API 650/620 Tank Secondary Containment Issues
(OP)
Guys,
I'm running into some resistance when I try to justify why I do not want electrical/process equipment inside the dike walls around tanks. We need a run down cooler to cool some condensate and
"they" want to place these coolers inside the dike. Every site I have worked this has not been done, and looking through API 650 and RP 500 I cannot seem to find a justification to prevent this. Is this practice just a good plant construction rule of thumb or is there a standard I can fall back on? Thanks for your experiences and your input.

*At Fukushima, the intakes for the emergency diesel generators ended up below the high water mark. Thus started the disaster.

Which NFPA standard are you siting? (Also, "they" are banking on Class 1 Div 2 electrical for protectation; as a caveat).

API & NFPA allow placing motors 'on the ground', just not below hydrocarbon level inside a containment.
BTW, using a vertical-shaft pump and placing the motor above the top of the dike is good engineering -- I'll be stealing that idea. Thanx!
