Understanding A60 Fire Rating Standard and A60 Fireproof Materials for Offshore Containers

In order to fully enable offshore containers to fulfill various functions such as transporting perishable goods, providing living quarters, and accommodating workspaces, it becomes essential to undertake modifications that adhere to the container's thermal insulation and fire protection prerequisites. Typically, the containers offered by TLS are designed to meet the A60 standard, ensuring compliance with stringent safety regulations.

​Key Specifications for A60 Classification Society Standard:

1. Construction from steel or comparable materials, with a precise thickness of 4.5±0.5mm.
2. Strategic integration of suitable anti-flexion reinforcement, maintaining an aggregate spacing of approximately 600mm.
3. ​Fabrication from approved non-combustible materials, guaranteeing that the average temperature rise on the container's backside remains below 140℃ within a 60-minute span. Additionally, no single point on the rear surface should experience a temperature surge surpassing 180℃.

Characteristics of A60 Fireproof Materials: The chosen fireproof material should exhibit both rigidity and the ability to withstand fire for a minimum of 1 hour, all while preserving its structural integrity to thwart the passage of smoke and flames.

Rock wool and ceramic fiber wool stand out as two distinct alternatives for insulation materials in A60 fire protection applications. However, it is imperative that both materials receive official endorsement from the pertinent classification society to ensure adherence to safety standards and regulations.
