Design and Structural Analysis

Engineering Analysis - O'Donnell ConsultingWe perform design and structural analysis including thermal, stress, vibration and fatigue analysis. Our work has included:

  • Design of pressure vessels, heat exchangers and process equipment
  • Thermal transient analysis of equipment
  • Seismic and structural analysis of skids and related equipment
  • Instability analysis of support structures
  • Vibration analysis of piping, steam generators, control valves, and other process equipment
  • Design and analysis of components to ASME B&PV Code – including B16 and B31
  • Analysis of structures to API, AWS and AISC Code

Pressure Vessel
Clamp on Pressure Vessel

O’Donnell Consulting Engineers performed the design and analysis of elevated temperature / pressure vessels. One particular vessel had to operate under a no-leak condition. The challenge was to attach the hemispherical head to the shell without causing distortions, because of temperature differences. We thus designed a series of clamps to seal the two peices together.

Our expertise includes equipment operating in vibration and elevated temperature environments. We have taken on challenges in a spectrum of industries including energy, aerospace, mining, transportation, materials handling, and manufacturing.
