MasterFlex,

My opinion is that stating the 'Code Edition' that your version of CAESAR is supports is the wrong answer.

What you need to know is, what is the 'Code of Record' for your project and that you are following that regardless of what 'Code Edition' your version of CAESAR uses.

'Codes of Record' are usaully the Code Editions that are in effect at the time the contract is signed at the beginning of the project. Many times the code editions are listed in the Project Contract, Project Execution Plan or other project documents issued by your company or the client.

You should also have a 'Pipe Stress Criteria' issued specificly for each project. In addition to re-stating the Codes and the edition of the codes that you are using, it should also outline the following:

1. Your scope, what you are going to review and what you are not, what will be by computer etc.
2. Outline your deliverables so there is no misunderstanding later.
3. Address the Wind and Seismic criteria.
4. Address transport and Motion Accelerations for floating platforms if applicable.
5. etc. etc.

Back to the 'Code of Record' discussion, you should be doing two things.

1. Checking that CAESAR is using the correct stress values and properties for your material.
2. And if not, manually modify your input to reflect the correct values.

CASEAR may not be wrong, but may just be using values from a different code edition than what your project is using.

This is YOUR resonsiblity and not COADE's.

Knowing and using the "Code of Record" for your project is important. Switching to the latest code edition mid-project may get you in trouble if stress values or flange ratings get revised.

That's my 2¢...
