1 INTRODUCTION

1.1 Purpose

This Procedure defines PETRONAS Carigali Permit to Work (PTW) system and the process of obtaining work permits including the requirements of obtaining Certificates where required.

1.2 Scope

The requirements defined in this procedure shall be applicable for all hazardous activities carried out at all work locations throughout PETRONAS Carigali global operations, including Contractors and Sub-Contractors engaged for work on Company facilities. Hazardous are activities that have been identified by the Hazards and Effects Management Process as vital to ensure asset integrity, prevent incidents, and/or mitigate adverse HSE effects. Examples of hazardous activities are pigging, production sampling, wireline activities, blasting, welding, etc.

1.3 Permit to Work Requirement

(1) The purpose of PTW system is to ensure that risks associated with work activities are managed to a level that is as low as reasonably practicable (ALARP). The PTW is a written document authorizing persons to carry out the work concerned, warning them of possible hazards and spelling out precautions needed for the job to be done safely.

(2) Listed below is the criteria for the application of PTW

system:

(a) For work carried out on PETRONAS Carigali facilities, PETRONAS Carigali PTW System shall be used;

(b) For work carried out on Contractor’s facilities,

Contractor’s PTW may be used subject to PETRONAS Carigali review and acceptability. When Contractor PTW system is used, PETRONAS Carigali representatives (e.g. OIM, Terminal Manager, CSR, Drilling Supervisor) shall be included as part of the signatory parties for acknowledgement.


WW ALL S 05 002 Rev. 4, July 2013


(3) For workover/infill drilling work carried out on the rig

floor, where Contractor’s PTW is applied, a photocopy of the Contractor’s PTW shall be provided to the OIM for reference.

(4) As a general principle, PTW shall be applied for all

activities which may harmfully affect the personnel, environment, asset or reputation carried out on PETRONAS Carigali facilities. The examples of work that requires PTW among others are as follows:

(a) Hot Work: Any activities or equipment which

may have the potential to generate incentive sparks or other sources of ignition such as welding, flame cutting, grinding, grit/sandblasting, taking of photograph using camera with flash, use of non-intrinsically safe equipment, including opening of junction boxes etc. (potential ignition sources). Refer to sub-section 1.5 for details of hot work requirement in hazardous area;

(b) Cold Work: Any activities or equipment which

does not have the potential to generate sparks such as erecting/dismantling of scaffolding, cold cutting, etc;

(c) Work in confined space i.e. Any enclosed or

partially enclosed space, either above or below ground or deck level, where entry is possible and where accumulation of dust or gases which are flammable or hazardous to health;

Examples of confined space are:

(i) Process vessels and related equipment

(vessel tower skirt and flare stacks), boilers;

(ii) Cooling tower, pipe, storage tanks, other

tanks including pontoon in floating roof tanks;

(iii) Spaces located below ground or deck

level, such as drain pits, sewage pits and associated tunnels, ducts, trenches, wells, shafts, cellars, vaults and unventilated rooms which may be considered confined space under specific circumstances;

(iv) The cargo, ballast or void space onboard

ship; and


WW ALL S 05 002 Rev. 4, July 2013


(v) The support columns/legs/pontoons of

fixed or mobile off-shore installations.

(d) Excavation work of the ground in excess of 150mm (brownfield);

(e) Mechanical lifting activities involving pedestal,

mobile and gantry crane. Lifting using gantry crane in workshop may be carried out without a PTW;

(f) Radiation work involving the handling of

radioactive materials such as radiography works, working in or on equipment containing radioisotopes and removing or servicing radioisotopes;

(g) Closure of any road that may affect the passage

of emergency response vehicles; (h) Electrical works in close proximity to live

conductors/equipment/apparatus,or testing of live voltage conductors;

(i) Diving activities e.g. inspection and

maintenance of subsurface structures, decommissioning of facilities, etc.;

(j) Work with bypass of safety critical equipment

that may jeopardise reliability of process control;

(k) Work requiring energy isolation e.g. physical, electrical or radiation; and

(l) Vehicle entry into PETRONAS Carigali

production facilities. (5) For work which requires Certificates, the Work Permit

shall be supplemented with the required Certificates.

(6) In cases of doubt as to whether a work activity requires a PTW, the PTW requirement shall be complied with if deemed necessary by the Approving Authority.


WW ALL S 05 002 Rev. 4, July 2013


1.4 Hot work in Non-Hydrocarbon Facilities

(1) Non-hydrocarbon facilities are facilities that do not process, store or operate hydrocarbon or any flammable materials in its facilities. Examples of non-hydrocarbon facilities are supply base, office, base camp, fabrication yard, etc.

(2) For hot work at non-HC facilities, the work may be carried out without conducting gas test in view that there is no expected presence of HC in the area.

(3) However, other controls and recovery measures in

making safe the activity shall still be implemented.

1.5 Hot Work in Hazardous Area

(1) Hazardous area are defined as below (based on IP

Model Code of Safe Practice Part 15): Zone 0: Hazardous area in which a

flammable atmosphere is continuously present or present for a long period

Zone 1: Hazardous area in which a flammable atmosphere is likely to occur in normal operation.

Zone 2: Hazardous area in which a flammable atmosphere is not likely to occur in normal operation and if it occurs will exist only for a short period.

Non- classified/ hazardous area

Area where flammable vapours, liquids or gas do not or are not expected to exist

Hierarchy of Hot Work Management

(1) Where possible, hot work should not be carried out in hazardous area.

(2) However, if the hot work is unavoidable, the next preference is to shutdown, depressurise and render hydrocarbon-free. This is to minimize the potential source of fuel that may be ignited by the spark produced from the hot work activities.


WW ALL S 05 002 Rev. 4, July 2013


(3) The requirements for carrying out hot work in hazardous area are as follows:

Zone Limitations

Zone 0 No hot work on live facility shall be allowed, unless the facility is shutdown, depressurise and render hydrocarbon-free.

Zone 1 For open flame hot work e.g. oxy cutting, grinding, etc., the facility shall be shutdown, depressurise and render hydrocarbon-free prior proceeding with hot work.

For blasting, the activity shall only proceed after conversion of instrument gas to instrument air, flanges are wrapped and the area is barricaded

Note: For blasting on process piping where the remaining wall thickness is less than the corrosion allowance, the piping/equipment shall be shutdown prior blasting.

Non-open flame/non-blasting hot work e.g. use of portable hand-held non-intrinsically safe (non-Ex) equipment in Zone 1 area may proceed with implementation of other control and recovery barriers

Zone 2 Open flame hot work on live facility shall only proceed with use of Pressurised Habitat

For blasting, the activity may only proceed after conversion of instrument gas to instrument air, flanges are wrapped and the area is barricaded Note: For blasting on process piping where the remaining wall thickness is less than the corrosion allowance, the piping/equipment shall be shutdown prior blasting.

Non-open flame/non-blasting hot work e.g. use of portable hand-held and mobile non-intrinsically safe (non-Ex) equipment e.g. mobile genset, mobile air-compressor, etc. in Zone 2 area may proceed with implementation of other control and recovery barriers.


WW ALL S 05 002 Rev. 4, July 2013


Non-classified/ hazardous/ safe area

Hot work may be allowed with the conduct of gas testing and implementation of other required control and recovery barriers identified in risk assessment

(4) Additionally, a rigorous risk assessment shall also be

conducted for all hot work activities to identify any other control and recovery barriers to ensure the risks associated with the work is minimised to ALARP.

(5) Regular gas testing at site shall be carried out for any

hot work activity.

Note: Gas test at start of shift or activity only is not

acceptable. AGT has the authority to withdraw a PTW if condition is deem unsafe.

(6) For facilities equipped with fixed gas detectors, the

gas detectors shall not be bypassed during the hot work activities.

(7) For hot work inside confined space, in addition to the

hot work requirement, the confined space entry requirement (e.g. medical declaration, CSE training, etc) shall be fully complied with.

(8) The process to allow the hot work activities to be

conducted on ‘live’ facility is summarized as Figure 1 and 2 below.

(9) For hot work in confined space, the conduct of the

work shall comply with WW ALL S 05 004 PETRONAS Carigali Confined Space Procedure.
