1.
Purpose
The purpose is to set forth general instructions for the operations of the CATERPILLAR
3406 Emergency Generator installed on ATLANTIS.
2.
Responsibility
It is the responsibility of the Chief Engineer to maintain guidelines for operating the
Emergency Generator. It is also the responsibility of the Chief Engineer to ensure the
Emergency Generator is fully functional and tested as per USCG requirements
3.
References
a) R/V ATLANTIS Engineering Department Standard Operating Policies and
Procedure (located in MCS)
b) USCG requirements
4.
General
The Emergency Generator is to be operated without an electrical load (unloaded) for no
less than one hour per week, and electrically loaded (with a load) for a minimum no less
than 2- hours per month as per USCG 196.15-30.
5.
Reporting
The testing and general condition of the Emergency Generator is to be recorded in the
“official” Engine Room and Bridge logbooks. In addition, an entry must be made in
SAFENET.

EMERGENCY GENERATOR OPERATING
AND TESTING PROCEDURE
Normal Operation
1. Fuel Supply and Return valves are open.
2. “Engine Mode Selector Switch” is in the “AUTO” position.
3. “Emergency Generator Mode Selector Switch” is in the “NORMAL” position.
Testing Procedures for the Emergency Generator
No-Load Running
1. Place the Emergency generator Mode Selector Switch from “Auto” to “Manual”. This will
start the generator, bring it up to speed, but will not open the bus-tie breaker or close the
generator circuit breaker.
Note: Normal opening time for the ventilation louvers is approximately 3 minutes.
2. After finishing with no-load run test, place the engine mode selector switch in the “Off”
position (This will stop the engine after about 15 seconds). Then place the Engine
Mode Selector Switch into the “Auto “ position. Note: Normal closing time for ventilation
louvers is around 5 seconds.
Simulation of Load Loss from Main 480-Volt Switchboard.
1. Simulation “A”:
a. Place Emergency generator mode selector switch in the “TEST” position.
b. This will trip the emergency generator switchboard bus-tie breaker. When the
engine starts and comes up to speed, the generator breaker closes and feeds
the Emergency bus and switchboard.
2. Simulation “B”:
a. At the 480 Volt Switchboard, trip breaker # P409 (Emergency Switchboard) to
simulate loss of normal power to the emergency switchboard.

b. This will cause an under voltage trip, which in turn will cause the emergency
switchboard bus-tie breaker to open. The generator will start and come up to
speed. The generator circuit breaker will close, feeding the emergency bus and
switchboard.
Securing after “Loss of Load” Test
1.
Simulation “A”
a. Place the Engine mode selector switch from the “Auto” position into the “Manual”
position.
b. Open the Emergency Generator Circuit Breaker.
c. Recharge and close the 480-Volt bus-tie circuit breaker at the emergency
generator switchboard. This will reapply normal power to the Emergency
Switchboard.
d. At the emergency generator switchboard, place the engine mode selector switch
from the “Manual” position to the “Off” position, (after approximately 15 seconds
engine will stop).
e. Move the Engine Mode Selector Switch back into “AUTO” position.
f. Move the Emergency Generator Mode Selector Switch back to the “Normal”
position.
Simulation “B”
1. Close the circuit breaker P409 on 480-Volt Section in switchboard room. This will reestablish normal power to the supply side of the Emergency Switchboard Bus- Tie
breaker.
2. At the emergency generator switchboard, place the engine mode selector switch in the
“Manual” position.
3. Open the Emergency Generator Circuit Breaker on the emergency generator
switchboard.
4. Charge and close the Emergency Switchboard Bus-Tie Breaker, reapplying normal
power to the Emergency Switchboard.
5. At the emergency generator switchboard, place the engine mode selector switch from
the “Manual” position to the “Off” position, (after approximately 15 seconds engine will
stop).
6. Move the Engine Mode Selector Switch back into “AUTO” position.
7. Move the Emergency Generator Mode Selector Switch back to “Normal” position.
