3. Engineering Review of Tanks & Equipment Covered by CalARP Program <br />C:\TRICH\Jobs\4515582 Leprino Tracy\Report\Leprino Tracy CalARP 040221.docx 3-2 <br />• Foundation drawings showing concrete piers, spread footings, or mat <br />foundations. <br />Such design information was very limited for the covered process. Thus, most of the <br />data used for the tank and equipment seismic evaluation was collected from the seismic <br />walkdown. Although the 1970 soils report was not reviewed, information from that report <br />was included in the 1999 CalARP seismic report and referenced in this report. <br />3.2 Seismic Walkdown Review <br />The purpose of the seismic walkdown consists of: <br />• Screening out equipment such as piping, valves, and small vessels that are <br />inherently seismically rugged. <br />• Identifying seismic vulnerabilities in tanks, equipment and piping. <br />• Identify effects of earthquake on adjacent non-covered equipment or structures <br />that may fail and impact the covered equipment. <br />• Collect information such as tank and equipment dimensions, tank and equipment <br />support, and as-installed anchorage for performing seismic capacity evaluation. <br />Seismic walkdown findings are presented in appendix B with major findings discussed <br />below. An attempt was made to group equipment by area, with the primary areas being <br />the Main Engine Room and QLC Engine Room. The equipment in process areas are <br />fed from one of these two engine rooms. Many pieces of equipment have two different <br />numbers on the P&ID drawings with the second one being used to label the equipment. <br />The previous reports used both numbers. This report uses the number marked on the <br />equipment and on the P&ID drawings for easy correlation to the photographs. <br />While the equipment in the Main Engine Room was manufactured between 1973 and <br />2002, most equipment in the QLC Engine Room was manufactured in 1987. The <br />manufacturing date was determined using information on the equipment U-1A <br />(Manufacturer Data Report for Pressure Vessels) forms (Appendix C) and observed <br />equipment placards. The year of installation was assumed to be the same as the <br />manufacturing date assuming the equipment was new when installed and not moved
