9-17 Emergency shutdown
9-17.1 General. The barge has 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.
Seven red system shutdown buttons are located on the ROWPU space starboard bulkhead just aft of the personnel
door. These system shutdown buttons (Figure 3-16) control shore power, ventilation systems, ROWPU1 diesel HP pump,
ROWPU2 diesel HP pump, SAG, SSG2, and SSG1.
