5.4.3 Pump selection other than that listed above may only be approved by COTR or Chief Engineer.
5.5 REMOVAL OF OLD MSW PUMPS
5.5.1 With assistance of ship’s crew #1, #2 and #3 MSW Pumps shall be electrically and physically tagged out. During work all suction and discharge piping shall be blanked prior to installing new pumps.
5.5.2 Existing pumps shall be removed from system, preserved, palletized and delivered to the MARAD warehouse in Alameda, CA.
5.6 SUCTION AND DISCHARGE VALVE REPAIR AND RENEWAL
5.6.1 The three (3) 10 inch Discharge Stop Check Valves shall be rebuilt with new seats and discs or renewed.
5.6.1.1 Current valves are Bronze 150 angle stop checks manufactured by Pima.
5.7 NEW PUMP INSTALLATION
5.7.1 The intent is for the new pump installation to “target” the new pump discharge flanges to the existing 10 inch discharge elbows. Refer to sketch for suggested piping arrangement.
5.7.2 Contractor shall rig new pumps to site of installation.
5.7.3 New pumps shall be supported by plate “Saddles” bolted to pump suction and discharge flanges and bolted to existing 6” x 6” angle iron support structure which crosses fore and aft at pump flanges. Saddles should be fashioned to match those fabricated for the #1 and #2 Auxiliary Seawater Pump installations. Refer to ASW Installation Drawings 1040-S11-13-1 and 140-S11-13-2. NOTE: Dimensions from these drawings will have to be scaled up to reflect larger Main Seawater Pumps flange sizes.
5.7.4 Pump suction piping shall require the fashioning of new 12” to 8” spool piece transitions. These transitions shall be constructed of 70 - 30 copper nickel. Existing flanges may be reused to fashion transitions. Refer to sketch for suggested piping arrangement.
