Leakage issues in "1908(113 years old) Riveted Tank"

Leakage issues in "1908(113 years old) Riveted Tank"

thread809-473593: Leakage issues in "1908 Riveted Tank "

Hello Seniors!

Reference to my last thread809-473593: Leakage issues in "1908 Riveted Tank ".I thought to end the previous thread but it had been closed already.
But now I am ending it now with the latest updates regarding the issue.

So we were somewhere near two options.
1>To patch weld all the rivets from inside and then paint application.
2>To remove the roof(newly installed) and replace all the remaining shell courses one by one.

But we went for 2nd option with some changes that we started removing shell course(from 2nd shell course)and installing new plates one by one. We completely welded all the new plates. During all these activities roof and old shell courses were temporarily supported by beams and channels. After completion, hydrotesting was performed and there were no leakage as now the tank has been completely replaced by the new one.

Now client is happy and contractor as well. Win-win situation for all.bigsmile
Here are some pics of Tank-435 before and after completion.

So, first you have replaced the the bottom plates, 1st shell course, and roof ...

Then , you have provided temporary support and scaffold to the new roof and replaced the other shell plates one by one..
...Now you say , everybody is happy and Win-win situation for all ..

If you could have gone for a new tank at the beginning instead of changing all the parts in installments , probably everybody will be more happy ???

I think that we all have learned something from your experiences and decisions ...

For more third world guidance on piecemeal tank repair, see this seminal technical book:

Yes sir, construction of a whole new tank option was feasible but there were some restrictions.
So we approached in this manner.

Sir you have deleted your reply,
I think you have understood what i have described here.

Thanks for posting a final update. So many interesting question on this site generate lots of answers, but no final resolution.

I've also had customers insist on extensive repairs to avoid full replacement of an ancient tank. Often because repairs come from the large maintenance budget whereas as a new tank would have to come from the limited capital expenditure budget.
