A Rio Innovation Week, que aconteceu no Pier Mauá, de 12 até 15 de agosto de 2025 e é considerado o maior evento global de tecnologia e inovação da América Latina.
A COPPE / UFRJ leva suas pesquisas nas áreas de energia, mobilidade, saúde, indústria e inovação social, ao longo de todos os dias do evento, além disso, professores e pesquisadores participarão de painéis temáticos, como foi o caso de Ricardo Nunes, membro do DESCOM .SUB COPPE / UFRJ e aluno de doutorado do Programa de Engenharia de Produção da Coppe.
Ricardo apresentou um Pitch sobre Descomissionamento Sustentável de ativos da indústria de petróleo.

Na segunda-feira, 28 de julho, a pesquisadora Beatriz Bandeira da equipe de Saúde e Segurança do DESCOM .SUB, apresentou o artigo “Work and Safety in the Decommissioning of Flexible Lines” durante o AHFE 2025.

O congresso, realizado entre os dias 26 e 30 de julho, em Orlando na Flórida, está na sua 16a edição, e é um dos principais congressos internacionais nas áreas de #fatores humanos, ergonomia e sistemas complexos, promovendo o intercâmbio técnico e científico entre pesquisadores de todo o mundo.

O objetivo da conferência é proporcionar um fórum internacional para a disseminação e o intercâmbio de informações científicas sobre as áreas teóricas, genéricas e aplicadas de fatores humanos e ergonomia e tem em sua programação, apresentação principal, sessões paralelas, sessões de demonstração e pôsteres, tutoriais, exposições e reuniões de grupos de interesse especial.

A participação no evento reforça a importância de considerar os aspectos humanos no processo de transição energética e nas operações offshore, contribuindo para práticas mais seguras e sustentáveis.

Dimensionality reduction for multi-criteria problems: An application to the decommissioning of oil and gas installations

29/08/2024 DescomSub No Comments

This paper is motivated by decommissioning studies in the field of oil and gas, which comprise a very large number of installations and are of interest to a large number of stakeholders. Generally, the problem gives rise to complicated multi-criteria decision aid tools that rely upon the costly evaluation of multiple criteria for every piece of equipment. We propose the use of machine learning techniques to reduce the number of criteria by feature selection, thereby reducing the number of required evaluations and producing a simplified decision aid tool with no sacrifice in performance. In addition, we also propose the use of machine learning to explore the patterns of the multi-criteria decision aid tool in a training set. Hence, we predict the outcome of the analysis for the remaining pieces of equipment, effectively replacing the multi-criteria analysis by the computational intelligence acquired from running it in the training set. Computational experiments illustrate the effectiveness of the proposed approach.

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

29/08/2024 DescomSub No Comments

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.
