INTRODUCTION
1.1
Background
This document outlines the general Health Safety and Environment Philosophy to be adopted
for the detailed design of the Phase 2 and 3 of the PM-3 Development. The phase 2 and 3
developments comprise:
Phase 2
Installation of a Central Processing Platform (CPP) facility at Bunga Raya
(BR-A) with a bridge linked wellhead riser platform (BR-B), and a combined
wellhead platform for Bunga Seroja and Northwest Raya fields (BS-A). All
wellhead platforms will be tied into the CPP where the reservoir fluids will be
processed to meet a sales gas export specification and a stabilised oil
specification for export via shuttle tanker.
Phase 3
Installation of two wellhead platforms at East Bunga Kekwa-Cai Nuoc field
(BK-B and BK- C).
Sales gas will be exported via subsea pipeline to Malaysia and Vietnam. Stabilised crude oil
is exported via a floating storage and offloading (FSO) facility.
The HSE Philosophy documented herein is applicable to the CPP, BRB (WHRP) and satellite
platforms unless otherwise stated.
1.2
Purpose
The purpose of this philosophy document is to enable the identification of major hazards that
could lead to:
1.
2.
3.
4.
Injury to personnel,
Damage to facilities,
Loss of production, or
Pollution of the environment.
Once these hazards have been identified, the HSE objectives that will be adopted in the
design of the facilities will be specified. The subsequent designs shall be able to reduce the
risk to an acceptable level, by minimising the likelihood of adverse incidents and ensuring
that effective means are provided to minimise the consequences of adverse incidents.
The development of these HSE objectives and the subsequent design shall be based upon
established legislation, regulations, codes and standards and general good practice in the
industry.
This basic philosophy document shall be the preliminary background requirement and the
approach to be followed in the development of the detailed design in accordance with good
engineering practice for this new offshore installation complex.
The information contained in this document is of a general nature and is to be further
developed during detailed engineering phase.
The scope shall generally encompass hazard identification and assessments, consideration
of specific areas and technical requirements for active and passive fire protection and
detection system.

1.3
Basis of Philosophy
1.3.1 The general approach to developing the HSE Philosophy is as follows:
1.
2.
3.
4.
5.
6.
Identify hazards to personnel, environment and assets
Analyse the identified hazards
Develop the philosophy for addressing the identified hazards
Selection of a strategy to deal with the hazard
Optimisation of design to minimise risks from the facilities
Provision of systems to manage and control hazardous events
1.3.2 Strategies for eliminating risk
Having established the various aspects that may put the personnel, the production
facilities and the environment at risk, it is the objective of this HSE philosophy to
identify the means, by which these aspects are to be eliminated, managed or
controlled.
The possible strategies to achieve this shall be:
1.
2.
3.
4.
5.
6.
Loss Prevention;
Fire Prevention;
Fire containment and prevention of escalation;
Protection of personnel;
Evacuation Escape and Rescue; and
Acceptance of consequential damage (Acceptability Criteria).
The approach adopted for the acceptance of consequential damage and all strategies listed
above shall be evaluated during the Quantative Risk Assessment (QRA) studies.
Hazard quantification shall identify the size, duration, release rate and intensity of all major
fire cases in the selection to generate the appropriate hazard management philosophy.
Generally, industry approved, methods/software shall be used.
1.3.3 Studies to determine potential causes of failure.
The potential causes of failure must be identified and the combination of design features
and operational procedures put together to address each one of the failures. The causes of
the failure can be identified by the Hazard Identification Study (HAZID). This shall be verified
by the Hazard and Operability Study (HAZOP) during detail design. The studies shall include
the following:
1.
2.
3.
4.
5.
6.
7.
8.
9.
Fire effects
Impact by vessel
Corrosion
Environmental effects
Breach of containment
Overpressure
Explosion
Isolation failure
Simultaneous production and drilling (SIPROD)
Contributing elements to failure should be identified and adequate preventive measures in
keeping with applicable codes and standards and normal operational procedures should be
embodied in the design.
HSE Philosophy
Protek Engineers Sdn Bhd is a member of the JE Group
Page 5 of 35

Development
There are some hazardous events, such as uncontrolled riser failure, with potential to
overwhelm the installation should they occur. These can be classified as extreme accidental
events and the design to withstand these events, including the Temporary Refuge (TR)
design, may not prove cost beneficial in the balance of analysis.
The aim should be to reduce the risks from these events to within acceptable limits or to
levels As Low As Reasonably Practicable (ALARP).
1.3.4 Implementation of minimisation and control measures
The purpose and mode of implementation of the following minimisation and control
measures, developed from the design codes and other analysis techniques, shall be
investigated:
1.
2.
3.
4.
1.4
Inventory minimisation
Optimising the location of potential release
Control of gas and liquid releases
Control of fire spread
Legislation, Regulations, Codes & Standards
The philosophy and system design shall be in accordance with the current legislation and
mandatory provisions, if any.

SAFETY PHILOSOPHY
2.1
Design Criteria
The facilities will be designed in accordance with the safety standards required by Legislation
and the As Low As Reasonably Practicable (ALARP) risk principles. A third party specialist
safety contractor shall be engaged to carry out a Quantitative Risk Assessment (QRA) Study.
This study shall form the basis for the Contractor to verify the principles and the design with
the general objective of ensuring that the risk is reduced to satisfactory ALARP levels.
Other safety aspects will be incorporated into the design as dictated by the specifications
issued by COMPANY.
Where no standards exist to cover a specific aspect, the standards, procedures, and normal
good engineering practice shall be used.
The philosophy shall assume the occurrence of only one major incident at one time on the
basis that the design of the facility reduces the escalation of cascading events.
2.2
2.2.1
Principles of Platform Layout
General
This section covers the main features that shall be considered when laying out an
installation. Careful attention to equipment location can improve the safety,
access/egress and the efficient operation (operability) of the installation.
Due consideration shall be given to the location of process equipment, treatment
systems, utilities, the accommodation module and the helicopter landing deck, as
well as escape routes, life saving appliances and safety equipment, having regard to
the relevant hazards.
The first approach to layout is to grade each system according to the nature of the
hazard and then categorise the systems of similar grading as follows:
1.
2.
3.
4.
5.
Systems which have the potential to emit flammable material
Systems which may emit toxic gases
Systems which are a source of ignition
Systems which must be located in a safe area
Systems which are considered safe
Typically, sources of flammable material must be segregated from sources of
ignition and accommodation areas well separated from sources of flammable gas.
For this reason, a fire wall and/or a blast wall is required between the process areas
and the LQ, TR and utility areas. The exact requirement to be developed during the
detailed design phase in conjunction with the various studies given herein.
Although leaked hydrocarbon gas would normally be rapidly dispersed by wind and
buoyancy effects, for the duration of the leak gas jets/clouds within the flammable
limits may form within the area of the platform.
It is therefore necessary to clearly define the methodology to be used for the
determination of hazard zones for major gas leaks that are likely to result in gas
jets/clouds within the flammable limits. This methodology defined shall be applied
through a preliminary risk analysis exercise for all piping streams and equipment
containing hydrocarbon.
HSE Philosophy
Protek Engineers Sdn Bhd is a member of the JE Group
Page 9 of 35
Provision of Basic Engineering Design Services For Phase 2 and Phase 3 of PM3
Development
A Flare Dispersion Study that examines flare flame-out conditions using the
prevailing wind direction, or vent dispersion study, should be conducted for the
maximum blowdown flowrate with expected process characteristic assumed.
A comprehensive hazard analysis must also be carried out to determine the fire
zones due to gas leaks from vessels and pipework. Such zones must be segrated by
bulkheads or decks or by distance such that the heat from a fire in one zone will not
propogate the emergency into another zone. The location of ESD valves to split the
systems must also be considered in the design and analysis.
Within fire zones, it shall be possible to suppress all ignition sources to prevent an
explosion when a flammable gas cloud is drifting towards them. A blast study shall
be conducted in conjunction with detailed design.
Depending on the nature and location of the ignition sources, the suppression shall
be:
1. Permanent, using “Ex” electrical equipment and heat generating pieces of
machinery suitable for use in explosive atmosphere,
2. Automatically controlled, when gas is suspected to drift toward or is detected
around the fire zone,
3. Manual locally controlled, when the available reaction time allows.
2.2.2
Utility & Accommodation Areas
The design shall locate non-hazardous areas to maximise safety with regard to the
prevalent wind direction. Utility areas are generally considered to be less hazardous
and are to be used as a “buffer” to segregate high risk areas from the
accommodations.
No hydrocarbon riser pipework should run under or within a horizontal distance of
100ft of a TR/LQ, central control room, fire pump, emergency power source, radio
room or other facilities essential to the safety of the installation in an emergency. If
the present distance, which conforms to this requirement, is maintained, then risers
will need no passive fire protection. This is to be confirmed during detailed design.
2.2.3
Helideck
The location of the helideck is governed by the following criteria:
1.
2.
3.
4.
5.
It must be a safe area
A clear approach angle of 210o is required
Structure induced turbulence should be minimised
The approach/take-off sector should be into the prevailing wind
Consideration should be given to the location and operability of the helideck
when designing/installing equipment exhausts
6. Drain gutters shall be bunded externally to the maximum height permitted by the
codes to prevent high winds carrying burning fuel of the deck
7. A safety net must be installed around the perimeter of the helideck
8. Compliance with Malaysian regulations
HSE Philosophy

Development
2.2.4
Combustion Equipment
2.2.5
Generally, combustion equipment and engines shall be located in non-hazardous
areas. If it is not possible to locate them in safe areas, mechanically ventilated
enclosures, along with fire and gas detection, are required to make the area safe.
Shutdown Valves
Riser/pipeline isolation valves shall be located directly below the lowest deck and, as
far as possible, are to be protected against fire and mechanical risks. Mere proximity
to other risers does not constitute a risk.
The location of shutdown valves on the topsides process shall be optimised in order
to sectionalise the process and minimise the inventory available to feed the release.
2.2.6
Hydrocarbon Pipework
Live hydrocarbon pipework must be located to minimise the risk of mechanical
damage by operations such as crane movement, drilling or workover. Flanges and
points of potential leakage shall be minimised in general.
Live hydrocarbon pipework shall be routed such that it does not pass through
confined or enclosed safe areas. Where routing through and open safe area is
unavoidable, live hydrocarbon pipework shall not have flanged or screwed
connections that affect the areas classification.
Liquid pipework shall not be routed through rooms containing electronic or electrical
systems.
2.2.7
Bridge Isolations
A means for isolating all hydrocarbon bridge crossings between the CPP and BRB
(WHRP) is required except for vents, flares or drains. This as a minimum shall
include for each line, a check valve on the receiving platform and an ESD valve on
the sending platform. In case of bi-directional flow an ESD valve shall be located on
each line on each platform.
2.2.8
Bridge Lengths
No restrictions are made on length of the bridge between the CPP and BRB (WHRP)
except as required by the safety studies. (The minimum bridge length is determined
by structural considerations).
2.3
2.3.1
Identification of Hazards
Hazard Identification
Hazards are identified with reference to the aforementioned documents. For a particular area
of the installation, the layout drawings are to define the type of equipment installed.
If the area contains process or utility systems, reference to the flowsheets provides
information on the nature of the hazards, e. g.:
1. Process conditions: pressure, flow, temperature
2. Composition:
flammable liquid or gas
HSE Philosophy
Protek Engineers Sdn Bhd is a member of the JE Group
Page 11 of 35
Provision of Basic Engineering Design Services For Phase 2 and Phase 3 of PM3
Development
Further reference to the P&ID provides the location of the sources of hazards including
vents, drains, flexible couplings or removable covers. In general, hydrocarbon equipment of
a high inventory, high pressure or high throughput is also considered to be hazardous.
2.3.2
Hazard Investigation
It is important to investigate how operations in an area may contribute to the risk. Such
operations may be:
1. The crane lifting of heavy items above wellheads or process/treatment equipment.
2. The venting of large quantities of hydrocarbon gas. Gas dispersion studies shall be
conducted on the vents at relevant hazard levels (LEL) to check the extent of
plumage. The hazard levels to be investigated should be selected based on the Gas
detection system set points.
3. For a case of simultaneous drilling or workover and production, the design shall
generally incorporate precautions to be implemented for the offshore installations
and the attending vessel during SIPROD.
4. Requirements for compliance with Health and Safety at Work regulations with
regards to chemical products and their handling shall be identified and addressed.
5. Emergency response plans shall be developed for manned and unmanned platforms
with due consideration to operations, evacuation, escape and rescue of personnel
using escape routes, liferafts, lifeboats, attendant vessels or helicopter. These plans
shall consider emergencies during drilling and workover activities in addition to those
during normal production. The emergency plan shall be developed based on the
major hazard scenarios assessed in the QRA and other safety studies.
2.4
2.4.1
Hazardous Area Classification
Hazardous Area
The electrical classification of areas shall be in accordance with IP 15 and applicable project
electrical documents. The molecular weight of the gas is considered between 21 and 46.
This is to be confirmed by the process stream data from the steady state simulation analysis.
For the purpose of hazardous area determination, the gas will be considered as “heavier
than air” because its density is more than 0.75 the density of air.
All hazardous areas will be given a zone classification depending on the degree of hazard.
The basis for area classification shall be in accordance with the definitions laid down in
Hazardous Area Classification (IP 15), i.e.
1. Zone 0
2. Zone 1
3. Zone 2
a zone in which a flammable gas/air mixture is continually present.
A zone in which a flammable gas/air mixture is likely to occur during normal
operations.
A zone in which a flammable gas/air mixture is unlikely to occur during
normal operations, and would only be of a short duration.

2.4.2
Non-Hazardous Area
A non-hazardous or safe area can be defined as an area in which a flammable gas/air
mixture is not normally expected to be present and which can form part of a general
restricted area within the facility in which all operations (routine or unusual) are carried out.
Where non-hazardous areas are located within hazardous areas, pressurisation along with
airlock entrances with gas tight, self-closing doors shall be provided.
Further reference to area classification should be made to Hazardous Area Classification
Drawings to be prepared for this development.
By design, the following areas shall be defined as “non-hazardous” either by virtue of
location, ventilation or by over-pressurisation:
1.
2.
3.
4.
5.
6.
7.
Living Quarters (Level 1 & 2)
Control room
Switchgear room
Fire Pumps
Emergency Generator
General Utilities
Battery room (special consideration shall apply owing to battery venting and
possible H2 generation. Negative pressurisation shall be provided by means of
exhaust ventilation).
Careful consideration shall be given to the utility facilities regarding the layout. Care shall
be taken to segregate hazardous from non-hazardous equipment.
In hazardous areas all electrical equipment shall be certified for Gas Group IIA and
temperature class T3 as a minimum. Equipment operating in confirmed classified areas
shall have the necessary classification rating.

Environmental Protection
Health and Safety of Personnel
In the conduct of the Company’s activities, paramount importance is given to the health and

FIRE PROTECTION PHILOSOPHY
3.1
Introduction
This section covers the philosophy for the fire protection systems of the CPP and BRBWHRP facilities.
The other satellite and BRB (WHRP) platforms are not normally manned. They are therefore
designed with minimum facilities and hence do not have the fixed fire protections systems
discussed below for use during normal operations. A fire water ringmain pipework is to be
installed on these platforms but is for use only during simultaneous production and drilling
(SIPROD) and will be fed from the drilling rig.
Only the discussion of portable fire protection systems is applicable to the BRB (WHRP) and
satellite platforms.
3.2
Objectives
The objectives of the fire protection design are as follows:
1. To ensure that an acceptable level of safety is achieved. The protection of personnel,
the installation and the environment, from fire and explosion is of primary importance.
2. To provide a basic concept on which the detailed design of the various safety systems
can be based.
3. To ensure that the supply of the firefighting equipment is adequate to meet the needs of
the design, and the appropriate statutory regulations.
3.3
Background
Major incidents often escalate from relatively minor occurrences involving the three elements
of the fire triangle, namely:
1. Fuel,
2. A source of ignition, and
3. A source of oxygen (air).
Exclude any of these elements and a fire will be avoided or extinguished, however if they are
all present, a fire will continue and may well escalate by involving further sources of fuel.
Thus, the basic requirements of the fire and gas detection and protection system are as
follows:
1. Detect this release of fuel/gas as rapidly as possible
2. Upon detection of a gas leak or fire, simultaneously:
a. Isolate the source of fuel/gas
b. Isolate sources of ignition
c. Attempt to disperse the fuel/gas
d. Apply extinguish ant (fire only)
e. Protect adjacent equipment to prevent escalation of the incident
f. Exclude air where possible
g. If the fuel source ignites, detect the fire as quickly as possible.
3.4
Fire Zones
HSE Philosophy
Protek Engineers Sdn Bhd is a member of the JE Group
Page 17 of 35
Provision of Basic Engineering Design Services For Phase 2 and Phase 3 of PM3
Development
The design of the fire protection systems assumes that only one major incident occurs at any
one time. To prevent incidents escalating beyond the capacity of the extinguishing systems,
as far as possible installations should be segregated into fire zones protected by fire resistant
bulkheads, the extremities of the platform and decks, or a combination of both. (refer to
Section 2.4).
3.5
Fire Extinguishing
The extinguishing medium must be suitable for the anticipated type of fire. Agents include
water, foam, dry powder and CO2. The advantages and limitations of each are detailed in
subsequent sections of this document. The compatibility of the various extinguishing means
must be considered.
3.6
Reliability, Maintenance and Standards
3.6.1
Reliability
The safety systems must have a high reliability level to ensure that they operate as
intended, when required, and to avoid spurious operation and consequential
disruption of production. To avoid human error, particularly during emergency
situations, automatic systems should be specified wherever possible. System
reliability is improved by ensuring complete autonomy, diversity, multiplicity and
redundancy as appropriate.
3.6.2
Maintenance
System should, where possible be self diagnostic so that the operator is immediately
informed of any faults. With built-in redundancy these should not affect operation of
the safety systems. Safety equipment should be readily accessible, easy to maintain
and spare parts should be readily available. Standardisation of equipment will
minimise the spare parts holding requirement.
3.6.3
Standard of Equipment
All fire and gas detection and protection systems will be in accordance with the
appropriate regulations and design codes. Equipment should be of an approved
design, suitable for the environmental conditions and for the design life of the
installation.
3.7
Fire and Gas Detection System
The fire and gas detection system is explained in detail in the Fire & Gas System Philosophy.
3.8

PASSIVE FIRE PROTECTION
4.1
Introduction
Structural fire protection covers the provision of firewalls and protection for primary load
bearing structural members in hazard areas. Requirements for PFP shall be determined by
the radiation and heat profiles obtained from the QRA studies.
Structural fire protection is provided for the CPP facilities only. The satellite and BRB
(WHRP) platforms are not normally manned and are therefore designed with minimum
facilities and hence do not have structural fire protections systems discussed below.
4.2
Firewall
The objectives of firewalls are to prevent the passage of heat, smoke, flame and gases for a
sufficient period of time to: 


Enable the safe evacuation of personnel
Provide a safe haven for personnel
Ensure the operation of equipment required in an emergency
The temporary refuge (TR) shall be segregated from the rest of the CPP area by a H60 rated
firewall. The H class division firewalls are those divisions formed by bulkheads and decks
that comply with the following: 


4.3
They shall be constructed of steel or other equivalent material
They shall be suitably stiffened
They shall be so constructed as to be capable of preventing the passage of smoke and
flame to the end of the two-hour hydrocarbon fire test.
Structural Fire Protection
The objective of structural fire protection, if required, is only to prevent the collapse of critical
load bearing members, should they be involved in a fire situation, for a period long enough
for personnel to escape.
Critical load bearing structures are defined as follows: 

Primary steelworks in high risk areas where exposure to fire could rapidly cause collapse
of the installation
Secondary members in high risk areas that are exposed to fire could rapidly escalate the
incident.
The requirement for structural fire protection shall be evaluated and specified based on
safety studies to be undertaken during detailed design. Passive fire protection is only
required if studies to be performed during detailed design specify a requirement for it.
