### Saipem’s Scarborough Trunkline Offshore Australia Enters Pre-commissioning Phase
In a significant milestone for the oil and gas industry, Saipem has confirmed that its Castorone construction vessel has completed all trunkline installation activities for the Woodside-operated Scarborough gas field development offshore Western Australia. This massive project, valued at $12.5 billion, marks a crucial step towards its operational readiness.
The Castorone vessel has spent over a year laying 433 kilometers of pipeline, with the exquisite task of placing more than 36,000 lengths of pipe in water depths of up to 1,400 meters. This extensive effort is part of the broader initiative to transport gas from the offshore Scarborough field to the onshore Pluto LNG processing facility in Karratha.
Woodside Energy, the operator behind this project, awarded Saipem the contract in 2022, which included the laying, transportation, and coating of the trunkline. This extensive network will play a vital role in connecting the offshore energy fields to the onshore processing facilities, ensuring a seamless flow of natural gas.
With all trunkline installation activities now complete, Saipem will proceed with pre-commissioning activities ahead of the hookup of subsea infrastructure to the onshore terminal. This phase is critical in ensuring that all systems are properly tested and ready for operation, a key step before the trunkline goes into full production mode.
