Vibration Analysis and Condition Monitoring Of a Marine Gas Turbine for Efficient Performance

Abstract

The vibration analysis and condition monitoring of a marine gas turbine for efficient performance has been conducted. The work look at vibration displacement amplitude in which collations of data were done through direct measurement from the real gas turbine and generator performance logsheet. The gas turbine under investigation is the Trans- Amadi Gas Turbine utilized for power generation. The procedural process for the vibration data collection continues for twenty-five weeks in which each week a minimum of five days hourly readings were taken and the average taken and recorded for that week. The revelations from the study reveals that vibration influence the performance of the gas turbine. Precisely, the number of deficiency apportioned to the gas turbine is a function of the vibration displacement amplitude on the rotor-shaft and the four bearings. Observably, the bearings at the turbine bears very high force as a result of the power generation thereby bring about very high vibration displacement amplitude. The vibration appraisal also displays that using vibration for diagnosis in machinery like gas turbine is the best effective way for detecting together with identifying deficiency in bearing thereby making it very vital in order to debar ruinous breakdown of the gas turbine plant. It is recommended that performance appraisal and condition monitoring of the plant show be done steadily in order to avoid unscheduled shutdown.
