Elaboración de un protocolo para el monitoreo de vibraciones estructurales en motocompresores horizontales para extracción de gas

Abstract

This research developed a structural vibration monitoring protocol for horizontal engine-compressor units used in gas extraction processes, aiming to strengthen predictive maintenance strategies and prevent failures associated with structural integrity issues. The methodology included the review and analysis of international standards such as the European Forum for Reciprocating Compressors guidelines and applicable International Organization for Standardization standards for vibration diagnostics, as well as the characterization of the main structural excitation sources in this type of equipment. Based on this, a measurement, data acquisition, and analysis protocol was designed using portable instrumentation and spectral analysis techniques. Subsequently, the protocol was implemented in a real case study, enabling the identification of structural resonance and mechanical looseness in the skid and piping system. Corrective actions derived from the diagnosis significantly reduced vibration levels at critical points, validating the effectiveness of the proposed protocol as a technical tool for decision-making in industrial predictive maintenance programs.
