Gap analysis will be conducted to identify future research, if needed

  • One expected output is the development of a process which identifies when and if fatigue is an issue for a given pipeline segment

  • Peer review is anticipated through a University


Slide8 l.jpg

Gas Pipeline Systems Performance Metrics

  • Draft of Interim report has been completed

  • Presently on hold due to uncertainty in direction by the Office of Pipeline Safety

  • Section 1 - Includes the four metrics from the B31.8S Standard, this is the present OPS solution

  • Section 2 - looks at customer interruptions, gas capacity reductions, and number of permits required to implement the IMP, this may be used on voluntary basis

  • Section 3 – very detailed for each of the nine threats and all the OPS required operation and maintenance requirements, this will not be used


Vintage pipe l.jpg

Vintage Pipe

  • This project is to provide additional information for the manufacturing and construction threats for the Integrity Management Program

  • Battelle is working on the report, to be published by the end of 2003

  • Report focuses on issues that are related to material and construction vintage issues, primarily pre-70

  • Includes information on certain materials and certain construction techniques that may require additional efforts in the Integrity Management process

  • Report will also give guidance on remediation do’s and don’ts


Slide10 l.jpg

New Industry Standards Status

  • External Corrosion Direct Assessment – NACE

    RP-0502 completed in October of 2002 and published. Presently being revised.

  • Internal Corrosion Direct Assessment – NACE RP-0104, dry gas, planned for completion in mid 2004. Wet gas systems to be completed in 2005.

  • Stress Corrosion Cracking Direct Assessment – NACE RP-0204, planned for completion in late 2004.

  • In-line Inspection Systems Qualification – API 1163, planned for completion in mid 2004, umbrella standard for in-line inspections

  • In-line Inspection Operations – NACE RP0102 to be revised in early 2004 to reflect changes in other standards.


Slide11 l.jpg

New Industry Standards Status

  • In-line Inspection Personnel Qualifications – ASNT ILI PQ - 2003, planned for completion in mid 2004.

  • Communications with Public – API 1162, final draft available for review on API web site. This was approved and is being published.

  • Internal Corrosion Control – expired standard that is being re-instituted, issues with lack of change in re-write

  • Qualification of Pipeline Personnel – ASME B31Q, this standard is being drafted with planned completion in late 2004.

  • ASME B31.8S – being revised for technical and editorial changes plus new appendix on Confirmatory Direct Assessment


Slide12 l.jpg

Reporting on Incidents by Threat

  • B31.8S used the 22 threats identified in previous incident studies by Kiefner

  • OPS’s new Incident Report has 25 threats. No one is sure how this discrepancy occurred. For the time being a interim solution has been identified

  • The desire to merge gas and liquid reporting format into a single fluid reporting format is being discussed

  • A desire to standardize internationally has been expressed by the industry and the US regulators, first step may be a North America Standard


Slide13 l.jpg

Trends in R&D and Standards Development

  • More coordination among standards developers and more guidance by pipeline industry in general

  • OTC preliminarily approved concept of increasing technology transfer through standards and other publications

  • OTC approved alignment of PRCI activities with standards development

  • B31.4 and B31.8 to work more closely beginning in 2004. Includes considerations for joint publications such as integrity management (B31S), damage prevention (B31P), dent and gouge assessment (B31D), and B31G re-write.

  • Re-affirmation of existing standards (API 1110) and elimination of duplicates (API 1160)


2004 research projects l.jpg

2004 Research Projects

  • Compendium of Best Practices With Current and Emerging Technologies to Prevent Mechanical Damage

  • Improvement of the Utility of the National Pipeline Mapping System

  • Locate Mechanical Damage on Pipelines

  • Continued Sage Use of Early Generation Pipelines

  • Reliability-Based Design Alternatives

  • Optimize Integrity Assessment Intervals

  • Improved Underground Storage Integrity Assessment

  • Managing of Stress Corrosion Cracking


2004 research projects15 l.jpg

2004 Research Projects

  • New Materials and Welding Process to Lower the Costs of New Pipeline Construction

  • Determination of Maximum Safe Surface Loads

  • Leak Detection and Notification

  • Prevention of Critical Pipeline Strains

  • Effective Flow Measurement

  • Solutions for Adverse Crossings

  • Product Quality

  • Improved Cavern Design and Operations

  • Improve Application and Inspection Techniques for Field Coatings


Research funding beyond 2004 l.jpg

Research Funding Beyond 2004

  • 2004 Research Budget for Transmission is approximately $12 million

  • 2004 Research Budget for Distribution is approximately $50 million

  • In 2004, FERC funding will expire leaving research to be funded on a voluntary basis

  • DOT funding has increased dramatically in recent years to where it now stands at over $10 million per year

  • How do companies justify collaborative research in the present environment ?????
