Hello, Shukla.

We have aware about your point few years back and did request clarification from Coade.

Mr. Mandeep replied : I would also tell you that the saddle baseplate analysis based on traverse load per Moss is quite conservative. In my opinions, you can disable the saddle baseplate analysis for the transport case.

This huge base plate thickness will be concluded when uplift occurs due to strong transverse load like wind or transportation acceleration (say on a FPSO).
Using concept by Moss, the modulus used to compute bending stress solely depend on rectangular cross section of base plate.As you said, contribution from ribs and web are excluded.

May be this is what Mr. Mandeep meant by "conversative" and his advise is to disable calculation of base plate for transportation case. Seems to be no permanent solution to provide clean report unless increase base thickness to un-releastic figures.

Wish Ray can share the reply after study via this forum discussion.
