Allseas Scoops Large EPCI Pipeline Project from ConoccoPhillips
ConocoPhillips Australia, as operator of the Barossa joint venture, has awarded an Engineering, Procurement, Construction and Installation (EPCI) contract for the Barossa Gas Export Pipeline.
The contract awarded to Allseas Marine Contractors Australia Pty Ltd. includes procurement, transportation and installation of the 260-kilometre pipeline, project management, engineering and associated services.
The Barossa offshore gas and light condensate project is currently in the front-end engineering design (FEED) phase. Subject to commercial arrangements being agreed, Barossa will provide a new source of gas to the existing Darwin LNG facility when the current offshore gas supply from Bayu-Undan is exhausted.

Barossa’s offshore development concept includes a floating production storage and offloading (FPSO) facility, subsea production system and gas export pipeline, all located in Commonwealth waters north of Darwin, Northern Territory. The gas export pipeline will transport natural gas from the development area 300 kilometres north of Darwin to a tie-in location on the existing Bayu-Darwin Pipeline 100kms north-west of Darwin.
Award of the contract follows earlier awards for engineering, procurement and construction of the subsea production system in May 2019 and FEED engineering design contracts for the FPSO, subsea infrastructure and gas export pipeline in 2018.
ConocoPhillips Australia West President Chris Wilson said the latest contract award was another significant step in positioning Barossa as the leading and most advanced candidate to extend the life of the Darwin LNG facility for another two decades.
Hot Tip
“Award of this EPCI contract will enable specific project management and engineering deliverables to be progressed prior to a final investment decision in order to meet the project schedule,” Mr. Wilson said.
“We continue to focus on strong cost discipline with all our selected contractors, developing the certainty of cost, schedule and execution planning required to compete in our global portfolio and support a final investment decision.”
Barossa would meet future global demand for natural gas and contribute significant income, employment and other benefits to the Northern Territory and Australia through continued operation of the Darwin LNG facility.
The Industry Capability Network has been engaged by ConocoPhillips to assist with Australian vendor identification for the Barossa Offshore Project.
About the Barossa Offshore Project
The Barossa joint venturers are ConocoPhillips Australia Barossa Pty Ltd (operator, 37.5%), SK E&S Australia Pty Ltd (37.5%) and Santos Offshore Pty Ltd (25.0%).
The offshore development area encompasses petroleum retention lease NT/RL5 and potential future phased development in the smaller Caldita Field to the south in retention lease NT/RL6. Gas would be exported to Darwin LNG via a new export pipeline tied into the existing Bayu-Darwin Pipeline, subject to agreement with the infrastructure owners.
