Engineering certainty in severe sour service
from Pipeline Innovations TechTalk Hosted by Gulf Podcast Network
This episode examines severe sour service, one of the pipeline industry's most technically demanding challenges. Pipeline & Gas Journal sat down with Calum MacLean, Head of Welding Engineering, and Tom Feteris, Offshore Director, both of CRC Evans, to discuss why rising hydrogen sulfide (H₂S) concentrations, deeper water and harsher operating environments are pushing operators toward more experienced engineering partners. The conversation covers what separates severe sour projects from conventional pipeline construction, including metallurgy, hydrogen effects and long-term material integrity, and why success depends on early engineering engagement rather than a single qualified welding procedure.
