AP1653 TANK"/N SERV/CE"/NSPECT/ON APPcus RTD O <br /> CUSTOMER: AMERICAN BIODIESEL,INC INSP DATE(S): 10/25/2017 <br /> LOCATION: STOCKTON, CA CONTACT: MIKE PARISSI <br /> INSP TYPE: API 653 EXTERNAL AND UT INSPECTOR(S): RONNIE HARLESTON <br /> EQUIPMENT TYPE/DESCRIPTION: 25,000 GALLON STORAGE TANK <br /> SERIAL/ID/ASSET#: T-118 <br /> INSPECTION COMMENTS/ CONCERNS / RECOMMENDATIONS: <br /> Ultrasonic A-Scan Thickness Survey: <br /> New TML locations were established and new base line reading was taken. See field drawing for new TML <br /> location. Ultrasonic A-Scan thickness measurements were performed on the shell, roof, and cone. All readings <br /> have been entered into Ultra Pipe and after review of the data next inspection date will be 10/25/2022. The <br /> predicted retirement date of the tank is 01/06/2029 based on a 2 mil a year default corrosion rate. There are <br /> 0 caution TML locations per the current thickness survey completed on 10/25/2017. <br /> API 653 External Inspection. <br /> External visual inspection found this cone bottom tank to be in fair condition. This tank is fully foam insulated <br /> and the insulation is in poor condition. There are areas of the insulation bulging and cracked open. This tank <br /> is mounted on 4 vertical H-beams leg support system. The support legs are painted and found to be in good <br /> condition with no significant issues found. The foundation is a concrete slab above grade level and is intact, <br /> with no indications of settling noted. All anchor bolts are present, installed in the concrete foundation and are <br /> in good condition. The nozzles and flanges are free of significant corrosion or leakage. All bolting is intact, <br /> with no significant thread or fastener degradation found. Shell surfaces were inspected through the <br /> inspection ports and where the insulation has failed and found light surface rusting present with no significant <br /> corrosion noted. The installed static ground is intact and securely attached <br /> Recommendations: <br /> Re-move all damaged insulation and check for CUI (corrosion under insulation) or any other damages to the <br /> tank. Sandblast those areas and apply a new paint coat before re-insulating. <br /> The next external visual inspection will be time based at 5 years. <br /> API 653 Internal Inspection: <br /> Internal inspection was not scheduled at the time of this inspection. Internal inspection is recommended at <br /> the next planned shutdown. <br /> Inspectors Name and API# Inspectors Signature Date <br /> James Reese 44021 10/25/2017 <br /> f <br /> 9 <br />
