Jacobs Engineering Group has secured multi-year engineering services agreement to support the sustaining capital program for the Australia Pacific LNG facility upon completion for ConocoPhillips.

Under the agreement, Jacobs will be responsible for engineering studies, front-end engineering design (FEED) services, and detail design including procurement, commissioning and construction support for sustaining capital and mid-cap projects at the facility, for over four years.

The agreement also includes the option to extend for a further four years.

Located on Curtis Island in Queensland, Australia, the facility features two LNG trains, each capable of producing 4.5Mtpa of LNG.

First LNG is planned from Train 1 in mid-2015 while Train 2 startup is scheduled approximately 6-9 months thereafter, the company said.

The ConocoPhillips-operated Curtis Island plant can accommodate future growth, with the potential to integrate up to four LNG trains.

Jacobs Group vice president Phil Lory said: "We are very pleased to continue our strong relationship with ConocoPhillips and deliver this landmark program in Australia.

"This sustaining capital agreement supports our client focused, long term project program strategy in Australia, and we look forward to leveraging our global capability to support ConocoPhillips and the Australia Pacific LNG team in their goal to maintain a safe, efficient LNG facility."
