B-15 Class Bulkhead, type "K-600 panel system"

Common issues

• Panel joint or insulation degradation from moisture ingress or mechanical damage, compromising fire rating
• Unsealed or poorly re-sealed penetrations (cables, pipes) added through the division after the original installation
• Corrosion of steel core panels or support frames at deck edges and bilge-adjacent areas
• Loose or missing fasteners at panel seams reducing structural integrity of the division
• Coating/paint damage exposing insulation core to moisture
• Fire door or hatch seals degrading where they interface with the panel system
• Unauthorised cutting or drilling through the division during later outfitting or repair work

Inspection checklist

• Visual inspection for dents, holes, or other physical damage to panel surfaces
• Check all cable/pipe penetrations through the division are properly fire-stopped
• Verify panel joints and seams are intact and sealed
• Check for corrosion at the panel base/deck interface
• Confirm no unauthorised openings or modifications since the last survey
• Verify adjacent fire doors close and seal correctly
• Cross-check the installed division configuration against the approved fire control plan

Service intervals

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

Critical spares

• Replacement panel sections matching the approved type and thickness
• Fire-rated penetration seals/collars
• Approved panel joint sealant
• Fasteners matching the original specification
• Approved fire-rated touch-up coating

Safety

• A compromised fire division allows fire and smoke to spread between spaces - any breach must be made good and reported without delay
• Do not cut, drill, or otherwise penetrate the panel without an approved method - this can void the B-class fire rating
• Insulation core materials may present a handling hazard if damaged or disturbed - follow the safety data sheet for the panel core material

Class survey

Note on source data: the catalogued 'typ' field ('CO2 Fixed System') does not match this product. The certificate (UK MCA 80180/A0) and description identify a B-15 class fire division bulkhead panel system ('K-600 panel system') - a passive fire protection product, not an active CO2 extinguishing system. The content above addresses the actual product. 'B' class divisions are periodically verified against the approved fire control plan at each survey; any penetration, modification, or damage since the last survey must be documented and reinstated to the approved fire rating before certification is confirmed.

Estimated lifetime: Passive fire division panels are generally rated for the vessel's structural life with no fixed renewal interval; renewal is damage- or condition-driven rather than time- or hours-based.
