These objectives shall be achieved through facility design optimization, practical/realisti practical/realistic c management of possible hazards (with the knowledge of their causes and consequences) and the application of quantitative risk analysis (QRA) to quantify risks and demonstrate that the overall risk to personnel from the facility is within within accepted risk criteria. In addition, for fire f ire protection design, active fire protection/passive fire protection combined approach should be considered comprehensively. Generally, active fire protection will be applied for equipment, and passive fire protection will be applied for structure and support. In case thatapproach risk assessment determines another should be applied. or one approach is not appropriate, the protection by There are several type of fire fighting system to be provided in onshore facilities and they have the suitable roles for each stage of fire incident. -

Escalation of fire to other Active Fire Protection zones will not be taken into account since the fire is assumed to be contained in that Active Fire Protection zone only. Possible potential fire(s) within an Active Fire Protection zone shall be evaluated comprehensively to establish realistic and credible scenarios as design basis for the fire comprehensively protection systems.  Accordingly, the fire water system, fire mai main, n, firewater pumps, pumps, and firewater tanks, tanks, shall be designed as per the firewater demand that is based on one fire case in one Active Fire Protectio Prote ction n zone. zone.

2. 2.3 3

Acti Active ve Fi Firre Pr Prot otec ecti tion on Zone Zone (AFP AFP Zone) one)  An Active Fire Protection Protection Zone is defined defined as the area area separated from adjacent adjacent areas by barrier or distance, including bunding and drainage to prevent pool spread, where a fire is assumed to occur and can be reasonably reasonably expected expected to have its effects confined in that area alone. Consequently fire scenario scenario for fire system design is limited in one AFP Zone at a time. For the illustration illustration of the Active Fire Protection Zones, refer to L790-AF-PHI-0002, “Plant Zoning Philosophy”

2. 4

Minimal Manpower   The fire fighting f ighting system design shall include considerations considerations such as automatic actuation, and remote actuation from Central Control Building (CCB), to minimize fire-fighting manpower and reduce risk to personnel. The fire protection philosophy is such that emergency personn personnel el can carry out their duties without undue risk to them from the incident, in particular the effects of explosion, flash fire, and catastrophic escalation and vessel rupture. Where reliance is placed on manual emergency response, this shall be agreed with Client and only implemented where there is a realistic expectation expectation of response in terms of number of personnel, response time, equipment equipment deployment d eployment and effectiveness.

Hazards around the plant The active fire protective system for Ichthys onshore LNG facilities shall be properly p roperly designed designed to assure effective fire f ire fighting for the credible scenarios for each type of hypothetical hazards hazards described below. Principal hazardous materials contained in Ichthys onshore LNG facilities are methane, ethane, propane, butanes, hydrogen sulfide and sulfur. Pentane, hexane, and methyl di-ethyl amine (MDEA), dieselinoil, diesel lube oil, oil are handled. handl ed. Methane, ethane, ethaspillage ne, propane and butanes are handled gas form orhot liquid formalso (LPG, LNG). LPG or LNG spillag e will involve vapor cloud hazard or fire hazard (pool fire, spray fire), if ignited. Leaks of these materials in gas form will cause a torch fire immediately if ignited. Leak of these materials in liquid form will cause a spray fire if ignited. Hydrogen sulfide is a toxic, flammable and explosive gas and is very dangerous to human life. Pentane and hexane are principally handled in liquid form and they can be dealt with as flammable liquids (oil) from the point of view of fire hazard. MDEA has less flammabili f lammability ty and does not readily burn. Therefore, no special consideration is required for fire hazard.  A fire caused from LNG, LNG, LPG or gaseou gaseous s hydrocarbons hydrocarbons shall be extinguished extinguished only when when continuous leaks of hydrocarbon hydrocarbon are stopped. Equipment mainly handling handling flammable liquid shall be covered by water cooling such as fire water monitor or spray systems. systems. For detail, refer to L790L790-AF-LIS-0001, AF-LIS-0001, consolidated consolidated hazardous equipment list. There are also electrical hazards around electrical equipment, such as generator etc. For these hazards, specific measure, e.g. gaseous extinguishing system or the exclusive portable extinguishers shall be considered. considered.

2.8.1

Process Area (1 (1))

Gas Gas Rel Relea ease se Wi Witthout hout Fir Fire e Potential leaks from flammable gaseous hydrocarbon facilities may cause a jet stream. If a large amount of gas heavier than air leaks, the leaked gas may flow in a downwind direction and accumulate on the ground and may be detected by a fflamma lammable ble gas detector. When a gas leak is discovered by flammable gas detector, the affected process equipment will be shutdown, blocked-i blocked-in n and/or d depressuriz epressurized ed manually to control any further leakage.

Lique Liquefie fied d Gas Gas Rele Release ase Without Without Fire Fire When liquefied gas (LNG or LPG) is released into the atmosphere, some portion of the liquid will immediately vaporize, and some portion will remain in liquid form and will accumulate on the ground. The produced flammable vapour would easily travel in a downwind direction. For LNG/LPG spills, the spilled LNG/LPG should be collected in the relevant spill impounding basins. High expansion foam can be applied in order to control vaporization vaporization for spill impounding only for LNG. The spill impounding basin shall be designed so that its volumetric capacity will be at least equivalent to the largest leakag leakage e that can be discharged into the area during a 10-minute duration or the largest equipment inventory whichever is greater, in accordance with NFPA 59A and EN 1473.

for impounding basin, refer to L290-AH-REP-0001, Study report for LNG/LPG Spill Volume for Impoundment Impoundment Pond.  At the same time, the immediate immediate surrounding surrounding area of the spill s should hould be sprayed sprayed with water by manual actuation of fixed spray system(s), fixed and/or portable monitors and hydrant hose streams to disperse the vapour clouds in these areas while the area containing liquid spills shall not be sprayed with water, because it will accelerate vaporization. When designing the drainage system around process equipment in active ffire ire protection zone, consideration should be given to minimize the quantity of fire water that may flow to a spilled drainage area in the different zones. Low temperature spill detectors located at the LNG spill basin will automatically apply high expanded foam on the spilled liquid surface to control vaporization speed of spilled LNG. Refer to L830-AF-PHI-0001, L830-AF-PHI-0001, Fire and Gas detection philosop philosophy. hy. For LPG/Mixed Refrigerant (MR), high expansion foam system will not be provided. (3)

Gas fires should should not not be extinguishe extinguished d to avoid re-ignition and explosion. explosion. The method method of dealing dealing with with gas fires is via appropriate appropriate isolation isolation and blowdown of the process system. system. Refer to L290-AP-PHI-0002, L290-AP-PHI-0002, Emergency Shutdown Shutdown and Depressuring System Philosophy. Therefore, adequate water for cooling adjacent and affected equipment/structures around and/or within the fire shall be provided via automatic activation of fixed f ixed water spray system/oscillating monitors, manual activation of fixed/portable monitors and/or hydrant hydrant hose streams. streams. Jet streams resulting from possible leaks of flammable gaseous hydrocarbons hydrocarbons stored in pressurized vessels, when ignited, can produce jet fires. Jet fires can quickly cause damage to equipment, pipe and/or structures directly impinged with the fire. Therefore, this equipment supports and/or structures directly impinged with the flame must be cooled with solid water streams as quickly as possible from oscillating and/or portable monitors or hydrant hose streams.

Note that cooling by water spray application is not effective because the high velocity of the jet stream may deflect a water spray or fog pattern. The location of the occurrence of  jet fire and their direction direction cannot be also assumed assumed and fixed spray system for jet fire cannot be provided. Accordingly, only solid water stream from monitor or hose nozzle is effective for jet fire. Jet fire extinguishment shall only be commenced only after the leakage source has been cut-off. (4)

Pool Fire When liquid hydrocarbon, LNG/MR or LPG leaks, a pool is generated, and when ignited, will result in pool fire.

 A pool fire produces an intense h heat eat radiation and and damage structures structures and/or equipm equipment ent in that area and adjacent areas. Therefore, any equipment that is in or adjacent to possible pool fires shall immediately be cooled by water via fixed and/or and/or portable monitors monitors or hydrant hose streams or fixed water spray systems, if provided. In addition, Drainage shall be designed as far as possible to prevent pool fires under the equipment. Load-bearing supports for pipes/equipment, pipe racks and vessels within a possible pool fire, i.e. within a fire scenario envelope, should be fireproofed to withstand withstand the heat effects.

Equipment/structure cooling cooling by water application is essential to prevent them ffrom rom being damaged/failed, damaged/faile d, even if the water application onto the LNG/LPG liquid spill cannot be avoided and increase the flame intensity. Hydrocarbon pool fires, other than LNG, MR, or LPG spill, shall be extinguished by low expansion foam either via portable or fixed f ixed foam monitors/foam hose streams. However, low expansion foam shall not be used for LNG/MR/LPG pool fires as this will increase the fire intensity. If a fire happens in LNG spill basins, fire intensity shall be controlled by high expansion foam system automatically automatically activated by signals from spill detectors. For MR/LPG pool fires, no fire f ire extinguishment extinguishment should be applied, and the pool fire will be allowed to burn continuously until the fuel is exhausted. Therefore, it is important that the leakage source be immediately shut-off and depressurized to minimize the pool fire duration. High expansion foam is not normally applied applied for MR/LPG fires because application of such foam would sometimes extinguish MR/LPG fire that will result in a more dangerous situation because MR/LPG is heavier-than-air gas, and the vapor of MR/LPG will be accumulated beneath the foam blanket and have a risk of re-ignition and explosion.
