Standard Guide for Hydraulic Integrity of New, Repaired, or Reconstructed Aboveground Storage Tank Bottoms for Petroleum Service

Importancia y uso:

5.1 Inspection, repair, and construction of ASTs in petroleum service should follow at a minimum the requirements of API 650 and API 653. These standards describe methods for testing the weld quality and structural and hydraulic integrity of new or repaired ASTs. With increasing emphasis on protecting the environment and with environmental issues related to the storing of petroleum materials in ASTs, owners and operators of such tanks may want or need a guide devoted to existing and enhanced methods for evaluating the hydraulic integrity of new or repaired tank bottoms.

5.2 The consequences of a tank bottom failure include the economic loss of product, cost of repair or replacing the tank bottom, and exposure to the cost of environmental remediation and potential damage or harm to adjacent lands that may give rise to adverse public relations or regulatory action. In addition, releases of petroleum products introduce potential fire or explosive conditions.

5.3 Owners and operators of ASTs or their agents can use this guide to help choose methods of evaluating the hydraulic integrity of their repaired or new tank bottoms. Selection of the methods should be based on regulatory and economic criteria that include operational and cost/benefit considerations.

5.4 This guide is intended for use by an individual experienced in repair and construction of ASTs in petroleum service.

5.5 This guide is intended for use when repairing or building ASTs. This guide does not address suitability for use or imply useful life of an AST bottom.

5.6 This guide is intended to be used in conjunction with and as a supplement to standards provided for hydraulic integrity in API 650 and API 653.

5.7 Procedures or methods included here may be supported by a previously completed and documented performance evaluation(s) that may lend itself as valuable results validation.
