APPLICATION FOR VARIATION OF

PIPELINE LICENCE VIC/PL21

The application seeks to effect the following amendments to the licence:

and

substituting under the heading the following:

“The route of the pipeline is described in the table below, and displayed in the map below

(Attachment A), commencing at the start of the steel pipeline near the Perch platform location before proceeding through two major deflections, and continuing in a straight line with minor deflections to a point which intersects the boundary of Commonwealth offshore waters at the 3 nautical mile limit.”

Coordinate set above is based on GDA 94/MGA Zone 55, survey of pipeline centreline.
