jharris3,
I strongly agree with you that a monkey with a tool is still just a monkey. I appreciate your valuable advise.
Can anyone pls share your experience of using COMPRESS to design fatigue vessel?

I have a gas processing unit mounted on a giant ship. The vertical vessels (100' tall, 12' Dia) mounted on modular epxperiences waving angles with ocean waves. This vessel is filled with half liquid. Question:
1. How can supplier design this vessel per Div. 1?
2. Is this vessel to be considered...
For fatigue service reason, we call out vessel material to be normalized SA 516-70, and elipse heads (min thickness 2") get to be hot formed. The vessel fabricator proposes to use normalized plates to hot form the elipse heads and normalize the heads after.
My concern is if the mechanical...
r6155,
It's clear that elipse heads need to be normalized. Vessel fabricator is to use normalized plate to cold form the elipse head and thereafter normalize the head again. My concern is that if twice normalizations cause negative impacts to material mechanical properties. I will feel much...
Thanks, James.
I expected MTR from mill includes normalization simulation test results (2 cycles min), not from head former. I know most mills provide PWHT simulation test results, but not sure if majority mills provide normalization simulation test.
My understanding is that multiple...
Jamesl,
The MTR actually is provided by mill without normalization simulation test, not by head former. As i said, I like to see normalization test results of two cycles simulation since head material actually experiences twice normalization.
