New API 650 Seismic 4

[IFRs]

I understand that the up-coming edition of API 650 has a completely re-written appendix E (seismic). Does anyone out there know how the new results will compare (higher or lower) to the old results?

In addition to a completely new format, the loads are generally a bit higher in a lot of places.

RE API 650 has a completely re-written appendix E (seismic) is a draft for review available.

Isthill,
A new API-650 is being drafted, but it is still an internal document for API subcommittee activities only. A public copy is not available.

Knowing that the committees are very sensitive to the impact of code revisions on the member companies, I assume that comparative calculations have been run for a variety of cases between the old Appendix E and the new one. Can the results of these studies be shared?

You can view the new API 650 at the following location:

http://committees.api.org/standards/cre/scpvt/refdocs/docs.html

There is a line near the bottom that reads:

PIP/API 650 Draft 79, dated October 5, 2005

It is not underlined as a link, but if you click on it, it will offer you the option to download the code.

Keep in mind this is a draft document and should not be used for design purposes until it is published.

Hope this helps.

The new API 650 has been released for public purchase.

Can you provide a link because I can't seem to find it on their website.

Thanks
