The Ichthys Field is located within the area covered by production licence WA-50-L, in the northern Browse Basin, approximately 210 km north-west of the coast of mainland Western Australia and 820 km south-west of Darwin. 
Activities to be managed under the Gas Export Pipeline – Precommissioning Environment Plan are:
the leak test of the 42-inch tie-in spool connections which involves pumping liquid into the infrastructure until a pre-set pressure is achieved. This ensures that infrastructure connections have met design specifications; and
precommissioning the gas export pipeline which involves removing preservation fluid and ensuring the pipeline is rendered inert before receiving hydrocarbons.
The leak-test and precommissioning activities will result in discharges from the gas export riser base within the URF Site which is located within Commonwealth waters.
The activities are scheduled to be performed between mid-2015 and mid-2016.
