LecturersDr. Raymond R. Fessler worked on the Pipeline Research Committee project on SCC since its inception in 1965. He personally conducted most of the early field investigations of SCC, from which he identified the major factors that cause high-pH SCC in pipelines. He also managed the laboratory portion of that program from 1965 to 1982, which added significantly to an understanding of the phenomenon and explored a number of possible solutions to the problem. For the past several years, he has been the SCC consultant for GRI and PRCI. He recently completed a comprehensive gap analysis on SCC, and he actively participated in drafting the NACE Recommended Practice on SCC Direct Assessment.

This work led to the discovery of near-neutral pH SCC and identified the conditions under which it occurs. He also served as Chair of the PRCI’s SCC Subcommittee for two years.
