CE on FOUNDATION CONTAMINATED BY PRODUCT - CRUDE OIL

By: CE [1592] 1 Stars

Dear Tank Experts,

A happy new year wish to you all.

Case:
I have a situation with one of my jobs. It is a crude oil storage tank. Had its Single deck floating roof collapse that punctured the bottom plates and the product have seeped through the punctures. During inspection, we noticed oil weeps from underneath the annular plates from the tank external.
Questions:
1. How can the foundation be inspected.
2. What code do we refer for detailed tank foundation issues?
3. Oil contamination on foundation, what does it cause?
4. If confirmed contaminated by any code/standard, what is the repair/remedy procedure?

I appreciate your usual assistance with these.

Also any other useful infor will be appreciated.
I have just completed hydrocutting the roof and discovered the holes on the bottom plates.

Thanks,
