SUBMARINE SAFETY(SUBSAFE) PROGRAM
  • NAVSEA 0924-062-0010
  • Revision C

Approved for Public Release
4
SUBSAFE Requirements
  • Current requirements for the SUBSAFE Program are
    invoked in the Submarine Safety (SUBSAFE)
    Certification Manual, NAVSEA 0924-062-0010,
    Revision C.

Approved for Public Release

SUBSAFE Requirements
  • The SUBSAFE Program provides a maximum reasonable
    assurance of the integrity of submarine design,
    systems and materials via Design Review,
    Shipboard System Testing and Objective Quality
    Evidence (OQE) that all materials and components
    meet drawing and specification requirements.

Approved for Public Release
6
Objective Quality Evidence (OQE)
  • OQE is a statement of fact, either quantitative
    or qualitative, pertaining to the quality of a
    product or service based on observations,
    measurements, or tests that can be verified.

Identification of SUBSAFE Items
  • SUBSAFE Certification requirements are
    incorporated into Electric Boat Purchase Orders.
  • Identification of SUBSAFE material on the
    Electric Boat Purchase Order is by way of the EB
    REF ONLY SMC CAT field of the part description.
  • A 1 in this field signifies that the part is a
    SUBSAFE or Hull Integrity (HI) certification
    item.

SUBSAFE Requirements
  • SUBSAFE Certification is accomplished by the
    Shipbuilder after installation of material or
    components onto the ship. Certification uses the
    OQE provided by the supplier which is then
    entered into the Electric Boat Material Quality
    System (MQS), after acceptance of the material by
    Electric Boat Supplier Quality Assurance.

SUBSAFE Certification/Inspection Attributes
  • Electric Boat certification/inspection attributes
    invoked in the Purchase Order include the
    following
  • Verification of Material (Chemical and Mechanical
    Test results along with all Metallurgical Tests
    required by the applicable Military Specification
    of Drawing).
  • NDT required by the applicable specification or
    drawing.
  • Hydrostatic Testing required by specification or
    drawing.

Approved for Public Release
11
SUBSAFE Effects
  • Production or Operation Testing required by
    specification or drawing.
  • Torque certification for installed fasteners,
    when required by the drawing and specified in the
    Purchase Order.
  • Traceability of all Level I or SUBSAFE parts for
    the raw materials used.
  • Inspection of the hardware includes a complete
    verification of all visible traceability
    markings.
  • Inspection of the hardware also confirms
    compliance dimensional attributes required by the
    drawing.

Approved for Public Release
12
SUBSAFE Affects
  • Visual inspection of the hardware is also
    performed to ensure compliance with all visual
    and surface finish requirements.
  • All Welding, NDT and Testing (when required)
    Procedures are verified to be previously approved
    by Electric Boat on a Vendor Procedure Approval
    Request (VPAR) Form.

Approved for Public Release
13
SUBSAFE Certification Requirements for Suppliers
  • Obtain and Review Raw Material Chemical and
    Mechanical Test Reports.
  • Maintain Traceability from hardware to the Test
    Reports through all phases of processing and
    manufacture.
  • Perform all required NDT and provide Test Reports
    of the NDT.
  • Insure that all Special Processes (NDT, Welding,
    etc.) has been accomplished in accordance with
    Electric Boat approved procedures.
  • Insure welding is accomplished in accordance with
    weld procedures and Drawing requirements and
    provide all weld records, as required by the
    process specification.

Approved for Public Release
14
SUBSAFE Certification Requirements for Suppliers
  • Perform all Testing required by the
    Specification, Drawing and Purchase Order and
    provide Test Reports for the Testing.
  • Insure that all documentation meets the
    requirements of Electric Boat Specification 2678
    H, Appendix A.
  • Assemble the Documentation Package, including an
    Assembly Record, when required.
  • Visually and Dimensionally inspect hardware to
    verify compliance with Specification, Drawing and
    Purchase Order requirements.
  • Insure all Traceability Marking is on the
    hardware and is legible.
  • Insure adequate protection is provided during
    shipment and all shipping containers are properly
    identified.

15
Typical Certification Errors Identified During
NAVSEA Audits
  • Incorrect traceability data entered on the OQE.
  • Incorrect VPAR referenced for NDT or Welding
    Procedure used.
  • Torque Record indicates an incorrect torque or
    incorrect lubricant was used.
  • Raw material is in an incorrect heat treatment
    condition.

Who is Responsible for Submarine Safety?
  • Submarine Safety is the responsibility of all
    parties involved, from the manufacturer of the
    raw material, through installation and test
    onboard a nuclear submarine. The lives of the US
    Navy sailors depend upon compliance to the strict
    guidelines of the Submarine Safety (SUBSAFE)
    Program.
