Assessment

CAESAR II by another name and still the reference for pipe stress analysis. Its ubiquity among stress engineers and reviewers is itself a decisive advantage.

  1. Capability25%9/10

    Static and dynamic pipe stress analysis with nozzle, flange, buried and subsea piping checks against international codes.

  2. Interoperability20%8/10

    Imports models from many plant design tools via PCF and exchanges data with Forte 3D, Forte 3DWorx and Aspect Pressure Vessel.

  3. Scale15%9/10

    Used on piping systems of every size across process, power and offshore projects.

  4. Usability15%7/10

    Long-familiar workflows for stress engineers worldwide.

  5. Deployment10%6/10

    Desktop software.

  6. Ecosystem15%10/10

    Sold for decades as CAESAR II and the most widely recognised pipe-stress program in the industry.

Strengths

  • Broad code coverage
  • PCF import from many design tools
  • Industry-wide familiarity

Considerations

  • The new Octave name will take time to settle in specifications
  • Desktop only
  • Licensing per seat
