Performance Work Statement (PWS)

Pearl Harbor Naval Shipyard

And Intermediate Maintenance Facility

Rectifier Unit, Model #12DC-3000-365-480-TF

Modification Services

1. BACKGROUND:

1.1. Pearl Harbor Naval Shipyard & Intermediate Maintenance Facility (PHNSY & IMF) is a

US Navy regional industrial center that maintains, overhauls, and repairs various vessels of the US Navy. Its industrial operations provide the US Naval forces with a wide range of services and resources located on the island of Oahu, Hawaii, with direct and indirect support to SSN 688 and 774 class submarines, surface vessels, and shore based activities in the Pacific.

2. OBJECTIVE & SCOPE:

2.1. PHNSY & IMF seeks a Contractor to provide repair and modification of the Rectifier

Unit, Model #12DC-3000-365-480-TF, to a fully operational condition, in accordance with performance requirement specifications.

3. PERFORMANCE REQUIREMENTS:

3.1. The Contractor shall supply and authorize, an Original Equipment Manufacturer (OEM), Trained Technician and not a subcontract technician, to perform all the following services:

3.2. Modification: The Contractor shall provide all management, labor, tools, materials, supplies, equipment and transportation to troubleshoot, repair, modify, and test Rectifier

Unit, Model #12DC-3000-365-480-TF, in accordance with current OEM guidelines, at the Contractor’s facility. After required modifications are completed at the Contractor’s facility, the Contractor, prior to shipping shall:

3.2.1. A. Complete a Full Uninterrupted Satisfactory Load Test in accordance with DC

Rectifier PHNSY Load Table below.

3.2.2. B. Test functionality of all modifications specified.

3.2.3. C. Perform a comprehensive visual inspection of major internal and external components, to establish a base-line condition.

These requirements shall be captured by an “At Origin” Test Procedure Document that will be developed by the Contractor and reviewed and approved by PHNSY & IMF prior to execution. This document must be completed, dated, and signed prior to shipping, to certify that all performance criteria identified in A-C, above, was met. After the unit is shipped, these same tests, A-C will be repeated and documented at PHNSY & IMF and will serve as the “At Destination”, certification and acceptance. The contractor at no cost to the Government is responsible to repair areas identified that does not meet A-C above. “At Destination” testing, all support equipment, AC Shore power, AC and DC cabling and DC load banks shall be provided by Pearl Harbor Naval Shipyard & IMF.

The Modifications required are detailed below:

3.2.4. Rectifier must be able to pass load testing per “DC Rectifier PHNSY Load Table” below, especially at 210VDC. The rectifier must be able to perform a continuously uninterrupted run (1-8) at 210VDC, 270VDC and 355VDC voltages without shutting down unexpectedly. If the vendor cannot achieve 4 hour hold at 210VDC, 2800ADC, then run test for 1 hour.

*If 4 hour hold test cannot be achieved, then 1 hour hold test will be acceptable.

3.2.5. Correct stability problem to achieve 3 seconds or less voltage recovery when going from fully loaded to fully unloaded, eliminating voltage spiking effect; currently, when going from the loaded to fully unloaded state, DC voltages will spike to a higher value then takes > 10 seconds to return to original value.

3.2.6. Install visual indication warning circuit for Over temperature (OT), and Over current (OC). Prior to regulator shutting down, due to either fault, OT warning shall monitor all power magnetic components (XFMR1, IPT, L1 and SCRS). OC warning circuit will monitor the DC output bus. Both warning (OT/OC) indications shall be adjustable within a range not detrimental to affect rectifier performance.

These features provide operator the ability to adjust DC load during operation to prevent unnecessary shut down of rectifier. In the event a shutdown occurs, a visual indication shall provide user a root cause of the fault (OC/OT).

3.2.7. Install Digital DC Voltmeter vice analog. If this cannot be accomplished due to degradation of insulation resistance, install test points where the user can install an external voltmeter in conjunction with its existing analog voltmeter.

3.2.8. Install remote controller with minimum length, 50 ft. cable with connector ends

(not hard-wired). Install remote controller to allow Opening/Closing of input and output breakers, adjustment of DC output voltage and to be able to view DC voltage, and current, remotely. Also installed with indication lights, for warnings and faults of (OT/OC).

3.2.9. Install NEMA 4X rated Weather resistant cover for control panel. This is to prevent rain and seawater mist from getting inside the DC rectifier. Area of protection includes front portion where indicator lights and control knobs reside.

3.2.10. Modify space heaters/control circuit to be user controlled (manual). Install manually switchable space heaters to reduce moisture caused by rain and harsh weather conditions. Space heater shall de-energize when DC rectifier output breaker closes via interlocked circuit.

3.2.11. After all modifications are performed the DC rectifier cannot change the following behaviors from its original design:

3.2.11.1. The DC rectifier must be able to withstand starting surges up to 3500ADC for at most 2s at 270VDC without shutting down the DC Rectifier. This was proven to be satisfactory for Type 2 in the DC rectifier’s original state.

Starting surge specifics:

Type 1: L1-2200A (decays to 1200A in 1s), M1-2500A (decays to 1500A in

1s), M2-2900A (decays to 100A to 2s).

Type 2:2000A (decays to 1300A in 1s), 2600A (decays to 1500A in 1s), 2100A decays to 700A in 3S, 1100A (decays to 150A in 1s).

3.2.11.2. The DC rectifier insulation resistance must still be greater than or equal to

50 Megohms. The combined insulation resistance to ground shall be 50

Megohms or greater without temperature correction. Insulation resistance shall be measured by manually closing the DC output breaker then jumpering

+ and – output busses together and measuring insulation resistance from + or – to chassis frame ground (FG) using a 500V megger.

3.2.11.3. Output ripple shall be no greater than 5% RMS @ Full load @ 210, 270, 355VDC.

3.2.11.4. When increasing/decreasing loading of DC rectifier, the DC voltage regulation must be maintained per original specifications. Currently DC voltages does not vary more than 0.5% from load changes (except when unloading fully).

3.2.12. Transformer weight addition, Center of mass, lifting and handling must be clearly defined prior to start of rectifier modification. Vendor will provide weight changes, and new center of mass and report any lifting and handling changes.

3.2.13. Revise the current Technical Manual to incorporate new modifications.

3.3. Reports: The Contractor shall provide an “At Origin” Test Procedure Document that includes a completed, Full, Uninterrupted Satisfactory Load Test in accordance with DC

Rectifier PHNSY Load Table, Test Functionality results of all specified modifications, and a Comprehensive Visual Inspection of major internal and external components, to establish a base-line condition. The document must be reviewed and approved by

PHNSY & IMF, prior to execution.

This document must be completed, dated, and signed prior to shipping, to certify that all performance criteria identified above, was met. After the unit is shipped, the same tests will be repeated and documented at PHNSY & IMF and will serve as the “At

Destination”, certification and acceptance. The contractor is responsible to repair areas identified that does not meet the requirements of the test procedure document. “At

Destination” testing, all support equipment, AC Shore power, AC and DC cabling and

DC load banks shall be provided by Pearl Harbor Naval Shipyard & IMF.

3.4.
