3-3.4 Supplying seawater from cooling pump to air conditioning and chlorination units
NOTE
See Figures 1-5 thru 1-1 for seawater valve locations.
a.
Perform before operation checks in paragraph 4-3.
b.
Close seawater valve SW48 to turn off seawater from nonoperating seawater pumps in void 2 starboard.
c.
Open seawater valves SW3 and SW27 in void 2 port to supply seawater to cooling pump.
d.
Open seawater valves SW35 and SW36 in void 2 port to monitor pressure differences between input and output
of seawater strainer 3 supplying seawater to cooling pump.
e.
To supply seawater to chlorination unit and air conditioner, open seawater valves SW28 (Barges 2 and 3 only)
and SW47.
f.
To supply seawater to air conditioner only, open seawater valve SW28 (Barges 2 and 3 only) and close SW47.
g.
To supply seawater to chlorination unit only, open seawater valve SW47 and close SW28 (Barges 2 and 3 only).
h.
Set seawater pressure regulator to supply 10 psi of seawater to chlorination unit.
i.
Start cooling pump by pressing START button on cooling pump motor controller on center bulkhead in void 2 port.
j.
While operating, perform during operation checks.
NOTE
Ballasting may be necessary to establish 9 inch bow high trim in preparation for
towing or to establish barge on an even keel when deployed for processing water.
3-3.5 Filling ballast tank (to correct a bow high condition)
NOTE
Filling ballast tank requires only one seawater pump. The other seawater pump
may be used to supply seawater to one ROWPU unit. See Figures 1-3 and 1-4 for
seawater valve locations.
3-3.5.1 Filling ballast tank from forward seachest
a.
Perform before operation checks in paragraph 4-3.
b.
Open seawater valves SW31 thru SW34 in void 2 starboard.
c.
Close seawater valves SW4 thru SW8, SW11, SW12, SW18, and SW20 in void 2 starboard.
