PERMIT AND PROCEDURE FOR INITIAL

LIVENING OF ELECTRICAL FACILITIES

1. Introduction

This document addresses the livening of electrical facilities during the initial
energization program.

1.1 Definitions:

Energizing refers to making a system "Live" or electricity being put on to a system after
that system has been commissioned and is approved.
Livening refers to electricity being put on to a system for the "First Time" only.

2. Responsible Persons

To exercise direction and control over energization and carry out all necessary
switching operations under permit control, four officials are required. Their
responsibilities and duties are defined in detail in the permit procedure, Appendices 2 and
3.

The following gives a summary of the responsibilities and duties of the respective
officials.

2.1 Construction Representative:

There are a number of defined construction areas within the project, each having
its own electrical supervisor who is in charge of electrical construction work or in
charge of subcontractors doing the work. The electrical supervisors will be the
Construction Representatives (CR) for the livening of electrical facilities in their
respective areas. The Construction Representative will advise the Energizing
Coordinator which facilities are ready for livening, having confirmed the completion of
checkout of the facilities, the category 1 punch items and the withdrawal of all
construction personnel from the facilities. In the case of electrical facilities within sub-
stations, he will hand over control of entry into the building premises to the
Responsible Commissioning Engineer, Electrical, subject to the issue of an Interim
Acceptance Certificate for the sub-station building and on the signing of a "Ready
for Commissioning" (RFC) Certificate for the substation.

2.2 Energizing Coordinator (Area Electrical Representative):

The Energizing Coordinator (ECR) acting on behalf of and in support of

construction will initiate permits and switching requests and the preparation of
these in writing. He will coordinate the safe and orderly livening of facilities in a
manner that will ensure the prevention of exposure to inadvertent livening of
facilities still being worked on by construction.

He will ensure that energization of facilities takes place without hindrance to

PT. GLOBAL POWER SERVICES ©DOC2010 Page 26 of 62

Section 7 - E L E C T R I C A L

construction in progress.

He will prepare and submit detailed switching requests to the Responsible

Commissioning Engineer, Electrical, for review, approval and execution and will keep
detailed status records of the complete network and all isolation permits issued.

2.3 Responsible Commissioning Engineer, Electrical Horst Unger):

The Responsible Commissioning Engineer, Electrical (RCEE) will take over control of
facilities to be livened, lock up facilities to prevent unauthorized access or accidental
contact with live conductors and take all necessary steps to ensure safety of personnel
and plant equipment.

He will review and approve all switching requests before sanctioning these and passing
them on to the Energizing Controller for execution. The Responsible Commissioning
Engineer, Electrical will be the senior Operations Electrical Engineer carrying legal
appointment as fee official in overall charge of the permanent power distribution
network.

2.4 Energizing Controller (Name):

The Energizing Controller (EC) will be an Operations Representative nominated by

the Responsible Commissioning Engineer, Electrical and authorized to carry out all
switching required to energize or isolate facilities. The Energizing Controller will not
carry out any switching without recourse to an approved switching request, issued by the
Energizing Coordinator and passed on to him by the Responsible Commissioning
Engineer, Electrical, with whom he will review and agree to the switching request
before proceeding with switching.

3. Permit and Procedure

The permit and procedure are to secure permission to proceed with livening.

3.1 Permit:

The format of the permit which will be used is illustrated in Appendix 1.

3.2 Procedure:

The procedure for the initial livening of electrical facilities is detailed in Appendix 2.
It is consistent with Riau's practice and incorporates the minimum requirements to ensure
effective control for safe and orderly livening.

3.3 Principles Incorporated into the Procedure:

For clarity of how the procedure is structured and applied the following describes
the main principles and terminology incorporated into the procedure.

PT. GLOBAL POWER SERVICES ©DOC2010 Page 27 of 62

Section 7 - E L E C T R I C A L

a) The facility (Circuit) to be livened must be identified. Following checkout of all items of
equipment making up the facility and completion of Category 1 punch items, livening
of any section of a power distribution network or facility may only proceed after the
Construction Representative has notified the ECR that the electrical construction is
complete and the facility is ready to liven.

b) To make a circuit safe it must be electrically isolated from the source of supply. This
is accomplished by opening the feeder circuit breaker and isolating the switch.

c) To establish control over livening of facilities the Energizing Coordinator will,

prior to initial livening, prepare and issue switching requests to isolate all circuits
in the facility, both incoming and outgoing and all tie breakers (bus-couplers), and
will cause all feeder circuit breakers and tie breakers to be opened, locked out and
permitted out. He will initiate the isolation permit with the Responsible
Commissioning Engineer, Electrical, for incoming feeders and tie breakers. (These will
be locked out by the Responsible Commissioning Engineer, Electrical and the
Energizing Controller, each with his own lock.) The party to whom the permit is
issued becomes the permit holder.

d) A circuit under permit control is referred to as "permitted out". The permit holder
puts his own lock on the circuit breaker for the period of time he holds the permit,
to prevent anyone from inadvertently closing the circuit breaker and livening the
feeder.

The official responsible for switching (Energizing Controller) also places his lock on
the circuit breaker to prevent unauthorized closure of the circuit breaker. A copy of the
isolation permit is fixed to the circuit breaker and the circuit is then referred to as
"locked out, permitted and tagged".

e) The withdrawal of a permit (referred to as the "Permit Release") will be necessary to

allow a circuit to be made live.

No circuit may be made live unless the permit, against which it was isolated and
taken out of service, has been cleared.

The permit release thus becomes the main safeguard to control safe livening of
circuits as the permit release can only be affected by the holder's endorsement of the
Energizing Coordinator's master copy. The Energizing Coordinator will not issue a
switching request for the livening of a circuit until he is in possession of the cleared
permit.

f) The closing of any circuit breaker may only be done against a switching request issued
by the Energizing Coordinator and approved by the Responsible Commissioning
Engineer and this is the second safeguard to controlling safe livening.

PT. GLOBAL POWER SERVICES ©DOC2010 Page 28 of 62

Section 7 - E L E C T R I C A L

3.4 Actions Covered by Procedure:

There are only four different actions allowed for in the procedure, these being:

a) The issue of a switching request to isolate a circuit, together with the permit to cover
the isolation of a circuit to be locked out, prior to being energized for the first time.

b) The issue of a switching request to isolate a circuit, together with the permit to cover
the isolation of a circuit to be taken out of service after it has been energized and placed
into service.

c) Release (withdrawal) of a permit and issue of the switching request to return a

circuit to a "Ready for Service" condition (not energized).

d) Release (withdrawal) of a permit and issue of the switching request to return a

circuit to an "In Service" condition (energized).

4. Livening Circuits for Bump Testing of Motors

The procedure makes provision for a temporary release of the isolation/livening

permit to allow:

a) bump testing and uncouple test running a motor where its feeder circuit is isolated
and locked out under an initial isolation permit; and

b) access to a motor starter cubicle in order to complete construction work, necessitating

temporary removal of locks without livening of the circuit where the circuit is
isolated and locked out under permit.

5. Safety Locks and Keys

For the purpose of locking out feeders, three sets of locks will be necessary (one
set for each of the officials designated in paragraphs 2.1, 2.3 and 2.4). A
combination of only two locks applied simultaneously to a feeder circuit breaker
by two of the designated officials will be necessary to secure lockout in
accordance with the procedure.

Each official will retain control over the keys for his own set of
locks and it is proposed that the key combination for the locks be
arranged as follows: '

5.1 Construction Representative Locks (Red):

The Construction Representative will have a set of locks for his own area. Ideally,
each lock will have the same key (for different areas the locks must have different
key combinations).

PT. GLOBAL POWER SERVICES ©DOC2010 Page 29 of 62

Section 7 - E L E C T R I C A L

5.2 Responsible Commissioning Engineer. Electrical. Locks (Blue):

These locks should be keyed alike to obviate the need to carry around large
bunches of keys.

5.3 Energizing Controller Locks (Gold):

These locks should be keyed alike but with a different key combination to those
of the Responsible Commissioning Engineer set.

6. Operational Activities Covered by Procedures

The step-by-step procedural activities to be taken by each of the designated officials

and covering all possible operations, with which they will be faced, are tabulated in
Appendix 3. The following operations are covered:

a) Procedure No 1: To ensure that all feeder breakers (incoming and outgoing) and all
bus-section (tie) circuit breakers are isolated and locked out and to initiate permit
control over livening of facilities (prior to livening the facility under consideration for
the first time). Compliance with this procedure is essential to set up and place the permit
system in operation.

b) Procedure No 2: To take an energized feeder circuit out of service.

c) Procedure No 3: To take an incoming breaker or tie breaker out of service.

d) Procedure No. 4: To release a feeder circuit for service without energizing.

e) Procedure No. 5: To release and energize a circuit for service.

f) Procedure No. 6: To liven a feeder temporarily for construction testing and to isolate it
again on completion of the tests.

g) Procedure No. 7: To temporarily remove locks from motor starter cubicles, which are
isolated and locked out to allow access for completion of construction work?

h) Procedure No. 8: To release and energize an incoming breaker or tie breaker.

7. Switching Requests

Switching requests will be prepared by the Energizing Coordinator and issued to the
Responsible Commissioning Engineer, Electrical, for review and approval to cover each
and every livening or isolating operation which is necessary to execute. Appendix 4 is
a typical example of a switching request.

Permit and Procedure for Initial Livening of Electrical Facilities

1. Introduction

The electrical system energizing procedure and permit system is structured to achieve
two goals, namely:

- to provide maximum safety for all personnel during the energization of the
electrical system; and

- to avoid any delays to the completion of the construction program.

The procedure was developed from proven permit systems. From these proven permit
systems the basic safety elements have been incorporated and the administrative parts have
been simplified to satisfy the Riau situation.

The procedure is structured to be compatible with, and provide a smooth transition

to, the Riau Operations procedures as these are phased in to replace this procedure.
There will be no additional safety risk exposure during any turnover period.

The procedure is designed to function quickly and efficiently, as the steps involved
have been simplified and condensed to a minimum required while maintaining complete
safety.

Administration has been simplified to two operational documents and two database
records of those documents.

2. Documentation

2.1 Operation Documents

- Electrical Isolation/Livening Permit: This document serves two functions. In the first
instance, it provides a method to allow personnel to work safely on a portion of the
system which could be energized. Secondly, it provides a method to ensure agreement
that a portion of a system is ready and safe to energize and will be switched with the
required checks and in the proper sequence.

- Switching Request: This document provides a method to ensure that required safety
checks, equipment checks and switching operations are completed in the correct
sequence. The document provides a check to the switching operation and eliminates a one
man judgment condition.

PT. GLOBAL POWER SERVICES ©DOC2010 Page 41 of 62

Section 7 - E L E C T R I C A L

Section 7
Appendix 2
Page 2 of 10
2.2 Database Records

- System Status Record: This record provides a current complete picture of the electrical
system status as it is progressively energized. At any time it can be determined what
parts of the system are energized, de-energized and under permit or de-energized but
available for service. The information source for this record is the completed switching
request.

- Permit Status Record: This record provides a quick source of information to determine
at any time that has the permit for any one circuit or what circuits are permitted out to
any one individual. The information source for this record is the permits.

3. Responsible Persons and Duties

3.1 Construction Representative (CR)

The Construction Representative is THE RESPONSIBLE INDIVIDUAL DIRECTLY

IN CHARGE OF THE WORK BEING PERFORMED. This individual will need to
be appointed in writing.

For the Riau Project, the Construction Representative is either the Electrical
Supervisor in charge of the construction work or the Senior Electrical Supervisor of
the subcontractors doing the work within a defined construction area on the project. It is
the responsibility of the Construction Representative to ensure that any work to be
done on the electrical installation which could become energized, is done under
PERMIT control.
The Construction Representative in each construction area will have to appoint a backup
representative who can perform these duties in his absence.

The Construction Representative in each construction area will ensure that the project
safety standards are enforced for any work on the electrical installation.

The Construction Representative will:

- Initiate the request to obtain PERMITS for circuits where work is to be

performed and signs as recipient of these PERMITS.

- Initiate the requests to release PERMITS when the work is completed and the
circuit may be energized.

PT. GLOBAL POWER SERVICES ©DOC2010 Page 42 of 62

Section 7 - E L E C T R I C A L

Section 7
Appendix 2
Page 3 of 10

- Install a lock on any FEEDER circuit breaker of circuits where the work is
to be performed.

- Remove the lock on any FEEDER circuit breaker of the circuit where the
work has been completed.

- Place a lock on all FEEDER breakers which he has taken out under permit
and retain the keys.

- Confirm that the correct feeder circuits have been taken out of service and
certify the PERMITS accordingly.

- Confirm that the correct feeder circuits have been released for service and
approve the PERMIT RELEASE.

- Confirm that the correct circuits have been energized when the circuits are
placed into service.

- Ensure that any electrical circuit or equipment to be energized is clear of

personnel and safe to energize.

3.2 Energizing Coordinator

The Energizing Coordinator is THE OFFICIAL IN CHARGE OF

CONTROLLING RECORDS AND SWITCHING REQUESTS FOR THE
ENERGIZATION OF THE ELECTRICAL SYSTEM. This individual will need
to be appointed in writing (Area Electrical Representative).

The Energizing Coordinator will have to appoint a backup representative who can
perform these duties in his absence.

The Energizing Coordinator will:

- Prepare all requests and releases of PERMITS and initiate isolation, lockout
and permitting out of all circuits comprising any defined section of the power
distribution network scheduled for livening.

- Provide the detail SWITCHING REQUESTS to energize any part of the

electrical system.

- Submit all permits and switching requests to the Responsible Commissioning

Engineer, Electrical for review, approval and execution.

PT. GLOBAL POWER SERVICES ©DOC2010 Page 43 of 62
