A global review of decommissioning planning and execution of learnings

The objective of this project is to understand key learnings arising from decommissioning planning and execution in comparable jurisdictions. These learnings should inform improved design of planning and execution to support CODA’s objectives.

Long term planning for design and execution is considered the most contributor to improving efficiency in the decommissioning process. Reducing the overall cost and maximising the potential benefits of decommissioning activities is, in part, facilitated by long term approvals which allow for flexible activity windows.

Long term approvals provide for innovative and opportunistic approaches to these activities, such as multi-asset campaigns or the application of new technologies. Regulatory approvals are currently estimated to account for nearly $600 million of Australia's total offshore decommissioning liability, with potential reductions driven by collaboration and efficiency.

CODA seeks to understand:

  • Approaches, initiatives or projects that have contributed to improved outcomes in other jurisdictions with decommissioning planning and execution.
  • Areas of key risk that been identified in comparable jurisdictions relating to decommissioning planning and execution, for example, areas of heighted safety risk.
  • Jurisdictional experiences (United Kingdom, United States and Norway) with full removal or in-situ decommissioning of infrastructure. CODA is particularly interested in the instruments and evidence-base that supports these decision making frameworks
  • International experiences with the process of relinquishment of a petroleum title, including associated requirements and precedents or case studies relating to long term monitoring of in-situ assets.
