Technip was awarded a pipeline installation contract by Woodside Energy Limited for the Greater Western Flank Phase 1 Project located 130 kilometers North West of Karratha in Western Australia.

Woodside Chief Executive Officer and Managing Director, Peter Coleman said the project would maintain offshore supply to the Karratha Gas Plant and support the North West Shelf Project’s ongoing marketing efforts for domestic gas and LNG.

“This Project will continue to maximise the value of existing infrastructure and demonstrates ongoing investment in Australia’s largest resource project” Mr Coleman said.

This pipeline will link the Goodwyn GH and Tidepole fields via a subsea tie-back to the existing Goodwyn A (GWA) platform and represents the next major development for the Woodside-operated North West Shelf Project.

The contract scope includes load out, transportation and installation of 16 kilometers of 16” gas flow line from the Tidepole manifold to the GWA platform.

Technip’s operating center in Perth, Australia will execute the contract, with the support from the Singapore office. Offshore installation will be carried out by the Global 1200 or the Global 1201, two flagship vessels that joined Technip’s fleet through the recent acquisition of Global Industries.

About the Karratha Gas Plant
Located 1260 km north of Perth, Western Australia and covering approximately 200 hectares, the Karratha Gas Plant includes five LNG processing trains, two domestic gas trains, six condensate stabilization units, three LPG fractionation units as well as storage and loading facilities for LNG, LPG and condensate.

One of the most advanced integrated systems in the world, the Karratha Gas Plant has the capacity to produce:

  • Domestic gas – 12,000 tonnes/day (firm customer commitments equate to approximately 600TJ per day)
  • LNG –  52,000 tonnes/day
  • LPG –  4,200 tonnes/day
  • Condensate –  165,000 barrels/day

In 2008 annual LNG production capacity at the Karratha Gas Plant increased to 16.3 million tonnes with the start-up of a fifth, 4.4 million tonne-a-year LNG processing train.

About the Greater Western Flank Development
The North West Shelf Venture is progressing pre-development studies, including appraisal drilling of Tidepole-2, to define
the development plan sequence for commercialisation of the undeveloped petroleum resources in the Greater Western
Flank (GWF) area.

This area, to the south-west of the Goodwyn A platform, contains 14 fields which are estimated to hold approximately three trillion cubic feet of recoverable gas and approximately 100 million barrels of condensate. Concept selection and front end engineering design for the GWF development is expected in 2010.
