Resumo: | The purpose of this article was to propose a maintenance strategy and a set of improvement actions for increasing the availability in a compression station of waste gases from the petroleum distillation process, composed of two alternative compressors A and B in a plant of the oil industry. The research method was the quantitative modeling. The methodology includes the calculation of the current availability and suggesting actions to raise it. Time to repair (TTR) and time between failures (TBF) were modeled for the individual compressors and for the gas compression station as a whole. With the average values of the models (MTBF and MTTR) were calculated individual availabilities of A and B (32.4% and 83.3%, respectively) and global, 96.7%. The data were collected from the company's information system. By the form factors associated with TBF, it was possible to affirm that, despite operating for over twenty years, both machines are in the premature failures phase. This fact is due to the exchange of raw materials, which occurred about five years ago: the plant proceeded to process heavier oil, originated from the pre-salt layer, for which the installation was not designed. Such divergence may be characterized as a design fault, associated with the corrective maintenance strategy. Finally, a list of improvements projects was presented to increase the availability of the post and terminate the phase of premature failures. |

O método de pesquisa foi a modelagem quantitativa. A metodologia incluiu o cálculo da atual disponibilidade e a sugestão de ações para elevá-la. Foram modelados os tempos até o reparo (TTR) e até a falha (TBF) dos compressores individuais e do posto de compressão de gases como um todo. Com os valores médios dos modelos (MTBF e MTTR) foram calculadas as disponibilidades individuais de A e B (32,4% e 83,3%, respectivamente) e do conjunto, 96,7%. Os dados foram coletados do sistema de informações da empresa. Pelos fatores de forma das distribuições associadas aos TBF, foi possível afirmar que, apesar de operarem há mais de vinte anos, ambas as máquinas se encontram na fase de mortalidade infantil. Tal fato se deve à troca de matéria-prima ocorrida há cerca de cinco anos: a planta passou a processar óleo mais pesado, originado do pré-sal, para o qual a instalação não foi projetada. Tal divergência pode ser caracterizada como falta de projeto, o que remete à estratégia de manutenção corretiva. Por fim, uma lista de melhorias corretivas de projeto foi apresentada para aumentar a disponibilidade do posto e encerrar a fase de falhas prematuras.Associação Brasileira de Engenharia de Produção2016-03-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfaudio/mpeghttps://www.producaoonline.org.br/rpo/article/view/190510.14488/1676-1901.v16i1.1905Revista Produção Online; Vol. 16 No. 1 (2016); 77-103Revista Produção Online; v. 16 n. 1 (2016); 77-1031676-1901reponame:Revista Produção Onlineinstname:Associação Brasileira de Engenharia de Produção (ABEPRO)instacron:ABEPROporhttps://www.producaoonline.org.br/rpo/article/view/1905/1368https://www.producaoonline.org.br/rpo/article/view/1905/1369Copyright (c) 2016 Revista Produção Onlineinfo:eu-repo/semantics/openAccessSantos, Nilis Adriano dosSellitto, Miguel Afonso2016-03-15T12:00:21Zoai:ojs.emnuvens.com.br:article/1905Revistahttp://producaoonline.org.br/rpoPUBhttps://www.producaoonline.org.br/rpo/oai||producaoonline@gmail.com1676-19011676-1901opendoar:2016-03-15T12:00:21Revista Produção Online - Associação Brasileira de Engenharia de Produção (ABEPRO)false |
