Engineering Design and Thermal, Stress, Vibration and Fatigue Analysis

Design & Analysis

Performing engineering design, analysis and troubleshooting to codes including AWS, API and ASME (B&PV, Piping and BTH) – ensuring structural integrity of pressure vessels, heat exchangers and other process equipment.

Whether it requires closed-form Design-By-Rule methods (such as ASME Section VIII Division 1) or finite element analysis and Design-By-Analysis (such as ASME Section VIII Division 2) – we have extensive experience in the design, analysis and optimization, maximizing equipment reliability and controlling costs for owner-users. A few examples include:

  • Design and analysis of pressure vessels, heat exchangers and process equipment
  • ASME B&PV Code design and analysis of feedwater heater
  • ASME Power & Process Equipment (B31.1 & B31.3) analysis
  • Heat transfer & thermal transient analysis of equipment
  • Optimal design for weight, strength and durability
  • Seismic and structural analysis of skids and related equipment
  • Vibration and fatigue analysis of components including bellows
Clamp FEA Model
FEA Analysis of Vessel
Analysis of Vessel Head

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, due to temperature differences. We thus designed a series of clamps to seal the two pieces together.
