Nathan Libertowski: About the Author
Engineer II, The Equity Engineering Group
Nathan Libertowski is an Engineer with the Rotating Equipment, Vibrations, & Dynamics (REVD) Team. Prior to E2G, Mr. Libertowski was a Graduate Research Assistant at The Ohio State University, where he worked at the Turbine Aerothermodynamics Lab and studied particulate deposition relevant to gas turbine engines. There, he designed experiments to validate, improve, and add physics to the OSU Deposition model. At E2G, Mr. Libertowski has been involved in multiple piping vibration and API 579 FFS projects. In these projects, he collected vibration data in-field and performed FEA, as well as piping flexibility analyses, to pass or fail the piping systems. If the system failed, creative support designs or vibration mitigation techniques were suggested to reduce the vibration.
