As titleholder on behalf of its joint venture participants, INPEX has been expanding and further developing the Ichthys Field with URF and SPS installation activities (2020-2025) addressed in the in-force Ichthys URF and SPS installation environment plan (EP) (E075-AD-PLN-70000).
Due to unforeseen project and weather delays, the scope covered by E075-AH-PLN-70000 remains unfinished. Therefore, this URF EP 5-year revision includes the following activities planned in WA-50-L:

• Ongoing installation, tie-in, pre-commissioning, mechanical completion and commissioning of well jumpers and associated control systems at existing drill centres in WA-50-L; a continuation of the activities described in E075-AD-PLN-70000 that have not yet been completed due to delays.

• Geophysical and geotechnical surveying of the seabed within WA-50-L for future URF and SPS installation activities.

These activities will be conducted using various construction, installation, support, survey vessels and remotely operated vehicles (ROV) and autonomous underwater vehicles (AUV) with personnel transfers conducted by helicopter.

The Ichthys Field, within production licence WA-50-L, is located in the Browse Basin in Commonwealth waters within Western Australia. It is approximately 230 km north west of the Kimberley coastline, at its closest point. Water depths in the permit area range between 235 m and 275 m at lowest astronomical tide. The closest major town is Derby, located approximately 390 km south of the southern boundary of the licence area. The duration of this activity is for 24 months.
