Flare Tower Structure
System Requirements: Jet Fire 60 mins
The Flare Tower Structure had been protected against a possible jet fire scenario with an epoxy type intumescent fire protection system. However, due to increased production resulting in higher flare temperatures, the intumescent fire protection had hardened and cracked over the years thus allowing water to penetrate beneath the fire protection system creating a high risk of corrosion under insulation. A decision was taken by the client to remove this system, refurbish the Flare Tower structure and apply a light weight removable fire protection system.
In February 2012, Gardyon’s ISO-JF180 Jet Fire Flexible Jacket System was specially chosen by the client for this application due to its high resistance against jet fires and also its ability to withstand the long term harsh offshore environment.
The Jacket System was designed to withstand a 60 minute jet fire and included all secondary steel work and major supports from ground level up to an elevation of 37 metres.
Pipings, Valves, Flanges, Pipe Supports, etc.
System Requirements: Jet Fire 60 mins + Static Blast Overpressure of 0.56 barg + Dynamic Blast Pressure of 0.3 barg
