TANKPAC™ is not an inspection method, but a ‘sorting’ system which can separate ‘good’ tanks from ‘bad’ and thus direct maintenance to where it is most needed. Highly sensitive acoustic sensors are attached to the wall of the tank being monitored, following a period of conditioning during which valves are closed and heaters/agitators turned off.
Any fracture caused by corrosive products is detected, together with leaks which are active during the actual monitoring period. A percentage of this data is located by triangulation, but the most important information from a maintenance management point of view is the overall condition of the floor which is given a grading on an ‘A’ to ‘E’ scale.
