1.0 Purpose

1.1 This document has been produced to provide guidelines in the preparation and operation of

"Permit to Work" Systems. It is intended to provide sufficient guidelines to ensure a

consistent approach within all operating areas of CNOOC SES Ltd, to avoid confusion by

personnel and contractors working on different Company sites and facilities.

1.2 Permit to Work Systems are intended to maintain a high level of safety by reducing the

chances of misunderstandings when Non-Routine, Formal Procedure (SOP) and Non Permit

to work activities are to be carried out.

1.3 However, a "Permit to Work" System is only part of the overall safe work system. An effective

safe environment can only be achieved through systematic planning, risk assessment,

communication, coordination, training, checking, and implementing precautions, monitoring

of the worksite, and inspection on completion of work.

2.0 Scope

2.1 This procedure contains mandatory requirements for all facilities operated by CNOOC SES

Ltd. as a rule:

"must" or shall indicates a mandatory course of action

"should" indicates a preferred course of action

"may" indicates a possible course of action.

2.2 This procedure has been developed for control of Non-Routine, Formal Procedure and Non

Permit work in all CNOOC SES Ltd hydrocarbon-processing facilities. These guidelines are

the Company Standard.2.3 It is strongly recommended that, for non-hydrocarbon processing facilities the Line Manager

responsible for the site reviews these guidelines and adopts relevant sections, as

appropriate, to the hazards in the workplace.

2.4 At a more complex and hazardous site (e.g. marine vessel) where work control is required,

this procedure must be followed.

2.5 For construction sites permit procedures are required as per this procedure.

2.6 For sites involved in the commissioning of equipment for hydrocarbon processing facilities it

is recommended that the Permit to work system adopted be in compliance with this

procedure.

6.2 Flow

6.2.1 Performing authori ty

The Performing authority will fill out (Sections 1 & 2) of the Permit to Work form

after visiting the worksite, every effort must be made to visit the location of the

work but due to logistic problems ( Remote locations its not always possible to

do a worksite visit).

The Performing authority will answer all concerning issues and pointing out any

special recommendations if applicable. This will be done after he has inspected

all safety measures required on the Permit.

6.2.2 Review by Area Authority

The Performing authority will present the Permit to Work request to the Area

Authority for review. The Area Authority will check the Task Risk Assessment in

section 2 and the safety controls identified for that work and will highlight any

additional requirements such as additional Gas Test requirements to the Work

Permit. The Area Authority then presents it to the Site controller for authorisation.

6.2.3 Authorization by Site Contro ller

The Site Controller will view all the safety measures identified and may request

additional safety measures, etc. The Site Controller then signs to authorise the

permit (Section 5), this does not mean the work can start.

6.2.4 Permit Control

Once the permit has been authorised by the Site Controller it will be taken to permit

control office to be registered and signed by the permit controller where the permit is

given its unique number (section 5).

The Work Permits must be registered as completed (Section 10) with the permit

office at the end of its life which is one day only.

The Work permits are considered records of the Safety Management System

A copy of all Work Permits will be filed using the filing system of the field or

installation.

When Work permits are associated to the occurrence of an incident or accident,

the filing time of the work permit will be the regulated by the accident

investigation procedure, or regulated by the Legal Department.

6.2.5 Gas Testing

If a gas test is required it must be completed before the Task can be started the

authorised gas tester will record the results and sign the permit in (section 6).

6.2.6 Permit Issue

Once the Permit to Work has been approved and registered the Area Authority will

check the worksite and review the Permit with the Performing Authority he will then

sign (section 7a) and issue the permit to the Performing Authority.

6.2.7 Permit Acceptance

The Performing Authority (person carrying out the work) also signs the permit

(Section 7b) after checking all the controls are in place. The Performing Authority

must conduct a Toolbox Talk before the work starts to ensure his team understand

all of the requirements as stated on the permit and record it in the PTW form. All the

team members must sign the reverse side of the permit to confirm the toolbox talk.

The original copy of the work permit must be displayed at the work site controlled by

the Performing Authority.

6.2.8 Continuation of Work (Re-issuing) Work Permits

6.7.11 Closeout Permit to Work ( Completion of Work ) ( Section 9a & 9b )

The Performing Authority, after completing the work described on the Permit,

checks that the site is clean and safe and signs off the Permit.

If for any reason the work is suspended or not completed, details are described.

The Area Authority accepts the hand-back of equipment, verifies that the work

has been completed and that the site is clean and safe, and then signs the

Permit. On the completion of all related Permits, the system is de-isolated.

On completion of the de-isolation, after signing the Certificates and removing all

tags, the Area Authority should sign that all work associated with the Permit is

complete and the system is safe to put back on line.

6.7.12 Registry of Permit Completion ( Section 10 )

This section is used to control the closeout and completion of the permit, all permits

will be registered as closed and kept in the permit office for auditing.

In addition to the above sections, the Permits must also include:

A section for the authorisation of override, inhibition or isolation of critical safety

systems.

A section for recording all related Work Permits.

6.8 Tag SystemIn order to standardise on the type of tags used at the various facilities under CNOOC SES

Ltd control, to avoid confusion by personnel and subcontractors working at different facilities,

all personnel shall follow LOTO flowchart and requirement in Appendix B: Lockout/Tag out

Permit Requirements.

6.9 Depressurising/Draining/Purging

6.9.1 Production Operations, which require Depressurising, Draining and Purging, must be

controlled by the Permit to Work System.

6.9.2 Before breaking any flanges, equipment shall first be depressurised and drained to

atmospheric.

6.9.3 Pressure via the oil contaminated drain system.

6.9.4 It is essential that isolation/purging procedures are developed that include the

checking of valve tightness and that trapping of liquid between valves, or at low

points, is avoided after checking valve tightness.


29/109





Page : 29 of 109



SES Ltd.

6.9.5 Purging of hydrocarbon equipment should be carried out typically by pressurising the

system up to approximately 500 kPa and piston purging at least three times.

6.9.6 Purging, when carried out, must be checked for efficiency at several locations at the

extremes of the system before accepting the system is gas-free.

6.10 Isolation of Equipment for Inspection or Maintenance

The main hazard when working on equipment which is to be isolated is that isolation from a

source of energy or hazardous fluid may be overlooked and the source then activated.

Therefore, the Work Permit will control all work requiring the breaking into of pipe work or

equipment System. Up to date piping and instrumentation diagrams must be used to

construct a written procedure for every piece of equipment that needs to be isolated. The

Planned Isolation Sheet must be used for isolation and attached to the permit.

This procedure must describe; the sequence of isolation, the confirmation of valve tightness,

what connections should be disconnected, the purging and draining requirements, and how

to ensure that all relevant equipment is tagged before starting to open equipment for

installation of blinds/spades. The procedure should include a spade list, clearly defining all

spading points.

Before the isolation is accepted the Responsible Supervisor should verify that the completion

of the isolation is in accordance with that specified on the permit. In the event that the

isolation requires more than one Work Permit then the Permits and associated isolation

records should be formally cross-referenced to eliminate conflict between the different work

activities.

Below is an outline of the minimum mandatory isolation requirements:

6.10.1 Isolationof Electrical Equipment

All electrical isolations of equipment will be carried out by authorised officers and

take the form of a double indemnity break from the source of electrical supply.

This isolation procedure entails:

Identifying, in the field, all relevant equipment/s and their respective Remote

Control Unit/s (RCU).

Once this has been done the RCU's selector switch is hasp-held in the "off"

position.

At the substation, the isolation switch on the motor starter cubicle is switched off

and the cubicle racked out to the isolated position; (if the switchgear does not

allow racking out, then the main fuses shall be withdrawn) and the main cubicle

isolator locked off and "Danger" tagged.


30/109





Page : 30 of 109



SES Ltd.

Verification of the isolation then takes place by trying to start the item of

equipment in the field using the RCU. When isolation is proven, the RCU switch

is hasp-held in the "off" position and "Danger" tagged.

6.10.2 Mechanical Isolations

Isolation of Moving Machinery

Both flow and return currents of the electrical steam, hydraulic or other source of

energy to moving machinery must be isolated. Alternatively, the moving

machinery must be isolated from its drive unit and secured immobile.

Isolation of Process Equipment

To prevent possible inflow of gases, liquids and sometimes solids, isolation in

accordance with the following guidelines is required:

If the unit or system, as a whole, has been shutdown, depressurised and is

toxic gas and Hydrocarbon free, no additional isolation is required to carry

out normal maintenance work. The requirement for positive isolation by a

spade or removed line work for vessel entry is a mandatory requirement.

Refer Appendix 1.

If a system, unit or piece of equipment is to be isolated from gas system

containing gas of ANSI Class 900 rating and above or, liquid system

containing ANSI Class 600 rating and above, then the following minimum

requirements apply:

Minor Work - Double block or double block and bleed is required.

Major Work - Double block or double block and bleed in combination

with spade or blind.

If a system unit or piece of equipment is to be isolated from gas system

containing gas of ANSI Class 600 or below, or LIQUID system containing

ANSI Class 300 or below, then the following minimum requirements apply:

Minor Work - Double block or double block and bleed is required.

Major Work - Double block or double block and bleed in combination

with spade or blind.

If a system unit or piece of equipment is to be isolated from gas system

containing gas of ANSI Class 600 or below, or LIQUID system containing

ANSI Class 300 or below, then the following minimum requirements apply:

Minor Work - Single leak tight closed valve

Major Work - Single leak tight valve plus a spade or blind.


31/109

SES Ltd.

Well Head Isolation

In principle, when working on a well, positive double isolation must be applied.

This may include block valves, tubing plugs, wellhead plug, blow out preventers

or hydrostatic barriers.

A double block and bleed system shall consist of two separate valves with a

bleed connection in between. (Double sealing valves with vents are considered a

single isolation).

When Actuated valves are to be used for isolating purposes for protection of

personnel, all motive power of the valve has to be physically disconnected from

the actuator. Relying on a switch is not adequate.

In the case of hydraulically operated valves, positive isolation of the hydraulic

fluid must be demonstrable.

6.10.3 Deviation to Mandatory Isolation Requirements

Deviations will not normally be acceptable. In "extreme" circumstances where

deviations to the above minimum isolation requirements are necessary and

deemed acceptable, these deviations must be documented as exceptions in the

facilities detailed Permit to Work procedure.

All deviations to the above philosophy must be supported by a detailed

procedure for the isolation, which has been subjected to a job safety analysis.

Deviation to the mandatory isolation requirements and, in particular, the

alternative documented procedures must be approved by the Divisional Manager

responsible for the asset during the execution/operational phase.6.11 Audit ing and Monitor ing

6.11.1 Each Company Asset shall:

Undertake internal audits of the operation of the Risk Assessment process as

part of the Safe System of Work at each site

Maintain an Audit Register, To be in the permit office and maintained by permit

control

Have in place a system for tracking recommendations

Use of a Standard Audit Checklist is recommended

The mandatory frequency of Audit is as follows :

Permit controller 3 permits per week

Supervisor & Head 1 permit per week

Site Managers 1 permit per 2 months

6.11.2 Permit to Work and Risk Assessment audits should be a cross section of ongoing

activities.

6.11.3 PTW audit shall be carried out by one group (choose one supervisor weekly) or one

person basis on weekly, results and recommendation shall be reported after all

monitoring and auditing activities to provide improvements on fault finding; four

audits on weekly basis, at least two audits of form 2 and one audit of form 1.

6.11.4 PTW audit shall refer to Appendix M Monitoring and Audit Check Sheet.

6.11.5 Site Manager shall carry out regular internal reviews of the findings of Permit to Work

and Risk Assessment Audits, to endure that any critical failings in the system, or its

manner of implementation.

6.11.6 The company QHSE Department as part of their annual audit schedule will conduct

PTW and TRA audits.

6.11.7 Such audits should examine a cross section of at least 20 Permit per field.

6.11.8 These audits should examine the auditing completed by installation staff, and

detailed review of Risk Assessments, to check compliance with this procedure.

6.11.9 The result of the annual audit shall be discussed and studied with Management to

see if any change proposals are required.
