Safety within offshore environments demands specialised solutions, especially in critical areas like offshore lifts. These lifts, often used to transport crew, equipment, and supplies between decks, present unique fire safety challenges due to their enclosed nature and connection between multiple fire zones. The integration of SOLAS A60 fire-rated doors into offshore lifts plays a pivotal role in maintaining vessel safety and ensuring compliance with stringent international maritime safety standards.
The Role of A60 Fire-Rated Doors
Offshore lifts operate in dynamic, high-risk environments where the potential for fire outbreaks exists in spaces like engine rooms, machinery spaces, or cargo holds. A60 fire-rated doors are essential for:
Fire Containment
Offshore lifts often span multiple decks, creating a vertical passageway through the vessel’s fire zones. Installing A60 fire-rated doors at lift entry points ensures that fire and smoke cannot travel through these openings, maintaining compartmentalisation.
Protecting Critical Evacuation Pathways
In an emergency, lifts may act as vital pathways for crew evacuation or the transport of emergency equipment. A60 doors ensure that these pathways remain shielded from fire and smoke for at least 60 minutes, allowing time for safe evacuation or emergency response.
Minimising Fire Escalation Risks
By acting as robust fire barriers, A60 doors help isolate fire incidents in high-risk areas, such as cargo lifts located near flammable materials or machinery spaces.

Key Features of A60 Fire-Rated Doors in Offshore Lifts
High-Temperature Resistance
A60 doors can withstand temperatures exceeding 593°C for 60 minutes, critical for maintaining the structural integrity of lift compartments in a fire.
Custom Fit for Lift Shafts
These doors are tailored to fit the unique dimensions and operational requirements of offshore lifts, ensuring integration without compromising safety or functionality.
Automatic Closing Mechanisms
Many A60 doors used in lift systems are equipped with automatic closing features triggered by fire detection systems. This prevents the spread of fire or smoke when the lift is inactive or during emergencies.
Durable Construction
HML build their fire-rated doors with steel or other heat-resistant metals and insulated cores made of mineral wool or ceramic fibres; these doors resist deformation, maintain sealing, and block heat transfer.
Smoke Seals and Tight Gaskets
These features ensure that smoke does not seep through, safeguarding air quality and visibility within connected areas.

Applications of A60 Fire-Rated Doors
Crew Lifts
Used for crew movement between living quarters and operational areas, these lifts benefit from A60 doors by ensuring safe passage and preventing fire hazards from escalating between decks.
Cargo Lifts
Frequently located near high-risk zones like cargo holds or machinery spaces, A60 doors prevent fires from spreading to or from lift shafts, safeguarding essential supplies and the vessel’s structural integrity.
Why A60 Fire-Rated Doors are Essential for Offshore Lifts
Compliance with SOLAS Standards
Offshore lifts are subject to strict safety regulations. A60 doors ensure full compliance with SOLAS fire safety requirements, which are critical for vessel certification and operational fire safety strategy.
Improved Fire Safety
By containing fires and preventing smoke ingress, A60 doors safeguard both the lift’s functionality and the vessel’s overall fire safety strategy.
Durability and Reliability
Designed to endure harsh marine environments, these doors provide long-lasting protection in offshore lifts, reducing maintenance demands and operational risks.
Incorporating SOLAS A60 fire-rated doors into offshore lifts is an essential safety measure that enhances fire containment, protects crews and cargo, and ensures compliance with international maritime safety standards. HML ensure to include these SOLAS A60 fire-rated doors in their offshore lifts creating a fire-resilient offshore environment, safeguarding lives, and preserving vessel integrity.
