3-5.3 Emergency shutdown
3-5.3.1 General. The barge has two emergency shutdown modes. One mode shuts down individual systems such as
the ventilation system or a diesel high pressure pump, and the other shuts down all barge operating systems.
Both modes are activated by pushing a red button protected by a metal guard. On individual system shutdowns,
either fuel or electrical power is shut off to that system only. On total shutdown, all fuel and electrical power is shut off to
all operating systems.
Seven red system shutdown buttons are located on the ROWPU space starboard bulkhead just aft of the
personnel door. These system shutdown buttons (Figure 3-10) control shore power, ventilation systems, ROWPU 1
diesel high pressure pump, ROWPU 2 diesel high pressure pump, ship auxiliary generator, ship service generator 1, and
ship service generator 2.
Six red total shutdown buttons are located as follows:
On ROWPU space starboard bulkhead aft of personnel door, above and forward of system shutdown buttons.
Outside ROWPU space starboard door on weatherdeck.
Outside ROWPU space port door on weatherdeck.
Inside ROWPU space port door to weatherdeck.
Outside dayroom door to weatherdeck.
Inside dayroom door to weatherdeck.
3-5.3.2 Emergency shutdown procedures
In an emergency, push the appropriate red button to shut down either a selected system or all operating systems.
When emergency situation has been corrected, reset emergency button by turning collar behind button one-
quarter turn clockwise. Button will pop out and again be in the ready position.
After emergency button is reset, any systems turned off by that emergency button must be restarted with their
Section IV. Operation under extreme conditions
3-6 Operation under extreme conditions. Operation of shore discharge system in extreme cold creates a special
problem with lubricants. Other problems occur during operation in extreme heat. These extreme conditions are
discussed below. Additional information is contained in the manufacturers' service manuals/instructions listed in Chapter
6. See TM 55-1930-209-14&P-21 for operation of shore winch under unusual conditions.
3-6.1 Operation in extreme cold
Heaters. When oil temperature is 45 degrees F or less, set heater ON/OFF switch (Figure 3-3) to ON. Make
sure heater indicator light comes on.
If hydraulic power unit motor does not start because temperature on weatherdeck is below 32 degrees F, it may
be necessary to jog starter button (Figure 3-3) so that warmer oil in hydraulic power unit warms oil in lines on
weatherdeck. If hydraulic power unit motor does not start after jogging starter button, it may be necessary to
heat hydraulic lines on weatherdeck.
3-6.2 Operation in extreme heat. Motors. Electric motors may have a tendency to run hot and stop due to overload. It
is best to allow the motor to start automatically after it cools off.
