El mantenimiento en la confiabilidad y disponibilidad de un sistema de generación de vapor // Maintenance on the reliability and availability of steam boiler systems
Abstract
El presente trabajo tiene como objetivo revelar y agrupar los principales hallazgos de seguridad
detectados en Sistemas de Generación de Vapor, SGV, que influyen en su confiabilidad y
disponibilidad y son causados por debilidades en la función mantenimiento. Los hallazgos han sido
identificados mediante la aplicación de Técnicas de Identificación de Peligros, TIP, como Revisiones
de Seguridad, Análisis HAZOP y Análisis Qué pasa si..?, entre otras metodologías y técnicas
disponibles, a más de una treintena de instalaciones donde los SGV han cumplido funciones tanto de
apoyo a la producción como a los servicios. Agrupar y analizar estos hallazgos, problemas o
desviaciones de seguridad han revelado que, independientemente del grado de cultura de seguridad
que presente la instalación objeto de estudio, tienen un mismo origen y requieren de acciones
similares para su gestión.
Palabras claves: mantenimiento, confiabilidad, disponibilidad, seguridad, caldera, generación de vapor.

Abstract
This paper has as objective to develop and to group the main findings of safety detected in Steam
Boiler Systems that influence in its reliability and availability and they are caused by weaknesses in
the function maintenance. Findings have been identified by means of the application of Hazard
Identification Techniques, HIT, like Safety Revision, HAZOP Analysis, What if..? Analysis and others
methodologies and techniques available, applied to more than a thirty of where the Steam Boiler
Systems have fulfilled functions in support to the production or services. Grouping and analyzing
these findings, problems or deviations of safety have revealed that, independently of the grade of
safety culture presents in the facility, they have common causes and they require of similar actions for
their management.
Key words: maintenance, reliability, safety, availability, steam boilers.
