The inspection was in line with the American Petroleum Institute (API) 653 Standard “Tank Inspection, Repair, Alteration & Reconstruction” with a scope to establish the corrosion rates, the remaining life and verify the integrity and safe operation of the tanks.
A thorough visual inspection took place to foundation, shells, floating roof, appurtenances including all pipe networks, nozzles and valves as well as dump accessories and alarming systems.
Non-Destructive examination using MT, Thermography and UT technology including a crawler robot has been utilized to configure the minimum thickness of the shells and roof. Furthermore, a topographic survey analysis has been performed to record tanks settlement.
