1. PROJECT OVERVIEW
A simplified schematic overview of the project is given in Figs 1.1 below. Fig 1.1 shows the
overall requirement of the CAFC project. Fig 1.2 shows the location of the CAFC project
within Algeria whilst Fig 1.3 gives more detail on the field development within Block 405b.
CAFC oil and gas processing facility will be built adjacent to the MLE CPF. Export lines are
sized to cater for both MLE and the Central Area Field Complex (CAFC).
Fig 1.1 CAFC Project Simplified Overview
1.1 CAFC DEVELOPMENT SUMMARY
The CAFC development concept consists of a field gathering system and 41 oil wells to be
connected to CAFC plant, central processing facility and necessary support infrastructure.
- The CAFC Oil wells (TAGI, F6-1 and F6-2 SWP) will be connected to the CAFC oil
slug catchers through gathering systems dedicated to TAGI reservoir and to F6 Oil.
The total number of wells is 51 divided in 41 oil producer (17 TAGI, 9 F6-2 and 15 F6-
1), 4 water injectors (TAGI), 3 gas injectors (TAGI) and 3 water producers. The
associated gas from F6-1 and F6-2 should be sent to MLE plant for final treatment,
while TAGI associated gas has to be re-injected till the gas cap blow down, expected
in 10 years.

- The CPF shall process part of the associated gas relevant to the gas injection and the
Oil products. CAFC CPF will be provided with its own flares and off-spec oil tank.
- The gas injection system is to re-inject gas into TAGI reservoir.
- The water injection system is to re-inject the produced and Barremian water into TAGI
reservoir.
- Infrastructure includes:
o Construction Camp
o Black top & Gypsum roads and access roads
1.2 CONCEPT
The general concept for development scheme consists on developing CAFC project
comprising following facilities:
Wells production / infields manifolds/ production and distribution
gathering system
Central Processing Oil Facility, associated utilities where
applicable and common installations
Gas injection & Water Injection
Infrastructures: road network and construction camp
The design and construction of CAFC project for common utilities installations will be
optimised in synergies with MLE plant.
A site topographical and geotechnical surveys should be carried out during the EPC activities
in order to acquire information regarding the physical characteristics of soil, assess the site
situation and planning civil works to be carried out.
Site preparation for CAFC facilities is executed by Contracting Authority and handed over to
the selected Contractor.
An Environmental, Social and Health Impact Assessment (ESHIA) study has been carried by
a third party contractor and submitted to local authorities. EPC Contractor shall comply with
the requirements of the MLE & CAFC ESHIA studies that will be provided.
The CAFC project is part of a two phase development scheme:
The initial phase shall consist of installing the CAFC wellsites and
Oil gathering system, and developing the CAFC CPF along with
its infrastructure.
A inlet gas booster compression is foreseen for 2
nd
phase, but not
included in the present SoW It is expected that the MLE booster
compressor required for MLE CPF after approximately year 5 will
also be used for CAFC
The second phase which is excluded from the Work is GAS
Blowdown phase.

1.3 COMMON FACILITIES INSTALLED AT MLE
The MLE NGL plant allowed space for future processing of the Central Area Facilities
Complex (CAFC) fields.
a. Common Installation for Combined Facilities
Process
o Oil Storage for combined MLE and CAFC production is foreseen in MLE Plant.
o Booster and Export Oil Pumps
- MLE Project designed pumps for CAFC and MLE combined but installed
pumps for MLE Production ONLY. Remaining pumps to be installed
within CAFC project. CAFC RAM study to confirm CAFC plant
availability specification is met with the required pumps configuration.
o Oil Fiscal Metering
- MLE Installed a larger fiscal meters for all products with required
turndown. No furthers fiscal meters are required for CAFC, only the new
technical meter as described in the FEED SoW.
Condensate Production coming from CAFC Gas Treatment could be connected to
MLE Liquid Processing
Off gas
The compressed off-gas for F6 gas only coming from the oil treatment section
will be dehydrated and re-injected along TAGI gas released from the slug
catcher. A connection to MLE plant is foreseen to be used in case of an
emergency.
Utilities
o MLE Plant designed and installed sufficient size of the following utilities for CAFC
rates:
- Fuel gas
- Diesel fuel
- Utility Water
- potable water
- de-mineralized water
- F&G
- instrument air
- plant air

- main power distribution
Instrumentation & Control/Tele
The control room to be used will be in the same building of MLE project. MLE
and CAFC projects shall be independent in terms of systems (DCS, SCADA,
ESD/F&G, etc.) to be used. However, it shall be necessary to exchange some

HUILE 2011-01
Page 19 / 180
information/data. This means that the CAFC equipment (DCS, SCADA,
ESD/F&G, etc.) shall be housed in the electrical building inside the CAFC area.
In order to allow communication among the different parts of the plant, PAGA,
PABX TETRA and security radio telecommunication systems have been
foreseen as integration/extension of MLE systems. Also, Fibre Optical Cables
(FOC) shall be foreseen to exchange data between CAFC plant and remote
sites, and between CAFC and MLE plants, as per FEED documentation and
MOM interface meeting between MLE & CAFC PMT during CAFC FEED.
1.4 DEVELOPMENT LOCATION
The CAFC field lies within the Ledjmet Block 405b in the Berkine Basin of Algeria
approximately 1200 km by road from the Algerian ports. It is also approximately 220 km
south-east of Hassi Messaoud which is an oil field activities center and regional base for

HUILE 2011-01
Page 100 / 180
6.2 DESIGN HSE PHILOSOPHY
The design HSE philosophy is established with the intent to provide a framework and basis for
the design of CAFC project facilities to ensure that all hazards with the potential to jeopardize the
integrity of the project facilities and personnel attending the facilities have been identified and
risks have been reduced to As Low As Reasonably Practicable (ALARP).
The definition of the HSE design criteria during the detail engineering to be applied for CAFC
project facilities design shall be part of the CONTRACTOR activities to manage the HSE-related
risks during the entire performance of the work.
CONTRACTOR shall further define and develop the projects HSE philosophies for all CAFC
project facilities with the aim to collate and documents all the HSE design criteria and
philosophies, applicable regulations, codes and standards that are to be adhered regarding
design of the CAFC project facilities.
CONTRACTOR shall comply with, and further develop and update as necessary the FEED
project HSE philosophies during the EPC in consultation with and approval of the
CONTRACTING AUTHORITY.
CONTRACTOR shall comply with, and further develop and update as necessary the FEED HSE
documentations during the EPC in consultation with and approval of the CONTRACTING
AUTHORITY. Moreover CONTRACTOR shall agree with the CONTRACTING AUTHORITY on
the HSE deliverables to be prepared by the CONTRACTOR during the EPC phase.
Throughout the design of the installation, emphasis shall be placed on:
Provision of safe working conditions for personnel working on the installation facilities (and
immediate environs);
Protection of the asset;
Minimise the potential for hazardous occurrences;
Minimise the risk and consequences of an accidental event;
Provide sufficient safety devices and redundancy to isolate and minimise uncontrolled releases of
flammable and toxic substances;
Provide appropriate fire protection systems to rapidly bring under control and extinguish any
reasonably foreseeable fire which could develop during normal operations;
Protection of the environment and compliance with regulatory requirements;
Minimal damage to the environment under non emergency conditions;
Minimal adverse impact to the local community;
Minimum damage to equipment and prevention of long downtime or production deferment which
could be jeopardized by the occurrence of hazards inherent to hydrocarbon processing or any
other risks linked to an onshore processing facilities and industrial activities.
Ensure adequate means of Emergency Response (ER), Escape, Evacuation and Rescue (EER)
in the event of an incident.
The design philosophy is thus based on:
a) Elimination and prevention of hazardous incidents, as far as is practicable:
The application of codes of practice and standards, and performing the design in accordance
with Algerian Regulations and CONTRACTING AUTHORITY HSE minimum requirements,
standards and guidelines;
CAFC project facilities shall be designed in accordance with CAFC project document „Codes &
Standards‟ to be approved by the CONTRACTING AUTHORITY during the EPC phase‟;
Compliance with a project HSE Philosophies appropriate to CAFC project facilities;
Development of design and installation HSE systems based on the minimum requirements
established in this document and as they will be defined in the project HSE philosophies and
relevant CAFC project specifications.
b) Mitigation of the effects should a hazardous incident occur:

HUILE 2011-01
Page 101 / 180
Minimize the potential or frequency of hazardous events;
Control or mitigate the consequences of the hazards, including impact to the environment;
Define the requirements regarding asset protection, and ensure they are duly taken into
consideration.
c) Emergency Response (ER), Escape, Evacuation and Rescue (EER) in the event of an incident.
Provision of adequate escape, evacuation and rescue facilities.
6.3 HAZARD MANAGEMENT AND RISK MANAGEMENT
A goal setting approach will be applied to the project for its whole lifecycle. This will link the
processes of Hazard Management with Risk Assessment and other safety engineering studies
and reviews. Together, during the project phase, these facilitate confident and informed
engineering decision making which is directed at reducing risks to tolerable levels as the design
matures and demonstrating they are as low as reasonably practicable and appropriate for that
stage of the development.
CONTRACTOR shall submit during the detail engineering a final HSE Plan for engineering
clearly indicating the Hazard Management and Risk Management Process, (e.g. ALARP/ HAZID/
SIL/ QRA/EERA/HSE Impact assessments/HSE Case) it will use to implement HSE in the EPC
phase.
All studies shall form part of the overall risk management plan, to be developed during EPC by
the CONTRACTOR and submitted to the CONTRACTING AUTHORITY for approval.
All the methodologies for the required HSE studies shall be approved by CONTRACTING
AUTHORITY at the early stage of the detailed engineering and in any case before the
commencement of the studies.
6.3.1 GENERAL PRINCIPLES
A fundamental element of CONTRACTING AUTHORITY HSE Policy is that management of risk
is a continuous process and the cornerstone of all of the Contracting Authority HSE Elements.
The CONTRACTOR shall regularly identify the hazards and assess the risks associated with all
his Work. The CONTRACTOR shall take appropriate action to manage the risks and hence
prevent or reduce the impact of potential accidents or incidents.
Risk assessments shall be carried out to compare the risks as identified and analyzed with the
criteria for maximum acceptable risks as stipulated by regulations or defined by CONTRACTING
AUTHORITY policy. The guiding principle shall be that the project shall be able to demonstrate
that risks have been reduced to As Low As Reasonably Practicable (ALARP).
At the design stage significant efforts shall be made to manage hazards by the application of
Inherent Safety principles rather than by moving directly to control and mitigation methods.
ALARP principles (and Cost Benefit Analyses when required) shall be used to judge the
adequacy at each stage of the risk management process.
Consideration of HSE aspects shall be incorporated into all stages of the project in order that
issues can be addressed as soon as they arise. The earlier an HSE issue is identified, the easier
it is to address the issue and find a cost effective, practical solution.
It is the responsibility of the CONTRACTOR to demonstrate that the risks associated with CAFC
project facilities design comply with the CONTRACTING AUTHORITY requirements. Formal
studies methods shall be used to identify major hazards and assess risks so that adequate
protection features are provided.
The main studies to be carried out during the EPC are described in the following paragraphs.

HUILE 2011-01
Page 102 / 180
6.3.2 HAZARD IDENTIFICATION STUDY (HAZID)
A preliminary risk assessment, Hazard Identification Study (HAZID) has been completed during
FEED. As a result of this study a Hazard Register has been compiled detailing the Major
Accident Hazards. The findings and recommendations of FEED HAZID, performed during FEED,
shall be implemented by CONTRACTOR into CAFC project facilities design and operation during
EPC phase.
In every aspect of his Work, the CONTRACTOR shall carry out a risk assessment exercise to
identify Major Accident Events (MAE). Once on-site activities have commenced and prior to
commencing any new activity or as any condition changes affecting the previous analysis, a new
risk assessment shall be conducted. All resultant findings or action items necessary to
manage/control risks shall be updated in the Hazard Register.
The Hazard Register shall be maintained by the CONTRACTOR through out the Contract
duration. Any new Major Hazards and/or action items identified by the CONTRACTOR shall be
brought to the attention of the CONTRACTING AUTHORITY and addressed through the tracking
system.
During the detailed engineering of the EPC phase, CONTRACTOR shall perform new HAZID
follow up and shall perform a new HAZID to identify new possible Hazards related to CAFC
project facilities design , CONTRACTOR shall take in consideration the existing MLE facilities.
CONTRACTOR shall perform a Construction & SIMOPS HAZID before the commencement of
the construction activities.

the EPC phase after the HAZOP. A hazard risk analysis (SIL Assessment and Verification) shall
be undertaken for each protective function, based on the criteria defined in IEC 61508 and IEC
61511.
Note: no SIL assessment was performed during the FEED phase, thus CONTRACTOR shall
consider the implementation of any possible impact derived by the EPC SIL assessment.
HAZID, HAZOP and SIL sessions shall be led by a third party approved by CONTRACTING
AUTHORITY. Related costs shall be included and detailed in the lump-sum offer.
6.3.5 FIRE AND EXPLOSION RISK ANALYSIS (FERA)
A Fire and Explosion Risk Analysis (FERA) has been performed during the FEED; CONTRACTOR shall
perform a detailed FERA when proper project documentation will be available during the detailed
engineering.
The FERA Methodology shall be submitted to the CONTRACTING AUTHORITY at the early stage of the
detailed engineering for its review and approval.
A Blast Overpressure Study shall also be developed.
Note: during the development of the FERA, CONTRACTOR shall pose particular attention of its results
with respect to the blow down system design and philosophy. In fact, the current blow down philosophy
foresees that the plant is divided in two macro-areas: slug catchers area and process area. In case of
emergency, first the macro-area in which is detected the event will be depressurised and subsequently
the second macro-area. Once identified potential reciprocal impacts between the areas, CONTRACTOR
shall identify proper protective measures, since it is not acceptable that an event from one macro-area
could impact the second macro-area.

HUILE 2011-01
Page 104 / 180
6.3.6 QUANTITATIVE RISK ANALYSIS (QRA)
A preliminary Quantitative Risk Analysis (QRA) has been carried out at the FEED phase; CONTRACTOR
shall perform a detailed QRA when proper project documentation will be available during the detailed
engineering.
The QRA Methodology shall be submitted to the CONTRACTING AUTHORITY at the early stage of the
detailed engineering for its review and approval.
Note: it is CONTRACTING AUTHORITY intention to perform an overall QRA considering both CAFC and
MLE together, in order to determine the overall risks associated with the combined facilities.
CONTRACTOR could be requested to develop the study and/or implement resulting actions.
6.3.7 DESIGN CASE SCENARIO
The accidental scenario, both in terms of hazard likelihood and severity of consequences for assets,
identified for a specific plant area and considering all possible operating conditions (e.g. Construction,
SIMOPS), shall be used as a reference for systems design (e.g. fire fighting, F&G, safety distances, etc.).
Once the Design Case Scenario has been selected and its risk assessed against Risk Acceptability
Matrix for Assets, all the remaining risks shall be considered as Residual Risks and shall be analysed
through a QRA process.
6.3.8 DESIGN AND SAFETY REVIEWS
CONTRACTOR shall manage various design reviews and safety studies at the CONTRACTOR‟S
offices during the course of the Work. CONTRACTOR shall demonstrate by means of one or
more design reviews, as may be deemed necessary, that the design is safe, reliable, and

releases and maximize the capacity to deal with all possible emergency situations.
In addition to the requirements outlined in the FEED documents, the following intrinsic safety principles
governing plant layout shall be taken into account when locating the new facilities for CAFC Project:
The overall arrangement orientation will be such that the prevailing wind will tend to disperse any
hazardous release away from the safe area i.e. process equipment, hydrocarbon storage, and
flare and vent areas shall be located downwind of the safe areas. In locating the flare the
potential for dispersing flammables to be ignited shall be avoided either by separation or
orientation;
Adequate separation shall be provided between hydrocarbon-handling areas (hazardous areas)
and emergency services, main safety equipment, escape routes, areas to be non-hazardous and
permanently manned buildings;
Vents (if any) shall be located so as to cause minimum interference or hazard to plant and
personnel;
For gas systems, vent (if any) and relief valves shall be collected and discharged in safe location,
should the volumes to be vented be capable to create a hazardous condition;
The plant layout shall meet safety requirements for Hazardous Area Classification for electrical
equipment (See also Electrical System Design Section);
Adequate separation between flammable hydrocarbons and ignition sources shall be provided
and Limiting confinement and congestion in process areas; Units that contain large quantities of
flammable fluids shall be located so the prevailing wind will blow any vapour from an accidental
spill away from the plant;
Process piping and equipment, which are potential sources of hydrocarbon leaks, should be
routed so as to minimize the likelihood of external impacts (e.g. from vehicles, maintenance
devices, etc.);
Crash barriers shall be provided where there is any possibility of vehicle impact with pipelines,
HV transmission lines, fire hydrants, etc. (e.g. at road crossings);
Equipment shall not be located above live equipment for future phases nor shall it require lifting
above/across live equipment;

equipment served;
The inlet and outlet ESDV‟s of a plant shall be isolated or protected from the Design Case
Scenarios and survive at least the time required to safely evacuate the plant;

located away from any units having high fire potential.
6.5.2 MINIMUM SAFETY DISTANCES
Distances between units and equipment within the plant shall be established according to safe
accessibility aspects for operation and maintenance. Utilities shall be used as a “buffer” between

HUILE 2011-01
Page 108 / 180
As a minimum, all components or units that will be installed in plant areas shall be
arranged/located to observe the safety distances prescribed in the CONTRACTING AUTHORITY
standards and any other applicable standards identified during the EPC phase.
Separation distances for safe and hazardous areas shall never be less than required by the
results of hazard assessments (e.g. QRA, FERA, etc.)..
Note: CONTRACTOR shall pose particular attention to the position of slug catchers and flare KO drums

boundaries.
Fire zone definition carried out during the FEED stage shall be further reviewed and developed
during EPC phase. The grouping of units into fire zones shall be closely linked to the process
flow and arrangement.
Each fire zone largely incorporates complete process units, which upon an ESD level activation
with depressurization will not produce a depressurizing capacity that is greater than the
predefined capacity of the flare system. As the governing factor for grouping is the flare capacity,
this limits how far process units can be further grouped into larger fire zones. Furthermore,
grouping of units into fire zones also corresponds to assembly of units with a comparable level of
process risks.
6.5.4 ACCESS AND EVACUATION
6.5.4.1 ACCESS REQUIREMENTS
Access to the process / utility areas shall be available from all sides to allow for both fire fighting
and maintenance activities. Space should also be provided for lay down of equipment during

to their turning circles, and cranes, as necessary, to all site areas.
Site access roads shall be provided with barriers and access control facilities to prevent
unauthorized entry. All roads will be subject to appropriate speed restrictions.
Equipment shall be located such that these site roads do not pass through areas classified as
“hazardous”. Any road that of necessity is classified as hazardous shall be subjected to restricted
vehicular access and the area shall be indicated accordingly.
Roads shall provide access to all sides of the process areas and buildings for fire trucks, portable
foam equipment and equipment to supplement permanently installed fire monitors;

personnel. This area shall be located so when an emergency evacuation is required, the
operating personnel can go to the assembly area and be in a safe place; the assembly area shall
be safe in prevailing wind conditions.

The inlet and outlet ESDV‟s of a plant, SDV‟s and BDV‟s shall be isolated or protected from the
Design Case Scenarios and survive at least the time required to safely evacuate the plant.
ESD valves shall not auto-reset. Individual local and remote (under a detailed operating
procedure) reset shall be provided for ESD valves, only permitted once the shutdown cause has
been locally checked and removed. BDV shall have the automatic reset (and not local) in order to
avoid to forget some BDV opened before to re-start the plant.
The ESD System shall be characterized by logic with a number of intervention levels whose priority shall
be defined in relation to the extent of the deviations and their possible effects on production continuity,
personnel and equipment safety. The CAFC shall have a dedicated ESD System shall be structured on

systems are required to reduce the risks of loss of equipment integrity during a fire and/or to
reduce a local loss of containment arising from a leak which may otherwise lead to escalation
and the risk of catastrophic failures.
The blow down philosophy is to depressurise the plant, fire zone by fire zone (following the
results of QRA and Fire and Explosion Risk Analysis), in accordance with ANSI/API Std. 521.

design pressure, whichever is the lower, within 15 minutes from blow down initiation, in the
involved fire zone(s).Blow down valves (BDV) shall be specified with a fail safe (open) failure
mode and with air accumulator to avoid spurious opening in case of air instrument lack.
The following general requirements shall be taken into account:

both short term and long term exposure.
Continuous venting or flaring of flammable gas shall be avoided. However, if it is necessary to
provide atmospheric vents from equipment or packages in flammable gas service, they shall be
collected in a common vent stack discharging at safe location.
The design objectives will be to operate without continuous flaring (except where specific consent
is granted, e.g. for start-up operations or other specific purposes). The flare collection headers,

HUILE 2011-01
Page 112 / 180
KO drums, risers and flare tips will be sized to cope with the maximum emergency loads.
Adequate system shall be provided for the flare headers to prevent air ingress and burn back.

burning of surplus flammable vapours produced from the plant.
The flare and corresponding sterile area shall be located and designed with due attention to all
relevant flaring rates and wind conditions to ensure that the heat radiation will be within
acceptance limits in all areas of the installation and of the neighbours, with due regard to
exposure of operators, structures such as cranes and towers, electrical and mechanical
equipment and piping.
The flare flame or hot gases shall not represent a hazard due to increased surface temperature
in exposed areas. Particular attention should be paid to cranes, towers, structures and personnel

area, in order to enable personnel to listen to vocal messages or alarms from any point of the plant. The
system is supported with flashing lights in areas where noise levels are elevated.
Emergency lights and sirens shall be located throughout the facilities to alert field personnel in case of
emergency. Standard visual and acoustic signals, automatically activated by F&G detection or MAC
activation, shall be as shown in the following table.
Gas Alarm Cause Gas detection (at upper detection threshold)

(600 1250Hz) repeated with a 0.25” cycle
(1)
Visual Indication Red flashing light in all plant areas
Fire/General
Alarm
Cause Confirmed fire detection or MAC activation
Acoustic Signal AS4 (SLOW WOOP) corresponding to a bitonal rising
sound (500 1200Hz) repeated with a 4.1” cycle
(1)
Visual Indication Red continuous light in all plant areas
NOTES :
(1)
AS3 signal takes priority to AS4 and can silence it during simultaneous emergencies. Head of
Plant‟s messages take priority and usually silence other acoustic signals.
6.10.3 ALARM VOTING FOR AUTOMATIC ACTIVATIONS
All loops and detectors shall be arranged such that any arising hazard can be easily located. A
F&G Cause/Effect Matrix shall detail the alarms and executive actions taken on fire, gas, heat
detection or manual activation. Detection in one loop (except for fusible plugs) or in one detector
shall provide an alarm only.
Any firefighting or shutdown/depressurization actions required to automatically occur in the
hazardous process areas shall require a voting system of instruments. At least two detection
devices (as a minimum 2ooN voting logic) in the same voting group shall be provided to sense
the hazard before an automatic action occurs.
6.11 FIRE PROTECTION SYSTEMS
The plant fire protection is achieved through a combination of the following:
Active Fire Protection, by means of extinguishing or cooling agents (e.g. water, foam, inert gas)
either manually or automatically activated on fire detection.
Passive Fire Protection, by means of intrinsic safety principles (e.g. adequate spacing between
equipment, containment by bunds or kerbs, drainage) or barriers/coatings on structures, which
provides protection against heat transfer.

HUILE 2011-01
Page 118 / 180
Note: FEED requirements for active/passive fire protection have been developed in accordance with the
preliminary FERA and shall be updated according to the final FERA to be carried at the EPC phase.
6.11.1 ACTIVE FIRE PROTECTION REQUIREMENTS
The general philosophy for Active Fire Protection systems design is to identify critical facilities
and buildings requiring fixed fire protection systems and areas where mobile/portable fire fighting
systems need to be provided in order to permit to operating personnel to control small fires.
The fixed fire fighting system will be designed based on the assumption that only one fire at a
time may occur in the plant; the requirements for fire extinguishing and cooling facilities will be
then calculated for the worst possible fire scenario, according to standards requirements. Active
fire protection systems shall also be designed and located taking into account environmental
conditions (i.e. wind direction, atmospheric corrosion).
6.11.1.1 FIREWATER PROTECTION SYSTEM
The firewater protection system as defined at the FEED stage shall be reviewed and verified by
the CONTRACTOR to reflect the design development during the EPC and considering the
results and the recommendation of the FERA and the other HSE studies (e.g. QRA, ).
CONTRACTOR shall perform a design review of the fire fighting system at the end of the EPC
phase.
Note: for the design of the fire fighting system, CONTRACTOR shall take into account that the firewater
flow rate is fixed since provided by the MLE plant firewater system. In case this value is exceeded, proper
reduction measures shall be implemented.
6.11.2 PASSIVE FIRE PROTECTION REQUIREMENTS
Passive Fire Protection is required where intense fire exposure can cause the collapse of
equipment, the spread of burning liquids, and the loss of operability capabilities of critical
systems. The aim of passive fire protection is then to avoid the escalation of the emergency, due
to the collapse of heavy structures or equipment containing dangerous fluids (e.g. flammables).
In particular, the purposes of passive fire protection are as follows:
To prevent, within a specified time, the collapse of steel work supporting equipment containing
flammable materials via fireproofing. The release of such materials would increase the intensity
of a fire and the problems and hazards of search and rescue and fire fighting (i.e. to limit the
escalation of fire between adjacent fire areas).
To protect safety critical equipment for a period sufficient to fulfil its function.
As a minimum, fire resistant materials shall be provided as primary protection of:
Structures directly or indirectly supporting significant hydrocarbon inventories or emergency
systems. Structures supporting heavy loads which, where their failure would lead to a significant
hydrocarbon release, or catastrophic failure, loss or damage to a control centre or emergency
system;
Class 0 hydrocarbon storage vessels or other plant that could fail catastrophically or lead to
further significant releases.
The requirements for passive fire protection coatings on structural steel will be based on an
assessment of the implications for further loss of hydrocarbon containment following structural
failure, and the durations of fires relative to the time necessary for structural failure to occur.
FEED requirements shall be reviewed and detailed according to the results of the HSE studies to
be carried out by the CONTRACTOR during the EPC phase.
The extent of provision of structural passive fire protection shall take into account the hazard
distances presented by credible fire scenarios, considering also the benefits of depressurization
systems in reducing fire durations and hence heat doses to structures. Identification of fire

11. SPECIAL NOTES REGARDING CAFC OIL PROJECT
The Scope of Wok (SOW) as indicated in all the technical documentation contained in the ITT
Annex 1 is derived from the original competitive FEED for the development of the total CAFC
facilities which included the SOW for both OIL and GAS projects.
Subsequent to the completion of the competitive FEED, the project was split into two separate
projects:-
CAFC Oil
CAFC Gas Gathering
This ITT refers to the CAFC Oil Project, and any residual reference to CAFC Gas Gathering in
the ITT documentation should be ignored, or at best used “for information only”.
This Section (11. Special Notes Regarding CAFC Oil Project) is intended to advise last minute
changes or updates to the basic technical documentation contained in the ITT Annex 1.
11.1 CAFC OIL GATHERING SYSTEM
1. The original competitive FEED documents were prepared for the total CAFC facilities
including the lean and rich gas gathering system consisting of 10 lean gas wells, 7 rich gas
wells, 17 gas flowlines, 3 gas manifolds stations and 2 gas trunklines. The lean and rich gas
gathering system is presently under implementation as a separate project and does not form
part of this Work. The Gas Gathering system is expected to be commissioned before, and be
in operation during, the construction phase of the CAFC oil project.
2. The lean and rich gas wells are located in the same area as the oil wells and some of the gas
flowlines and trunklines are run in the same pipeline corridors as the oil flowlines and
trunklines. Contractor must consider existence of these live facilities in close proximity of the
work sites in design and construction of the CAFC oil facilities.
3. Power supply for some oil wells and manifolds is to be taken from the nearby gas well pads
/manifolds as detailed in the FEED documents
4. The well names and locations of some of the oil producer, gas injection and water injection
wells have been revised. These are also preliminary and are subject to change during the
EPC phase.
5. To avoid any confusion, the manifold MOP-01 shall be split into two separate manifolds at the
same location. Each manifold shall be connected to a maximum of 8 wells and will be
dedicated to each trunkline F6-1 and F6-2 separately. Note that the separation distance
between the manifolds shall be determined according to FERA rules and guidelines.
6. The Tagi, F6-1 and F6-2 oil flowlines and trunklines shall be submitted to 100% X-ray
inspection in accordance with the “Algerian safety regulation for transportation pipelines
intended for combustible gas”.

11.2 PIPING SPECS
Piping specs originally included in the competitive FEED have been further developed during
the CAFC Gas Project and are to be used for the Oil Project. The main difference relates to
the 600# piping classes where the Gas Project uses RTJ flanged connections instead of RF.
There are a few minor differences in other classes.
SEE ATTATCHMENT G
11.3LEGEND SHEETS
The development of the CAFC Gas Gathering Project has produced a set of P&ID Legend
Sheets which reflect the changes in piping classes noted above as well as further
developments during the detail design. These Gas Project P&ID legend Sheets are to be
integrated into the Oil Project and a set of Oil Project P&ID Legend Sheets developed during
the detail design which is mutually compatible with the Gas Project.

11.4FLOWLINE MODIFICATIONS
In addition to the instrumentation shown on the P&ID‟s, all flowlines are to include for a
Temperature and Pressure Indicator (TI & PI) at the end of each flowline.
11.5 INSTRUMENTATION MODIFICATIONS
All the instrumentation devices shall be provided with Ex-i (and not Ex-d) electrical execution.

11.6 RING MAIN UNIT PACKAGE
The CAFC GAS Project has developed the technical specifications for the Active and Passive
Cooled Shelters.
The ring main unit consists of No.5 Manifolds, No.1 Wellsite and all the other wells, in which
will be installed electrical/instrumentation shelters complete with all necessary electrical and
instrumentation equipment (in separate rooms). In the manifolds and wellsite will be installed
shelters active cooled (ACS) type while in each well will be installed shelters passive cooled
(PCS) type.
The ACS will be complete with MV and LV switchboards, MV/LV transformers, UPS and
batteries, RTU SCADA, SHD, IDS and TETRA System if necessary.
The PCS will be complete with LV switchboards, UPS and batteries, RTU SCADA, SHD and
IDS.
These shelters shall have also F&G system, with detectors, etc.
As for the Gas Gathering system, the connection between No.5 Manifolds and No.1 Wellsite
shall foresee an interlock (mechanical) philosophy between the disconnector and the earthing
switch installed in the same panel and a key interlock between the earthing switch and the
disconnector installed in the site connected to.
The closing of all earthing switch shall be possible only in case that the disconnector
downstream and the disconnector upstream shall be open.
