New Inspection Techniques in Tanks Aboveground

New Inspection Techniques in Tanks Aboveground

Hi All
A tank of Height 60' and Diameter 200'. It is insulated and it will be inspected for roundness and plumpness.
A bulge is expected to be detected through internal inspection.
Do you know about the latest inspection techniques to be used and those companies capable to carry out such inspection?
Once the tank is open and we get inside, how to assess distortion at inspection time.

I have heard about a new technique as laser scan, which can give me the internal profile of the tank in order to know the existence of bulges, dents and so.

My understanding is that an internal settlement survey should be mandatory as part of inspection.

It is great to know this forum is growing up.

Thank you in advance for your help.!!

You can have a verticality survey performed on the shell via a laser level type device.  It measures and compares the shell at 3 points on each shell course at equally spaced measurements around the tank; with the main aim at being at points straight across from each other.  This, of course, would require finding someone in your area that does this and can give you a proper accessment on the findings.  You can also use the old school method of measuring the plumbness of the shell by utilizing a plumb pole, but depending on the wind speed, it may be best to perform this technique internally.

"Plumbness or plumpness"...????

I think one technique is used to evaluate storage tanks.... the other to evaluate people at a bar...
