Innovative techniques for tank storage inspection

A unique NDT method has been developed for the inspection of welds in storage tanks that not only increases operational reliability but also reduces inspection costs.
TWI – an independent research and technology organisation – devised the new inspection technique to measure the inner fillet from outside the tank, thus removing the need to drain the asset.
The company’s asset integrity management experts have been involved in storage tank inspection for many years – initially addressing steel storage tanks in refineries – and more latterly, looking at polymer-based storage tanks in the petro-chemical industry. Non-destructive testing techniques including magnetic particle, ultrasonic and radiographic testing are used in the inspection of storage tanks, as increasingly are condition and structural health monitoring methods such as acoustic emission testing.
Steel storage tanks are known to be susceptible to internal corrosion due to water settling at the bottom, particularly around the inner fillet welds between the vertical wall and the base plate which are vital structural elements. Historically, inspection of large storage tanks has been lengthy because it requires draining the tank, disposing of any contaminated materials and extensive cleaning.
