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 3-4) control shore power, ventilation systems,
ROWPU 1 diesel high pressure pump, ROWPU 2 diesel high pressure pump, ship auxiliary generator,
ship service generator 2, and ship service generator 1.
Six red total shutdown buttons are located as follows:
On ROWPU space starboard bulkhead aft of personnel door, above and forward of row of system
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.
Emergency shutdown procedures
In an emergency, push appropriate red button to shut down either a selected system or all operating
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 ready position.
When emergency button is reset, restart seawater system according to procedures in Chapter 3.
Section IV. Operation under extreme conditions
Operation under extreme conditions. Operation of seawater 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 manufacturers' service manuals/instructions listed in Appendix B.
Operation in extreme cold. Cold weather lubricants must be used. Drain system if there is any danger of
Operation in extreme heat. Hot weather lubricants must be used. Electric motors have a tendency to run hot in
high temperature areas. Electric motors contain internal circuits that automatically stop the motor before it gets hot
enough to bum circuitry and bearings. When extreme internal heat triggers this automatic cutoff, allow the motor to cool
before attempting to restart it.
