A Dutch offshore contractor focusing on subsea construction, pipeline laying, and heavy lift, Allseas, has completed the construction of the Barossa gas export, which spans 262 kilometers. 

The Audacia, a pipelay vessel owned by Allseas, successfully completed the Barossa gas export pipeline in the southern Timor Sea. 

The project involved installing two Pipeline End Termination (PLET) structures, marking the culmination of years of engineering, fabrication, and offshore operations. 

Allseas collaborated with its Australian fleet to support the pipelay activities.

“This project presented significant challenges,” an Allseas spokesperson said. “Our crews operated in one of the world’s most remote environments, with a complex supply chain and demanding weather conditions, including high humidity and extreme tidal fluctuations.”

The Barossa pipeline represents Allseas’ first project in the Northern Territory, building on its two-decade history of installing pipelines in Australian waters. With that, the company anticipates future opportunities in the region.

Following Audacia’s work, the Fortitude will now take over to survey and test the newly installed pipeline.
