DESIGN BASIS
3.1
The fire fighting system shall be designed on the basis of only major fire with
a single fire risk area at a time.
3.2
No simultaneous occurrence of fire, either within a single fire area or in
multiple locations in the plant, shall be considered.
3.3
The fire areas shall be defined as areas which are bounded by the limits of a
credible fire escalation event. In order to have a useful subdivision of the fire
areas, the fire areas may be divided into fire zones. The fire zones in open
plant section.
The following area or facility is considered as one single fire risk zone.
1)
In the process area, all equipment located in an area separated to other
equipment by means of pipe rack, roads or distance of at 15m.
2)
In the tank storage area, the one tank is considered as one fire risk area.
3)
In the building area, the independent room enclosed by noncombustible
materials is considered as one fire risk area
Changes in Plot Plan layout during Detail Engineering must be checked
carefully if they are influencing the layout of the fire zones.
4.
FIRE WATER SUPPLY AND DISTRIBUTION SYSTEM
4.1
Fire Water Demand
The fire water demand shall be determined based on the largest single fire
water demand from the respective area requirements in the plant.
The estimated firewater demand shall be the sum of water required for fire
protection fixed systems(e.g. water spray system, sprinkler system) and
manual fire fighting equipment (e.g. fire monitor, hose stream) based on a
single major fire breaking out in one fire risk area at any one time over the
entirety of the site. The biggest firewater demand of one of the fire risk areas
shall be the total firewater demand.
For the purpose of estimating total firewater demand, followings shall be
applied:
y
Firewater demands for two (2) Fire monitors + two (2) Fire hydrants +
fixed water spray system.
For the purpose of estimating total firewater demand shall be 795 m3/hr. The
estimated fire water demand calculation is summarized in Attachment # 3

(2) One (1) Fire hydrant (2-1/2” hose line x 2): 114 m3/hr (1,900 lpm)
(3) Fixed water spray system: Application Rate of exposed surface
The fire water demand is estimated by considering several fire scenarios.
The biggest incident scenario would be the following:
The maximum firewater demand is estimated at 795 m3/hr for any single
major fire case on the ammonia process area. Based on preliminary
firewater estimates, the ammonia process area have been indicated as
producing the higher firewater demand during a single fire incident.
The maximum fire water requirement for the ammonia process area is
calculated base on a deluge water density of 20.4 lpm/m2 for synthesis gas
compressor surface area.
The largest fixed water spray 2 gas compressors
292.5 m3 /hr
fire water monitors,114 m3/hr each (1,900 lpm each)
