“FyreWrap Durablanket Marine” - A60 Steel Bulkhead (General)

Common issues

• Compression or settling of the fibrous insulation over time, reducing effective thickness at the fire division
• Sagging or gaps where retaining pins/washers have corroded or failed
• Moisture ingress degrading the insulation binder and reducing fire performance
• Mechanical damage from cargo handling or maintenance work carried out near the insulated bulkhead
• Unsealed or improperly fire-stopped penetrations (cables, pipes) added after original installation
• Missing or damaged protective covering/cladding exposing the insulation to physical damage

Inspection checklist

• Check retaining pins and washers are intact and insulation is not sagging away from the steel
• Spot-check insulation thickness against the approved A60 system drawing where accessible
• Verify all pipe/cable penetrations through the division are fire-stopped to the same rating
• Check for water staining or damage indicating leaks affecting the insulation
• Visual check of protective covering/cladding for damage or gaps
• Confirm any repairs since last survey are documented and match the original type-approved system
• Check for compression or voids at corners and stiffener crossings

Service intervals

Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.

Critical spares

• Matching insulation blanket material of the correct type and thickness
• Approved retaining pins and washers
• Approved facing/cladding material
• Approved fire-stopping material for penetrations

Safety

• Ceramic/mineral fiber insulation can cause skin and respiratory irritation during handling - use PPE per the manufacturer's safety data sheet during removal or repair
• Do not compress, staple, or penetrate the insulation in ways not shown on the approved installation drawing, as this can void the division's fire rating
• Hot work near uninsulated or damaged sections of the division requires a fire watch and permit

Class survey

Note: the listed product type ('Fire Hose') does not match this item - the product name and manufacturer indicate a ceramic-fiber insulation blanket system used to achieve an A60 fire division rating on a steel bulkhead, not a fire hose. Class checks that the installed division matches the approved fire test/type-approval drawing (blanket type, thickness, pin spacing, penetration seals); undocumented field repairs are a frequent survey and PSC finding.
