Repurposing Offshore Oil Platforms for Wind Energy and Flexible Electrical Load Management: Multi-Criteria Decision Analysis of 62 Brazilian Decommissioning Programs

The Takeaway
Decommissioning offshore oil platforms is a multi-billion dollar headache for the environment. This research proposes turning those rigs into 'energy islands' that host wind turbines and use high-speed computing (like crypto mining) to handle the extra electricity. Because wind is inconsistent, 'mining' acts like a flexible battery—it uses up the power when it's windy and shuts down when the grid needs that energy elsewhere. It turns a massive liability into a profit-making, green-energy machine. It’s the ultimate 'circular economy' play: using the infrastructure of the fossil fuel age to power the digital and renewable future.
From the abstract
Offshore platform decommissioning represents a growing financial and environmental burden for the global petroleum industry. In Brazil, 120-150 platforms face decommissioning over the next two decades at an estimated total cost of USD 15-25 billion, with conventional removal generating 15,200-24,900 tCO2 of emissions per platform. Despite regulatory provisions for alternatives within the PDI framework (ANP Resolution 817/2020), no systematic multi-criteria evaluation of decommissioning strategi
