Diesel Powered Portable Skid Mounted Enclosed Generators

Statement of Work

Strategic Weapons Facility Pacific (SWFPAC), Code SPB14

Scope of Work: The contractor shall provide, unpack and deliver in-place two (2), enclosed Diesel Powered Portable Skid Mounted Generator-Sets with power cable connections to United States Coast Guard Airstation/SFO Port Angeles, 1 Ediz Hook Road, Port Angeles, WA 98362. Prior to delivery contractor shall remove and dispose of (2) currently installed 50kW generators. Contractor shall coordinate delivery, installation, connection and operational testing of (2) new generators with Government Point of Contact (POC). Contractor shall submit detailed specifications and recommended origninal equipment manufacturer (OEM) maintenance for proposed generators. Contractor shall provide 12 months of OEM recommended maintenance following installation and successful testing, to be performed on-site. Maintenance may be extended up to 1 time for an additional 12-month period.

Period of Performance: Once awarded, contractor will provide equipment specified by this contract within 6 (six) months from award date.

Deliverables:

• Diesel Generator #1
  
  
  
  
  1. Rating shall be 50 kW, three phase, four-wire, 480 VAC line voltage, 277 VAC phase voltage, with a continuous power factor of 0.8.
  
  
  2. The load under normal conditions is approximately 18 kW. A single 7.5 horsepower three-phase sewage lift pump motor will be called upon intermittently as an addition to this normal load.
  
  
  3. Contractor may recommend a diesel-generator rating lower than the recommended 50 kW @ PF=0.8 is viable to avoid unnecessary 'wet-stacking' of the diesel during times when the lift pump is not operating, i.e., 18 kW.
  
  
  4. Contractor shall provide connection cable compatible with transfer switch in Enclosure (1).
  
  
  5. Diesel-generator shall be able to start sewage lift pump motor directly across the line without causing an unacceptable voltage drop to the system. The specific technical cut sheets for the sewage lift pump motor are attached as Enclosure (2).
  
  
  6. Diesel-generator shall have the capability to auto-start via an automatic transfer bus/switch for future capability.
  
  
  
  

• Diesel Generator #2

1. Rating shall be 50 kW, three phase, four-wire, 480 VAC line voltage, 277 VAC phase voltage, with a continuous power factor of 0.8.


2. The load under normal conditions is approximately 18 kW. A single 7.5 horsepower three-phase sewage lift pump motor will be called upon intermittently as an addition to this normal load.


3. Contractor may recommend a diesel-generator rating lower than the recommended 50 kW @ PF=0.8 is viable to avoid unnecessary 'wet-stacking' of the diesel during times when the lift pump is not operating, i.e., 18 kW.


4. Contractor shall provide connection cable compatible with transfer switch in Enclosure (1).


5. Diesel-generator shall be able to start sewage lift pump motors directly across the line simultaneously without causing an unacceptable voltage drop to the system. The specific technical cut sheets for the sewage lift pump motors are attached as Enclosure (3).


6. Diesel-generator shall have the capability to auto-start via an automatic transfer bus/switch for future capability.

• Power Cable Connections
  
  
  
  
  1. Provide 2 power cables, one for each generator.
  
  
  2. Power cables shall be of an appropriate rating such that they can handle the full capacity of the generators.
  
  
  3. Cables shall be compatible with the transfer switch connection specified in Enclosure (1).
  
  
  4. Cables shall be at least 20 feet in length.
  
  
  
  

• Equipment provided shall meet or exceed the following requirements:
  
  
  
  
  1. Generator shall be an all season operating system, portable diesel-generator set designed and constructed for outdoor use in the Pacific Northwest region, situated in an environment adjacent to salt-water and unshielded from all potential types of weather including windblown rain and snow. Enclosure to have drainage.
  
  
  2. Generator shall have a fully lockable enclosure to allow safe unattended operation.
  
  
  3. All aspects of their diesel-generator set including the excitation equipment, voltage regulator, and governor will perform properly under the following transient loading conditions: Assume that the diesel-generator set is supplying a steady-state load of 35 kW (44 kVA @ P.F. = 0.8) at which time the sewage lift pump induction motor (480 VAC, three-phase, 7.5 horsepower) starts directly across the line at full voltage, i.e., without soft-starting equipment.
  
  
  4. The generator shall be capable of running for an indefinite period of time with the 'normal' phase imbalance of Phase A=9.26 kW, Phase B=7.24 kW, Phase C=1.59 kW in addition to the lift pump motor in Enclosure (1) running and will not cause damaging negative sequence heating beyond the generator thermal capabilities.
  
  
  5. Generator shall have a tank capacity to support at least 12 hours of continuous, full rate operation before refueling is required.
  
  
  
  

• Maintenance Description
  
  
  
  
  1. Maintenance shall include but it not limited to the following maintenance actions:
     
     
     
     1. Monthly operational check of at least 30 min (per OEM guidance)
     
     
     2. Monthly fluid level check and top off as necessary (per OEM guidance), to include:
        
        
        
        1. Fuel
