Oilfields must increase their production due to the current price of oil barrels. The sale of these oilfields by big companies enabled new companies to enter the exploration and production segment of brownfields to increase oil and gas production through subsea intervention projects. However, these projects require specific product development that involves technical requirements that the engineering department must analyze. This research aims to apply the SWARA-MOORA-3NAG multicriteria decision analysis (MCDA) method in analyzing the technical proposals of subsea intervention equipment for ordering suppliers according to the engineering requirements defined at the initial stage of the projects of an oil and gas company. The research methodology was divided into five stages: (1) identification of the problem through observation of the current process and interviews with engineers; (2) data collection through bibliographic research in the Scopus database; (3) problem modeling; (4) proposition of the solution with the application of the SWARA-MOORA-3NAG method; and (5) analysis of the results found. The application of the SWARA-MOORA-3NAG method brought a new ordering of suppliers to the analyzed case, enabling comparison between the method previously used by the engineering department and the method proposed by this research, emphasizing that the MCDA methods can be inserted into the analysis processes of technical proposals in the engineering department of the company analyzed.

A variação do preço do barril de petróleo no mercado global aumenta a competitividade das empresas da indústria de óleo e gás nas atividades de exploração e produção, sendo a melhoria no atendimento ao cliente fundamental para a sobrevivência das empresas prestadoras de serviços. Neste contexto, a aplicação da metodologia design thinking possui uma função essencial no desenvolvimento de soluções para intervenções submarinas nesta indústria, visto que o atendimento ao prazo de entrega e as necessidades do cliente são fundamentais para que não haja interrupção na produção de petróleo. O objetivo deste estudo é analisar como o design thinking, associado aos métodos de desenvolvimento de produto design for manufacturing (DFM) e design for assembly (DFA), pode ser inserido nos processos de engenharia de sistemas de uma empresa multinacional do segmento de óleo e gás para potencializar os resultados durante a execução dos projetos de desenvolvimento. O design thinking é inserido no método de pesquisa soft design science research para construção de uma solução que reduza os impactos nos desafios encontrados. Os resultados obtidos, tais como a interação entre os departamentos de engenharia, projetos, operações e compras, auxiliam no gerenciamento das atividades de desenvolvimento de produto, visando o atendimento às necessidades operacionais, de prazo e custo do usuário final.

This study ranks and discusses the 7 dimensions of the circular economy in the context of Industry 5.0 proposed by Payer et al. (2024): Energy Circularity, Circularity of Inputs, Investments in circularity, Establishment of new circular businesses, Circular and non-circular supply chain integration, Circularity of product components, and Compliance and governance for circularity. The Hierarchical ordering (ranking) between these dimensions is done using the Analytic Hierarchy Process (AHP) method based on the opinion of 7 experts consulted (one expert for each dimension). These experts also discussed the main issues in evidence within these 7 dimensions. Organizations that aim to move towards the circular economy in the context of Industry 5.0 often need to prioritize efforts and start by treating some aspects, so this ranking can be a proposal of which dimensions can be prioritized in this scenario
