During his time at E2G, Mr. O’Brien has worked extensively with REAC and overhead systems. This work has included written inspection plans, special emphasis mechanical integrity programs, wash water injection design, and CML optimization. He has performed multiple risk assessments for air coolers, including those constructed of duplex stainless steel. Mr. O’Brien possesses an in-depth knowledge of damage mechanisms commonly affecting the refining and chemical industries, which he uses to perform high-quality laboratory failure analyses and conduct P&ID level corrosion reviews. Mr. O’Brien has developed models for HTHA, minimum pressurization temperature (MPT), creep embrittlement, and temper embrittlement. He managed a joint industry project (JIP) to improve detection and characterization of early stage HTHA damage.Mr. O’Brien also worked at Andeavor, where he conducted corrosion reviews of equipment, analyzed inspection data using risk-based inspection (RBI) mechanical integrity software, and authored procedures for the inspection of cooling water towers and failure analysis of fixed equipment. As a process engineering intern at OMNOVA Solutions, Inc., Mr. O’Brien designed a minimum flow loop for a raw material storage tank, generated management of change and temporary work instructions according to process safety management standards, lead cross-functional groups to perform incident investigations for both safety and quality issues, wrote standard operating procedures for production processes, and completed routine inspections of safety equipment.
