Prelude FLNG Project Project Permit To Work Procedure
1. SCOPE
The prime objective of the procedure is to ensure that work is properly planned, controlled,
coordinated and communicated. It is the means of providing written instructions and
authorization to people carrying out potentially hazardous work, ensuring that the safe
working requirements and minimum standards for conducting such tasks on Prelude FLNG
Project Construction, Pre-Commissioning and Commissioning activities until Sail Away are
complied with.
This procedure affects all TECHNIP SAMSUNG CONSORTIUM personnel, SUB-
CONTRACTORS and VENDORS and COMPANY personnel involved in those activities.
TSC personnel and their respective Subcontractors shall not carry out or be required to
perform any activity for which they are not competent or which cannot be performed safely.
This Procedure is a live document which shall be reviewed on a regular basis.
This Procedure supersedes Construction Permit To Work Procedure ref. 2000-120-G000-
GE00-G00000-HX-6180-02016.
The PTW administration is facilitated through a software system that is an electronic work
control system covering the areas of permit application, risk assessment and review of
concurrent activities. However this procedure does not describe the electronic systems use.
Although the PTW administration is by electronic means, final hard / paper copies are used
for written authorization and displayed at work site. Such software system must be
understood by all signatories and in Korean and English as a minimum.
A Permit To Work System is however, only part of an overall work control system which is
dependent on those who raise permits, those who work under them and those who approve
them. An effective safe working environment can only be achieved through systematic
planning, communication, training, checking and implementing control and recovery
measures, worksite monitoring, inspection upon completion of work and audit of the overall
processes.

Prelude FLNG Project Project Permit To Work Procedure
The Permit to Work System shall be adhered to and any noncompliance of the PTW System
or the Shell Life Saving Rules shall result in a disciplinary action being taken. Refer to
Article 15 of the procedure.
A systematic approach to application of the Permit to Work System will involve the following
activities :
Accurately specify the work to be performed, expected duration, plus tools and
equipment to be used
Accurately specify the location where the work will be performed.
Specify all precautions to be taken when preparing the worksite and the safe
working practices while the work is in progress
Complete the preparatory work, ensuring the facility can be safety worked on and
verify that all prescribed personal safety requirements are in place. i.e. gas testing
and equipment isolations.
Give permission for the work to begin by signing the required declarations on the
permit form.
Check job site safety as the work progresses, the validity of permits and
certificates and adherence to the precautions specified.
On completion of the work, check that the job site is left in a safe / tidy condition and sign off
the work permit.
Note: PTW must be job specific with no multiple jobs being specified, That is, One Permit / One Task.
It is vital that all supporting documents to a PTW be correctly cross referenced and that permits are
authorized in relation to other work activities in the same area or on the same equipment.

Prelude FLNG Project Project Permit To Work Procedure
2. PURPOSE
The purpose of this procedure is to:
Clearly define the life cycle of the PTW process and supporting documents to conduct work
in a safe and practicable manner.
Ensure that all personnel work under a single PTW system and are trained in its use.
Specify the Roles and Responsibilities of the various positions within the PTW system.
Identify the types of work that need to be controlled through a PTW. Ensure that the task is fully considered, the sequence of work decided.
Define the applicable work scope Hazards and when additional risk assessments are
required as part of the PTWProcedure.
Specify the minimum Precautions required for the work, based on a Risk Assessment, and
theHierarchy Of Controls.
Define additional PPE which must be used to conduct the task
Specify the preparations and supporting documents required before a PTW can be issued,
the Controls needed to manage the intended work.
Provide a means to assess potential conflicts between different work activities (Concurrent
Work).
Specify period of validity of permits. There will be no shift handover under a single permit, as
the Permit Holder will be different and implications of concurrent activities at day and night
shift have to be re-assessed. Handover in case of continuous activities between Permit
Holders will take place on site verifying jointly the status of progress and completion of the
activity..
All deviations from the PTW Procedure require prior authorization by the PTW Process
Owner and approved way forward must be clearly communicated. Only exception is in
Management of change situations, where the process is well described in the Risk
assessment Procedure, section 4, Management of change.
Ensure the work is formally communicated between all affected parties.
Ensure all personnel involved in the work clearly understand the nature of the work, its
hazards, controls and time restrictions.
Ensure a formal work completion and hand back procedure is used ensuring the affectedplant and equipment is returned to normal operation.
Maintained records of and archive closed permits.

5. APPLICATION
A Permit To Work provides written confirmation that a risk assessment of the specific conditions
affecting the work has been carried out and that the appropriate control measures to protect
personnel and equipment from each of the hazards have been provided. It is a formal agreement
between the Permit Area Authority and those who will carry out the work, that both the risks and the
controls that will mitigate them are understood and that the controls will be fully implemented.
A PTW is required for all tasks listed in Appendix 4. (list to be reviewed on regular basis).
Depending on the risk two different levels of Risk Assessment and Authorization have been
established. Level 1 Risk assessment for the high risk activities and Level 2 Risk assessment which
is contained in the Permit format for the lower risk work. Respectively the permits associated with
Level 1 and Level 2 RA have different authorization level.
This system of Risk Categorization is based on the type of activity and the environment to define
associated risk level to a task. (ref. Appendix 4, Prelude FLNG PTW Scope of application).

Prelude FLNG Project Project Permit To Work Procedure
The PTW itself represents a level 2 risk assessment of the activity and is to be supplemented with
the respective Safe Working Standard for the task. For further detail on the tasks which do not
require Level 1 risk assessment, but still require PTW, refer to Appendix 4.
The Project specific procedures as per the Reference Documents section must be complied with and
the additional requirements associated with each task type factored in the planning, implementation
and communication stages of the PTW process.
For all floating crane, diving and rope access activities the method statements, plans and JSA as
well as the necessary controls and recovery measures shall be agreed with a Company Authorized
Subject Matter Exerts, e.g. appointed Marine Warranty Surveyor for floating crane lifts; Diving
Center of Excellence Aberdeen for diving operations; Rope access SME, etc.
All concurrent activities and interfaces shall be managed by the Area Authorities and final checks and
arrangements agreed at the Permit Coordination Meeting.

workers during such extensions is robust. They must make sure compensation in rest is taking place in
accordance with the local labor law and the regulations.
Permits will not be extended for periods over 14hrs, except for critical test that cannot be interrupted.
Night shift permits should be submitted to the Permit Issuer one whole day prior to the work being
performed.
Where work carries over to the next day, a new PTW will be required and all supporting documents
transferred from the old permit to the new permit prior to authorisation and issue.
For CSU activities in CSU controlled areas, PTW validity can be up to 7 days after Permit Authority
and Area Authority approval.
The old and new PTW documents will be cross referenced in Section 13 of the PTW form and all
supporting documents will be carried forward with their unique number on the new permit. A review of
isolations and supporting documents is conducted to ensure the previous controls remain suitable for
the new permit activities should they differ.

form (ref. Appendix 2, Risk Assessment Template) which must be submitted with the PTW
application as a supporting document and approved by the Area Authority. In some cases a
Jointly (TSC/CPY) revised and signed off Safe Working Standard can also be accepted as
Level 1 Risk Assessment, to acknowledge prior experience / SHI standards for the task.
Tasks requiring PTW and Level 1 or Level 2 Risk Assessment respectively are listed in Appendix 4 of
this document.
The Project specific procedures as listed in the Reference documents are the minimum requirements
for safe execution of the work and must be complied with at all times.

Prelude FLNG Project Project Permit To Work Procedure
10.2 Planning
Safe planning of work involves:
1. Define the task and its operation via a Method Statement
2. Visit the worksite (Permit Requestor/ Permit Holder / Area or Permit Authority / Isolation
Authorities) for field verification. Adjust the method statement and JSA as necessary.
3. Discussing SIMOPS potential at the daily permit Coordination meeting.
10.3 Risk Assessment
The electronic PTW system will automatically designate when a Level 1 risk assessment is required,
by the work type selected at Permit application by the Permit Requestor.
However the auto selection of Hazards and controls by the electronic system is a minimum
requirement only and additional controls must be selected manually by the Permit Requestor and
approved by Permit Authority and the Area Authority depending upon the actual work to be
performed. The additional selection could also be a Level 1 Risk Assessment as per Permit
Requestor, Permit Authority or Area Authority.
Depending the activity and location, several document may be requested by the Permit Issuer :
Method Statement / Detailed Procedure.
Level 1 Risk Assessment; Job Safety Analysis; Safe Working standards
Material Safety Data Sheet (MSDS). PEFS, Marked-up Drawings.
Isolation details.
Crane Inspection Certificate, including load test.
Rigging Certificates.
Competent Person Certificates.
Rigging / Lifting Plan.
Rescue Plan.
Layout plans.

Prelude FLNG Project Project Permit To Work Procedure
The intention of the risk assessment is to reduce the risks to As Low As Reasonably Practicable
(ALARP).
If ALARP cannot be demonstrated, the work should not proceed and alternative methods of work or
additional controls must be applied.
For further detail on risk assessment refer to Project specific procedure, ref. 2000-100-G000-GE00-
G00000-HX-6180-01695.
