It is known the high cost and the complexity of manufacturing large storage tanks manufacturing (with a diameter larger than 200 ft). Storage tanks in power and process plants, after years in operation, and due to the continuous modification of operating conditions, must be replaced or modified to comply with new design conditions and/or integrity requirements.
The main question arises: Is it necessary to completely replace such tanks due to the new conditions and requirements?
API-653 can be applied for validating and repairing these atmospheric storage tanks by means of evaluation and calculation of the tank according to the new design conditions. After this evaluation, design modifications can be defined as well as repair of damaged or non-compliance parts that result in not valid for new design conditions according to API-653 code. This approach uses to be a more affordable and convenient solution than replace or great repairs.
