Análisis y propuesta de mejora de la confiabilidad humana en la operación de los grupos electrógenos Wartsila 16V32LNGD ubicados en La Central de Generación Secoya.

Abstract

The objective was to carry out an analysis and proposal of improvement of the human reliability in the operation of the generators Wärtsilä 16V32LNGD located in the Central of generation Secoya. By means of surveys carried out on the field personnel, the elements that affect human reliability, as well as occupational safety and health, were established. To determine failures over a period of 6 months (4000 hours of operation) and the root cause analysis was performed. To determine the percentage of human reliability that affected corrective maintenance, being 30,37% at the beginning and 58,21% after the improvement proposal, where an increase in human reliability is observed in 27,84%, it is concluded that improving human reliability reduces corrective maintenance and improves the operation of the generating sets. As a complement, the statistical test was performed by the “Chi Square” test to determine the hypothesis, obtaining a value of Square Chi (28,71)>(11,07) Chi Square of the table, with a value of significance of 0,05; The proposed alternative hypothesis was found to be acceptable. It is recommended that a comprehensive annual training and training program be established for all staff as an organizational policy.
