September  2011: Data Request for PHMSA ERW Research Project

Request for Data pertaining to ERW Seam Integrity Assessments and for ERW Seam Failure Investigations. Kiefner & Associates is seeking data for the PHMSA research project entitled “Understanding Low-Frequency ERW Pipeline Failures” (U.S. DOT Other Transaction Agreement No. DTPH56-11-T-000003). In pursuit of this research on the behavior of flaws in ERW pipe, we are requesting data that can be used to evaluate the effectiveness of in-line inspection (ILI) and hydrostatic testing as means of assessing ERW seam integrity and to assess the causes of ERW seam failures. Your company may already have received specific requests from one or more of the team members companies (Battelle, DNV, or Kiefner). If so, we appreciate your consideration of those requests. If your company has not received specific requests for data and you have data that would benefit this effort, we are interested in learning about your experiences. Any data that are contributed to the project will not be associated with the names of operators or pipelines. Specific dates of failures or assessments will not be mentioned either. The types of data that will be presented are pipe attributes and the nature of failures and assessments, so the identity of operators who contribute data will not be made apparent.

If you would like to contribute to this important research initiative, please contact Kolin Kolovich at kkolovich@kiefner.com or (614) 410-1611 for more information.

September  2008: KAI hires Dr. Martin Phillips as a Senior Pipeline Specialist (ILI)

Kiefner & Associates, Inc. is pleased to announce that Dr. Martin Phillips has joined our staff as Senior Pipeline Specialist (ILI). Martin, formerly with CC Technologies (a DNV Company) and PII (now GE Pipeline Solutions) has 27 years of experience in the application of in-line inspection technologies (ILI) to pipeline integrity assessment and management as well as developing integrity management plans involving risk assessment and management. His strengths lie in understanding the ILI technologies from conception, design, testing, and qualification through service implementation in oil and gas pipelines. This expertise covers data analysis and a thorough understanding of ILI specifications as they apply to pipeline defects from corrosion, deformation, and cracking. Martin has significant expertise and understanding in the area of ILI for cracking such as stress corrosion cracking (SCC) and fatigue cracking, which is a relatively new ILI technology. His experience goes beyond the initial response to ILI reports to the use of the ILI data (metal loss and cracking) for remaining life calculations and re-assessment intervals. Martin was involved in the development of API 1163 and ASNT ILI PQ. This ILI expertise is now available through training courses offered by KAI. Martin is a member of PIPE, PPSA, NACE and the IOP (UK).


April  2007: SCC and Corrosion Soils-map Based Risk Model

Kiefner & Associates Inc. (“KAI”) and Coast to Coast NDE (“Coast”) have jointly developed a Soils-map Based Risk Model. The model utilizes government soils mapping available as GIS shape files to calculate relative values of 10 variables relevant to SCC and corrosion. It then dynamically segments the client’s pipeline based on those 10 variables and assigns relative risk values for both types of SCC, external corrosion and MIC to each dynamic segment. The model is mechanistic and, as such, does not rely upon identifying “good” or “bad” soil types or upon the Client requiring any statistical data of discovered SCC. The model is based upon industry understanding of the most likely locations for SCC as a function of coating type, coating condition and CP effectiveness. If the SCC is occurring elsewhere than industry knowledge would indicate, the risk algorithms can be readily modified to reflect the Client’s unusual situation. If field investigation indicates that the coating condition or cathodic protection in a particular segment is better than indicated by the model based upon the soils and drainage conditions in that segment, the tabular values for those variables can be readily over-written in the Client’s GIS, which will immediately reduce the calculated risk value for that segment. Similarly, if the government maps indicated different drainage conditions than are found, any of the variables driving the risk algorithms can be adjusted accordingly. Having the pipeline segmented in terms of soils and drainage characteristics has the added advantage of providing an additional reference frame with which to describe the pipeline. This can be valuable, for example, to identify similar sites if, as required by the GAS IMP Rule §192.917(e)(5), extensive corrosion were to be found.

KAI and Coast jointly own and market the Soils-map Based Risk Model. All sales of the customized Soils-map Based Risk Model are based upon a Purchase Order for which Coast, KAI and the Client will all be signatories. The Purchase Order will include a Technical Description on which Coast, KAI and the Client agree that has been developed as a result of at least one meeting at which Coast, KAI and the Client are all present.

Customized Soils-map Based Risk Models that calculate relative risk of both types of SCC, external corrosion and MIC are offered for sale at a lump sum price per county based upon a minimum of 15 counties. Additional or unusual requirements by the Client may require a slight increase in the per county rate as agreed by all three parties and included in the Purchase Order. The current base price is included in the confidential Joint KAI-Coast Technical Description and Pricing Brochure that is available upon request to interested pipeline operators.


February  2007: Dr. John Kiefner retires

KAI announces the retirement of Dr. John F. Kiefner, after a 40-year career in the pipeline industry.  Dr. Kiefner practiced and espoused pipeline integrity management planning, and developed many of the tools and concepts to make pipeline integrity management possible, long before it became a standard practice.  He began his involvement with the pipeline industry at Battelle Memorial Institute – Battelle Columbus Labs (with a stint in the Houston office).  While there, he worked in close partnership with Bill Maxey and others to develop, test, and demonstrate numerous important concepts that led to practices widely used in the industry today.  These included:

  • Developing the NG-18 log-secant equation describing the failure stress of pressurized pipe affected by an axial defect
  • Developing analysis tools for evaluating corrosion defects in pipe such as the Modified B31G and RSTRENG
  • Testing the effectiveness of reinforcement sleeves for the repair of pipe and in-service maintenance welding
  • Demonstrating the effectiveness of hydrostatic testing and in-line inspection as techniques for revalidating the integrity of a pipeline
  • Developing an understanding of the behavior of low-toughness ERW seams.

After 23 years at Battelle, he founded Kiefner & Associates, Inc. (KAI) in January 1990, a firm dedicated to serving the oil and gas pipeline industry. While he was with KAI, his further achievements on behalf of the pipeline industry include:

  • Raising pipeline failure investigation to new levels of quality in the industry
  • Contributing to the continued improvement of ASME codes and standards
  • Developing one of the first comprehensive algorithmic approaches to relative risk assessment of pipelines
  • Writing the first comprehensive pipeline repair manual
  • Testing the effects of mechanical damage on oil and gas pipelines and the effectiveness of damage repair techniques
  • Developing a process for evaluating the susceptibility of pipe seams to fatigue due to pressure cycles.

The company Dr. Kiefner created, KAI, has since grown to 18 employees and looks forward to providing specialized, personal technical service to the pipeline industry.  Dr. Kiefner will continue to participate in company activities and assist clients on a greatly reduced schedule while he pursues other personal interests.
