In addition, significant progress has been made with other customers and it is expected that additional HOAs will be secured in the near term, said Oil Search.

This has given the project increased confidence that the full 6.3 mtpa capacity will be contracted by mid-year.

Oil Search owns a 34% stake in the project, which would generate 6.3 million metric tons of LNG a year, cost $10 billion and make its first delivery by 2014.

Other venture partners for the project comprise of Santos Ltd, Nippon Oil Corporation, Petromin Resources Limited and traditional landowners.
