DDS-078-1
  • DDG 1000 has a deckhouse which will be
    constructed from fiber reinforced plastic
    (Composite) materials.
  • Fire performance of composite materials is
    covered under DDS-078-1, Composite materials,
    Surface ships, Topside structural and other
    topside applications Fire performance
    requirements
  • Contains fire performance requirements for
    Structural composites such as flame spread, smoke
    generation, fire growth, fire resistance, and
    structural integrity.
  • Contains fire performance requirements for non
    structural composite items such as weather deck
    gratings, louvers, ducting, valves, etc.
  • Rev 1 is under review, and includes
  • GRP piping requirements
  • Revision of structural integrity section for
    composite structures.
  • Revision of smoke index and carbon monoxide
    limits.
  • Addition of the Table which lists Navy approved
    Composite N-Class divisions.

MIL-STD-X129
  • Draft MIL-STD-X129, Fire Resistance of U.S.
    Naval Ships
  • Draft MIL-STD-X129 provides the detailed test
    procedure and acceptance criteria for the fire
    resistance (i.e., prevention of fire spread
    through a boundary) for divisions (e.g.,
    bulkheads and overheads/decks) and their
    penetrations on U.S. Navy ships.
  • Institutes two Classes of Fire Resistant
    Divisions
  • N-Class N-Class Divisions are those divisions
    (bulkheads and decks) that are designed to
    protect against structural failure and prevent
    the passage of fire and smoke when exposed to a
    rapid rise hydrocarbon fire exposure (Class B).
    The minimum fire test duration is 30 minutes. In
    addition, N-Class divisions are designed to
    prevent excessive temperature rise for a
    designated test period such as 30 minutes (N-30).
  • AN-Class AN-Class Divisions are those divisions
    (bulkheads and decks) that are designed to
    protect against structural failure and prevent
    the passage of fire and smoke when exposed to an
    IMO A. 754(18) fire exposure (Class A). For all
    AN-Class divisions, including those with
    penetrations, the test duration is a minimum of
    60 minutes. In addition, AN-Class divisions are
    designed to prevent excessive temperature rise
    for a designated test period such as 60 minutes
    (AN-60).

MIL-STD-X129
  • Fire Resistant Divisions
  • N-30 Unrestricted Application means that
    insulation is installed either on both sides or
    on the non fire side to meet the requirements for
    temperature rise during the fire test.
  • N-30 Restricted Application means that
    insulation is installed on the side from where
    fire threat is anticipated. The division is
    classified as Fire Resistant only in one
    direction, from the fire side where the
    insulation is placed.
  • N-0 Steel is inherently (without insulation) N-0
    when used in thickness greater than 4.5 mm with
    suitable scantlings. N-0 means it prevents
    structural collapse and passage of flame and
    smoke.
  • Aluminum melts when exposed to Class A or B fire,
    and hence requires insulation for any kind of
    fire resistance rating.

MIL-STD-1623E
  • MIL-STD-1623 E, Fire Performance Requirements and
    Approved Specifications for Interior Finish
    Materials and Furnishings
  • MIL-STD-1623E is a revision of MIL-STD-1623D and
    updates fire performance criteria for materials
    in
  • bulkhead sheathing
  • overhead sheathing
  • Furniture
  • draperies and curtains
  • deck coverings
  • Insulation and
  • bedding applications.

Composite BerthInterim Fire Test Procedure
  • INTERIM FULL SCALE FIRE TEST METHOD FOR COMPOSITE
    SHIPBOARD BUNKS
  • Ser 05P4/110 October 2006
  • Fire Source 50 kW for 5 minutes followed by 100
    kW for 10 minutes
  • Similar to NAVSEA 05Z6 PD 5-04A

19
Bonded Fasteners
  • The U.S. Navy is considering attaching furniture
    items to studs that are adhesively bonded to the
    ship boundaries as an alternative to welded
    studs for installing specific USS WASP and LPD-19
    berths and lockers.
  • It is believed that this technology could
    provide significant cost/time savings benefits
    for ship overhauls and repairs.
  • This technology could also provide deployed ships
    with the capability to perform repairs or
    installations that are currently difficult or
    impossible to perform with the current welded
    studs which require fire watch for hot works.
  • Ser 05P4/xxx (Under review) provides the fire
    performance requirements of adhesively bonded
    studs used to mount furniture items to ship
    boundaries. Ship boundaries may consist of steel,
    aluminum, or composites.
  • Adhesively bonded studs may be permitted in
    compartments outfitted with sprinklers. In
    addition, the boundary containing the bonded
    studs must have at least an N-30 fire resistance
    rating or the adjacent compartments must be
    outfitted with sprinklers.
