“…From the works, the numerical results denoted that the vibration problem may be accredited from the pressure nonuniformity of the gas inside the pipes, low overall stiffness of the piping system and the first-order structural resonance occurred on the thermowells. [6] also utilized vibration properties to investigate operating failures in turbocharger centrifugal compressor by simulating damage scenarios of the blades component, aiming to establish a quantitative comparison system between vibration analysis and acoustic analysis. Vibration studies hold a significant role in the engineering field, simultaneously providing a great area of discipline to be explored.…”

Smooth plant production is utmost expected by plant owners since any unplanned shutdown is very much undesirable as it may incur loss of company’s profits and other repercussions. Critical operational assets such as rotating machineries and their components, e.g., motor, pump, compressor, and turbines are crucial to be monitored in ensuring continuous operation of the plant. Therefore, vibration being one of the elements in predictive maintenance is much needed. This paper addressesthe monitoring and findings for predictive maintenance on high vibration of a make-up gas compressor in one of the oil & gas and petrochemical plant in Malaysia. The conventional vibration measurement using vibration analyzer was utilized to identify the severity of the machine vibrations through the overall vibration value obtained on the motor and compressor. A specialized vibration measurement technique, namely, Operational Modal Analysis (OMA) was further deployed to verify the presence of resonance on the equipment by obtaining its dynamic characteristics, i.e., natural frequency and mode shape. The findings showed clear indication of resonance occurrence as similar frequency (112 Hz) was identified from both vibration measurement and operational modal analysis.
