Development Project (the Ichthys project) is a joint venture between INPEX group companies (INPEX), major partner, Total group companies, and the Australian subsidiaries of Tokyo Gas, Osaka Gas, Chubu Electric Power Company and Toho Gas. INPEX intends to develop the Ichthys Field in the Browse Basin off the north-west coast of Western Australia to produce liquefied natural gas (LNG), liquefied petroleum gas (LPG) and condensate for export to markets in Japan and elsewhere. The Ichthys gas field is located in the Browse Basin, approximately 210 km north-west of the coast of mainland Western Australia and 820 km west-south-west of Darwin, Northern Territory (NT), Australia (Figure 1-1). The Ichthys project will allow for the extraction and transmission of natural gas from the Ichthys gas field through the Gas Export Pipeline (GEP) to the onshore processing facilities at Blaydin Point in Darwin Harbour for processing into liquefied natural gas (LNG), liquefied petroleum gas (LPG) and condensate. Export of condensate for the international market will also occur directly from the offshore floating facilities via off-take tankers [Ref A1]. Figure 1-1 The Ichthys gas field and GEP route Saipem (Portugal) Comércio Maritimo (Australian Branch) (Saipem) has been awarded the engineering and installation contract by INPEX for the GEP associated with the Ichthys project. The GEP Environment Plan (EP) has been developed to cover Saipem’s scope of work in respect of the offshore GEP installation activities - from a pre-lay survey through to the completion of pipeline installation.
