The hydrocarbon processing industry (HPI)
uses large storage tanks to manage inventories of raw materials
and finished products (Fig. 1). Various international codes
define design parameters to ensure the safe and efficient
operation of aboveground storage tanks (ASTs). This article
discusses specific requirements for petroleum tank-farm bund
wall sizing, plot area and associated costs for larger storage
facilities (100,000 m3
plus) for ASTs with operating pressures <17 kPa (2.5 psig).

aboveground storage tanks and bund.
Various international codes provide
recommendations for a tank-farm bund wall height and volume to
be contained. Some recommendations are made to optimize safety.
The requirement of AS1940/ SS CP40 of bund volume limits of
60,000 m3 for fixed-roof and 120,000 m3
for floating-roof tanks are analyzed in greater details.
