Carolyn Kolovich has over 16 years of pipeline industry experience. She began her career at Kiefner and Associates, Inc. upon graduation from The Ohio State University with a degree in Mechanical Engineering. During her career, she has participated in a variety of pipeline related projects with a focus on pipeline integrity and reliability. Ms. Kolovich has experience in fitness-for-service assessments, remediation plans, reassessment interval determination, defect assessment and codes and standards development. She is an ongoing member of the ASME B31.4 code committee. Michael J. Rosenfeld, P.E., is Chief Engineer with Kiefner/Applus-RTD in Columbus, Ohio. He holds a BS in mechanical engineering from the University of Michigan (1979) and a MS in mechanical engineering from Carnegie-Mellon University (1981). The focus of Mr. Rosenfeld’s career has been on oil and gas pipeline integrity since joining Kiefner & Associates, Inc. (KAI) as Senior Structural Engineer in 1991. He then served as President from 2001 to 2011. While at KAI, he performed numerous pipeline failure investigations, stress analyses of buried pipelines subjected to geotechnical and live loadings, fitness for service evaluations for pipelines affected by various degraded conditions, developed technical procedures for integrity management planning, and carried out industry-funded research on pipeline damage mechanisms. Mr. Rosenfeld is a current member of the ASME B31.8 Gas Transmission & Distribution Piping Section Committee, the ASME B31 Mechanical Design Technical Committee, the ASME B31 Standards Committee, and the ASME Board of Pressure Technology Codes & Standards. He was the primary author of the 2009 major revision to ASME B31G, is an ASME Fellow, and has authored a number of papers and articles on pipeline-related subjects. W. Greg Morris, P.E., is a Senior Principal Engineer at Kiefner/Applus-RTD. He has more than 20 years of experience throughout the pipeline industry, with a focus on pipeline materials, defect assessment, and integrity management. He has performed failure investigations of pipe and components from both natural gas and hazardous liquids pipelines and, when requested, in conjunction with third- party stakeholders and regulators. Mr. Morris has investigated failures involving line pipe, fittings, fabricated components, girth welds, fabrication welds, prior repairs, and flanged connections. As an AWS Certified Welding Inspector, he has qualified welding procedures and welders for both new construction and maintenance (e.g., in-service) welding applications. Mr. Morris has developed relative risk ranking models for both liquids and gas pipeline operators, including enhancements of the Kiefner-NGA risk model to incorporate additional threats and threat interaction. Mr. Morris is an active member of API Subcommittee 5, which maintains API 5L. Previously, he was a member of the Task Group of ASME Subcommittee F that developed the first edition of the ASME B16.49 Standard for induction bends. Additionally, Mr. Morris has taught courses covering various topics, such as pipeline reliability assessment, fracture mechanics, defect assessment methods, and pipeline repairs.
