Rev (A) Page 2 of 9

3.1.2. The voltage and wiring of the load bank shall be as follows:

3.1.2.1. 450VAC, 3-Phase, 3-Wire

3.1.3. The load bank shall have a digital load controller. The minimum step resolution shall be no greater than:

11.3KW/8.5 KVAR @ 480VAC

3.1.4. The load bank shall be freestanding, semi-portable, and have a self-contained load module. The load bank shall include crane lifting eyes, forklift channels, a heavy skid base, and a lifting sketch shall be provided. Load bank shall perform initial testing of rented diesel generator.

3.2. Diesel

3.2.1. The Diesel generator with a Tier 4 engine shall be capable of running, without being refueled, for a minimum of twelve (12) hours in duration at a minimum of 1000 kW (1,250 kVA) and maximum of 1,250KW/1,562.5KVA STANDBY power. It shall be capable of being refueled while in operation.

3.2.2. Vendor shall provide all manuals and specification sheet at proposal period for technical review.

3.2.3. For pricing purposes, the generator should be assumed to be secured unless of a loss of power, or the threat of a loss of power or being tested.

3.2.4. When operating at full speed, noise levels shall not be over 85 dB[A] at three feet from the unit.

3.2.5. The trailer for the diesel shall be in operational readiness condition and be capable of being moved by tractor or mule. If the diesel generator is equipped with an auxiliary fuel tank (i.e. UL 142 Double Wall Tank Assembly), the tank shall fit entirely within the CONEX box.

3.2.6. The diesel generator shall be capable of being lifted by crane (i.e. a four-point lift).

A Lifting & Handling diagram/sketch that is applicable to the situation shall be provided.

3.2.7. Output shall be ungrounded (commonly referred to as ‘floating the ground’ or ‘isolating the neutral’) three-phase power (when an isolation transformer is used, the diesel shall be grounded and the isolation transformer will be ungrounded on the secondary side). Output voltage shall be variable between 450 and 480 VAC at 60 Hz, while maintaining the rated power levels. The maximum STANDBY amperage for a 1000KW generator will be approximately 1,568A (@ 460V, 1000 kW and a 0.8PF).

Rev (A) Page 3 of 9

Therefore, the generator’s breaker shall be set to trip on long-time delay at between approximately 1,568A (higher for larger generators, but not to exceed 1,600A). Also, the instantaneous trips shall be HIGH to allow for in-rush currents.

3.2.7.1. The Diesel Generator SHALL have at least one 120 VAC, 15 Amps, single-phase power receptacle available for string lighting when the diesel generator is (or, is not) running or have internal lights sufficient to illuminate the controls when the diesel generator is (and is not) running.

Diesel generator frame SHALL be grounded.

3.2.7.2. The 120 VAC power shall be grounded. Grounded power must be isolated from the 480 VAC ungrounded power.

3.2.7.3. Diesel Generator Power Limiter State parameter (if applicable) SHALL be set to “STANDBY.”

3.2.7.4. Vendor shall provide OQE Objective Quality Evidence that a 100 percent load test has been performed within the last 30 days of arrival. If data cannot be provided vendor shall perform load test on site after arrival.

3.3. Isolation Transformer

3.3.1. Because the diesels in San Diego have not been able to provide a ground reading in excess of 5 megohms recently; provide an additional isolation transformer where the diesel’s side of the transformer shall achieve 1 megohm to ground (prior to connection to the grounded diesel), and 5 megs to ground on the side toward the ship (also prior to connection). The isolation transformer shall be large enough to transmit the entire power of the generator from the primary side to the secondary side over the 450 to 480VAC voltage range. As a minimum, the transformer needs to be at least 1,062.5 KVA and at least as big as the KVA of the diesel (whichever is bigger). Small physical size is an advantage.

3.4. Connections

3.4.1. Lugged connections are acceptable as well as compression fittings (lugged connections are preferred).

3.4.2. When lugs are used, the unit must accept Thomas and Betts 600 Two Hole Green 94 lugs. When lugs are not used, the unit must accept SHOF-500 fine-stranded cables in compression fittings.

3.5. Footprint

The platform that the diesel generator will be placed on is space limited. Diesel generator packages with small physical dimensions are an advantage. If the diesel comes in two (2) parts (diesel with external fuel tank), the dimensions of both parts are required. The overall width shall not be greater than eight (8) feet. The diesel generator shall be delivered with a quantity of diesel fuel sufficient to run for at least twelve (12) hours in duration at a load of 1000 kW (1250 kVA).
