NOTE 8: The ship does not have automatic load shedding capability. There are three generators capable of supplying ship's service loads. With the largest generating source stopped the combined capacity of the remaining ship's service generating sources are sufficient to supply those services necessary tp provide normal operational conditions of propulsion and safety in accordance with 46 CFR 111.10-4(b).
NOTE 9: The electrical system configuration allows for continuous parallel operation of the Auxiliary Diesel Generator with the Ship's Service Tubine Generators (SSTG). Load sharing lines and cross current compensation are provided to ensure real and reactive load sharing meets ABS requirements.

NOTE 2: An allowance has been made on Panel EL101 and EL105 to account for fire alarm panel and sprinkler alarm panel. Load data used is comparable to data found on ships of similar size.
NOTE 3: An allowance has been made on panel EP401 to allow for the relocation of circuit 11EP-402, elec. Hydr door at shaft alley.
NOTE 7: The load on the Emergency Generator will be monitored during this backfeed condition and upon overload condition the bus tie breaker will be tripped sheding all non emergency loads.
NOTE 4: An allowance has been made for the transitional source of power. The load has been added only to the main swbd since the emergency generator will not see the UPS load when the unit is in operation.
NOTE 5: The load value added for the transitional source of power is equivalent to the difference between the emergency 120 volt load and the transitional source's efficiency.
NOTE 1: The kW value reflects the pumps design operating point.
NOTE 6: The load values for the black ship are the loads required for the start up of the main boilers, SSTG and the
Aux Engine. It will also be assumed that many of the emergency loads remaining will not be inoperation.
