Decommissioning in Brazil faces challenges regarding the safe and efficient deactivation of industrial facilities, considering risks such as safety and health. Associating decommissioning with operational risk management methodologies can bring benefits in resource savings, worker safety, assessment of future scenarios, and transparency and accountability among stakeholders and society at large. This study aims to perform a comparative analysis of Worker Health and Safety data criteria using a multicriteria decision analysis methodology developed by COPPE/UFRJ, to define the best decommissioning alternatives for subsea installations, using data presented by the SAFETEC (Safety and Environmental Technology) Report and the CNAE (National Classification of Economic Activities) in the context of operational risk analysis. In the Brazilian scenario, worker safety involves challenging and industry-specific issues, and understanding the activities that are effectively carried out in decommissioning could prompt reflection on future work and contribute to mitigating the operational risks to which workers in this sector are exposed.
