FOR USS

DATE:

REF: (A) MIP 5210/016-62 FIREMAIN AND FLUSHING (SEA WATER) SYSTEM 24M-2

A. INSPECT FIREMAIN PRESSURE CONTROL VALVE (PCV):
1. Is fire main pressure gauge STBD (FM-GA-51) installed and calibrated in DCRS 2 ? / Ref. A
2. Is fire main pressure gauge STBD (FM-GA-52) installed and calibrated in DCRS 5 ? / Ref. A
3. Can fire main pressure be monitored from the TAC-4 console located in DCRS 5 ? / Ref. A
4. Is the CORD flow gauge FM-GA-61 installed and calibrated? / Ref. A
B. TEST FIREMAIN PRESSURE CONTROL VALVE (PCV):
1. Induce unloaded fire main condition, loads up to 200 GPM. Observe PCV stem indicator (if installed), CORD flow, and STBD fire main pressure are satisfactory.
Refer to Table 1 below. Refer to Table 2 if no valve indicator is installed. / Ref. A
2. Induce loaded fire main condition, loads approximately 1000 GPM. Observe PCV stem (if installed), CORD flow, and STBD fire main pressure are satisfactory.
Refer to Table 1 below. Refer to Table 2 if no valve indicator is installed. / Ref. A
