- The FIRST SCHEDULE of the Licence is varied by deleting the current text under the heading ROUTE OF DN150 (6”) FLEXIBLE PIPELINE and substituting the following:
The route of the pipeline is described in the table below, and displayed in the map below, commencing at the downstream flange on the Cobia platform riser Last Valve Off (LVO) isolation valve and terminating at the upstream flange to the Halibut platform riser First Valve On (FVO) isolation valve within a 20 m corridor (± 10 m centred on the pipeline). Coordinates are based on Geodetic Datum of Australia (GDA94).

Coordinate set above is based on GDA94 / MGA Zone 55 and is the centreline for the pipeline corridor.
* The flexible pipeline was laid from the Halibut to Cobia platforms, hence the curves are in the reverse order from the KPs that start at the Cobia platform and which are in the direction of the process flow.
** KP = Kilometre Point (approximate. Start point defined as the riser tie-in location at Cobia.)
2. The FIRST SCHEDULE of the Licence is varied by deleting the Cobia-Halibut Petroleum Pipeline route schematic and replacing it with the map at Attachment 1.
3. The SECOND SCHEDULE of the Licence is varied by changing the CBA riser length in item 3 of the table ‘Basis of Design – Cobia and Halibut Platform risers’ from 200 m (approximate) to 100 m (approximate).
