Can the esteemed forum members kindly help me on the following:

1) Reference ( any code, paper etc)on subsea pipe analysis which specially addresses the issue of upheaval buckling.I only know of a Shell DEP refernce on this issue .

2) Paper by K.Peters on lateral and upheaval buckling of buried pipelines.

Kind help will be highly appreciated.

Best Regards

I am not too sure whether this will help you or not, you may try to look at these codes.
