The Barossa Gas Development, located approximately 300 kilometres offshore from Darwin in the Northern Territory, comprises a Floating Production Storage and Offloading (FPSO) facility, a subsea production system, supporting in-field subsea infrastructure and a Gas Export Pipeline (GEP).

Once complete, the Barossa Gas Development will transport natural gas from the offshore Barossa field via the Gas Export Pipeline to the existing Darwin liquefied natural gas (DLNG) plant. The development is expected to deliver natural gas commencing in 2025.

Barossa gas is a critical energy source and will ensure affordable and reliable energy for Santos’ customers for decades to come.

The Barossa project will create and sustain hundreds of jobs in the Northern Territory and will inject significant money into the local economy, helping to ensure the continued regional development of northern Australia.

Gas Export Pipeline

The Gas Export Pipeline (GEP) is a 262 kilometre long, 26-inch diameter pipeline that is required to connect the Barossa field to the Darwin LNG plant.  The pipeline route was carefully selected to minimise environmental impacts and risks. The pipeline installation is a low-impact activity. There will be no dredging or trenching.

Santos is undertaking further assessments to ensure identification of any underwater cultural heritage places along the route. We are engaging independent experts to undertake this assessment. Santos wants to hear from anyone with spiritual or cultural connections to any underwater cultural heritage places along the pipeline route.
