Scope of Work

USCGC POLAR STAR (WAGB-10)

Troubleshooting and Repair of OWS Flow Totalizer

1. Purpose The contractor shall provide all labor, supervision, tools, test equipment, incidental materials, travel, and technical support necessary to troubleshoot and repair the Oily Water Separator (OWS) flow totalizer system aboard USCGC POLAR STAR and restore proper receipt, display, and totalization of the overboard flow signal by the PureBilge system.

2. Place of Performance Aboard USCGC POLAR STAR (WAGB-10), Seattle, Washington.

3. Background The vessel has an OWS flow totalizer casualty associated with the PureBilge system and installed flow meter/transmitter. The flow meter reportedly shows local activity, but the PureBilge control system is not properly receiving, displaying, or totalizing the overboard flow signal. Remote troubleshooting has been attempted without resolution. Onboard troubleshooting and repair are required.

4. Firm-Fixed-Price Requirement This is a firm-fixed-price requirement.

The firm-fixed price shall include all costs necessary to complete the work defined in this scope, including labor, supervision, travel, per diem, tools, diagnostic equipment, testing, incidental materials, minor electrical materials, report preparation, and all other costs required to complete the defined troubleshooting, repair, and testing eƯort.

The contractor shall complete all work within the repair boundaries defined herein for the fixed price quoted.

5. Scope The contractor shall inspect, troubleshoot, test, adjust, reconfigure, reconnect, and repair the existing OWS flow totalizer signal path and associated components as necessary to restore proper functionality within the repair boundaries of this scope.

The fixed-price scope is limited to the following:

Diagnosis of the failure of the PureBilge system to receive, display, or totalize the overboard flow signal.

Inspection of the installed flow meter/transmitter, signal wiring, terminals, power supply, and associated PureBilge control system interface.

Verification of wiring continuity, terminal correctness, signal path integrity, polarity, grounding, scaling, and configuration.

Verification of meter output type and receiving input compatibility.

Adjustment, recalibration, reconnection, retermination, minor rewiring, parameter configuration, and minor repair necessary to restore system operation.

Functional testing after repair to verify proper system operation.

This fixed-price scope does not include:

Replacement of major components.

Replacement of the flow meter/transmitter.

Replacement of the PureBilge control unit, PLC, HMI, or major electrical assemblies.

Piping modification, fabrication, welding, hot work, or structural alteration.

Major cable replacement beyond minor local repair at the aƯected connection points.

Work on unrelated PureBilge or OWS casualties.

Additional corrective action outside the aƯected flow totalizer signal path.

If the contractor identifies a condition requiring work outside this fixed-price scope, the contractor shall stop, notify the Government, and provide written findings and recommendations. No out-of-scope work shall be performed without written Government authorization.

6. AƯected Equipment The work applies to the following aƯected equipment and interfaces:

PureBilge 5015S system

Installed overboard flow meter/transmitter identified in prior troubleshooting as Flomec RT40

Associated OWS flow totalizer signal wiring, terminals, and control interface

Associated configuration parameters required for signal receipt, display, and totalization

7. Contractor Tasks The contractor shall:

Inspect the aƯected OWS flow totalizer installation and associated control system interface.

Review available drawings, prior troubleshooting information, and vendor correspondence provided by the Government.

Verify physical installation conditions that may aƯect performance, including flow direction, pipe-full condition, bypass condition, and connection integrity.

Verify that the installed signal wiring is correctly landed and compatible with the receiving PureBilge input.

Verify the presence and adequacy of required power, grounding, and polarity.

Verify signal type, scaling, and configuration settings aƯecting totalizer functionality.

Perform diagnostic testing necessary to isolate the fault to the meter, wiring, terminal connections, signal configuration, or control interface within the repair boundary of this scope.

Perform in-scope corrective actions, including reconnection, retermination, minor rewiring, parameter adjustment, calibration, and minor repair needed to restore functionality.

Conduct post-repair functional testing to verify proper signal receipt, display, and totalization by the PureBilge system.

Document all findings, repairs, settings changes, and test results.

8. Materials The contractor shall furnish all labor, supervision, tools, test equipment, and incidental materials required to complete this fixed-price scope.

Minor consumables and incidental electrical materials required to complete reconnection, retermination, or minor repair shall be included in the fixed price.

The Government will not reimburse separately for incidental materials, travel, testing, reporting, or other costs required to complete the defined scope.

9. Government-Furnished Support The Government will provide:

Access to the vessel and aƯected equipment

Escort and shipboard coordination as required

Available casualty history, drawings, and prior troubleshooting correspondence

Approval authority for any work determined to be outside the fixed-price scope

10. Deliverables The contractor shall provide:

Onboard troubleshooting and repair support

Functional test results demonstrating system status at completion

A written service report documenting:

o Observed condition o Cause of failure, if determined o Diagnostic steps performed o Repairs or corrections made o Configuration settings changed o Test results o Final operational status o Any recommended follow-on action outside this scope

11. Acceptance Criteria Work shall be considered complete when all of the following are met:

The contractor has completed troubleshooting suƯicient to isolate the casualty within the aƯected system boundary.

All in-scope corrective actions required to restore function have been completed.

The PureBilge system successfully receives the overboard flow signal from the installed flow meter/transmitter.

The PureBilge system properly displays and totalizes overboard flow during functional test.

All repairs, adjustments, and configuration changes are documented in the final service report.

The contractor has identified any remaining deficiencies, if present, that are outside this scope.

12. Constraints and Assumptions This firm-fixed-price scope assumes:

The aƯected equipment is accessible for inspection and testing.

Ship’s force or Government personnel will provide normal access, escorts, and operational coordination.

The casualty can be corrected through troubleshooting, configuration, reconnection, calibration, or minor repair within the existing system arrangement.

No major component replacement or major system redesign is required.

If hidden conditions or equipment failure outside the defined repair boundary are discovered, those conditions shall be treated as out of scope and shall require separate written Government authorization.

13. Period of Performance

TBD.

14. Pricing Instructions OƯerors shall submit one firm-fixed price for the complete scope described herein.

OƯerors may separately identify recommended optional parts or out-of-scope corrective actions, but such items shall not be included in the firm-fixed-price base unless specifically requested by the Government.
