Overview:

Mr. Prueter is a consultant in the chemical, petrochemical, and nuclear industries, performing Fitness-For-Service (FFS) and design evaluations of equipment using the rules of API 579-1/ASME FFS-1 and the ASME Boiler and Pressure Vessel Code. He also uses non-linear Finite Element Analysis (FEA) to support FFS and design evaluations.

Mr. Prueter specializes in pressure component design, FFS, static and dynamic computational techniques, transient thermal-mechanical fatigue analysis, elevated temperature creep and creep-fatigue simulations, and fracture mechanics using analytical and computational techniques. Currently, Mr. Prueter’s responsibilities include leading the Advanced Analysis Group and managing Nuclear Consulting Services. He is a Registered Professional Engineer in nine states and qualifies as a Specialized Registered Professional Engineer (RPE) per the American Society of Mechanical Engineers, Boiler & Pressure Vessel Code, Section III, Division 1, Mandatory Appendix XXIII and can provide certification of nuclear Design Reports on behalf of the N Certificate Holder. Additionally, he is a member of the ASME Section VIII Working Group on Design by Analysis (WG-DBA) and Subgroup on Elevated Temperature Construction (SG-ETC).

Prior to joining the Equity Engineering Group, Mr. Prueter was a graduate research fellow in the Dynamics and Vibrations Laboratory at The Ohio State University. His research involved using advanced finite element and contact mechanics techniques to analyze the design and vibration characteristics of gear drive systems and rotating equipment. Mr. Prueter also has experience in the nuclear industry, performing thermal, mechanical, and fatigue analyses on steam generation components for government nuclear power plants.
