Tank shell plate replacement
Tank shell plate replacement
(OP)
Hello everyone.
I will have to replace 3 entire shell plates of our naphta tank. They are side by side in the third level out of six.
Where can I find information how I have to procede, the correct sequence of each step.
Appreciate your comments/thoughts on the above.

But if you follow the [very conservative] rules of API-653, you will have a safe tank.

A ridiculous as it might sound you might want to consider complete removal of the top three rings and rebuild from there. At least you still have the base, bottom two rings and nozzles. API 650 tasks are highly stressed and very thin compared to diameter and not designed to allow this sort of repair without serious reinforcement during the work. An alternative might be replacing your three plates with many more smaller ones one at a time...
You need the tank guy the others are talking about.

Why do you want to replace only a few sheets up high on this tank ?
My experience has been, usually only the bottom and bottom course of many tanks corrode away.
Replacement is typically done to the bottom of the tank
( Note: Concentrated sulfuric acid is an exception to this rule)
What is causing the problem with your naptha tank ??

We still don't know exactly what happen to the tank. We are checking out some companies to get the job done.

While I agree that CB&I is a competent tank contractor, they are not the only one. There are several other tank contractors that may be able to offer a competitive advantage. Those of us on here who work for one of the other competent contractors with an excellent safety record appreciate being included in such listings.
Apart from that, I think your point is spot on.

However, I don't think that GUIBAR could go wrong asking Phil Myers (www.pemyconsulting.com)to consult on this project.
