CHAPTER 4 EMERGENCY SHUTDOWN
4-1 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 systems are operated by pushing a red button protected by a metal guard. On 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 and the lighting system. Any system emergency shutdown that stops a generator supplying power to the
switchboard also turns off the lighting system.
When the lighting system is off because of an emergency shutdown situation, emergency interior lighting is provided
by the 24 Vdc battery bank (paragraph 2-9.2). Exterior lighting requirements are provided automatically from the 24 Vdc
battery bank to the shore discharge hose deployment status lights, the anchor light, and the navigation running lights
when these lights are turned ON at the 24 Vdc power panel.
