Pressure vessel design and analysis including nozzles, supports and appurtenances. This includes stress, thermal, seismic/ vibration and fatigue analysis to Engineering Codes as AWS, API and ASME B&PV – ensuring vessel structural integrity.

We have extensive experience in closed-form Design-By-Rule methods (ASME Section VIII Division 1) and finite element analysis with Design-By-Analysis (ASME Section VIII Division 2). This includes:

  • Pressure Vessel Design and Analysis to ASME B&PV Code
  • Independent Design Reviews – Pressure Vessels, Nozzles & Supports
  • Recertification Analysis of Aging Pressure Vessels
  • Fatigue Analysis of Vessels used to Produce Hydrogen
  • Design & Analysis of Pressure Vessels Operating at Elevated Temperatures

Division 1 (Design by Formula) is a simple approach, using equations that produce a robust and proven conservative design. This approach works best on design of simple vessels, without any extreme geometric discontinuities (such as nozzles).
Division 2 (Design by Analysis) is often done with the use of finite element modelling to accurately predict stresses in complex vessels. This method provides room for reducing material usage while maintaining structural integrity.
