This is a pipeline breakout facility in El Paso (just north of Ft. Bliss). Fine sands followed by caliche and medium grained sands, in turn underlain by gravel. I don't think we need to worry about hurricanes. You are not THE FOCHT from Mclelland Engineers, are you?
The site is in Texas. N values are from 14 to 20 all the way down to gravel at 60 feet. Fine silty sand is encountered from 0 to 14 feet. Medium grained sand from 14 to 60 feet. Height of the tank is 60 feet. As for settlement, the client is still debating the issue with their engineers...
Thanks very much. I not only found API 650 but also found Duncan and Orazio's paper on stability of oil storage tanks. Found them both to be very useful.
A client wishes to construct a tank farm (ten 80-ft diameter tanks) on silty sands. The fine sands (medium dense) extend all the way down to 60 feet from ground surface. The client wants to place the tanks directly on the sands without footings. Does anyone have any experience doing this...
