REFERENCES

1. Glosten Drawing No. 19005-1-300-01 Electrical One-Line Diagram, Rev -, 2019/06/07

2. Navsea Design Data Sheet, Department of the Navy, "Electrical System Load and Power Analysis for Surface Ships"

PREPARED FOR

1. This document has been developed from information in References 1-2.

2. Definitions and acronyms DF: Demand Factor, defined as the fraction of time that the load is operational in an operational profile.

ekW: Electrical kilowatts FLA: Full Load Amperes HP: Horsepower kVA: Kilo Volt-Amperes Utilization Factor: the fraction of the connected load rating that is utilized during normal operation.

V: Voltage Φ: Number of phases UVT:Undervoltage trip

3. Calculation procedure: Profile Load = Connected * Utilization Factor * Demand Factor

4. Two generators supply power to one main bus at 208VAC, 60Hz, 3PH. This bus supplies power to the 208/120VAC Ship Service Switchboard. The generators can be automatically paralleled from the Pilothouse.

5. This load analysis includes a 10% design margin and 5% growth margin for the vessel.

6. This load analysis considers two primary seasons, winter and summer. In the summer, all cooling loads are evaluated, while in the winter, all heating loads are evaluated.

7. This loads analysis considers four operating profiles. These include transit, to represent the electrical demand during regular movement of the vessel. Operational, to represent when the vessel is 'working', operating either the crane or the winch. Shore power, to represent when the vessel is alongside and supported by the shoreside infrastructure. In this case, neither generator is online and no there are no overnight crew. It is assumed that if the crew is staying overnight on the vessel, one generator will be supporting the additional house loads. While on Shorepower, the winter season represents the worst case and loads are limited to vessel heating and battery chargers. And finally, Emergency, to represent only loads required by USCG regulations to be operational during an emergency.

8. Shore power is available at 208VAC, 3ph, 100A.

9. This loads analysis shows the most demanding load season is the summer, while the heat pumps are providing cooling and all ventilation fans are running on full load. In this case, one generator can support the vessel during regular transit, loaded to 75%. During the summer operations load case, the vessel will require both generators to share the electrical demand. Both generators will be operating at approximately 65%.

10. The system is configured with one Load Shed Panel. This panel provide power to non-vital heating and cooling appliances and can be de-energized to enable the vessel to perform summer operations on one generator. The engine room supply fan are not on this panel, and will continue to provide cooling and combustion air even in a load shed scenario.

11. All required emergency lights have integral battery backup power. They are not shown on the Emergency load case.
