A restorative approach to decommissioning
As offshore oil and gas assets approach the end of their working life, there is an opportunity to plan ecological recovery alongside removal. A decommissioning program can consider what habitat was disturbed, what new habitat can be built and how seabed communities will be measured after the work.
Nature-based methods may include artificial reef structures, reseeding of sponge gardens and restoration of native shellfish reefs or seagrasses where the conditions suit them. These habitats can support marine life, water quality and carbon cycling.
The approach also asks project teams to limit damage during removal. Careful management of sediment and materials can help make restoration efforts more effective and support a healthier seabed over time.
A strong strategy brings industry, regulators and community stakeholders together early, so decommissioning can leave an ecological benefit and a useful evidence base for future offshore projects.
