• The usable tank capacity is reduced by the volume of sludge.
The tank operator needs then to clean the tank in order to re-
establish its full capacity. In addition to this, national
inspection regulations require a leak test every five or 10

needs to be completely drained and cleaned. Repair work is
often performed on this occasion. The petrochemical industry
and tank terminals are increasingly choosing the option of
automated rather than manual tank cleaning.
