Bell Logger |
In Main 1 behind the console. It records all the ship's speed changes no matter how big or small |
|
|
Enclosed Operating Station Console |
This is the console for all the readouts for the space equipment. It also allows you to start and stop main engines and monitor their pressures and operating limits |
|
|
Local Operating Station |
Has control of all the controls and ran from the main space (Throttle, CPP, MRG, clutch, etc) 3 settings |
|
|
Discuss the priority of combined throttle control from the engine room to the bridge |
The bridge will take control of the shaft underway because they know what is going on at all times. EOS will take control of the shaft in the case of an emergency and have complete control of the shaft and engines during emergency situations. |
|
|
State the purpose of the Controllable Pitch Propeller system |
Allows the propellers to obtain maximum thrust at any given rpm. Also allows ships with diesel or Gas Turbine plants to revers without having a reversing gear. Propellers reverse the thrust by rotating blades to push water forward or backward allowing the engines to maintain one direction of the shaft. |
|
|
Hydraulic Oil Power Unit |
Located lower level aft starboard side in MMR2 and lower level portside MMR1. It delivers pressure-regulated oil to power oil piping and to control oil piping. Purpose of the Hydraulic Oil Power unit is to supply both HP hydraulic oil for propeller blade actuation and control oil for propeller pitch control |
|
|
Gear/Attached Pump |
gear driven pump attached to the MRG. The pump draws oil from the sump tank through a foot valve and a suction strainer. The foot valve allows oil flow in one direction only, thus preventing the back flow of oil from the pump to the tank when the pump is shut down. |
|
|
Electric/Standby Pump |
A separate pump used as a backup to the attached pump |
|
|
Oil Distribution Box |
Has two main purposes: (1) It provides the actuation and control of the regulating valve rod and (2) it directs HP hydraulic oil to and from the propeller shaft flow passages. It also provides the mounting for the manifold block assembly, local pitch indicator, linear feedback potentiometer, and shaped readout potentiometer system. |
|
|
CPP Head Tank |
Connects to the return oil chamber through a flange located on the top aft section of the Oil Distribution Box. The purpose of the head tank is to maintain a static head pressure on the oil in the propeller hub when the hydraulic system is shut down. This prevents seawater from leaking past the blade seals into the hydraulic system |
|
|
Emergency Pitch Positioner System |
Can mechanically position and lock the propellers if the system loses hydraulic power. Emergency pitch connections are used when control oil or HP oil are not available from the Hydraulic Oil Power Unit |
|
|
Propeller Assembly |
Consists of the Propeller Hub and Propeller Blades. |
|
|
Propeller Hub |
Provides the mounting for the propeller blades and contains the hydraulic servomotor mechanism for blade pitch control. It also transforms propulsion shaft rotational torque into axial thrust for ships propulsion. The hub body is normally secured to the tail shaft flange by 15 bolts and 5 dowel pins. The rotational torque of the propulsion shaft is transmitted to the hub by the 5 dowel pins |
|
|
Propeller blades |
Bolted to the propeller hub. The propeller blades are what provide thrust to push the ship through water. Normal system propellers have 5 nickle bronze alloy blades, 17 feet in diameter, which develop 40,000 shaft horsepower at 168 rpm. Each blade is attached to a crankpin ring with 8 bolts. A mechanical air channel runs along the blade leading edge from the root to the blade tip. This channel provides the flow path for prairie air which discharges through small orifices located along the leading edge. Prairie air is delivered to the blades through the prairie air tube that runs through the regulating valve rod from the OD box to the hub cone. A check valve in the hub cone prevents seawater from entering the prairie air system when air is not flowing. |

|
State the type of distilling plant used onboard and its maximum daily distilling capacity |
Two 3-stage flash type distilling plants. Daily capacity is 30,000 gallons |
|
|
State the location of basic operation of the ships distilling plants |
#1 in MMR1 #2 in MMR2. Water is drawn from the sea through the feed pump. It then goes through the duplex strainers, through the distillate coolers (which heat it up) then through the 3rd, 2nd, and 1st stage condensers. Then it goes through the 1st stage spray cap which vaporizes the water. It then hits the mister pads which collect s the water as distilled water. Any water that is not vaporized at the spray cap is brine. The brine is sent back to the ocean via the brine pumps. Distilled water can go to three different places (1) reserve feed, (2) LCAC washdown, or (3) potable water tanks |
|
|
State the shops maximum storage capacity for potable water |

|
|
Potable water tanks |
Four tanks total - two port and two starboard, both forward of aux 1 |
|
|
Brominators |
Three total, all located in Aux 1. two are proportioning. Proportioning are located between the evaps and potable water tanks. They are used as the distilled water comes from the evaps to the tanks. One is a recirculating brominator. It is used if the brominating level is below .2 and it takes suction from the potable water tank and recirculates it through the brominator and right back into the tank. |
|
|
Potable Water Risers |
Located port side between the boat deck and the RAS station and starboard side on the RAS station |
|
|

Gland inflates and friction blocks come into contact with the clutch drum, locking the drive shaft with the engine |
|
|
Shaft brake |
Propeller shaft brake assembly is mounted on each starboard first reduction quill shaft. Each assembly has 3 disk caliper brakes. They are controlled by a single solenoid valve in the propeller shaft brake panel. This solenoid valve is controlled electrically at the PCC, LOP, or SCC. The valve also may be actuated manually at the propeller shaft brake panel |
