Chapter 7: Inspection, Evaluation,and Testing_ <br /> • Section 10 addresses recordkeeping and inspection reports. <br /> • Appendix A describes selected methods for non-destructive examination of tanks, including <br /> ultrasonic thickness measurement, ultrasonic corrosion testing, ultrasonic shear wave testing, <br /> magnetic flux testing and robotic inspection. <br /> • Appendix B contains similar service evaluation tables for corrosion rates. <br /> • Appendix C provides a selected bibliography. <br /> 7.7.5 API Recommended Practice 12111 - Recommended Practice for Setting, Maintenance, <br /> Inspection, Operation,and Repair of Tanks in Oil Production Service <br /> API Recommended Practice 12111—Recommended Practice for Setting, Maintenance, Inspection, <br /> Operation, and Repair of Tanks in Production Service (API RP 12R1)159 provides guidance on new tank <br /> installations and maintenance of existing oil production tanks.These tanks are often referred to as "upstream" <br /> or"extraction and production (E&P)tanks." <br /> This recommended practice is primarily intended for tanks fabricated to API Specifications 1213, D, F, and <br /> P that are employed in on-land production service.160 The basic principles in this recommended practice can also <br /> be applied to other atmospheric tanks in similar oil and gas production,treating, and processing services; <br /> however,they are not applicable to refineries, marketing bulk stations, petrochemical plants, or pipeline storage <br /> facilities operated by carriers. According to the recommended practice,tanks that are fabricated to API <br /> Standards 12C or 650 should be maintained in accordance with API 653, summarized above. <br /> The recommended practice is organized as follows: <br /> • Sections 1, 2, and 3 describe the scope of the standard,the 19 standards it references, and the <br /> relevant definitions, respectively.The remaining four main sections describe the recommended <br /> practices. <br /> • Section 4 provides recommended practices for setting of new or relocated tanks and connecting <br /> tanks. <br /> • Section 5 recommends practices for safe operation and spill prevention for tanks."' <br /> 159 API Recommended Practice 12R1,"Recommended Practice for Setting,Maintenance,Inspection,Operation,and Repair of <br /> Tanks in Production Service,"5th edition.American Petroleum Institute.August 1997,Reaffirmed April 2008. <br /> 160 API Specifications 126,D,F,and P correspond to bolted tanks for storage of production liquids,field welded tanks for storage of <br /> production liquids,shop welded tanks for storage of production liquids,and specification for fiberglass reinforced plastic tanks, <br /> respectively. <br /> 161 The scope of API RP 12R1 states that"the spill prevention and examination/inspection provisions of this recommended practice <br /> should be a companion to the spill prevention control and countermeasures(SPCC)to prevent environmental damage." <br /> SPCC GUIDANCE FOR REGIONAL INSPECTORS 7-68 <br /> December 16, 2013 <br />
