Fire Doors, Dampers & Structural Fire Protection
in China.

Structural fire protection inspection and repair

Passive fire protection contains smoke and heat so active systems and escape arrangements can work. A door that does not close, a seized ventilation damper, damaged A-class insulation, or an unapproved cable penetration can compromise an entire fire boundary. This service covers systematic inspection, operational testing, defect mapping, repair coordination, and evidence for class, flag, or Port State Control follow-up.

Regulatory context

SOLAS chapter II-2, the Fire Safety Systems Code, the vessel’s approved fire-control plan, and type-approval conditions define the arrangement. Fire doors and dampers are frequent inspection items because everyday use, corrosion, modifications, and poor hold-open practices can defeat them. Repairs must preserve the approved rating and construction. Materials, seals, insulation systems, and penetration products should be approved for the exact boundary and installed according to their approval documentation.

Typical scope

• Inventory and function testing of self-closing fire doors, releases, indicators, latches, hinges, seals, and closing speed
• Operation of local and remote fire dampers, verification of position indication, access, marking, and freedom of movement
• Inspection of A- and B-class divisions, ceilings, linings, insulation, draught stops, and structural continuity
• Review of cable, pipe, duct, and ventilation penetrations for damage or unauthorised materials
• Photographic defect register, repair method, material certificates, completed-work evidence, and retest report

Preparing a closure attendance

Send the vessel, port, fire-control and insulation plans, deficiency or survey report, affected item numbers and locations, photographs, required completion date, and witnessing requirements. Identify asbestos controls, hot-work restrictions, accommodation access, and whether approved spare doors, actuators, seals, insulation, or penetration kits are onboard. Final closure remains with the issuing authority; clear before-and-after evidence and traceable materials help that review proceed efficiently.
