Components of this system are listed in Table 2-1 and shown in engineering drawings listed in Appendix A.
2-2.
Capabilities. This system provides electrical power for operating barge equipment. Either of two 155 kW SSG’s
provides sufficient electrical power to operate all systems onboard. The SAG provides sufficient power for barge occupancy
but not for major ROWPU systems operation. When onboard generator sets are not operating, power can be supplied
through the shore power receptacle from onshore or from another vessel. An emergency shutdown system is also provided
to stop individual systems or to stop all electrically powered equipment onboard. Paragraph 2-18 provides additional
information.
2-3.
Special limitations. This system must have sufficient fuel for diesel-powered generators and the generators must
be operational.
