Rapid inspection of damage of the annular ring and welds of Above Ground Storage Tanks

TALRUT™ TANK ANNULAR LONG RANGE ULTRASONIC TESTING

Non Intrusive Inspection (NII) technologies can be used to provide information on the status of the tank condition while in operation.

Technologies such as Acoustic Emission (TANKPAC™), Automated Ultrasonic Thickness Mapping (LSITM) and Tank Annular Long Range Ultrasonics (TALRUTTM) can yield information to support a Risk Based Inspection (RBI) approach.

TALRUTTM is an ultrasonic inspection technique developed by MISTRAS to specifically look for damage in the annular plates of metallic above ground storage tanks.

The technique utilises the properties of tuned long range ultrasonic waves to obtain information about damage to the annular plate.

Inspection results are presented in a tabular and graphical format. Defects severity grading and thickness are presented in tables along with the positional information about scans and defects. The graphical information provided shows all scanned areas and any defects that are found.

OIL & GAS

TALRUT™ highlights

Quick deployment with battery operated equipment

Along with the long range UT data the system collects thickness data on the chime adjacent to the annular plate weld

Mechanised scanner to cover the entire annular accurately and efficiently (scanning speeds of 40-50m / shift are expected)

The method uses water coupling and some surface preparation maybe required for optimum results

80% POD in industry blind trials with the lowest false call rate out of all techniques tested

More sensitive to localised damage versus gradual thinning

Inspection penetration depth is 400mm but higher depths are possible

Semi quantitative results grade floor damage in three categories or “no damage”

Any annular plate thickness can be inspected
