2.0 - Notes
2.1 - General Notes:
1) This procedure is intended to demonstrate critical failsafe operation of the Machinery Centralized Control System.
2) The audible and visual alarms referenced in this procedure occur simultaneously at the EOS, SCC Interface Station, Chief Engineer’s Office, Assistant Engineer’s Stateroom and the Quarterdeck Operator Station (if equipped).
3) Visual alarms are displayed simultaneously at all operator stations.
4) Visual alarms on the operator stations are represented by graphic objects on the screen and may have one of three states:
a. Not in Alarm - No alarm exists; the graphic object is typically green but may display other colors except red & yellow.
b. Active Alarm - An alarm is active and has not been acknowledged indicated by blinking yellow or red.
c. Acknowledged Alarm - An alarm is active and has been acknowledged by the operator indicated by solid yellow or red.
5) Visual alarms are acknowledged at any of the Operator Stations by pressing the blinking graphic object on the touch screen.
6) Visual alarms are nearly instantaneous (within 2 seconds). All audible alarms have a 15 second delay except for those listed below. If the visual alarm is acknowledged during the 15 second delay then no audible alarm is generated.
a. Main Engine Crankcase Pressure - 1 Second Delay
b. Main Engine Over-Speed - 0 Second Delay
c. CO
Activated - 0 Second Delay
7) Audible alarms are silenced at the Operator Stations by pressing the Alarm Acknowledge pushbutton. The remote stations silence the audible at the respective station.
Silencing the alarm at the EOS silences all audible alarms. Silencing audible alarms does not affect visual alarms.
8) The Chief Engineer’s Operator Stations may be equipped with a duty alarm selector which inhibits non-vital alarms to either the Chief Engineer’s Operator Station or the
Engineer’s Stateroom Operator Station but not both. Since this test procedure tests exclusively vital system alarms the duty selector switch will have no affect on the results.
The Duty Alarm Selector Switch may not be installed on all ships.
9) Engine shutdowns occur 15 seconds after the audible alarm with the following exceptions
a. Crankcase Pressure 1 seconds
b. Over-speed - 0 Seconds
c. Lube Oil Pressure - 5 Seconds
d. CO
Activated - 1 Second
2.2 - Main Engine Shutdown Override Function:
1) The Vessels are fitted with maintained or momentary Main Engine Override switches. Momentary switches serve to inhibit engine shutdown only while continually depressed. Maintained switches operate as listed below:
a) The EOS and Ship Control Consoles are equipped with a maintained Main Engine Override selector switch. When engaged the Main Engine Override Switch will prevent the shutdowns listed below from automatically shutting down the engine. In addition, when the override is engaged an audible and visual alarm occurs and all operator stations display the text “MAIN ENGINE SHUTDOWN OVERRIDE ENGAGED” on both of the Main Engine Pages and OVERRIDE ENGAGED on the
Mimic page.
b) Table 2.1 lists shutdowns affected by the Main Engine Override Function.

4.0 - Main Engine Tests
4.1 - Introduction
The Engineer’s Operating Station utilizes a hybrid of pneumatic and PLC technologies to monitor and control the two General Motors EMD 20-645-E7B marine engines and associated machinery. It is the primary control station for the main engines and associated machinery, although a duplicate set of controls exists on the Ship Control Console.
Pneumatic controls located at the EOS and SCC control which station will have control. Each station has duplicate pneumatic controls for Engine speed, propeller pitch, etc.
A “Hot Standby” PLC controller housed within the Engine Control Console constantly monitors the main engines and associated machinery for conditions which are potentially harmful to the equipment or dangerous to personnel and reacts by initiating an alarm to warn the ship’s engineers or automatically shutting down the engine. This is accomplished through the use of sensors mounted directly on the engines and associated machinery hardwired to the Engine Control Console.
The following tests will verify the operation of these critical systems.
4.2 - Main Engine Analog Sensors Tests:
The following tests are intended to verify both proper operation and accuracy of critical system Temperature and pressure sensors. Each of the sensors will be compared to an accurate source at two points within their respective operating range. Performing these tests may generate audible and visual alarms which should be disregarded since the alarm and shutdown functionality are tested in section 4.3. To insure these tests are performed safely and effectively, the main engines should be stopped. Test each of the sensors listed below using either the RTD Sensor Test Procedure (Section10.2) or the Pressure Sensor Test Procedure (Section 10.3) for guidance. Record the test results in Test Table 4.2.

4.4 - Main Engine Safety and Shutdown Tests:
The Engineer’s Operating Station provides the Authorized Engineer with the ability to change each of the critical alarm and shutdown set points. These adjustable set points can be accessed through a semi-hidden button on the Port and Starboard Main Engine pages of the 15” touch screen displays located in the Controller Cabinet of the Engineer’s
Operating Station. Since the operation and accuracy of the analog inputs have been tested and verified, and the basic operation of the main engines have also been tested and verified, the safety and shutdown functions can now be tested by adjusting each of the set points to a value which will generate the required alarm or shutdown condition. These tests will be performed with the engine running. See notes below. Each of the warning alarms, critical alarms, and shutdowns has a unique time delay. A detailed description of the delays and their operation is located at the beginning of this procedure. The unique time delay for each of the alarms and shutdowns are listed on Test Table 4.4.
The crankcase pressure switch is mounted directly to the main engine. The associated shutdown will be tested using the discrete (Pressure Switch) procedure to produce a pressure that will activate the shutdown.
**NOTE 1** Lube oil pressure and fuel oil pressure warning alarms, critical alarms, and shutdowns are disabled when the engine is stopped.
**NOTE 2** Red Gear lube oil pressure warning alarms, critical alarms, and shutdowns are disabled when shaft speed is below 10 RPM or if the clutch is disengaged. Red gear lube oil temperature critical alarms and shutdowns are disabled when the clutch is disengaged. To test these functions the engine must be running and the clutch engaged for 10 seconds.
Test each of the warning alarms, critical alarms, and shutdowns listed on Table 4.4.
Test the crankcase pressure shutdown using the Discrete Input Sensor Test Procedure (Section 10.1) for guidance.

6.0 - Ship Service Diesel Generators
The T-ATF class ships were repowered with three Caterpillar C18 SSDGs in 2012. Each SSDG is equipped with a Marine Classification Society (MCS) controller which monitors the diesel engines for conditions which are potentially harmful to equipment or dangerous to personnel and reacts by initiating an alarm or automatically shutting down the SSDG.
This is accomplished through sensors provided with the generators and mounted directly on the engine. The MCS controllers are installed on or near each of the SSDGs. The
Machinery Centralized Control System (MCCS) monitors the SSDGs via the MCS and broadcasts equipment status, alarms and shutdowns to the EOS, SCC and remote operator stations. Additionally, the MCCS starts the standby SSDG when a dead bus occurs. The following tests will verify the operation of these critical systems.
Recommended shutdown settings are listed in Tables 11.2 – 11.6.
NOTE:
Prior to commencing SSDG test, verify the MCS is fully functional, all required maintenance has been accomplished and no alarms are outstanding.

The T-ATF class of ships utilizes a variety of discrete input sensors; most commonly: pressure switches, level switches, temperature switches, etc. Although the sensors are typically a rudimentary device, access to the sensors can often be difficult and time consuming. In many cases removal of the sensor requires complete disassembly of the sensor and (or) the associated machinery. It is for this reason, and because of the variety of sensors installed, this procedure details several methods for testing these devices.
Method #1: (Primary Method)
Test each discrete input by operating the associated machinery in a manner that will force the discrete sensor into an alarm state.
If the Method #1 test is unreasonable due to the levels of difficulty to perform the test, endangerment of personnel, or damage to machinery, test the device by using the applicable procedure below:
Method #2:
Level Sensors (Flooding, High Level, Low Level, etc.):
Visually inspect the float for faults. Operate the level sensor float device mechanically to create an alarm condition.
Temperature Switches:
Remove the switch. Disconnect the electrical connection if necessary to remove it. Reconnect the electrical connection prior to testing. Place the switch in a thermowell, and set to a sufficient temperature to create an alarm condition.
Pressure Switches:
Remove the switch if necessary. Disconnect the electrical connection if necessary to remove it. Reconnect the electrical connection prior to testing. Connect the input of the pressure switch to a pressure tester. Adjust the pressure tester to produce enough pressure to cause the switch to operate.
Method #3:
Mechanically operate the sensor. (Lift the float; press the micro switch with a screwdriver, etc.)
Method #4:
Short or open the electrical circuit connection at the sensor.
