● 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. Red System pumping cap. 7500 gpm.

Fi Fi Nozzles

Deflector Style Fog-Jet Style

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.

● 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 the starboard, forward main deck discharge manifold. Green System pumping capacity 7500 gpm.

● 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 ● Red and Green systems. Driven off the rear of the Cat-3512 drive engines

Starboard System (Green) is identical to the Port side. The difference is the control/monitor/maintenance side of the pump unit is facing outside toward the hull. A little tougher to get too.

outboard of the pump intake under the floor plates. This sets in the ER just forward of the #7pump.

Fire Fighting SystemsDischarge 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!

Fire Fighting SystemsDischarge 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.

● Clapper Valve bypass (drain)

● Clapper Valve● Isolation Valves● Bypass Loop● (RC) Discharge

Valve● 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.

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 theIsolation valve we mentioned earlier.
