1. Specialized Pressure Vessel Design (Code Calculations)

• COMPRESS (by Codeware):
  • Status: Industry Standard.
  • Function: Comprehensive design and documentation. It generates calculation reports, fabrication drawings, and data reports automatically.
  • Best For: Full vessel design compliance and documentation.
• PV Elite (by Hexagon):
  • Status: Industry Standard (Main competitor to Compress).
  • Function: Similar to Compress, widely used for vertical towers, horizontal vessels, and heat exchangers. Strong integration with Hexagon’s analysis tools.
  • Best For: Tall towers and complex exchanger designs.
• Nozzle PRO (by Codeware):
  • Function: Specialized Finite Element Analysis (FEA) for vessel nozzles and junctions.
  • Best For: When standard code formulas (WRC 107/297) are insufficient, and detailed stress analysis of the nozzle-to-shell junction is required (ASME Sec VIII Div 2 Part 5).
• HTRI Xchanger Suite:
  • Function: Thermal design and rating of heat exchangers (which are a subset of pressure vessels).
  • Best For: Shell & Tube, Air Cooler, and Plate exchanger thermal performance.

2. General Finite Element Analysis (FEA)

• ANSYS Mechanical:
  • Status: The Gold Standard.
  • Function: Structural, thermal, and fatigue analysis.
  • Best For: Complex stress linearization, thermal gradients, and fatigue life assessment.
• Abaqus (by Dassault Systèmes):
  • Function: Highly advanced nonlinear analysis.
  • Best For: Complex contact problems, plasticity, and dynamic loading.
• SolidWorks Simulation / Autodesk Inventor Nastran:
  • Function: Integrated FEA within the CAD environment.
  • Best For: Preliminary analysis and simpler vessel components.

3. CAD (Computer-Aided Design)

• SolidWorks: Very common in small-to-mid-sized fabrication shops. Easy to learn and use.
• Autodesk Inventor: Common in industrial machinery and mid-range vessel design.
• Siemens NX / CATIA: Used in large-scale engineering, aerospace, and nuclear industries where surface modeling and massive assemblies are required.
• AutoCAD: Still widely used for 2D drafting, P&ID markups, and quick sketches.
• AVEVA E3D / PDMS: Used in large oil & gas EPC (Engineering, Procurement, Construction) projects for plant modeling.

4. Piping & Plant Integration

• CAESAR II (by Hexagon):
  • Function: Pipe stress analysis.
  • Relevance: Vessel engineers use this to check nozzle loads imposed by connected piping to ensure they don’t exceed API 610 or ASME limits.
• SmartPlant 3D / AutoCAD Plant 3D: For modeling the vessel within the context of the entire process plant.

5. Essential Productivity & Data Tools

• Microsoft Excel:
  • Reality: Despite advanced software, Excel is still heavily used for custom calculations, cost estimation, material take-offs (MTO), and quick “back-of-the-envelope” checks.
  • Skill: Proficiency in Excel (including VBA/Macros) is often expected.
• Bluebeam Revu:
  • Function: PDF markup and collaboration.
  • Relevance: Used extensively for reviewing vendor drawings, redlining fabrication drawings, and managing document control.
• PLM/PDM Systems (Windchill, Teamcenter, Enovia):
  • Function: Managing revisions, bills of materials (BOM), and workflow approvals.

6. Material & Corrosion Databases

• MatWeb: For looking up physical properties of materials (yield strength, thermal expansion) at design temperatures.
• Corrosion Handbook / NACE Resources: For selecting materials based on the process fluid environment.

Summary: The “Ideal” Software Stack

1. Must-Have: COMPRESS or PV Elite (You cannot design code vessels efficiently without one).
2. Must-Have: SolidWorks or Inventor (For 3D modeling).
3. High Value: ANSYS (For FEA/Div 2 design).
4. High Value: Excel (Advanced proficiency).
5. Nice to Have: CAESAR II (Understanding nozzle loads).

Important Note on Codes

• ASME Boiler and Pressure Vessel Code (BPVC): Section VIII (Div 1 & 2), Section II (Materials), Section V (NDE), Section IX (Welding).
• PED (Pressure Equipment Directive): For Europe.
• CRN (Canadian Registration Number): For Canada.
• API Standards: (e.g., API 650 for tanks, API 660 for exchangers).

Design of Pressure Vessels

This intensive course is aimed at engineers developing pressure vessel designs, it covers the requirements of the PED and the three main design codes used in the UK – PD5500, ASME VIII Division 1 and EN 13445. Starting with an introduction to the pressure vessel concepts it covers all basic design considerations, including: joint efficiencies, heads and cones under pressure, nozzles and openings, flat ends, bolted flanged connections, supports and local load analysis. At the end we look at the considerations to do with the transportation and installation and other practical considerations.
