11-10 Operating controls and Indicators. Operating controls and indicators are listed in Table 11-4 and shown in
Figures 11-8 thru 11-10. Information on ROWPU and ballast seawater supply valves is in Table 11-5. Location of valves
is shown in Figure 11-11. Information on air conditioning and chlorination cooling flow valves is in Table 11-5. Location of
these valves is shown in Figure 11-3. Information on generator cooling flow valves is in Table 11-5. Location of these
valves is shown in Figure 11-5.
11-11 Prestart procedures
Wipe components clean, especially gauges and control panels.
Check for leaks, paying special attention to all joints, valves, fittings, and piping. Report leaks to shift leader so
corrective action can be taken.
Check for damage especially to pressure gauges, filters, and control panels.
Check for loose or missing securements and fasteners. Tighten or replace as necessary.
Check wiring for loose connections and frayed cables. Secure as necessary. Repair or replace damaged cables.
Check if seawater strainer baskets are dean and properly installed.
Provide power to ROWPU 1 and 2 control stations by dosing (ON) switchboard circuit breakers P6 and P7.
Provide power to cooling pump controller by dosing (ON) power panel 1 circuit breaker 1 P5.
11-12 Normal and alternate operating procedures
Do not open seachest valves SW1, SW2, or SW3 unless valve SW30 is open to vent
seachest to the atmosphere.
Seawater being supplied to ROWPU's must not be contaminated with oil,
detergents, chlorine, or other foreign matter. Contaminated seawater could
damage ROWPU membranes.
Water below barge seachests must be deep enough to make sure sand and other
foreign matter are not sucked Into the system with the seawater.
Deep water Is defined as water 15 feet deep or more. Shallow water is defined as
water less than 15 feet deep.
Supplying seawater to ROWPU's is covered in paragraphs 11-12.1 and 11-12.2.
Supplying seawater to chlorination and air conditioning units is covered in paragraphs 11-12.3 and 11-12.4.
Supplying seawater for filling and draining ballast tank is covered in paragraphs 11-12.5 and 11-12.6.
Supplying seawater for cooling diesel engine generators is covered in paragraph 11-12.7.
Seachest blowdown is covered in paragraph 11-12.8.
