Non-invasive structural health monitoring of storage tank floors
Large above ground storage tanks filled with hydrocarbon and hazardous liquids such as oil, oil-derived products, chemicals
 and process plant liquids are in widespread use in the UK, Europe and throughout the world. Tank farms are normally located in

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Large above ground storage tanks filled with hydrocarbon and hazardous liquids such as oil, oil-derived products, chemicals
and process plant liquids are in widespread use in the UK, Europe and throughout the world. Tank farms are normally located in
coastal areas close to large centres of population. Leakage from corroded storage tanks, especially from their floors, is a major
environmental and economic hazard and poses a significant threat to those living in the vicinity of tank farms, as well as to the
rest of the UK and Europe. The current, and growing, risk of tank failure together with the potential risk for fire and explosion at
nearby petrochemical plants is wholly unacceptable. This paper illustrates the work carried out in the UK Technology Strategy
Board (TSB) Tank Integrity Monitoring (TIM) project, for the structural health monitoring of large above ground bulk liquid
storage tank floors without the need to access the inside of the tank or to empty its contents, using ultrasonic guided waves
(UGW) as a non-destructive testing technique. A structural health monitoring system for acquiring ultrasonic guided wave data
over long periods of time was developed. The performance of the permanent attached transducers and the structural health
monitoring system was also investigated to demonstrate their reliability. The propagation of the guided wave signals has been
validated experimentally on a 4 m diameter tank floor, and tomography imaging has been developed for detection and location
of defects.
