Design & Analysis

Performing engineering design and analysis – (thermal, stress, vibration and fatigue analysis) to codes as 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 (ANSYS) finite element analysis and Design-By-Analysis (such as ASME Section VIII Division 2) – we have extensive experience in the design, analysis and optimization of equipment, 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) design and 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.

    In addition to engineering design and analysis, we also provide troubleshooting, repair and life extension services to codes and standards including API 579 (Fitness-For-Service), NBIC (National Board Inspection Code), API 510 (In-Service Inspection, Rating, Repair), API 570 (Piping Inspection Code: Inspection Repair, and Re-rating of In-service Piping Systems), and API 653 (Tank Inspection, Repair and Reconstruction).

    Fatigue evaluations are performed per ASME Section III Class 1 and Section VIII Division 2. The fatigue design life evaluation procedures in Section III of the ASME Boiler and Pressure Vessel Code were originally developed in the U.S. Naval Nuclear Program. Those involved were Bill O’Donnell, (Bernie) Langer, W.E. (Bill) Cooper and James (Jim) Farr – who, in the late 1950’s and early 1960’s developed the initial formulation of this technology in the Tentative Structural Design Basis for Reactor Pressure Vessels and Directly Associated Components, which became known as “SDB-63.”

    Section III of the ASME Code “Vessels in Nuclear Service” was the first to include specific Code rules to prevent low cycle fatigue failure. Its first edition was published in 1963; Section VIII, Division 2, “Alternate Rules for Pressure Vessels” followed in 1968.
