Acoustic Emission technology has for a number of years been used to monitor the active corrosion condition of Above Ground Storage Tanks floors.
This technique provides a non-intrusive method of determining the active corrosion condition of tank floors without the need to open, clean and inspect. Costs involved in cleaning and inspecting a tank floor can be very high, and if the floor after inspection proves to be in a good condition, then the time and cost could have been better used elsewhere.
