CODA Partner sustain:able will be presenting at the SPE Symposium: Asia Pacific Decommissioning and Well P&A, taking place in Perth Australia, 11–12 November, 2025
Their paper, titled “Optimising Decommissioning Strategies: A Case Study on Emissions and Cost Reduction in Offshore Operations” presents a comparative assessment of full infrastructure removal, partial removal, and leave-in-situ scenarios, focusing on emissions and costs.
The study demonstrates how emissions forecasting tools can be applied to offshore decommissioning to identify high-impact activities, optimise vessel and power use, and highlight opportunities for cost and emissions savings. Using a North Sea case study, the analysis compares scenarios ranging from full infrastructure removal to partial removal and leave-in-situ options, showing that lower-emission strategies can often align with lower overall costs.
By integrating emissions into decommissioning planning, operators can make more informed decisions, reduce carbon liabilities, and strengthen ESG performance. These insights are highly relevant to Australia as the industry prepares for a wave of decommissioning projects, with regulators and stakeholders increasingly expecting emissions-informed strategies alongside cost efficiency and safe execution.
