There is more than $50 billion of necessary decommissioning work to be done on Australia’s offshore oil and gas infrastructure, over half of which needs to be started within the next ten years.
NERA is leading the implementation of the Centre of Decommissioning Australia (CODA) to deliver a transformational approach to late-life asset planning and decommissioning execution, which returns maximum value to the community, environment, industry, economy and Australia's future.
CODA will provide a collaborative platform for joint projects, knowledge transfer and innovation to maximise value for Australian businesses, the community, the environment and the economy from decommissioning activities.
Advisian Report: Offshore Oil and Gas
CODA welcomes submissions for proposals.
Due: 9 April 2021
NERA has officially launched the Centre of Decommissioning Australia (CODA).
Below are some examples of collaborative projects and initiatives that are supporting Australia to become a leader in life extension, repurposing and decommissioning.
National Decommissioning Research Initiative (NDRI)
The NDRI is the first long-term industry-wide oil and gas decommissioning research collaboration in Australia, delivering independent science to better understand the impacts of decommissioning oil and gas structures on the marine environment.
Coordinated by NERA, the NDRI provides an independent scientific evidence-base to improve understanding of how the decommissioning of offshore oil and gas structures influences the marine environment over time

Australian Decommissioning Liability Assessment
NERA has partnered with seven oil and gas operators to commission a project through Advisian to quantify Australia’s decommissioning liability and estimate potential savings that can be achieved through decommissioning activities.
Specifically, the project has:

Exmouth Integrated Artificial Reef project
The $1 million Exmouth Integrated Artificial Reef is a unique project that has enhanced marine habitat and recreational fishing opportunities, built as part of a collaborative project between Subcon, Curtin University, BHP, RecFishwest and the Exmouth community.
Installed in July 2018 on a previously barren seafloor, the Exmouth Integrated Artificial Reef is the largest purpose-built reef in the Southern Hemisphere and the first of its kind in Australia. The reef is now a thriving ecosystem and has seen over 100 different species of fish call it home.

Offshore platform in-situ collapse project
As an example of innovation, NERA co-funded Perth-based engineering consultants Linch-pin to investigate the feasibility of an alternative approach to decommissioning. This technique involves surgical cuts to a jacket which would encourage the structure to be intentionally collapsed in a guided way, to reduce the need for large vessels to support decommissioning.
Further information here.
Australian legislation requires oil and gas companies to remove any property installed within a permit area at the end of its life. A proponent also has the opportunity to demonstrate that alternative decommissioning approaches might deliver equal or better environmental, safety and well integrity outcomes when compared with complete removal.
Decommissioning options include:
NERA’s Decommissioning Strategy seeks to achieve the following objectives:
