1.0 SUMMARY

1.1 Justification

The existing potable water system on the RGA LQ will be tied into and combined with the new

potable water system on the ALQ. This will provide greater capacity and flexibility.

1.2 Corresponding eMOC Number

This will be supplied by RG eMOC initiator in a later revision.

1.3 Outline Scope of Work

1. Install all new required pipe supports (pipe supports are detailed in the pipe support

workpack).

2. Under the guidance of RG Operations& PMT conduct all required shutdowns (QT-Y-9402Potable water Press. Set), isolations and LOTOs (5 valves total, see section 1.9.1).

3. Depressurise as required.

4. Remove blind at TP-PI-07A

5. Install tie in tee piece (including new isolation valve HV393 NC in closed position).

6. Carry out any required testing

7. Under the guidance of RG Operations & PMT remove all isolations and LOTOs.

8. RG Operations to bring QT-Y-9402 Potable Water Press Set back into service.

9. Install piping (new line QT-WPT-840-4”-DBS1) between tie in location TP-PI-07B and ALQ

5.0 SAFETY

Refer to JSA attachment 7.

5.1 General

All construction activities shall comply with the RasGas Safety Management System.

5.2 Permit to Work System

The RasGas Permit To Work system has been designed to assist CONTRACTOR and

operating personnel working on RasGas offshore installations to carry out work in

accordance with safe working practices.

The PTW system includes regulations, procedures, documentation and guidance notes

laying down the conditions of work and precautions which must be taken by HHI during

the execution of any work to ensure safety of both personnel and plant. The permit to

work system has been designed as both a working and reference document.

The permits issued for work in this workpack will be discussed at the permit meeting prior

to the commencement of the work.

All permits must be applied for by HHI PTW trained personnel a minimum of 24 hours in

advance of commencing the work.

5.3 Safety Checklist

The following activities will be carried out :

a. Discuss work scope permits with the production / discipline supervisors

b Tool box talk with foreman / charge-hand

All required work to complete this workpack will be executed under the RG PTW system. All PTW will

be completed and submitted to RG Operations the day before the planned work.

HHI will only perform LOTO and Isolations under the guidance of RG Operations & RG PMT.

All bolts will be hot bolted before proceeding with tie-in work.

Testing will be as per the line list.

Prefabrication of pipe spools will be maximized.

This work will be completed in stages as per the level 3 schedule. This workpack can only be

completed after the ALQ installation.

Any pipe work that is pre-installed before the ALQ installation will have a cap end installed to protect

the pipe.

Scaffolding will be set up so all workers have a safe working platform.

This work will be conducted by the following team: 1 supervisor, 5 pipefitters & 1 safety.

11.0 AS BUILDING

HHI will follow the BARZAN Project as-building procedure.

The contractor shall be responsible for preparing redline as built mark-ups for any agreed

deviation to the AFC design during installation, pre-commissioning and commissioning.

During installation, all design changes must be marked-up / as-built on the relevant

drawings and collated onto the designated RasGas workpack set of documents. Upon

completion of mechanical completion / commissioning / system hand-over, all drawings

must be stamped “As-Built”, signed and dated (including those drawings that have no

changes). Contractor to prepare field sketch for any obstruction / clashing occur as per project design

document and shall obtain RasGas PMT Operations approval prior to start with the work.
