Fi Fi Mains
White System
: This system has a lower output as far as
volume goes
. This
main
supplies 3x
Eductor/Hydrants
(500 gpm
).
All hydrants are located on the main deck. Two are at the aft Bulwarks,
P&S
and the other is just forward of the superstructure on port side. It also supplies the 1 inch hose reel located at the aft of the superstructure mounted overhead at the boat deck level. The White system is supplied by the #
3 Engine & # 7 Pump
discharging 2000 gpm@250 psi
. It
is likely this system will be the most used on the boat.Slide2

White system Pump is rated at 2000 gpm 250 psi. This will be the workhorse system. Most hand lines, (foam capable) dewatering of vessels and washdown/containment will derive from this system. Located aft and Starboard in the ER.

The White system (2000) gpm intake valve assembly is located just forward of # 7 Engine and Pump. Notice that the actuator sets right at the floor plate level.

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!Slide10

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.Slide11

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.Slide12
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.

The controls are 24v activated from the FFS panels. The discharge valves are Electric Motor driven. The intake valves are Electric/Air. Air being the driver.

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