“The company will spend an estimated U$2.2 billion in-country, on PNG LNG Project related activities and on an extensive gas and oil exploration, appraisal and development programme,” Oil Search said in a statement Tuesday.
The exploration and appraisal work is aimed at finding more gas for a future expansion of the 6.6 million tonne per annum PNG LNG plant as well as proving up gas reserves for the Gulf Area LNG opportunity.
Oil Search sees Gulf Area LNG as a valuable long term growth opportunity as the company could potentially become a participant in two LNG projects or even an LNG project operator.
McDermott Australia (McDermott) has awarded Heerema Marine Contractors Australia Pty Ltd (HMC) a contract to transport and install infield flowlines, subsea structures and moorings for the INPEX Ichthys LNG Project.
McDermott Australia has been appointed the main contractor for the subsea umbilical, riser, flowline (SURF) project by INPEX. McDermott will work with HMC on the complex offshore installation campaign. HMC will carry out the transportation and installation of a portion of the offshore scope, utilizing the heavy lift, J-Lay and Reel-Lay capability of Heerema’s new-build vessel Aegir.
Scope of work
HMC’s scope of work includes the transportation and installation of flowlines, production flowlines, integrated pipeline structures, large subsea structures, a subsea riser support structure, and moorings for future FPSO and CPF facilities.
All pipeline production welding, both onshore and offshore, will be carried out by HMC’s subsidiary Pipeline Technique Ltd.
Aegir’s cutting-edge technology
The project logistics are of an unprecedented scale in HMC’s subsea track record. It involves lowering over 100,000 tonnes of project materials to the seabed in water depths up to 275 meters.
HMC’s Executive Vice President Commercial & Technology Steve Preston says: “This is a really exciting opportunity for us, not only because of the enormous scope of the project, but also because we will be able to demonstrate the groundbreaking capabilities of our new vessel Aegir. We will be able to use its heavy lift, J-Lay and Reel-Lay capabilities all in one project.”
Ichthys LNG Project
The Ichthys LNG Project is a joint venture between INPEX (76%, the Operator) and Total (24%). Gas from the Ichthys Field, in the Browse Basin approximately 200 kilometers offshore Western Australia, will undergo preliminary processing offshore to remove water and extract condensate. The gas will then be exported to onshore processing facilities in Darwin via an 889-kilometer subsea pipeline. The Ichthys LNG Project is expected to produce 8.4 million tonnes of LNG and 1.6 million tonnes of LPG per annum, along with approximately 100,000 barrels of condensate per day at peak.
