3 Diving Legislation and Guidance

Technip will comply with the following legislation, standards and guidance during diving operations in waters where Australian Commonwealth, State or Territory legislation applies, or applicable legislative requirements in other Asia Pacific regions. However, in Asia Pacific locations where no national regulation exists, Technip will utilise the safe operating standards which it believes are applicable to the region of operation, and as a minimum Technip will comply with the principles stipulated in IMCA International Code of Practice for Offshore Diving (D014).

Diving Project Plans must contain a list of Commonwealth, State and Territory legislation; as well as standards and codes of practice that a diving contractor considers applies to a project (PSL (Diving Safety) Regulation 20). The Technip diving project plan template (Appendix 3) requires this content to be included in Diving Project Plans.

The PSL Act 1967 has been repealed on 1/7/08 and replaced with the Offshore Petroleum Greenshouse Gas Storage Act (OPGGSA) 2006. Since 01/01/05, The Petroleum (Submerged Lands) Act 1967, now known as the OPGGSA, has been administered by the National Offshore Petroleum Safety Authority (NOPSA).

http://ts7apintranet:81/BMS/Published%20Documents/HSE/Procedures/GWP-HSE-223.pdf�




3.1 Australian Commonwealth Legislation

• Offshore Petroleum Greenhouse Gas Storage Act (OPGGSA) 2006.

• Petroleum (Submerged Lands) Act 1967, Commonwealth of Australia – now repealed and replaced by the Offshore Petroleum Act (OPA) 2006.

• Petroleum (Submerged Lands) (Occupational Health and Safety) Regulations 1993

• Petroleum (Submerged Lands) (Management of Safety on Offshore Facilities) Regulations 1996, Commonwealth of Australia.

• Petroleum (Submerged Lands) (Diving Safety) Regulations 2002, Commonwealth of Australia.

• Petroleum (Submerged Lands) (Pipelines) Regulations 2001, Commonwealth of Australia

3.2 Australian State and Territory Legislation

Technip will comply with Australian State and Territory legislation applicable to the region of operation.

For example; relevant Western Australian petroleum legislation includes:

• Petroleum Pipelines Act 1969, and • Petroleum (Submerged Lands) Act 1982.

3.3 Guidance

• AS/NZS 2299.1:1999 Occupational diving operations – Standard operational practice.

• AS 2815 Training and certification of occupational divers. This standard describes the requirements of the Australian Diver Accreditation Scheme (ADAS).

• Guidelines for Complying with The Petroleum (Submerged Lands)(Diving Safety) Regulations 2002

• International Marine Contractors Association (IMCA) Guidance documents. Includes guidance previously issued under the Association of Offshore Diving Contractors (AODC) and the Diving Medical Advisory Committee (DMAC).

• Technip will meet or exceed other Australian and International Standards, as required by legislation.




4 Auditing and Review of the DSMS

4.1 DSMS Review

The DSMS will be reviewed annually as a component of the Technip Business Management System (BMS) Review (conducted at least annually), described in section 14 of the Health, Safety and Environment Manual (MAN-HSE-100) and section 3.0 of the Continual Improvement Procedures (GWP-QA-203).

The broad purpose of Management Reviews is to:

• Review internal and external customer feedback, including feedback from employee involvement

• Review the QHSE objectives • Ensure that QHSE objectives and required results are met • Develop strategies for continual improvement in the way Technip conducts it’s

business • Reveal defects or irregularities • Indicate possible improvements • Check the effectiveness of management at all levels • Identify and eliminate potential problems • Verify that corrective and preventive actions are implemented and effective.

Internal audits are also conducted as part of the BMS review process (see section 4.2 below).

Management system reviews must consider whether a ‘revision’ of the DSMS is necessary. ‘Revision’ is required if circumstances described in PSL (Diving Safety) Regulation 14 arise.

DSMS Revision

For example; ‘revision’ is necessary if a number of minor changes result in the DSMS being significantly different from the latest ‘accepted’ version, or if the diving contractor proposes to make significant changes to the method of operation, procedures or equipment.

A revised DSMS must be resubmitted to the Designated Authority for ‘acceptance’ (refer to section 4.3 below).

4.2 Internal Audit

The DSMS is audited annually, as a component of the overall Technip Business Management System Audit (conducted at least annually), detailed in GWP-HSE-100.

Audits are conducted in accordance with the Internal/External Auditing Procedure

(GWP-QA-201).




The general objectives of internal audits are to:

• Demonstrate the Business Management System is operable as designed and is effective

• Give reasonable assurance Technip worksites are complying with the BMS

• Give reasonable assurance Technip worksites are complying with relevant statutory provisions

• Confirm the organisation is adhering to current QHSE project plans and programmes

• Assist line management in identifying BMS shortcomings, identify solutions and propose improvements

• Ensure that improvements identified and agreed during audit are undertaken in a timely manner.

Processes such as auditing and ‘revision’ of the DSMS enable continual improvement of the DSMS and the reduction of risks to personnel to As Low As Reasonably Practicable (ALARP).

For further information on continual improvement procedures refer to GWP-QA-203 (also section 6.1 below).

4.3 External Audit (Submission of DSMS for ‘Acceptance’)

The DSMS must be initially audited by the Designated Authority (‘DA’), now known as NOPSA, and ‘accepted’ before a contractor can engage in diving activities.

Once ‘accepted’, the DSMS is valid for a period of five years, unless circumstances described in PSL (Diving Safety) Regulation 14 arise, requiring the DSMS to be resubmitted to the Designated Authority for 'acceptance’. In the event that the DSMS is revised for whatever reason and the revision has been accepted by NOPSA, the DSMS will remain valid for a five year period from the date of acceptance of the revision.




5 Diving Project Plans

For each project involving diving operations in Australian Waters, a specific Diving Project Plan will be developed and submitted to the operator (or to NOPSA if there is no operator) for approval.

PSL (Diving Safety) Regulation 20 describes the required content of Diving Project Plans. To ensure compliance with this regulation, all Diving Project Plans will be prepared in accordance with the template in Appendix 3.

6 Diver / Employee Involvement

Regulation 22 of the PSL (Diving Safety) Regulations describes requirements for the involvement of divers and other employees in the development and maintenance of the DSMS and Diving Project Plans.

When submitting the DSMS to NOPSA for acceptance, the diving contractor must set out in writing details of the consultation process that has taken place, including submissions made during the consultation process, and any changes that have been made to the DSMS as a result of the consultation.

Refer to Appendix 5 for a general guide to locating evidence of diver/employee involvement in Technip’s DSMS/Diving Project Plan development and revision.

The following sections outline the various types of diver/employee involvement in DSMS/Diving Project Plan development and revision.

6.1 DSMS Development and Revision

DSMS Working Group meetings – These meetings typically involve diving personnel, such as supervisors, divers and management representatives. The meetings consider such issues as the regionalising of the Group Diving Manual, and the development/revision of other DSMS components.

Inter Discipline Checks (IDC). These may include documents checked by employees of Technip as well as other members of Technip’s Diving Safety Network (DSN) outside Australia. For example; the Technip Group Diving Manual is produced by the DSN and is reviewed by personnel from throughout Technip’s worldwide diving operations.

DSMS Review – As mentioned in section 4.0, the DSMS is reviewed and audited annually. The meetings held for the review are attended by suitably qualified personnel, which typically include divers, supervisors and relevant managers.

Audits – The DSMS is audited and reviewed annually (refer to section 4.0).

Systems Improvement – Employees are able to make suggestions for improvement of the Group Diving Manual or other DSMS components at any time. This is achieved by completing a Systems Improvement form (See Continual Improvement Procedure of GWP-QA-203).




Systems improvement suggestions are encouraged to assist with continual improvement of the diving manual, general procedures and the DSMS as a whole.

In order to comply with PSL (Diving Safety) Regulation 22, (employee involvement in DSMS development) the current Technip DSMS submitted to NOPSA contains evidence of employee involvement in the revision of the DSMS (see Appendix 6).

Current DSMS Submission

6.2 Diving Project Plan Development and Revision

Diving Project Plans are subject to standard technical document review procedures, according to GWP-ENG-201, the Technip Document Control Procedure. This process requires the involvement of suitably qualified personnel during Inter Discipline Checks. Details of the personnel involved in the review process are summarised on the front of each document and in the electronic database known as the PDB.

With regard to projects, personnel are involved in: • Procedural reviews (GWP-ENG-201) • Hazard Identification Studies (HAZIDS) – According to GWP-PRJ-207, the

Technip Risk Management Procedure • Constructability Reviews (GWP-ENG-203 – Technip’s Internal & External Design

Control Procedure & GWP-PRJ-207) • Job Hazard Analysis (JHA) and Toolbox Safety Meetings (GWP-PRJ-207).

In accordance with Regulation 22, future Diving Project Plans submitted to the Operator (or to NOPSA in the absence of an Operator) shall include a selection of evidence demonstrating diver & employee involvement in the development of the plan.

Diving Project Plans

In addition, the Technip Diving Project Plan template (Appendix 3) requires Diving Project Plans to contain evidence of diver/employee involvement.

8.5 Permit to Work System

The Vessel Business Management System (BMS) Permit to Work procedure (TBA) will be utilised on board the vessel as per the Vessel Safety Case (TBA). When in proximity with other facilities the COMPANY’S SIMOPs Plan outlines which PTW System takes precedence. Countersigning of the Permit to Work will be required.

The PTW ensures that:

All potentially hazardous work activities have the appropriate authority to proceed;

The responsibilities and spheres of influence of the accountable persons are clearly established;

The lines of authority are clearly defined and maintained throughout the execution of the work;

All plant and equipment associated with the work has been made safe to ensure the safety of those doing the work and the safety of others in the vicinity;

The work environment is free from dangerous concentrations of gas, vapours or fumes;

Concurrent activities in the vicinity are controlled and coordinated to ensure safe operations, and;

Set out clearly the communications, monitoring requirements and sequencing of activities.

11.0 RISK MANAGMENT

11.1 Project Risk Management All tasks to be performed during the installation works will be subject to various Risk Management activities through the preparation planning and execution of the task. These activities aim to identify hazards beyond the usual diving hazards recognised in the Diving Safety Manuals and are specific to the project. CONTRACTOR’s risk management activities are summarised below.

Description Project Phase Purpose Personnel Involved

Risk and Opportunities Review

Tender, Post Award, Pre Constructability review

Exploit the projects strength and opportunities and overcome the projects weaknesses.

PM, CM, HSEM, Responsible Engineers, Topic Specialists

Constructability Review

Early development of design

An early review of preliminary engineering procedures to ensure that they adequately address safe construction, installation, and operational issues along with any technical difficulties associated with the project programme.

PM, CM, HSEM, OCM (Diving), Responsible Engineers, Relevant Subcontractor, COMPANY

Hazard Identification (HAZID)

Procedures usually at Rev B

To identify and quantify foreseeable risks arising from fabrication, mobilisation, installation, commissioning and operation of project equipment. Control measures are agreed and recorded for tracking through to close out.

PM, CM, HSEM, OCM (Diving), Responsible Engineers, Relevant Subcontractor, COMPANY, Diving Supervisor, Diver

Job Hazard Analysis (JHA)

On-site To manage residual risks either not foreseen in the HAZID workshop or which a HAZID identified as requiring a JHA.

OCM, Site Supervisors & their respective teams.

11.2 Constructability Review Constructability reviews are held early in the engineering phase, prior to Revision A of procedures for a specific scope of work. The review covers all elements of the scope including engineering, fabrication, load out, installation, commissioning and, where appropriate, operation. The purpose of Constructability reviews is to provide early feedback to the Responsible Engineers on design flaws, safety issues, installation and operability concerns. No attempt is made to quantify risk in this review.

The output from the Constructability review is entered into the project specific Constructability Review Report subject for internal document control and issued for COMPANY Review and approval. The PM assigns responsibilities and deadlines for completion of corrective action. The RE is responsible for documenting the way in which the action has been closed out.

Constructability Reviews are attended by representatives from CONTRACTOR, and COMPANY. Diving personnel are also invited to participate where diving activities are expected to occur.

DIVING PROJECT PLAN



11.3 HAZID Workshop The HAZID workshop is scheduled when a work procedure has been issued at Revision B. The purpose of the HAZID workshop is for the Project Management Team (including COMPANY representatives) to perform a detailed review of the procedure to identify hazards arising from the scope of work, quantify risk against a Risk Matrix and agree on control measures. External expertise is solicited where deemed necessary. Diving personnel are required to participate in HAZIDs on procedures where diving activities will occur to provide hands on expertise.

The outcome from the workshop will be entered into the project specific Risk Register. The Project Manager reviews the hazard, allocates a champion and sets a deadline for completion of the corrective action. The allocated Champion is responsible for close out of each item. Close out shall be recorded on a HAZID Action Close Out sheet. The Closed out HAZID form will be attached to final work procedure for COMPANY approval and the HAZID register closed out by CONTRACTOR.

All HAZID items must be closed out prior to the work related to the procedure commencing. Some HAZID items may not be closed out at the primary prevention stage, site actions will be required to ensure risks are mitigated.

11.4 Job Hazard Analysis Despite efforts to reduce risk during the engineering phase of a project, there will be a degree of residual risk associated with each task performed. It is necessary to manage this risk at the work site.

The primary tool for risk management at the work site is the JHA which will be supplemented by the Step Back 5 x 5 programme, these are described in depth in the HSE Management Plan (TBA). JHAs developed for each operation will be kept on file and an electronic register will be available for reference throughout the project. Where unforeseen hazards are identified during diving operations, the JHA will be reviewed to reflect the hazard and measures taken to mitigate those risks.

Where residual risk remains PPE may be used as a last resort to reduce risk to ALARP.

11.5 Management of Change

11.5.1 Offshore Phase Where it is necessary to deviate from the procedure the Offshore Management of Change Procedure (GWP-PRJ-218) will be implemented. Each deviation associated with that task will be assessed to determine the effect of the change; this process is described in, Offshore Management of Change Procedure.

11.5.2 Onshore Phase The CONTRACTOR Onshore Management of Change Procedure (GWP-PRJ-211) is used, where a change is required during the engineering phase. Internal changes are initiated by the Responsible Engineer and recorded. The proposed change will be reviewed by discipline Lead Engineers and specialists for impact on areas within their responsibility.

DIVING PROJECT PLAN



12.0 INCIDENT REPORTING AND INVESTIGATION Any injury, near miss, or hazard shall be verbally reported to the OCM, Vessel Master and COMPANY RE upon occurrence, in accordance with CONTRACTOR Incident Investigation and Reporting Procedure (GWP-HSE-207). The responsibility for initial reporting of an incident rests with the individual and immediate supervisor.

Following an incident the COMPANY RE shall be informed immediately and a copy of the CONTRACTOR Initial Incident Report presented to the COMPANY RE as soon as completed. ‘Immediate’ means after due consideration to treating the injured person and securing the site, but should normally be within one hour of the incident.

Corrective actions shall be tracked and closed out in a time frame acceptable to COMPANY and CONTRACTOR management.

In accordance with the requirements of the Incident Investigation and Reporting Procedure GWP-HSE-207, the immediate Supervisor will ensure the report form is properly completed and immediately copied to:

Project Manager (onshore), who will liaise with the COMPANY Project Manager and in turn with the appropriate Regulatory Authority as necessary

Project HSE Manager

QHSE Manager (onshore)

COMPANY Representative (site or located in COMPANY office)

File project office Incident reports will be monitored by the Project HSE Co-ordinator and evaluated for adverse trends; corrective steps will be taken to prevent reoccurrences as necessary.

12.1 Legislative Requirements For any incident occurring onboard the DSV, CONTRACTOR as the nominated operator, shall comply with the regulatory reporting as per clause 41 of Schedule 7 of the PSLA.

The requirement for monthly reporting is described in the regulations made under the Petroleum (Submerged Lands) Act 1967. The relevant regulation is in:

Petroleum (Submerged Lands) (Management of Safety on Offshore Facilities) Regulations 1996, Part 5, Regulation 46, Sub-Regulation 4.

(4) As soon as practicable, but not later than 15 days after the end of each month, the operator of a facility must submit, to NOPSA, a written report, for that month. This shall be completed by CONTRACTOR QHSE Manager.

12.2 Investigation The direct Supervisor of the location where an incident occurred will be responsible for carrying out the investigation, with the assistance of the Offshore HSE Coordinator. A member of the Vessel Safety Committee may be asked to participate. All investigations will be performed as per CONTRACTOR Incident Investigation and Reporting Procedure (GWP-HSE-207), which provides guidance to the personnel required to investigate incidents of varying severity.

DIVING PROJECT PLAN



13.0 MONITORING

13.1 Records Diving Operations records will be kept in accordance with Section 32 Petroleum (Submerged Lands) (Diving Safety) Regulations 2002.

13.2 Continual Improvement A fundamental element of any Risk Management process is to ensure that experience is collated and disseminated to improve methods of work and avoid repetition of mistakes.

The following processes are used to provide this feedback:

ORCA II Refer to HSE Management Plan, (TBA)

Hazard Observations Refer to HSE Management Plan, (TBA)

Systems Improvements where employees are encouraged to formally submit suggestions for improving a management system or process

Lessons learnt from incidents

14.0 PROJECT CLOSE OUT/LESSONS LEARNED (REFER TO GWP-PRJ-215) CONSULTATION WITH DIVERS AND EMPLOYEES

CONTRACTOR have an obligation to ensure that in developing this Diving Project Plan, there is effective consultation and participation of diving personnel and other employees who will, or may be working on the project. This will be achieved through the following means:

Consultation with diving personnel during the development of the plan,

Diving personnel will be invited to review the plan during the IDC process of this document at Revision A, and;

Diving personnel will be invited to attend and will participate in each HAZID that involves diving activities

DIVING PROJECT PLAN




1.0 INTRODUCTION

1.1 Purpose

This Diving Project Plan has been developed to describe the manner in which the CONTRACTOR diving scope of work for the Montara Field Development Project will be conducted. All diving works will be performed from the Dive Support Vessel (DSV) Venturer.

Technip UK Limited (TUK) is the owner of the Venturer and as such all diving operations will be conducted in strict accordance to Technip Oceania Pty. Ltd. Diving Safety Management System (DSMS), CONTRACTOR Doc Number DSMS 100 and DSMS 200 and International Marine Contractors Association (IMCA) industry guidance, specifically to IMCA D014 Code of Practice for Offshore Diving and IMCA D010 Diving Operations from Vessels Operating in Dynamically Positioned Mode.

This Diving Project Plan is prepared in accordance with the requirement of Part 3 of the Petroleum (Submerged Lands) (Diving Safety) Regulations 2002 and supplements the DSMS which was accepted by NOPSA 6th October 2008 (refer to NOPSA website: www.nopsa.gov.au). The Diving Project Plan does not replace CONTRACTORS DSMS but will be used in conjunction with the work procedures that have been developed for each phase of the operation. For project specific requirements of the particular diving tasks refer to the operational procedures listed in Section Error! Reference source not found..

The Diving Project Plan (DPP) also provides contingency procedures for any foreseeable emergency and demonstrates that the risks associated with the intended diving project will be carried out in such a way that ensures risks to the health and safety of personnel involved and to the environment are reduced to a level which is as low as is reasonably practicable (ALARP).

A summary of the HSE aspects of the diving activities is described in Section 8.0.

A full list of hazards for the Montara Project Development will be found in the Project HAZID Report (JA014704-101-PRO-7215-0001).

1.2 Revision of the Plan

The DPP will be revised if / when:

Holds are lifted

Modification / changes, significant increase / decrease in the overall level of risk to a diving operation

COMPANY proposes to undertake or permit a modification of the project that might influence significantly the level of specific risks to a diving operation or the ranking of risk contributors.


DIVING PROJECT PLAN




1.3 Field Description

The Montara Development Project (MDP) incorporates the Montara, Swift and Skua fields. The Montara field is located approximately 690km West of Darwin in the Ashmore Cartier permit area of the Timor Sea within the AC/RL3 retention lease. The water depth throughout the fields varies between 76 and 82m. The Swift and Skua fields are approximately 17km and 26km respectively north-northwest from the Montara field. PTTEP Australasia (Ashmore Cartier) Pty Ltd (PTTEP AA), the Operator, intends to develop these fields and operate the developed facilities for commercial production of the oil reserves.

Field Location of Montara Development Project

The proposed development at Montara comprises an unmanned minimal facility wellhead platform (WHP) with four (4) horizontal production wells; a single gas re-injection well; a Floating Production Storage and Offloading vessel (Montara Venture FPSO) and associated mooring system; flowlines, risers and control umbilical connecting the WHP to the FPSO; FPSO located production facilities to separate the produced oil, water and gas; and an offloading system designed for offloading processed crude to stern moored shuttle tankers. The produced gas is used for fuel gas on the FPSO and for gas lift on all development wells, with the balance reinjected into the Montara formation at the WHP.

The development at Swift comprises initially two (2) subsea wells (Swift North 1 and Swallow 1) tied back to a subsea manifold via rigid flowlines, connecting to approximately 18 km of 14” rigid flowline back to the WHP. Gas lift for the subsea wells is supplied from

DIVING PROJECT PLAN




5.0 DIVING OPERATIONS Prior to work commencing, all physical and system interfaces will be reviewed to ensure diving operations will be carried out in accordance with the dive plans and procedures. Agreed protocols are to be put in place to ensure all interfaces have been addressed.

A pre-dive briefing will be conducted by the Dive Supervisor and Responsible Engineer prior to the commencement of all diving operations. The briefing will ensure all personnel / divers involved with the planned tasks are familiar with the procedure and required equipment. A dedicated dive plan will be generated and distributed to relevant personnel prior to commencement of dive operations. The Dive Supervisor will direct all operations and only deploy the divers when equipment and the work site are in a safe condition. Communications between divers and dive control are will be checked to ensure they are functioning correctly at all times.

Divers will at all times be in a safe location during over boarding and deployment of equipment (e.g. PLET, rigid spools, concrete mattresses) and shall not proceed to the worksite until equipment has stopped at approximately 5m to 10m off the seabed. Weighted tag lines will be attached to all deployed loads to aid divers during final positioning and land-out onto the seabed. Divers will avoid going underneath materials and equipment, maintain clear communications with the Dive Supervisor and maintain good umbilical management techniques. All vessel and crane movements shall be in a controlled and coordinated manner and will be directed by the Diving Supervisor.

All work scopes involving the use of air bags shall be performed in accordance with IMCA D 016 Rev 3 Underwater Air Lift Bags guidance document.

5.1 Description of Diving Team & Methodology

5.1.1 Saturation Diving From the DSV The DSV has capacity for continuous single bell saturation diving operations, (Refer to Saturation Diving Manual for the vessel and dive system specifications). It is expected that diving operations will be performed for approx 100+ days, therefore, as a minimum, a back to back rotation of the dive team is required (28 days each seal to seal). For the duration of diving works from the DSV, three dive teams, each with three divers, are planned to be available in saturation.

The DSV will be equipped with one WROV which will be used to assist / support diving operations, including emergency situations if required.

During saturation diving operations at least one man will remain as bellman at all times. There may be occasions when only one diver is required to lock out (e.g. during light work tasks over a short period). One man will remain as bellman and Diver 2 will be on standby to lock out in an emergency or assist Diver 1 as required.

In accordance with the CONTRACTOR DSMS the bell-runs will be limited to a maximum time of eight hours (seal to seal). In addition the maximum time working for each diver will be limited to six hours. There is an allowance to increase this time by 30 minutes if all parties agree. This limitation will be applied to the time the diver is out of the bell.

Prior to undertaking work on any of the trees, the relevant isolations will be confirmed, complete with isolation certificate which will be issued to the DSV. Corresponding PTW and Permission to Dive requests will be raised on the DSV. Refer to COMPANY Montara Development SIMOPs Plan for applicability and precedence of PTW’s for use. Countersigning of work permits will be required.


DIVING PROJECT PLAN




5.1.2 Composition of Dive Team (Minimum) – Saturation

The following diving specific personnel will be engaged on the project for 24 hour operation:

1 x Diving Superintendent (IMCA/ADAS approved)

3 x Diving Supervisors (IMCA/ADAS approved)

4 x Life Support Technicians (IMCA Certified)

9 x Saturation Divers qualified in accordance to ADAS requirements

4 x Diving System Maintenance Technicians (CONTRACTOR approved)

5 x Deck divers (qualified in accordance to ADAS requirements)

Note: In addition to the diving personnel other disciplines i.e. rigging teams, ROV will be on site to assist/support the dive team.

5.1.3 Surface Supplied Air Diving From the DSV The Venturer will support a third party supplied surface diving system with a diving decompression chamber used for emergency/treatment surface decompression using oxygen (SurDO2) decompression. The surface diving equipment and control panel is rated to – 50m msl with deployment and recovery of the divers by LARS.

Diving works will be limited to the top of the STP buoy and will be conducted intermittently through-out the campaign.

5.1.4 Composition of Dive Team (Minimum) – Air

Air range diving operations will be conducted from an air diving launch station situated on the Venturer starboard side. The project work scope indicates that most of the air range diving support work will be conducted at around the -15msl. During the planned air diving operations the surface deployed air divers umbilicals may require both passive and active in water tending.

The following diving specific personnel will be engaged on the project for 12 hour operation:

1 x Diving Supervisor (IMCA/ADAS approved)

5 x Air Divers (qualified in accordance to ADAS requirements)

Control of divers’ umbilicals will be conducted in full compliance to IMCA guidance. IMCA D010 Diving Operations from Vessels Operating in Dynamically Positioned Mode.

5.2 Site Preparation Prior to deploying the bell a WROV survey of the worksite shall be carried out, checking for any anomalies or potential hazards. If any hazards are identified a Risk Assessment will be performed to ensure all risk is brought to ALARP before diving operations commence. Seabed rectification / preparation by divers may be required in the form of dredging or installation of sand bags. When handling sandbags an assessment on manual handling will be carried out.


DIVING PROJECT PLAN




5.3 Diver Umbilical Management Where an excursion is planned such that the diver could be brought within range of physical hazards such as vessel thrusters, propellers and water intakes, then the divers umbilical must be physically restrained to prevent it coming within five metres of such hazards. The umbilical management and umbilical length calculations are to be in accordance with the CONTRACTOR DSMS Saturation Diving Manual and in accordance to umbilical management charts located on the Venturer (Refer to Appendix A).

To ensure that diver umbilicals remain free from obstruction and that safe access / egress to the work site is established and maintained, a combination of some or all the following measures will be taken:

Debris or obstructions in the escape path is to be cleared prior to operations;

Where obstructions are not able to be moved, they shall be protected to facilitate safe umbilical movement over the obstruction;

Umbilicals to be negatively buoyant for saturation diving and neutrally buoyant for air diving;

Umbilicals to be marked to allow bellman / tender to monitor length deployed;

Bellman / tender to monitor umbilicals of (both) diver(s);

ROV to provide illumination of work site.

Bellman / tender shall take up all umbilical slack;

Diver shall be aware of where his umbilical leads at all times.

Prior to commencing operations, a JHA will be performed by the diving team. All personnel will be briefed on the hazards associated with the nature of operations, duration of dive and recovery and the importance of umbilical management.

5.4 Loss of Gas Supply to Saturation Divers In the event of loss of gas supply, divers will be wearing bail-out bottles with sufficient capacity to provide the divers 1 minute of breathing gas for every 10 metres of deployed umbilical @ 42.5 litres/minute. If this situation occurs, divers will go immediately onto bailout and return to the bell. If breathing gas is not restored on arrival at the bell, first diver back to go inside the bell and quickly clear the trunk allowing the second diver to enter the bell and remove diving helmet. The Supervisor and bellman will immediately investigate the loss of breathing gas and if required recover the bell.

Refer to the Technip Group Diving Manual.

5.5 Supervision The Diving Superintendent is responsible for and maintains overriding control over all safety aspects of the diving operations.

The supervision of the diving operation on the DSV will include:

1 x Diving Superintendent (A qualified Diving Supervisor)

3 x Diving Supervisors

For saturation diving, one Supervisor will be assigned to the midday to midnight shift and one Diving Supervisor to the midnight to midday shift. The Diving Superintendent and the


DIVING PROJECT PLAN




third Diving Supervisor will operate on a split-shift system so that at any-one-time, there will always be two supervisors on shift to provide cover for meal and comfort breaks, or when the work demands two supervisors.

For air diving one Supervisor will be assigned per 12 hour shift. The Diving Superintendent and/or the third Diving Supervisor will be available to relieve the air dive Supervisor as and when required.

Each Diving Supervisor will be responsible for providing a comprehensive handover when being relieved, which will be recorded in the diving operations record.

Copies of these regulations and guidance will be available on site – the contents of which the Supervisors are to make themselves fully familiar with. Diving supervisors will be appointed in writing by CONTRACTOR.

5.6 Diver and Dive Supervisor Briefings All diving personnel will be familiar with the operations and required tooling to be used during the implementation of the procedure. A dive briefing with the diving team is held prior to all dives to ensure all parties are aware of any specific hazards or operational requirements associated with the dive. All necessary JHAs will be developed / reviewed during the brief. Detailed installation procedures will be provided in advance to dive teams as well as individual dive task plans specific to the task at hand.

5.7 Dive Plans Prior to the divers entering the bell / basket and commencing any diving, a project specific Dive Plan will be issued to the diving team identifying all the relevant tasks to be performed during the proposed dive. A summary of the procedure to be implemented along with support drawings and visual aids will be supplied outlining all the requirements of the proposed work scope. A pre-dive meeting will be held with the Responsible Engineer, Diving Supervisors and Divers to discuss and explain the Dive Plan. This meeting provides the Divers with details of risks associated with the work about to be performed. The Engineer will use this opportunity to address concerns and questions raised by the Divers/Supervisors.

5.8 Decompression On work-scope completion saturation decompression and bend watch of the divers is expected to be undertaken during vessel transit to the demobilisation location or as directed / agreed by the Project Manager and onboard Management Team. If saturation decompression and bend watch are undertaken during transit to de-mobilisation site, the duty HSV, with the LSP package mounted onboard, will accompany the Venturer until completion of the bend watch. During bend watch a dedicated support team will be available to assist divers should the need for recompression/dysbaric illness treatment be required. Only upon successful completion of bend watch will the LSP be back loaded onto the Venturer and the HSV released.

Decompression for air diving works will be conducted as specified in the Technip Group Diving Manual (DSMS 201). A twin lock decompression chamber will be located on board the Venturer for use by the air diving team during emergency/treatment decompression.

5.9 Diving System and Associated Support Facilities

The vessel is fitted with a DnV classified Saturation Diving System, operable to a depth of 300 metres. The saturation system consists of a 16 man diving chamber complex and single three men rated diving bell which is launched through a centrally positioned bell moon pool. The bell is guided through the moon-pool by a cursor running on vertical rails,


DIVING PROJECT PLAN




and the moon-pool is fitted with baffles to dampen surge. The central dive control room controls and monitors bell launch and recovery operations and there are direct communications to all other key locations within the vessel. Saturation control centre contains all controls, monitors and communications systems for the complete chamber complex. A direct phone link to the Bridge (OCM position), and closed circuit TV system, ensure full communications during diving operations.

The Venturer will support a third party supplied surface diving system with a diving decompression chamber used for emergency/treatment surface decompression using oxygen (SurDO2) decompression. The surface diving equipment and control panel is rated to – 50m msl with deployment and recovery of the divers by LARS.

The Venturer is also equipped with a WROV system which will be used to support diving operations and which may be used to assist divers in an emergency situation.

The Saturation Diving System is complete with a self propelled Hyperbaric Rescue Lifeboat (HRL)

5.10 Hyperbaric Rescue Lifeboat (HRL)

The self propelled HRL is equipped to evacuate 16 divers under pressure, plus 3 crew in case of an emergency and to provide autonomous life support for 72 hours whilst awaiting rescue.

In an emergency situation requiring the HRL to be launched, three members of the Venturer crew are used to man the vessel. These positions consist of the off shift Life Support Supervisor (LSS) or Life Support Technician (LST), Mechanical Dive Technician and a Coxswain who is one of the Venturer bridge officers. All these personnel will be familiar with the HRL and its operating procedures with regular drills conducted onboard the Venturer to reinforce understanding of roles and promote familiarisation of the equipment.

5.10.1 Life Support Package (LSP) The HSV shall stay within an agreed radius of the Venturer during operations in the Montara field. In the event of an emergency involving divers in saturation, the HSV will accompany the Venturer if the DSV or HRL is required to leave the Montara filed. The LSP will be stored either on a designated HSV.

The Venturer Life Support Package consists of the following housed in a 20ft half height container:

1 x 20’ half height container (containing gas quads) L=4.57 x W=2.50 x H=2.05 m gross weight 6.8 Te

5.10.2 Hyperbaric Reception Facility

Operation of the HRF has been subcontracted to Neptune Diving Services. The HRF will be established in Darwin.

The HRF living chambers are outfitted with bunks for 12 persons with BIBS for all occupants

The above is maintained / certified in compliance to legislative, CONTRACTOR and industry standards.

The system will be assembled, commissioned and tested prior to the commencement of diving operations.

The HRF shall be fully functional and maintained in readiness to receive the HRL and transfer divers from the pressurised craft into the HRF system i.e. recovery and lock-on of the Venturer HRL.

During diving operations, the HRF will be subjected to daily security checks and weekly maintenance and function testing. Power and water supplies will be connected at the time of commissioning and remain connected throughout the period the HRF is set-up in Darwin.

In addition CONTRACTOR will provide a dedicated logistics coordinator in the local area to provide support to the project, including the HRF team. Full equipment specification and operating procedures are contained in document: GWP-HSE-203 Hyperbaric Evacuation Guidelines.


DIVING PROJECT PLAN




6.0 EXPOSURE TO HYDROCARBONS Isolation requirements during rigid spool tie-in scope of work are to be in accordance with IMCA D 006 Diving Operations in the Vicinity of Pipelines, Technip UK Isolation and Intervention Guidelines for Diver Access to Subsea Systems Doc No ABSS.Q/007 and the Oil Industry Advisory Committee “The Safe Isolation of Plant and equipment” ref. 3 for isolation requirements.

In the unlikely event of a hydrocarbon release during rigid spool tie-in to the trees, the primary control measure to avert contamination is to prevent any volatile compound entering the bell. The pipeline will be filled with treated seawater however; the possibility of bell contamination by hydrocarbons cannot be discounted during spool tie-in to the trees. Special PPE maybe be worn by the divers when connecting the spools to the trees. Should a release occur, divers will remove and dispose of this PPE prior to entering the bell. During tie-in operations, the bell will be positioned ‘upstream’ of the worksite and bell monitoring equipment will be used to detect contamination of the bell atmosphere.

Refer to the Technip Group Diving Manual DSMS-201.

Appendix C contains the Diving in Areas of Potential Contamination Consideration Checklist.


DIVING PROJECT PLAN




7.0 PHYSICAL ENVIRONMENT

7.1 Climate Based upon information taken from COMPANY documentation:

The climate of Northern Australia, the Timor Sea, shows two distinct seasons, “winter” or “dry” from April to September and “summer” or “wet” from October to March, with very rapid transition between the two main seasons. This is a result of two major atmospheric pressure systems, the subtropical ridge of high pressure cells (high or anticyclones) and the broad tropical low pressure region called the monsoon trough.

Note: The DSV Venturer’s scope of work will be carried out predominantly during the Winter Season (‘dry season’).

The subtropical highs move from west to east across southern Australia in winter and further south in summer, usually separated by low pressure troughs or cold fronts. The highs provide the driving force behind the southeast trade winds which dominate northern Australia’s weather during winter months

The monsoon trough or inter-tropical convergence zone is a broad area of low atmospheric pressure running east-west through the tropics in the summer months. It follows the sun, shifting north and south between the hemispheres with the seasons.

In the southern hemisphere it is the meeting place of the dry east to southeast winds generated by the subtropical highs, and the moisture-laden north-westerly monsoon winds. During the summer it lies for lengthy periods over north Australia, and is the source of much rainfall.

7.2 Wind

The “dry” season (April to September) is characterised by steady northeast to southeast winds of 5 to 12 m/s driven by the South East Trade Winds over Australia. The prevailing south-easterlies bring predominantly fine conditions throughout the North of Australia.

The “wet” season (October to March) is the period of the predominant North West Monsoon. It is characterise by northwest to southwest winds of 5 m/s for periods of 5-10 days with surges in the airflow of 8-12 m/s for periods of 1-3 days.

7.3 Currents and Tides

The tides of the Timor Sea are unusual, as they retain substantial tidal amplitude at relatively large distances from the coastline. Both the semidiurnal (~24hr period) and diurnal (~12hr period) tides appear to travel north-eastwards in the deep water leading to the Timor Trough, prior to propagation eastwards and southwards across the wide continental shelf.

Tides are predominately diurnal (two highs and two lows each day) with a diurnal inequality (difference between successive highs and successive lows). The dominance of diurnal tides persists even at neap tides.

The spring tide range is about 3.6m at Montara and Mean Sea Level (MSL) is about 2.2m (above local LAT).


DIVING PROJECT PLAN




7.4 Waves

The waves expected during the installation phase are typically a swell from the southwest at 1.0 to 1.5m significant wave height and a wind wave from the east of 1.0m significant wave height.

The sea state at any particular exposed ocean location arises from a combination of remotely generated swell and locally generated sea.

Swell is generated by distant storms, and propagates to the region of interest, gradually diminishing due to frictional alternations.

Sea refers to the shorter period waves generated by local winds in the immediate vicinity of a particular site. The sea can be affected by the strength and duration of wind forcing, and by the available distance (fetch) over which the generating wind blows.

The sea state of the Timor Sea comprises contributions from:

Indian Ocean swell

Winter easterly swell

Westerly Monsoonal swell

Tropical cyclone swell

Local wind generated sea

Where sufficient fetch is available (at least 200km), the synoptic easterlies which prevail overall the Timor Sea , may generate an easterly or north-easterly swell of 6 to 10 second period.

7.5 Cyclones

The Montara field lies in an area under the influence of the NW and SE monsoons (SE trade winds) and the tropical cyclones that affect the area particularly during the summer and autumn.

Tropical cyclones can develop off the coast in the ‘wet’ season (October – March), usually forming within an active monsoon trough. Heavy rain and strong winds, sometimes of destructive strength, can be experienced along the coast within several hundred kilometres of the centre of a cyclone.

Extreme winds can occur throughout the year: Easterly gales in winter (dry season – April – September) and tropical cyclones in the cyclone season from November to April. The majority of cyclones move down the Northwest coast between 40 and 400 km offshore. Cyclone activity for the area has been estimated at an average 10.7 days per year.

7.6 Sedimentology Extract from the Montara Development Installation and Commissioning Environment Plan

“Results from seabed sampling indicate that the unconsolidated sediments are fine to coarse carbonate sands. The sediments appear to be coarser closer to the areas of significant relief and at the base of shallow depressions. The sub-bottom profilers did not achieve significant penetration into the calcarenite material, indicating that the upper surface of the calcarenite is relatively hard.”


DIVING PROJECT PLAN




7.7 Water Temperature

Max sea surface temperatures may reach 31oC in summer and drop to approximately 26oC during late winter.

The difference between near-surface and near bottom temperatures ranges from approximately 7oC in summer to approximately 3oC in winter.

11.2 Constructability Review Constructability reviews are held early in the engineering phase, prior to Revision A of procedures for a specific scope of work. The review covers all elements of the scope including engineering, fabrication, load out, installation, commissioning and, where appropriate, operation. The purpose of Constructability reviews is to provide early feedback to the Responsible Engineers on design flaws, safety issues, installation and operability concerns. No attempt is made to quantify risk in this review.

The output from the Constructability review is entered into the project specific Constructability Review Report subject for internal document control and issued for COMPANY Review and approval. The PM assigns responsibilities and deadlines for completion of corrective action. The RE is responsible for documenting the way in which the action has been closed out.

Constructability Reviews are attended by representatives from CONTRACTOR, and COMPANY. Diving personnel are also invited to participate where diving activities are expected to occur.


DIVING PROJECT PLAN




11.3 HAZID Workshop The HAZID workshop is scheduled when a work procedure has been issued at Revision B. The purpose of the HAZID workshop is for the Project Management Team (including COMPANY representatives) to perform a detailed review of the procedure to identify hazards arising from the scope of work, quantify risk against a Risk Matrix and agree on control measures. External expertise is solicited where deemed necessary. Diving personnel are required to participate in HAZIDs on procedures where diving activities will occur to provide hands on expertise.

The outcome from the workshop will be entered into the project specific Risk Register. The Project Manager reviews the hazard, allocates a champion and sets a deadline for completion of the corrective action. The allocated Champion is responsible for close out of each item. Close out shall be recorded on a HAZID Action Close Out sheet. The Closed out HAZID form will be attached to final work procedure for COMPANY approval and the HAZID register closed out by CONTRACTOR.

All HAZID items must be closed out prior to the work related to the procedure commencing. Some HAZID items may not be closed out at the primary prevention stage, site actions will be required to ensure risks are mitigated.

11.4 Job Hazard Analysis Despite efforts to reduce risk during the engineering phase of a project, there will be a degree of residual risk associated with each task performed. It is necessary to manage this risk at the work site.

The primary tool for risk management at the work site is the JHA which will be supplemented by the Step Back 5 x 5 programme, these are described in depth in the HSE Management Plan (TS008593-PLN-7200-0001). JHAs developed for each operation will be kept on file and an electronic register will be available for reference throughout the project. Where unforeseen hazards are identified during diving operations, the JHA will be reviewed to reflect the hazard and measures taken to mitigate those risks.

Where residual risk remains PPE may be used as a last resort to reduce risk to ALARP.

11.5 Management of Change

11.5.1 Offshore Phase Where it is necessary to deviate from the procedure the Offshore Management of Change Procedure (GWP-PRJ-218) will be implemented. Each deviation associated with that task will be assessed to determine the effect of the change; this process is described in, Offshore Management of Change Procedure.

11.5.2 Onshore Phase The CONTRACTOR Onshore Management of Change Procedure (GWP-PRJ-211) is used, where a change is required during the engineering phase. Internal changes are initiated by the Responsible Engineer and recorded. The proposed change will be reviewed by discipline Lead Engineers and specialists for impact on areas within their responsibility.


DIVING PROJECT PLAN




12.0 INCIDENT REPORTING AND INVESTIGATION Any injury, near miss, or hazard shall be verbally reported to the OCM, Vessel Master and COMPANY RE upon occurrence, in accordance with CONTRACTOR Incident Investigation and Reporting Procedure (GWP-HSE-207). The responsibility for initial reporting of an incident rests with the individual and immediate supervisor.

Following an incident the COMPANY RE shall be informed immediately and a copy of the CONTRACTOR Initial Incident Report presented to the COMPANY RE as soon as completed. ‘Immediate’ means after due consideration to treating the injured person and securing the site, but should normally be within one hour of the incident.

Corrective actions shall be tracked and closed out in a time frame acceptable to COMPANY and CONTRACTOR management.

In accordance with the requirements of the Incident Investigation and Reporting Procedure GWP-HSE-207, the immediate Supervisor will ensure the report form is properly completed and immediately copied to:

Project Manager (onshore), who will liaise with the COMPANY Project Manager and in turn with the appropriate Regulatory Authority as necessary

Project HSE Manager

QHSE Manager (onshore)

COMPANY Representative (site or located in COMPANY office)

File project office

Incident reports will be monitored by the Project HSE Co-ordinator and evaluated for adverse trends; corrective steps will be taken to prevent reoccurrences as necessary.

12.1 Legislative Requirements For any incident occurring onboard the DSV, CONTRACTOR as the nominated operator, shall comply with the regulatory reporting as per clause 41 of Schedule 7 of the PSLA.

The requirement for monthly reporting is described in the regulations made under the Petroleum (Submerged Lands) Act 1967. The relevant regulation is in:

Petroleum (Submerged Lands) (Management of Safety on Offshore Facilities) Regulations 1996, Part 5, Regulation 46, Sub-Regulation 4.

(4) As soon as practicable, but not later than 15 days after the end of each month, the operator of a facility must submit, to NOPSA, a written report, for that month. This shall be completed by CONTRACTOR QHSE Manager.

12.2 Investigation The direct Supervisor of the location where an incident occurred will be responsible for carrying out the investigation, with the assistance of the Offshore HSE Coordinator. A member of the Vessel Safety Committee may be asked to participate. All investigations will be performed as per CONTRACTOR Incident Investigation and Reporting Procedure (GWP-HSE-207), which provides guidance to the personnel required to investigate incidents of varying severity.


DIVING PROJECT PLAN




13.0 MONITORING

13.1 Records Diving Operations records will be kept in accordance with Section 32 Petroleum (Submerged Lands) (Diving Safety) Regulations 2002.

13.2 Continual Improvement A fundamental element of any Risk Management process is to ensure that experience is collated and disseminated to improve methods of work and avoid repetition of mistakes.

The following processes are used to provide this feedback:

ORCA II Refer to HSE Management Plan, (JA014704-101-PLN-7200-0001)

Hazard Observations Refer to HSE Management Plan, (JA014704-101-PLN-7200-0001)

Systems Improvements where employees are encouraged to formally submit suggestions for improving a management system or process

Lessons learnt from incidents

Project Close Out/Lessons Learned (Refer to GWP-PRJ-215)
