DESCRIPTION/SPECIFICATIONS/WORK STATEMENT

1.0 Applicable to items: Grade “A” Feedwater is water that has been stripped of all impurities. The term

“feedwater” will be used hereafter to describe the end product meeting all requirements of the contract specification.

1.1 Capacity: The feedwater generating rigs shall be capable of processing not less than 80,000 gallons of water without regeneration when the average Total Dissolved Solids (TDS) does not exceed 300 Mg/L.

The maximum number of water treatment trailer systems in simultaneous use by the Government at any given time is six (6). The actual quantity will vary depending on the number of ships being serviced and the criticality of these services. As such, the sub-CLIN quantities identified herein are estimates only and are based upon historical data as well as current workload projections.

Estimated total gallons to be processed yearly are 1,920,000. This number may vary depending upon operation demands.

1.2 The rig shall be designed to operate with a fresh water inlet pressure of 25 PSIG to 100 PSIG with a maximum outlet flow rate of 120 GPM.

2.0 Freeze Protection

2.1 Freeze protection shall be provided by the contractor 365 days per year.

2.2 The Norfolk Naval Shipyard, Portsmouth, VA will provide a source of steam or electric power and the hoses or cables to hook-up freeze protection, when required.

2.3 Clearly legible, mercury free thermometers, to monitor inside temperatures, must be visible from outside the rigs.

2.4 Where steam is the method used for freeze protection, freeze protection devices must not exceed the following criteria:

2.4.1 115 VAC 60 Hz Single Phase.

2.4.2 460 VAC 60 Hz Single Phase.

2.4.3 460 VAC 60 Hz Three Phase.

3.0 Expectation Scale:

3.1 Prior to delivery of the first unit, the contractor shall provide, a chart, graph, or scales giving the limits in gallons of feedwater to be expected when the city’s water TDS exceeds the contract specifications.

4.0 Quality of Water

4.1 The contractor shall provide water within the following specifications:

4.1.1 Chlorides less than 0.1 PPM

Conductivity less than 1.5 MHOS/CM PH Range 6.0 – 8.0 Silica less than 0.1 PPM Visual clarity no turbidity, oil or sediment

4.2 The sample valve shall be situated prior to the flowmeter; hence the government shall not be required to pay for processed water expelled while obtaining a satisfactory sample.

4.3 Sampling:

4.3.1 The contractor shall provide to the Norfolk Naval Shipyard test facility routine water samples prior to the start of the regular work shift (07:20 AM to 3:50 PM) Monday through Friday. In addition to routine sampling, it may be necessary for the contractor to perform critical sampling outside of the normal working hours (Saturday, Sunday, holiday, etc.) when required by authorized NNSY personnel.

5.0 Protective Devices

5.1 The rig shall have a conductivity monitoring device in the outlet line which will activate audible and visual alarms when the conductivity reaches 1.5 UMHOS/CM. The monitoring device shall be calibrated by the contractor or other certified firms per the manufacturers' suggested schedule, not less than annually.

5.2 The rig shall be configured such that all pumping shall stop automatically when the conductivity goes out of specification.

5.3 It is recommended that rigs be provided with a device, such as a reverse phase relay, to correct any phase rotation incompatibility.

6.0 Required Features:

6.1 The units shall be equipped with an automatic internal recycling mode. When out of specification water is detected and regular pumping stops, the water should still continue to flush, either manually or automatically, internally, until the water returns to within specifications, or 500 gallons is recycled, whichever comes first. When the water comes back into specifications, a sample shall be taken and certified by the Norfolk Naval Shipyard test facility before pumping to the vessel can be resumed. If the water does not return to the desired specifications with the 500 gallon limit the rig shall be changed out.

6.2 The units shall have an external trouble indicator light, 5 – 15” in Diameter, Visible 360 Degrees, that is activated along with the audible alarm indicating that the units need attention.

6.3 All automatic shut-off devices shall be fail safe; that is; if power is lost they shall automatically switch to a closed position allowing no water to go to the vessel and will not operate until power is restored.

6.4 All gages, flowmeters, switches, and indicator lights shall be readily accessible for ease of on-site monitoring.

6.5 All gages, meters, and totalizers shall be calibrated by the contractor with a dated certification sticker attached to each item per the manufacturer’s suggested schedule or not less than annually.

6.6 The totalizer shall be accurate at various flow rates (eg: 30 GPM TO 200 GPM) even if more than one flowmeter has to be used.

6.7 The vendor shall provide training in safety and operation of units. The training will take place at the Norfolk Naval Shipyard between the hours of 7:20 A.M. AND 4:00 P.M. Four (4) mechanic level employees will be trained. The training to take place on the day of delivery of the demineralizer units. Training to take place when each new task order is placed.

6.8 There shall be a weather protected, schematic drawing showing the fluid flow, major components, cut off valves or breakers, etc., visibly affixed to the rig, for use in case of an emergency.

7.0 Applicable Items:

7.1 The contractor shall remove from the shipyard any expended unit or equipment identified by the shipyard. No payment will be provided for units remaining in the shipyard more than one (1) day (24 hours) after notification of exhaustion of the unit, to the contractor.

7.2 Regenerations:

7.2.1 The change out time shall not be greater than six (6) hours. This will, in most cases, permit removal and change-out of a rig within one eight (8) hour shift.

7.2.2 No changing of resin or demineralizer shall be performed at the Norfolk Naval Shipyard.

The contractor shall regenerate exhausted rigs at the contractor’s facility to operate at 100% of rated capacity. When the rigs are returned, the high point and low point drains and any connections shall be unclogged of resin, closed and or capped. The rated capacity is considered to be the amount of good resin required to meet the condition of paragraph

1.2 above.

7.2.3 The government shall prorate the cost per regeneration for any rig/unit failing to produce the contract requirement of a minimum of 80,000 gallons of feedwater. If a rig produces only a portion of the required amount of quality water, the government will pay only the applicable prorated portion of the regeneration fee.

7.2.4 If the TDS exceed contract specifications, the information provided as required by paragraph 3.0 shall be utilized. It shall be the contractor’s responsibility to provide the Contracting Officer with city data citing the TDS level for the time period in question.

Further as may be required, additional documentation shall be submitted to the Contracting Officer to support the contractor applying a regeneration charge for a rig producing less than the required minimum 80,000 gallons of feedwater. This information will then be used to evaluate any prorated amounts.

8.0 Applicable to Subline Items Contractor’s Responsibility:

8.1 An operator shall be available on site at the Norfolk Naval Shipyard for a minimum of 4 hours per day during week days, Monday through Friday, for sample taking, delivering feedwater, recycling, and rig maintenance.
