Storage Tank Inspection
Storage Tank Inspection
(OP)
I was looking for some general information on procedures for inspecting above ground storage tanks (motor oil and transmission fluid), oil/water traps and pipes. They have already completed an environmental inspection. This inspection would be for cracks, broken pipes, crumbling mortar or other conditions.
Some background:
We were asked to inspect some storage tanks for an Car dealership/service center. I am not sure if we will take the assignment or possibly involve another firm however I would like some information either way.
Do you pressurize the pipes/tanks and check for pressure drop? How do you plug the lines? Or would this be unnecessary as the environmental report would show such leaks?
Check for cracks or signs of stress?
Would there be a manufacture that would have some good information to look at?
Also I'm not exactly sure what 'other conditions' one might expect.
The environmental report found trace levels of certain substances but only found a recordable amount of a substance (I will need to reread the report) at one trap location.
Thanks!

RE: Storage Tank Inspection
I would assume that the #1 issue is corrosion.
RE: Storage Tank Inspection
We may need to hire an inspector but I would be interested in what the inspections involve. I will look into your references. These would be smaller tanks (I believe) 500 gallons or less.

RE: Storage Tank Inspection
Just out of curiosity -
1.) What would you say an inspection/report costs for (3) above ground storage tanks?
2.) There are 3 water/oil traps would they inspect these as well?
3.) You mentioned corrosion is a concern. What else can be expected as part of the inspection? Is it mostly visual, is there any analyse or calculation run, mostly based on experience?
Thanks again.

RE: Storage Tank Inspection
Tanks will have to be blanked and/or disconnected, cleaned, and ventilated to be ready for safe entry, and adequate inspection.
Water-oil traps, if external to the tank(s) are a separate issue and not covered by STI or API tank codes. Probably have to make separate arraingements with the Inspector.
