Red System
: Port Side Fire Main supplies two Monitors.
M7
(6000) gpm on centerline
on the
fwd
Wheelhouse top.
M8 the smaller monitor (1500) gpm is on the boat deck level, just forward of the Wheelhouse. Both of these Monitors are Fog-Jet style
nozzles(RC).
Only the
Blue
system
has a Fire Main Isolation valve.
Lastly, the
Red System
supplies the Port discharge Manifold on the forward main deck.

The operator has to always be aware of the nozzles pointed direction when opening up the system. In the Wheelhouse you can not see the house top monitors. Slide3

Green System
: Starboard side Fire Main also supplies two
Monitors:
M9
(6000) gpm located
on
Aft Wheelhouse top, centerline
and M10 (1500) gpm mounted on the starboard side of the forward boat deck just in front of the CIC. Both these monitors are Fog-Jet style nozzles (RC). This fire main also supplies

2-SFP 250x350XP FFS Fire Fighting Pumps 7500 gpm @ 180 psi Pumps 1 and 2.
Single stage centrifugal pump
PTO driven via a flexible coupling
Unit is equipped with a multi-disc clutch that is hydraulically engaged. The hydraulic pump is internal. The pump also cools and lubricates the unit.
Cooling is accomplished internally while pumping
Pressure and Temperature gages each with switches (alarms)
Oil filter with a clogging indicator
Remotely operated (24v)
Can be manually operated at the unit in emergency conditions
Clutch housing contains 10.5 gallons of oil. NEVER use hydraulic oil

The difference is the control/

Discharge Piping
The Discharge piping consists of a series of valves, check valves (clappers) and bypasses. Also system
pressure sensors
. As previously
mentioned,
the
Blue System has an Isolation valve to separate
the system into two parts if wanted.We are not going to trace all the systems out with a pictorial highway. To much to show. You will see it soon enough. But since these systems are all similar,
a of couple of pictures will suffice. We will look at the bypasses, clappers and fire main overboard discharges.It is important to remember that there are
NO relief valves in these Fire Fighting Systems. The occurrence of a Water Hammer has to be constantly on the mind of the operator while pumping. Thousands of gallons (weight) in motion can not stop quicky without damaging something! Take your time!Slide19

Discharge Piping
Clapper Valve
All discharge systems are identical in regards to the valving, clapper- valves and bypasses. Remember the discharge valves are remotely controlled from the wheelhouse FFS panels.Slide20

Sensors/Gages
The
idea
of the bypass loop is to be able to fill the system very
slowly to minimize water hammer. In reality
we will leave the isolation valve open and fill the system at
idle,
watching for a lazy discharge out the
monitors.
Possibly at times using the overboard
discharges.Slide21
Fire Fighting Systems
Fire Main Overboards
The overboard systems are remotely controlled from the FFS panels. The operator can use the Overboards to divert pressure or drain a system. The water flow is directed downward at the through hull for obvious reasons. Visualize the out flow.

Notice there are two Blue gages. This is because the Blue system can be separated by the
Isolation valve we mentioned earlier.
