Vibration Troubleshooting, Analysis and Repair

We provide vibration troubleshooting, testing and analysis services – performing design modifications on equipment, ensuring structural integrity, minimizing risk and controlling costs for owners/users.

Most equipment vibration problems are due to thermal, mechanical, acoustic, or flow related excitation – and if left unchecked, will cause equipment failure, which may lead to greater repair costs. Components vibrate at particular natural frequencies. These frequencies and resulting mode shapes can be determined using vibration and modal analysis. Often, simple analysis can be performed, while for more complex systems, finite element analysis is performed to determine to determine the dynamic response.

  • Vibration troubleshooting, analysis and repair of equipment including compressors, fans, shafts, and piping
  • Vibration and seismic analysis of tanks, vessels, skids and welded structures
  • Vibration and shock analysis of nuclear equipment in land-based and shipboard applications
  • Recent Projects

  • A vibrating component or system often leads to fatigue – which eventually causes equipment malfunction, or catastrophic damage. Fatigue cracks usually initiate at the surface, and for this reason, the condition of the surface and the environment are important factors influencing fatigue behavior. 

    Tom O’Donnell has performed vibration, fatigue and failure analysis, and Bill O’Donnell Sr. currently serves as the Chairman of the Subgroup of Fatigue Strength of the ASME Boiler and Pressure Vessel Code. 

    Examples Include:

    • Compressors
    • Welded Assemblies
    • Supports
    • Lifting Devices
