To avoid catastrophic failures and other product-loss incidents, operators must periodically inspect atmospheric storage tanks. Realizing the serious impact of these evaluations, API published an inspection document, API-653, to help operators fully scrutinize a storage tank`s current condition and future service life. Especially for older tanks, problems can occur when vital design information, particularly weld-joint efficiency data is missing. The case history shows how to inspect and evaluate an older storage tank when corrosion is found on the lower shell concourse and critical design information is lost. This example is a step-by-step evaluation of the corrosion`s impact and extent. More important, the example identifies some pitfalls when using default assumptions for corrosion. Because storage capacity is critical, operating facilities must use all resources to their full capabilities. Operating tanks with compromised fill heights can incur losses. Use these guidelines to confirm that the tank-shell thickness satisfies API-653 requirements.
