Decisions in decommissioning projects: Bringing health and safety closer to future work.

29/08/2024 DescomSub No Comments

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.

Energia e direito regulatório sustentável: Um estudo de caso sobre o descomissionamento na indústria do petróleo no Brasil

O desenvolvimento sustentável como pauta da agenda mundial é uma realidade que deve ser buscada por cada setor, por cada empresa, por cada agente econômico. Na indústria do petróleo, o novo segmento que tem se desenvolvido de modo mais consistente nos últimos anos, chamado de descomissionamento já nasce apoiado em critérios de sustentabilidade bastante objetivos conforme se apresenta no presente trabalho. Este novo segmento do setor petrolífero nacional representa um significativo estudo de caso para se observar como é possível por meio de um alinhamento regulatório com a agenda sustentável do país buscar caminhos menos poluentes, menos agressivos ao meio ambiente. Por meio de revisão literária combinada com uma análise legislativa nacional e internacional busca-se apresentar cenários possíveis para o descomissionamento que contribuam com o desenvolvimento sustentável, em especial com o cumprimento dos objetivos de desenvolvimento sustentável promovidos pela ONU. Em relação aos resultados, as pesquisas seguem em andamento para que haja conclusões eficazes.

Invasive marine species and the decommissioning of offshore oil and gas installations: Challenges and sustainable management

Oil and natural gas (O&G) industries are significant players in the global economy. The lifecycle of O&G installations has reached an age at which many must be decommissioned. Biological invasion is the process by which a species is introduced into a new geographic region caused by the interference of human activities. Scientists and policymakers have identified invasive species as a significant threat to marine ecosystems affecting biodiversity. Today, O&G habitats and invasive species represent only 9% of biodiversity studies relative this field. We provide an overview of invasive species linked to decommissioning operations worldwide and emphasize the Brazilian context to support the sustainable management of decommissioning operations. O&G facilities have contributed to the spread of invasive species, such as the bryozoan Watersipora subatra in Santa Barbara Channel (California) and the sun coral species Tubastraea coccínea and T. tagusensis in the Gulf of Mexico and the Brazilian coast. The Brazilian case highlighted in this study shows several platforms to be decommissioning, and the presence of sun coral along the coast which poses biodiversity in risk. Measures must be taken to control the sun coral dissemination and some recommendations were made in this study to support futures studies.
