Spec #: Topside Diesel

Rev: - Page 1 of 5

STATEMENT OF WORK FOR RENT

1. SCOPE

1.1. A diesel-powered portable Tier 4 Final generator with a built-in fuel tank to be deployed on top of a submarine. Topside generators are considered to be PRIME power rating for the duration of power operations.

2. APPLICABLE DOCUMENTS

2.1. Issues of Publications - The following documents of the issue date in effect on the date of request for proposal form a part of this specification to the extent applicable, or as specified herein. Within the specification, they shall be referred to by their basic designation only.

2.1.1. Government

2.1.1.1. N/A

2.1.2. Nongovernment

2.1.2.1. N/A

2.2. Order of precedence - In the event of conflict between the text of this specification and that of the references cited above, the text of this specification shall take precedence.

Nothing in this specification, however, shall supersede applicable laws or regulations unless a specific exemption has been obtained.

3. REQUIREMENTS

3.1. Electrical Output

3.1.1. Output shall be ungrounded power (sometime called ‘floating the ground’ or

‘isolating the neutral’) three-phase and based on a 0.8 power factor (lagging).

3.1.2. Output voltage must be variable by qualified shipyard mechanics between 450 and 480 VAC at 60 Hz. Power shall be as described below across the voltage range.

Amperage would be approximately 502 amps fully loaded @ 460V and 0.8PF in

Prime.

3.1.3. The minimum prime power output shall be 320 kW (400 kVA).

3.1.4. The insulation rating of the diesel generator windings to ground must exceed five meg-ohms. This is important because ship’s power is ungrounded. Also, because the source of unwanted grounds in a diesel generator is largely the control/metering circuitry; ensure that all control/metering circuits are located on the secondary side of a power transformer away from the power circuits that feed the boat. Provide drawing(s) with the proposal showing how the transformers are used to ensure grounds feeding the submarine are kept above 5 megohms.

3.1.5. Diesel generator frame must be grounded.

3.1.6. Safety devices must be typical for commercial units including the output circuit breaker.

3.1.7. If so equipped, the long-time trip setting of the output breaker shall be set approximately 15% above full load when at a 0.8 PF.

3.1.8. If so equipped, the short term and instantaneous trips shall be set to high.
