NAVSEA.05Z Electrical Systems Technical Update - NSRP Initiatives and Priorities

Slide Note

Update on NAVSEA.05Z electrical systems technical initiatives and priorities, including standards and specifications projects supported by NSRP. Highlights key high-priority items related to circuit breaker obsolescence, cable supply shortages, and product qualification testing. Discusses fire-resistant qualification test requirements for cable transits and sealants, with a focus on MIL-DTL-24705B and MIL-I-3064. Emphasizes the need for funding to update specifications and resolve test plan approval issues to address product supply chain challenges.

NAVSEA 05Z3 Electrical Systems Technical Update Presented at the National Shipbuilding Research Program Electrical Technologies Panel Meeting August 10, 2022 Christopher Nemarich Engineering Manager Electrical Systems Ships SEA 05Z33 NAVAL SEA SYSTEMS COMMAND DISTRIBUTION STATEMENT A. Approved for public release. Distribution is unlimited.

NAVSEA 05Z Update to NSRP NAVSEA 05Z3 Initiatives and Priorities Summary of Standards and Specifications Projects NSRP Electrical Technologies Projects Supported DISTRIBUTION STATEMENT A. Approved for public release. Distribution is unlimited.

NAVSEA 05Z Update to NSRP NAVSEA 05Z High Priority Items SEA 05Z is working with NSWC PD on numerous issues related to Circuit Breaker Obsolesce and Qualification Testing Requirements Shortages of available MIL-DTL-24643 and MIL-DTL-24640 Electrical Cable Supply Chain and Qualification and Requalification Issues of MIL-DTL- 24705B MCTs andMIL- I-3064 Plastic Sealer Backlog of over-age specifications / standards / technical manuals and drawings Widespread qualified product obsolescence and vendor unwillingness to continue product qualification testing for RSL lighting components and instrumentation pressure transducers, salinity measurement and panel meters Supporting FFG 62 design reviews DISTRIBUTION STATEMENT A. Approved for public release. Distribution is unlimited.

NAVSEA 05Z Update to NSRP Multi Cable Transits and Sealants Fire Resistant Qualification Test Requirements for MIL-DTL-24705B Penetrators, Multiple Cable, Electric Cable (MCTs) 24705/1, 24705/3 and 24705 /4 MIL- I-3064 Insulation Electrical Plastic Sealer Bothrequire new test requirements for both the qualification and retention testing. Fire stop test requirements of MIL-STD-3020 Appendix D. Cable Transit Test Configuration and Appendix F have been invoked. Funding is needed to update the specifications. Shock Testing is required prior to Fire Resistance Test for QPL products to requalify. This change impacts QPL Approval for Existing and New Cable Transits, Sealing Systems and Sealants. Multiple TWH Stakeholder concurrence is required and has been obtained. Warfare Center review of both Qualification and Retention Test Requirements and the Submitted Vendor Test Plans is needed. NAVSEA is working to resolve the test plan review approval issues to get comments to Vendors and allow test plan to relieve product supply chain issues and new qualification of the NSRP developed MCTs and Sealing Systems. DISTRIBUTION STATEMENT A. Approved for public release. Distribution is unlimited.
