28--Provide all labor, materials, equipment and parts to remove the generators on the floating crane CHOCTAWHATCHEE, and replace with a remanufactured CAT 330B 174kw generator set or newer model.

Contractor to remove the starboard generator of the CHOCTAWHATCHEE (a floating crane), and replace it with a remanufactured CAT 3306B marine generator or a newly remanufactured Caterpillar generator set of equivalent power within the following range: Caterpillar Generator Set 3306B (170 ekW 213kVa 60Hz @1800 rpm) - (190 ekW 238 kVa 60 Hz @1800 rpm). General characteristics of the crane are: Length - 165'; Beam - 50', molded depth amidships -11'-6"; and displacement -1,221 long tons. Due to the current sound and weatherproof enclosures an identical model remanufactured unit is desired and any other model offered must fit inside the existing enclosures and utilize the existing radiators and mounting arrangement. A Caterpillar remanufactured unit is required to provide interoperability and sharing of common parts and consumables (filters, belts, seals, oils, etc) with the remaining 3306B generator set on board the CHOCTAWHATCHEE. With a remanufactured 3306B generator set the fuel delivery system, which includes the injection pump, injectors and governor, must be new parts. The contractor will reuse the existing radiator but will have the unit flushed and cleaned per the manufacturer's recommendations. The contractor will remove and re-install the generator's enclosure and all covers. Lifting and setting of the enclosure will be made by the Government with a Government crane with proper coordination with the contractor. The contractor will disconnect and re-connect all wiring, fuel lines, etc. and insure that the replacement generator is fully operational. The crane barge will be operational during this work, therefore the contractor must ensure that the starboard generator is completely disconnected from the barge's main electrical bus to avoid any accidental re-energizing of the work area until the starboard generator is ready for reconnection and testing. The contractor will insure that the port generator remains operational at all times during the work. The contractor will perform a load test on the remanufactured or new generator set to ensure it will operate without any detrimental effects to the generator or barge.
