ABSTRACT:
This article proposes an integral methodology based on the failure mode analysis for problem resolution related to the reliability of industrial assets. The failure mode is an event that precedes the physical occurrence of a failure and, therefore, the loss of function in the asset in question. For this reason, the identification and analysis of the modes is the starting point for the proposed methodology. The following methodological proposal seeks to integrate and align different reliability and maintainability techniques, currently used individually to give support to asset management.
The objective of the proposed methodology is the design of a logical sequence of steps for problem analysis and subsequent proposal for solutions and/or improvements. This methodology takes into account, in addition, key aspects such as: hierarchization of equipment, identification of root causes and optimal solutions. The paper is structured as follows: section 2 performs a revision of the principal techniques applied in the area of reliability. Section 3 describes step by step the methodological proposal through a logical sequence of stages. Later, section 4 presents a real case application of the proposed methodology developed in the Arauco Cellulose Plant, Plant Trupan-Cholguan, in Yungay, Chile. Concretely, the methodology proposed applies to problem resolution in fluidized bed combustion. Last, the results and conclusions of the completed investigation are shown.
