Tank Annular Plate Scanning (TAPS)
Advanced Inspections on Above Ground Tanks
Our TAPS (Tank Annular Plate Scanning) program is a non-intrusive, above ground tank inspection service that offers the highest probability of detection, all while eliminating the risk and time consumption of man-entry inspection methods. To do this, our ASNT NDT Level Two VT certified inspectors use Higher Order Mode Cluster (HOMC) guided waves to inspect the tank’s annular plate, the area most highly prone to localized corrosion. The unmatched sensitivity of this technology allows for a complete inspection with virtually no dead zone, to detect all cracking, pitting, and corrosion, despite typical obstructions such as the weld toe. Through superior analysis, our inspectors can expose every area that you need to call attention to, in order to prevent crisis response.
Conventional methods of tank inspection involve processes that are both hazardous and disruptive to production, such as draining the petrochemical tank to conduct a man-entry inspection. These methods, along with other non-intrusive processes with less sensitive currents, lead to a less accurate quantitative analysis, all while taking far longer to complete. The TAPS program by Waygate Technologies is designed to give the most advanced inspection analysis and combat tank failure, without having to sacrifice significant production time during testing. Our inspections don’t require any preparation and provide relatively instant data throughout the nearly two days it takes to perform. This not only provides clarity on the spot but saves producers millions each year in return. After undergoing rigorous field-testing, our technology is proven to help you protect the key-points of your tanks structure, and stick to the key dates on your schedule.

TAPS takes the guesswork out of tank evaluation, while saving producers millions by providing advanced analytics that allow for scheduled, coordinated shutdowns.
Frequently Asked Questions
Does accuracy suffer by not physically entering the tank?
Intrusive methods aren’t just dangerous, time consuming, and costly, they’re also less effective. The inspectors are often unable to properly detect the trapped water and corrosion in the annular plate region, due to the coating and uneven features of the tank’s floor. This area is crucial in the inspection process as it is the root of corrosion, which can then spread to the tank’s shell, bottom plates, and ring wall.
How far into the tank can this technology inspect?
The TAPS technology has the power to equally detect both top and bottom side flaws within 6-12 inches of the tank’s interior, even through coating and the weld toe.
How small of a chime can TAPS work with?
The size of the chime does often create limitations for conventional non-intrusive inspection systems. The strength of HOMC guided waves allow the system to work on chimes as small as 25 millimeters.
