Shipboard In ReviewRevisions based
on the expected trend for new construction programs to generate medium voltage (>1000 volts).
Updated requirements for jam nuts, lock wahsers and other fasteners, maximum compartment temperature requirements, fusing, thermal imaging windows
and other lessons-learned from

Switchgear
, Power, Shock-Mounted, Low Voltage, Naval
Shipboard New
- In ReviewCreated to establish standard construction, testing, and safety requirements for shock-mounted low voltage switchgear that will result in consistent vendor pricing from program to program.
Originally intended to use commercial specifications as a baseline and publish through a commercial governing body.
Considered
revising MIL-DTL-16036M to include requirements for shock-mounted low voltage switchgear.
Concluded
that
commercial
specs and 16063M were not readily adaptable for Navy shock-mounted requirements.

NAVSEAINST 9304.1E
“SHIPBOARD CABLE AND CABLEWAY INSPECTION AND REPORTING PROCEDURES”
Issue expected early April
Instruction describes the requirements for planning and performing shipboard cableway inspections and correcting identified cable and cableway hazards. It covers all cable types used in the fleet. NAVSEAINST 9304.1E includes
cable inspection criteria now includes CVNs (new)cable inspection criteria
Cable Deficiencies Categories revisedwill no longer allow approval of a CAT 1 DFSadds guidance for dead-ended and future use cablesadds modules on wiring techniques, terminators and a cableway print material guide to cable inspection training program
The new instruction is now consistent
with the
Joint Fleet Maintenance Manual
(JFMM)
and current cableway inspection practices.
