STATEMENT OF WORK (SOW)

FOR

Transformer Installation Between City Power and Shore-tie Receptacle

1.0 GENERAL

1.1 BACKGROUND

Coast Guard Cutter (CGC) WYACONDA operates on 240 VAC phase-to-phase and 120 VAC phase-to-ground electrical service. The existing city power configuration provided by Alliant Energy consists of a 120/120/208 VAC Wye/Delta transformer configuration, which has resulted in electrical compatibility issues when CGC WYACONDA is connected to the shore-tie receptacle.

The United States Coast Guard requires replacement of the existing city-owned transformer configuration with a 208Y/120 VAC Wye configuration. Following the utility metering point, a three-phase buck/boost transformer will be installed to provide the required 230–240 VAC phase-to-phase and 120 VAC phase-to-ground service at the shore-tie receptacle.

1.2 SCOPE

The Contractor must furnish all labor, materials, equipment, tools, supervision, testing, and documentation necessary to complete the transformer installation between the city power transformers and the shore-tie receptacle in accordance with this SOW.

1.3 OBJECTIVE

The objective of this SOW is to obtain a qualified contractor to install and integrate a three-phase buck/boost transformer system that provides the correct voltage and configuration required to safely and reliably supply shore power to CGC WYACONDA.

1.4 APPLICABLE DOCUMENTS

The Contractor must comply with the latest editions of the following standards, as applicable:

· NFPA 70, National Electrical Code (NEC)

· IEEE 45, Recommended Practice for Electrical Installations on Shipboard

· MIL-STD-1399, Section 300, Interface Standard for Shipboard Systems – Electric Power (where applicable to shore interface)

· IEEE C57, Standards for Transformers

· OSHA 29 CFR 1910, Electrical Safety

· Local Authority Having Jurisdiction (AHJ) requirements
