ROUTE OF THE PIPELINE
The pipeline route for the system of pipes commences at the upstream connector hub face of the inline tee (ILT) of the Julimar Phase 2 (JDP2) rigid pipeline (Petroleum Pipeline Licence WA-29-PL) to the production jumper end fitting hub faces, connecting to downstream Diverless connectors at the JUB1A and JUB1B Christmas tree ends, via two infield production flowlines tied back to the JULB manifold, within a 40 m corridor (± 20 m centred on the pipelines) as described in the tables hereunder and displayed in the attached map (Attachment 1).
