SECTION II. Description of operation
4-9. Description of operation. Normal electrical power for barge operations is supplied by one of the two SSG’s. By
transferring loads between generator sets, barge operations can continue without interruption. While any two of the three
generators onboard can be operated in parallel, this procedure is for load transfer only and not for continuous operation. To
transfer the electrical lead from one generator to another, start the unused generator. After warm up, parallel its load with
the current loaded generator and transfer the load (paragraph 2-14). Run down, cool off, and shut down the now unused
generator. This paralleling and transferring of electrical load can be done between the 20 kW auxiliary generator and either
of the two SSG’s or between SSG’s.
