Woodside Energy Ltd (Woodside) is operator of the North Rankin Complex (NRC), which is located offshore in Production Licence WA-1-L approximately 135 km North of Dampier and 23 km North East of the Goodwyn Alpha (GWA) facility, Western Australia. The NRC is a single integrated facility which is comprised of two platforms, the North Rankin A (NRA) and the North Rankin B (NRB) platform. The two platforms are now fully integrated and operating as one complex, with low pressure operations from the NRC first commencing in December 2013. The facility stands in approximately 125 m of water.
Gas and condensate is transported to the Karratha Gas Plant via a trunkline system for processing. Approximately 105 km of the trunkline length is located in Commonwealth waters and included in the scope of the NRC EP; the remaining lengths are located in State waters and are the subject of a separate EP.
Normal operations at NRC fall under the following modes of operation:
Production and maintenance;
Production and well maintenance;
Subsea IMR activities;
Production and major projects; and
Additional operational activities in relation to the EP include:
Operational and emergency flaring of excess gas through independent NRA and NRB flare systems;
Processing and discharge of drainage, cooling and brine water; and
Processing and discharge of Produced Formation Water (PFW) within discharge limits.
The proposed Persephone Development (a separate activity) comprises a two well subsea tieback to the NRC and remains subject to a final investment decision by the North West Shelf Project. When implemented, this development will include a flowline running from the subsea wells located at the Persephone field approximately 6.9 km to the North East of NRC. NRC modifications associated with the Persephone Development, required prior to first gas, are included within the NRC EP
