The scope of work includes the tie-in of Woodside's second trunkline into the existing infield facilities near the North Rankin A platform, via hyperbarically welded and flanged spoolpieces and a 350Te valve manifold. The second trunkline work also includes the dewatering and conditioning of the trunkline and stabilization of the trunkline by installation of approximately 900 concrete gravity anchors. Following start up of the second trunkline, extensive pipeline system modifications on the existing first trunkline at North Rankin A platform will be carried out.
Engineering has just started and the offshore works will be carried out in three phases during the period August 2003 to April 2004. Technip-Coflexip's vessel CSO Venturer will be used for the offshore works.
