Oil and gas exploration company ConocoPhillips has awarded an engineering, procurement and construction and installation (EPCI) contract for the Barossa offshore project to Allseas Marine Contractors Australia.
The scope of the contract includes procurement, transportation and installation of the 260km pipeline, as well as project management, engineering and other associated services.
ConocoPhillips Australia Barossa is the operator of the Barossa joint venture (JV) and owns 37.5% interest in it, while SK E&S Australia (37.5%) and Santos Offshore (25%) are other companies in the JV.
The development concept of the offshore project includes floating production storage and offloading (FPSO) facility, subsea production system (SPS) and gas export pipeline, which will be located in Commonwealth waters north of Darwin.
Natural gas will be transferred by the pipeline from the development area located 300km north of Darwin to a tie-in location on the existing Bayu-Darwin Pipeline 100kms north-west. The Barossa Offshore Project will provide a new source of gas to the existing Darwin LNG facility and is currently in the front-end engineering design (FEED) phase.
This contract follows earlier awards for engineering, procurement and construction (EPC) of the subsea production system to Technip Oceania (TFMC) in May 2019.
ConocoPhillips Australia West president Chris Wilson said: “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.
“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.”
The company said that Barossa will meet future global demand for natural gas and contribute significant income and employment to the Northern Territory as well as Australia through operations of the Darwin LNG facility.
