The 890 km, 1066.8 mm diameter gas export pipeline is the longest subsea pipeline in the southern hemisphere and the third longest subsea pipeline in the world.
The pipeline will deliver gas from the Ichthys Gas-condensate Field to the onshore facilities at Blaydin Point near Darwin for processing.
“Completion of the offshore pipelay marks a significant milestone for the project,” said Ichthys Project Managing Director Louis Bon.
“It means we are one step closer to physically connecting our onshore plant near Darwin to the Ichthys Field where our offshore facilities will be permanently moored for the 40-year life of the Project.”
The pipeline was installed by Italian company Saipem’s SEMAC1 barge and Castorone pipelay vessel from Darwin to the field.
INPEX will conduct other necessary work on the pipeline in preparation for operational start-up.
