API 653 and Storage Tank Inspection
API 653 and Storage Tank Inspection
(OP)
API 653 provides the owner-user a fair amount of latitude re: the extent of inspection that is done on aboveground atmospheric storage tanks. I'm curious how folks have used their local experience to come up with the extent of inspection that is actually done on particular tank shells and bottoms, and how they prioritize which tanks are inspected and when. Any info. that could be shared would be appreciated. Thanks.





RE: API 653 and Storage Tank Inspection
Also the results of the inspection need to be evaluated by a competent engineer experienced in the design of storage tanks (or pressure vessels or piping, given the situation)
It has been my experience that many companies simply hire an API-653 inspection, and no thorough evaluation is performed.
Unfortunately, I'm not sure whether I can leave me email address or my company's web site to give you more information
RE: API 653 and Storage Tank Inspection
As far as priority based on internals, one suggestion would to perform externals on the shells and roof. Pay particular attention to the bottom shell course, external ring and sump area for signs of corrosion. Then set a priority based on the corrosion rates of these components.
An alternative would be looking into accoustic emmissions?
