My Aim…..

Part 1 – Technical Background

The purpose of applying fireproofing is to provide temporary

protection until such time when fire fighting systems and loss control measures may be employed.

Loss control systems measures may include:

• Depressurization of vessels

• De-inventory of vessels

• Isolating fuel flow/limiting fuel availability shutting down units

• Actuating suppression/exposure

• Active cooling systems

BS EN ISO 13702: 1999, Petroleum and Natural Gas

Industries – Control and mitigation of fires and

explosions on offshore production installations –

Requirements and guidelines

API RP 14C - Safety Analysis for Production

Platforms

Specifies the requirements for the analysis, design, installation and testing of surface safety systems for offshore production platforms.

• Valve will be limited to a maximum surface temperature of

200°C for the duration of a 60 minute jet fire.

• Actuator will be limited to a maximum surface temperature of

100°C for the duration of a 60 minute jet fire.

• The protection will be provided up to and including the

conductor hang-off flange and seal arrangements.

• BS EN ISO 13702 indicates that a typical critical temperature for structural steel is 400°C.

• PFP systems shall resist a blast overpressure of 800mbar and provide the full specified fire performance after the blast.

Typical Design Requirements – Offshore

• The liquefied petroleum gases exist as gases at normal temperatures and pressures but can be liquefied under moderate pressure.

• If the pressure is subsequently released, the LPG again becomes gaseous. If an LPG vessel is involved in a fire, it may overheat and rupture violently giving an intensely hot fireball and may project pieces of the vessel over considerable distances.

• Such a rupture is commonly termed a Boiling Liquid Expanding Vapour Explosion (BLEVE)

Fire tests are performed on fireproofing materials to measure the level of

Protection provided by a particular fireproofing system (including material,

thickness, application method, etc.).

The fireproofing material aimed at protecting steel structures and supports from reaching 538 C for a period of 3 hours based on a fire exposure as defined by UL 1709.

Underwriters Laboratories has developed a test protocol to simulate hydrocarbon fire exposures. This test protocol is UL 1709 and is intended to approximate fire exposures that may be expected in a process plant.

Jet Fire Testing - ContraFlex®

Part 2 – Passive Fire Protection Systems

• An intumescent is a substance which undergoes a chemical reactions as a result of heat exposure, thus increasing in volume, and decreasing in density

Stage 1

• HEAT Source > React to heat > chemical reaction will start at around 65-80°C.

Stage 2

• Reaction > Material turns soft > emits gases and intumesce & expand into carbonaceous char

Stage 3

• Protection /Insulation > The char provide insulation that restrict the rate of temp rise of the steel. Char has to resist jet fire erosion when exposed to JF.

ContraFlame® is a multifunctional composite system based on

unique phenolic syntactic foam and phenolic glass reinforced

laminate.
