5 3.0 INSPECTION RESULTS, 3.1 Foundation: 3.2 Shell: The vessel rests in two concrete foundation support saddles with rubber liners in between the tank and saddles The concrete saddles are in satisfactory condition The shell is carbon steel with 8 to 15 mil epoxy external coating and is un-insulated The external surface profiles of the shell appear to be smooth and clean and in satisfactory mechanical condition. The shell coating is in satisfactory condition The shell nozzle penetration welds appeared to be in satisfactory condition. 3.3 Head(s): IN-SERVICE The following results are the summarization of a field checklist that was utilized during the inspection of vessel The West and East heads are carbon steel with 8 to 15 mil epoxy external coating and are un-insulated. The West and East heads have a hemispherical design The external surface profiles of the West and East heads appear to be smooth and clean and in satisfactory mechanical condition. The coating on both heads is in satisfactory condition The nozzle penetration welds through the both heads appeared to be in satisfactory condition. 3.4 Appurtenances: The shell and head nozzles appear to be clean and in satisfactory mechanical condition. There are areas scattered throughout the relief valve vent piping with coating failure and surface oxidation The four (4) pressure relief valves do not have data tags attached specifying certification date or set pressure The flange on shell nozzle K (24" Manway) has visible corrosion in the flange gap The ASME dataplate is attached and in an easily accessed location. The plate is faded and barley readable. A data plate is affixed to the vessel The pressure and temperature gauges do not have calibration tags. Report No.: Page 5

7 5.0 ULTRASONIC THICKNESS (UT) MEASUREMENTS 5.1 Results Summary: UT measurement of accessible vessel components (shell and heads) found no significant material loss due to internal corrosion of the components. All of the vessel component thicknesses were nominal and acceptable for ASME calculations for minimum required thicknesses for internal pressure Calculations of all evaluated components resulted in greater than 20 years remaining life. 5.2 Recommendations: Next UT inspection of the vessel may be scheduled in 10 years in accordance with maximum allowable intervals recommended by API-510.
