NAVSEA 08K

• Responsible for the development, manufacture,
  installation, testing, operation, and maintenance
  of
• Reactor Plant IC equipment and systems used to
  monitor and control the reactor plant.
• Steam and Electric Plant IC equipment and
  systems used to monitor and control the main
  engines and electric plant.

Background

• What are we trying to fix?
• Maintenance personnel have difficulties in
  identifying meter equivalencies
• Increasing number of GPETE models called out by
  08 procedures are obsolete
• Test equipment called out in technical manuals
  may not have the procedures required for
  calibration
• Equipment technical manuals lacking test
  equipment definitions

4
Fix Use the NAVSEA 04 process

• Use SCAT codes to call out TMDE, no need for
  worker to determine equivalency, just pick any
  current meter from the SCAT code.
• NAVSEA 08 will no longer need to track GPETE
  obsolescence, NAVSEA 04 actively does this in
  TMDE index.
• Formal Communications All of our measurement
  requirements are now know by NAVSEA 04, including
  when SPETE is required. This should eliminate
  surprises at the Cal Lab.
• CMRS data sheets All measurement requirements
  are now documented for future use.

5
Big Picture Plan

• Step 1 Formulate plan and get NRHQ approval
• Step 2 Review and update source requirements as
  required.
• Step 3 Determine measure requirements, assign
  SCAT codes, and incorporate them into component
  technical manuals (CTM).

6
Conversion Status Step 1 Get NRHQ approval for
change.

• The long term plan to convert the NAVSEA 08
  process for determining meter equivalency to the
  NAVSEA 04 process was approved by NAVSEA letter
  Ser 08K/05-04118, dated 21 December 2005.

7
Conversion Status Step 2Update all source
requirement documents

• The following source document revisions were
  authorized by NAVSEA 08 on 13 December 2006.
• TM-1- Preparation of Technical Manuals for
  Special Purpose Mechanical and Electrical
  Equipment
• Provides guidance on how to incorporate SCAT
  codes into manuals.
• MIL-DTL-23200- Detail Specification, General
  Specification for Control and Instrumentation
  Equipment
• Removed Portable Test Equipment List 1A
• E-569368-DID-I- Data Item Description for
  Equipment Hardware Design Documentation
• Requires vendor to provide measurement
  requirements. If required, BPMI completes the
  CMRS data sheet.

8
Conversion Status Step 2

• New BPMI Operating Instruction (OI) EN112 Test,
  Measurement Diagnostic Equipment
• Provides relevant TMDE definitions
• Identifies how to complete a CMRS form
• Details the interface with NAVSEA 08 and NAVSEA
  04
• NAVSEA 0989-031-4000 Reactor Plant
  Instrumentation Control Equipment Maintenance
  Manual
• Section G/I 8 - Selection of Equivalent
  Electrical Meters, Recorders and Oscilloscopes
  updated to recognize use of SCAT codes.

9
Conversion Status Step 3

• Schedule
• Schedules are based by ship class and equipment
  suit installed (i.e. S8G Type 2, 688 Type 1 )
• Based on remaining service life, not all class
  manuals will be converted. (i.e. CVN65, NR-1,
  Analog equipment being replaced by Microprocessor
  equipment)

10
Conversion Status Step 3

• Conversion Outline
• Applicable system engineers completed part 1 of
  CMRS data sheets based on Component Technical
  Manual procedures. To aid NAVSEA 04, current
  model used was also listed.
• It was stressed NOT to base measurement
  requirements solely on existing model being used.
  
• Completed sheets are provided to NAVSEA 04 by
  BPMI. BPMI co-ordinates any questions from
  NAVSEA 04 to the applicable system engineer.

11
Conversion Status Step 3

• Conversion Outline
• Once completed, NAVSEA 04 provided completed CMRS
  data sheets (SCAT code assignment) to BPMI.
• SPETE (which may not have been previously
  identified to NAVSEA 04) is also being assigned a
  SCAT code to ensure proper support is identified.
• BPMI updates the component technical manual to
  use SCAT codes during next routine manual
  revision. Any measurement that does not meet a
  41 Test Accuracy Ratio requires NAVSEA 08
  approval prior to use.

12
Conversion Status Step 3

• First conversion (S8G - Type 2) process is in the
  final stages of CTM revisions.
• Remaining project schedules are being evaluated.
  Next project being worked is 688- Type 2.

13
Future Projects

• Contracts will be written to require the vendor
  to provide measurement requirements. BPMI will
  use this data to complete the CMRS data sheet.
• CVN78 contracts have been written using the new
  process.
• Type 2 equipment contracts for Virginia and
  Seawolf classes have also been written using the
  new process.

14
Summary

• Significant progress has been made to date for
  this effort.
• All parties have been participating in bi-weekly
  telecons to review status and address any issues.
• Having completed the first project, all parties
  are currently looking at lessons learned, and
  updating processes to make improvements.
