Brominator system (figure 4, item 4). The brominator introduces bromine into the potable water tanks.

Ballast manifold (figure 4, item 5). This duplex manifold provides centralized control of the fluid level within the

Reverse Osmosis Water Purification Units (ROWPU) (figure 4, item 6). Two ROWPUs convert raw water to fresh water at

a rate of 33 to 99 gal/hr (125.6 to 250 L/hr). ROWPU 1 converts raw water to fresh water at a rate of 66 gal/hr (249.8 L/hr).

ROWPU 2 converts raw water to fresh water at a rate of 33 gal/hr (125.6 L/hr).

Access hatch for shaft alleys (figure 4, item 7). The access hatch is a hinged deck plate that provides access to the shaft

alleys.

440V power panel No. 5 (figure 4, item 8). This panel provides 440 volts power distribution for AMS 2 equipment.

Scuttle (escape hatch) and ladder (figure 4, item 9). The scuttle and ladder provide an emergency escape from

AMS 2.

10. Hydraulic sliding watertight door (figure 4, item 10). This door is a hydraulically powered sliding watertight door used

to prevent flooding from one compartment to another.

11. Two 600 lb (223.9 kg) FM-200 cylinders (figure 4, item 11). These FM-200 cylinders store the FM-200 extinguishing

agent used in the engine room and AMS 1 overhead fire suppression system.

12. Watertight door hydraulic hand pump (figure 4, item 12). This hand pump is used to open and close the engine room

sliding watertight door.

13. Potable water hydropneumatic tank (figure 4, item 13). The potable water hydropneumatic tank provides water pres-

sure to the potable water system.

14. FM-200 delay bypass cylinder (figure 4, item 14). When CLOSED, the FM-200 bypass cylinder provides a 60-second

delay before the FM-200 extinguishing agent is released. When OPEN, the FM-200 bypass cylinder redirects CO2

pressure to activate the FM-200 system immediately.

15. CO2 cylinder (figure 4, item 15). CO2 cylinders store the CO2 gas that actuates the FM-200 system.

16. Pressure switch PS-1 (figure 4, item 16). Pressure switch PS-1 shuts down the ventilation fans, SSDG's, bow thruster

engine and bow-driven engine, and activates the FM-200 amber strobes in the engine room, AMS 1 and AMS 2. The

FM-200 alarm bell on the exterior bulkhead of the engine room vestibule sounds when the FM-200 fire suppressant

system is activated.

17. Pressure switch PS-1A (figure 4, item 17). Pressure switch PS-1A activates the FM-200 electric horns in AMS 1 and the

engine room when the FM-200 fire suppressant system is activated.

18. Gyro compass repeater (figure 4, item 18). The gyro compass repeater aids steering operations during steering emer-

gencies by displaying the vessel's heading at the emergency steering station. The gyro compass repeater is fed from the

vessel's gyro compass located in the pilothouse.

19. Steering gear emergency hand pump (figure 4, item 19). This hand pump provides hydraulic pressure and directional

control to the steering gear in an emergency.

20. Rudder angle indicator (figure 4, item 20). The rudder angle indicator displays the position angle of the rudder.

21. Steering hydraulic power pack (figure 4, item 21). These two power packs, each with a motor and an onboard hydraulic

pump, provide hydraulic pressure to the steering gear.

22. Steering hydraulic power pack motor controllers (figure 4, item 22). These motor controllers provide electrical protec-

tion and control to the steering power pack electric motors.
