What is CAESAR IIĀ®

CAESAR II evaluates the structural responses and stresses of piping systems to international codes and standards. CAESAR II is the pipe stress analysis industry standard against which all others are measured.

 

CAESAR II enables quick and accurate analysis of piping systems subjected to a wide variety of loads (including weight, pressure, thermal, seismic, and other static and dynamic conditions) following more than thirty-eight international piping code standards, and many environmental and equipment guidelines.

Overview

Why use CAESAR II?

CAESAR II is used for a variety of reasons, but mainly because Owner operators mandate its use to check that the piping designed for their facility after it is commissioned and operational is going to be operate reliably and safely. CAESAR II is usually mandated due to its maturity, calculation accuracy, and ability to cater to the analysis requirements of many different projects in many industries, ensuring piping is certified in accordance with the design codes and standards that

apply wherever an industrial facility resides in the world.

Who uses CAESAR II?

CAESAR II is a renowned software application for pipe stress analysis. Extensively used by engineers and designers to evaluate the structural response of piping systems to various loads and ensure their safety, compliance, and reliability.


EPC companies and Owner operators worldwide use CAESAR II for analysis of piping systems found in their offshore and onshore projects.

Benefits of CAESAR IIĀ®

Renowned Software:

Software internationally recognised by EPCs, Owner operators, and Notified Bodies.

Comprehensive Pipe Stress Analysis:
  • Static and Dynamic Analysis: CAESAR II allows users to perform both static and dynamic stress analyses, accommodating a wide range of load conditions, including thermal expansion, pressure, seismic, wind, and other dynamic forces. This comprehensive approach ensures that all critical aspects of piping stress are evaluated.


  • Nonlinear Analysis: The software supports nonlinear analysis, accounting for large displacements, nonlinear restraints, and other complex behaviours in piping systems. This capability allows for more accurate modelling of real-world conditions.
Compliance with International Standards:
  • Standards Support: CAESAR II supports a variety of international piping codes and standards, including ASME, ISO, EN, B31.1, B31.3, and many others. This ensures that designs meet regulatory and safety requirements specific to different regions and industries.


  • Automated Code Compliance: The software automatically checks for code compliance, providing engineers with insights into stress levels, allowable limits, and potential areas of concern.
User-Friendly Interface:

• Intuitive Modelling Environment: CAESAR II features a user-friendly interface that simplifies the modelling process. Engineers can quickly create models using graphical input, reducing the learning curve, and increasing efficiency.


• 3D Visualization: The software provides 3D visualization capabilities, allowing users to view and interact with piping models. This visual representation aids in understanding complex piping configurations and identifying potential issues. Evaluation of stress analysis results is made easier though cutting-edge graphics that are highly responsive and performant during model creation, manipulation, and viewing. Graphical animation of results aids decision making and problem resolution.


Advanced Load and Support Modelling:

• Flexible Load Modelling: CAESAR II enables the modelling of various load types, including thermal, pressure, dead weight, live load, and occasional loads. Users can define load cases and combinations to simulate real-world conditions accurately. Comprehensive definition of load cases supported by a dedicated editor, ensuring all conditions that the piping is subject to, are considered and evaluated.


• Support and Restraint Options: The software offers a wide range of support and restraint types, including spring hangers, snubbers, and anchors. Engineers can model these elements to reflect actual support conditions and optimize the design.


Integration with Other Software:

• Interoperability: CAESAR II integrates seamlessly with other Hexagon products facilitating data exchange and collaboration across disciplines. Bi-directional integration with CADWorx Plant Professional reduces risk of errors and costly iteration time between plant piping design and stress analysis disciplines, enhancing workflow efficiency and reducing data duplication.


• Data Import/Export: The software supports data import and export from various CAD and engineering software, allowing for easy data transfer and collaboration with other teams and stakeholders. An Advanced PCF interface supports import of piping models from a variety of piping and plant design systems.


• Integration with GT STRUDL: Possible via CIMSTEEL CIS/2 or GT STRUDL .GTI, enables sharing of load details, post-analysis, ensures pipe stress analysis and civil/structural groups work together without duplicating information and effort.


Detailed Reporting and Documentation:
  • Comprehensive Reports: CAESAR II generates detailed reports that include stress analysis results, load cases, deflection, restraint forces, and other critical data. These reports are essential for documentation, review, and compliance verification.

  • Customizable Output: Users can customize report formats and output to meet specific project or client requirements, ensuring clear communication of analysis results.
Enhanced Design Optimization:
  • Iterative Design: Engineers can perform iterative design analysis to optimize piping systems for cost, weight, and performance. By adjusting parameters and rerunning analyses, users can find the most efficient design solutions. An in-built Loop wizard tool automates and optimises expansion loop designs saving time and material cost.

  • Vibration Analysis: CAESAR II allows for vibration analysis, helping engineers understand how changes in parameters affect system behaviour and identifying critical factors in design decisions.


Accurate Simulation of Real-World Conditions:
  • Temperature and Pressure Effects: The software models accurately temperature and pressure effects on piping systems, accounting for thermal expansion, contraction, and stress due to pressure fluctuations.
  • Vibration and Fatigue Analysis: CAESAR II can evaluate vibration effects and fatigue life, helping to prevent failures due to cyclic loading and dynamic forces.
  • Inclusion of B31J Piping Code: Reduce piping design and analysis time, and more importantly, construction and lifecycle maintenance costs
  • Design Assistance: Load flange data for analysis of equipment connections in accordance with EN-1591 and other standards.
  • In-built Error Checking: Analysis can only be performed when piping models and data are completely and accurately defined, otherwise CAESAR II reports errors appropriately indicating what’s missing and needs to be corrected before analysis can continue.
Advanced Material Modelling:
  • Material Libraries: CAESAR II includes extensive material libraries with data on material properties, including temperature-dependent properties. Engineers can select appropriate materials for their designs or define custom materials if needed.

  

  • Creep: The software considers creep effects in materials, particularly for high-temperature applications, ensuring long-term reliability and safety.
Industry Applications:
  • Oil and Gas: CAESAR II is widely used in the oil and gas industry for designing and analysing complex piping systems in refineries, petrochemical plants, and offshore platforms.
