DELFT, the Netherlands — Allseas’ pipelay vessel Audacia has installed its largest pipeline end termination (PLET) in S-mode for Santos’ Barossa gas-condensate development in the Timor Sea offshore northwest Australia.
Audacia, supported by the Fortitude, Alegria, Felicity and Fortress vessels, is laying Barossa’s 262-km, 26-in. diameter gas export pipeline. This will connect the field center to the future Darwin Pipeline Duplication, transporting gas to the Darwin LNG complex.
According to Allseas, the PLET structure was so heavy, it had to be installed separately to the connector head. In addition, its height and width meant it only fit through the tensioners and over the vessel’s stinger.
Project manager Dennis Telders said, “To make it work, we had to come up with a design that worked in S-mode, so over the stinger, as opposed to J-mode, over the side.”
Following tests last year, the crew was able to land the PLET safely onto its mudmat foundations, which Fortitude had set down on the seafloor earlier in the campaign.
