7-15.5 Emergency shutdown
7-15.5.1 General. The barges have two emergency shutdown modes (Chapter 3). 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.
Emergency system shutdown red buttons are on the ROWPU space starboard bulkhead just aft of the personnel
door. These seven emergency system shutoff buttons (Figure 3-16) control shore power, ventilation systems, ROWPU 1
diesel HP pump, ROWPU 2 diesel HP pump, SAG, SSG1, and SSG2.
