A study of corrosion in steel fuel storage tanks, which failed after several years of operation highlighted intense pitting and microbiological corrosion. Significantly higher corrosion rates were found than would be expected with normal seawater corrosion. Therefore, the established methodology for predicting the remaining service life of tanks is also questionable. The aim of the study was to evaluate the actual corrosion rates at the bottom of the petroleum product tank. For this purpose, we adapted the established laboratory methods for evaluating the corrosion rate to perform field measurements. The observed corrosion rates in the tank are higher than the currently known values.
