Mr. Libertowski is a Staff Engineer with the Rotating Equipment, Vibrations, & Dynamics (REVD) Team at E2G | The Equity Engineering Group, Inc. He has been involved in multiple piping vibration and API 579 FFS projects. In many of these projects, he collected vibration data in-field and performed dynamic FEA to determine the severity of the vibration. If required, creative support designs or vibration mitigation techniques were suggested to reduce the vibration. Mr. Libertowski is also a member of ASME and is Category III vibration analyst certified.
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.
