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.
