This webinar will enable the participant to understand:
Why is it necessary to fireproof steel
Different types of fire protection for offshore structures
How Passive Fire Protection (PFP) works
Advantages of epoxy intumescent PFP
Offshore fire environments & testing requirements
Certification requirements for offshore applications
Factors that affect PFP thickness
Service environments for epoxy PFP materials
Applications methods & equipment
Primer and topcoat requirements
To protect assets
To prevent structural
failure
Maintain path of
egress
Save lives
Steel loses load carrying
capacity as the core
temperature increases
Steel begins to deform at
427 °C (800 °F)
PFP extends the time it takes
to reach the failure point
Limiting temperature is
project specific 200°C - 600°C
(392°F - 1112°F)
Most projects require 400°C
(752°F) limiting temperature

Passive
• Mechanical means of fire suppression that is activated
during a fire
• Deluge Systems
• Sprinkler Systems
• Halogen Extinguishers
• Foam Systems
• Coating or insulation applied to steel which insulates
substrate during a fire
• Concrete
• Cementitious Fireproofing
• Epoxy Intumescent
• Epoxy Intumescent Castings
• Insulative Fireproof Jacketing

Explosion resistant
Low maintenance
Long service life
When exposed to fire,
intumesces or “swells” up to 10
times original thickness
producing a heat blocking “char”
Applied like a paint in multiple
passes (5 mm/coat)
Durable finish that can be
topcoated
Passive coating under normal
conditions
Reaction insulates steel for a
given amount of time

Simulates pool of burning hydrocarbon fuel:
-IS0 834 / BS 476 Part 20-21 Appendix D (offshore)
-UL 1709 (onshore)
Tested For:
- I-Sections
- Tubular Sections
- Divisions(Bulkheads/Decks)
Simulates pressurized burning gas:
- IS0 22899-1
Tested For:
- I-Sections
- Tubular Sections
- Divisions(Bulkheads/Decks)
Additional material added to hydrocarbon
thickness to withstand the erosive effects
of a jet fire.
Erosion factors are generated by
comparing the results of the hydrocarbon
and jet fire testing at specific steel size
The jet fire erosion factor varies
dependant on steel type and fire duration

1. Hydrocarbon Pool Fire
- IS0 834 / BS 476 Part 20-21 Appendix D
- 30 minute – 180 minute
2. Hydrocarbon Jet Fire
- ISO 22899-1
- 15 minute – 120 minute
3. Hydrocarbon Jet Fire and
Hydrocarbon Pool Fire
Combination
- Any combo of time intervals
Efficiency of the material
Steel size
The more mass a steel section has,
the less PFP thickness it requires
The higher the critical limiting
temperature, the less thickness is
required
The longer the fire durations
require more thickness
Jet fire ratings require jet fire
erosion factor to be added to
hydrocarbon thickness

Reverse-A-Clean Tips
Epoxy PFP materials require mesh reinforcement for
hydrocarbon and jet fire applications
Typically installed at nominal midpoint
Mesh placement and overlap distance depends on
configuration of steel and fire exposure type.
Typical overlaps:
Hydrocarbon - 2” (50 mm)
Jet Fire - 6” (150 mm)
Only use manufacturer
approved primers and
topcoats
All Epoxy PFP must be
applied over compatible
primers
Primer system thickness
range should be 3-5 mils
(75-125 microns) per SSPCPA2
PFP systems are topcoated
with epoxy or polyurethane
finish coats
When selecting an epoxy PFP, verify the following:
Certification required / testing
Fire rating
Size and configuration of steel member
Wide flange, hollow section, bulkhead,
deck
Primer and topcoat compatibility
Application parameters
