Design and thickness of Pyroclad X1 for fire protection

of divisions and supporting structure for Sao Vang

Definitions of fire rated divisions

There are some misconception over the requirements of a fire rated division (bulkhead), what he requirements of the construction are and what the fire protection coating is required to achieve

We refer to the design guidelines issued by DNVGL and HSE in the UK explaining what the requirements are (both documents available on request from Carboline)

There are two separate requirements, ‘insulation’ period is designated by the number but stability/structural integrity is independent of the number Regardless of the number the division and all its components must be maintained for 120min Practically this means that the supporting structure must be maintained with a 2-hour rating to 400oC This applies whether the fire source is Hydrocarbon or jet fire

PFP arrangement for fire divisions constructed along Truss 2 and Truss 5

TRUSS 2 Truss 2 shall be protected to a rating of H-0 This shall require 6.5mm of Pyroclad X1 incorporating high temperature reinforcement

Should jet fire protection be required then in accordance with the DNV certification, the thickness shall again

be 6.5mm incorporating high temperature reinforcement

TRUSS 5 Truss 5 shall be protected to a rating of H-60 This shall require 11.6 mm of Pyroclad X1 incorporating high temperature reinforcement

be 11.6 mm incorporating high temperature reinforcement

FIRE WALL - UNDER CELLER DECK Fire Wall shall be protected to a rating of H-0 This shall require 6.5mm of Pyroclad X1 incorporating high temperature reinforcement

be 6.5mm incorporating high temperature reinforcement
