Proposição de método delphi de edução para estimativa da confiabilidade de ativos off shore em ambiente de qualificação

Abstract

Reliability studies in the Brazilian pre-salt oil production environment have shown promise, as seen in surveys carried out between 2017 and 2023 on the platforms MaintWorld, Machinery and Equipment MRO, Science Direct, Google Academic and CAPES, mainly for the determination of frequency of occurrence of failure events, obsolescence of data and their behavior over time is one of the concerns in the context of current engineering. This dissertation discusses a survey of equipment reliability in a reliability and qualification laboratory that tests and simulates the operating conditions found in the environment of the oil and gas chain. From this, the determined problem was identified based on the following question: what are the potential failures and how to expressly calculate the reliability of the equipment in this laboratory, since we have a shortage of data on asset failures in adverse conditions of pressure, flow and temperature arranged in this environment? The results will be reached from the general objective, which proposes to identify the failure rate resulting from the eduction of the opinion of the specialists using the Delphi model to determine the reliability in the area of tests with liquids of this qualification and reliability laboratory.
