The Federal Government has awarded Petrofac Facilities Management Limited Phase 1 of the Northern Endeavour decommissioning project.
It is moored in 380m of water in the Timor Sea, approximately 550km from Darwin, Australia and 250km from Kupang, West Timor.
The facility includes a network of subsea wells tied back to the vessel unit through a system of subsea manifolds, flowlines, umbilicals, and dynamic risers.
Produced oil was stored onboard the vessel and unloaded via offtake tankers using a tandem mooring system.
With no further production being undertaken, the now redundant facility is depressurised and all wells are shut in with subsurface safety valves closed.
According to the Department of Industry, Energy, Science and Resources website, decommissioning the facility and remediating associated oil fields would be the most cost-effective way to protect the environment and remove future potential risks.
The department said $325m decommissioning contract adhere to industry and Australian standard, working with working with industry and regulators to ensure the work was done as safely, efficiently and cost-effectively as possible.
