3. ACTIVE FIRE-FIGHTING PHILOSOPHY

3.1 GENERAL PRINCIPLES

It shall be first understood that extinguishing a main jet fire is not credible. The single possible

strategy in case of such a fire is to shut-off the source of fuel and to promptly evacuate all

personnel.

The fire-fighting philosophy shall be focused on the capability of :

Extinguishing small hydrocarbons fires at their early stage of development. This shall be

achieved manually, through portable or wheeled fire extinguishers.

Extinguishing pool fires limited to the retention basins or the dikes below equipment or tanks.

This shall be achieved manually, through mobile or fixed foam systems of low expansion.

Extinguishing automatically fires in the machinery enclosures through CO2 total flooding.

Extinguishing manually electrical fires by means of either portable and mobile extinguishers, or

fixed CO2 extinguishing system depending on the enclosure characteristics.

Extinguishing cellulosic fires and limiting smoke development in buildings with high occupancy.

The use of water as a cooling agent shall be understood to be a mitigation measure only.

3.2 SPECIFIC PLANT REQUIREMENTS

3.2.1 Plant arrangement

The Plant layout looks for two separate areas : one including all process facilities ( ISBL ) , the

other including the condensate storage facilities ( OSBL ).

Because these two areas are some 3 Km apart from each other, two separate fire-fighting systems

shall be provided, each one serving the dedicated area only.

The ISBL area looks for a wide ground levels differences so that fire water shall be supplied by

two independent pumping system : one serving the upper level section, the other serving the lower

level section.

The OSBL area is assumed to be like a flat area, so fire water will be supplied by a dedicated fire

water supply system.

3.2.2 Water sources

The system shall provide for two independent sources of water for fire service.

Primary Water SourceDesalinated water shall be used as primary source and be permanently stored to allow for system

uninterrupted operation for the required time.

Desalinated water shall be supplied to ISBL and OSBL storage directly from Phase 4&5 Unit 126

desalination facilities at 350 m3/h rate approx.

This capacity shall serve for tank filling and continuous make-up service.

A dedicated pipeline shall be provided from ISBL Phase 4&5 Unit 126 desalination facilities area to

supply the OSBL area.

Alternative Water Source

Sea water shall be used as an alternative source and be supplied at the design capacity as

required by any of the fire water system.

At ISBL area, Sea Water shall be directly supplied by Phase 4&5 Unit 125 sea water pumps.

At OSBL area, Sea Water shall be supplied by any source as available through the entire South

Pars Field ; investigation and selection for the the most practical sea water source shall be

performed during detailed engineering stage as well as study for adequate modification and

interconnecting as necessary.

following minimum figures :

120 m3/h for one mobile monitor plus 60 m3/h for fire hoses in process areas.

300 m3/h for mobile water/foam monitors in storage areas.

All the above systems, except the automatic extinguishing system on tank rim seal, require human

local operation.

For bund area, small surface bund area around loading / unloading line can be extinguished by

mobile means. Fixed foam protection system for full surface bund fire are not envisaged since

there is no credibility in extinguishing the fire due to very large area of bund. In case of large pool

fire in bund, the tank in bund on fire could be lost and the adjacent tank(s) will be protected by the

Water spray systems for cooling the shell of the tank on fire and adjacent tank(s) included in

the Fire Area (application rate: 15 lit/min/m of the whole outer shell circumference).

Mobile water/foam monitor(s).

All the above systems require human local operation.

For bund area, small surface bund area around loading / unloading area can be extinguished by

15.4 FIRE WATER S YSTEM DESIGN

The Onshore facilities Phases 4 & 5 are located in two separate sites : One site housing all

process facilities ( ISBL ) , the other housing the condensate storage facilities ( OSBL ).

The two sites are separated and each is far from the other, so the design of fire water supply

system shall require different approaches as follows.


31/57


Doc. N. RP 2017 999 1900 002 Rev. 6

Page 31 of 57


15.4.1 ISBL Area

The plant layout looks for some 48 m level difference between the fire water pumping station and

the highest plant area, this last being expected to require a very high water demand.

Due to this reason it appears not acceptable to provide one only pumping system serving all the

plant areas at the same time; because of the wide level range it would originate very high pressure

at lower areas, this last being an unacceptable condition from both technical and safety point of

view .

Considering the above and the need for having the Fire Water pumping station located in a safe

place ( far from major risks ), the selected approach is to provide two separate fire water systems,

each one serving plant sections at a elevation level range hydraulically acceptable.

Any system shall consist of three main fire pumps as well as two jockey pumps supplying a

distribution network located all around the reference plant areas.

Because of the differences in pressure design, any system shall operate as a stand alone system

without interface to the other system.

The two pumping sets shall take suction from a common storage tank provided with suitable

facilities for independent handling and isolation of any set.

The proposed arrangement looks for the following Units grouping :

Plant upper section : units at elevation between 70 and 90 m

Plant lower section : units at elevation between 38 and 56 m

In general the Fire Water Supply System shall be designed on the following general principles :

One only fire occurrence at any time; being the fire source located everywhere through the

reference plant area.

Simultaneous running of both Upper and Lower section fire pump sets at the same time for six

hours minimum time.

Normal power failure in case of fire

Emergency power availability in case of fire

Full independence from Firefighting facilities external to the Phase 4 & 5 Plant

Based on final estimation the ISBL Design Fire Water Demand is set as follows :

Plant upper section : 1010 m3/h

Plant lower section : 1237 m3/h
