INPEX have announced the record breaking subsea pipeline, part of its offshore Ichthys LNG project is now complete, offshore Australia’s Norther Territory.

The Japanese oil company announced the news today (5th Nov), as the Saipem’s SEMAC and CASTORONE pipe lay vessels completed the work.

The subsea pipeline will connect the offshore Ichthys gas condensate field, to the LNG processing facility at Bladin Point, near Darwin Australia.

The 890 km (553 mi) long, 42 inch diameter pipeline now holds the record for the longest longest subsea pipeline in the southern hemisphere, and the third longest in the world.


The work took 17 months to complete, having started on in June 2014, with two pipelaying vessels working around the clock.

Ichthys Project Managing Director, Louis Bon, said: “Completion of the offshore pipelay marks a significant milestone for the project, 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.”
