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

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

RasGas will be informed of all hot work requirements after the site verification study.
5.6 Habitats
Consultation is required with RasGas operations before establishing temporary habitatrequirements prior to construction work commencing. HHI is to supply and install the
necessary material for the habitats.
5.7 Scaffolding
HHI will ensure Scaffolding erected for installation activities does not inhibit F&G
detection or deluge system.
Plans for Scaffolding will be submitted by HHI to RasGasOperations30 days in advance
of any planned erection.

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.
