2-14 Emergency shutdown
2-14.1 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 mode shuts down all barge operating systems.
Both modes are activated by pushing a red button protected by a metal guard. On individual system shutdowns, this
button shuts off either fuel or electrical power to that system only. On total shutdown, this button shuts off all fuel and
electrical power to all operating systems. Any system emergency shutdown that stops a generator supplying power to the
switchboard will also shut down the anchoring system.
Seven red system shutdown buttons are located on the ROWPU space starboard bulkhead just aft of the personnel
door. These system shutdown buttons (Figure 2-5) control shore power, ventilation systems, ROWPU 1 diesel high
pressure pump, ROWPU 2 diesel high pressure pump, ship auxiliary generator, shipservicegenerator2, and ship service
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 shutdown
Outside ROWPU space starboard door on weatherdeck.
Outside ROWPU space port door on weatherdeck.
Inside ROWPJU space port door to weatherdeck.
Outside dayroom door to weatherdeck.
Inside dayroom door to weatherdeck.
2-14.2 Emergency shutdown procedures
a. In an emergency, push appropriate red button to shut down either a selected system or all operating systems.
b. 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.
c. When emergency button is reset, prepare anchor winches for use by following procedures in paragraphs 2-10 and
Operations under extreme conditions
For operations in extreme humidity, winch motors and electric brakes have built-in electric heaters that are
effective in reducing corrosion damage.
For operations in extreme high temperatures, electric motors may become overheated from a combination of
high ambient temperatures and heavy use, and winch panel circuit breaker may break to open. Push RESET button on
anchor winch control panel. If circuit breaker continues to break to open, turn off electric heaters by opening power panel
3 circuit breaker 11P13. If anchor winch panel control circuit breaker continues to trip to open, allow motor to cool and
consider other methods of retrieving anchor to reduce load on winch motor.
For operation in extreme cold, use cold weather lubricants. Keep winches clear of snow and ice. Turn on
winch motor heaters at least 30 minutes prior to using winches.
