Evaluation of turnaround maintenance practice effects in the process industry

Abstract

Process industry such as the petrochemical industry is a kind of industry where the production performance depends on production equipment and assets. Thus, preventive maintenance becomes a very important way to achieve sustainable production in the process industry. The effectiveness, efficiency, reliability and maintenance of the equipment are vital for the uninterrupted, continuous and efficient operation. Turnaround maintenance (TAM) plays the most important role of preventive maintenance activities because it is an essential activity of maintenance in the process industry to improve the availability and reliability of the assets includes plant facilities, equipment and machinery. This study evaluates the effect of Turnaround Maintenance on the condition of the assets in the process industry using the statistical method. The significant variables used to analyze the effect of TAM are Plant Availability and Downtime Loss. The result shows that the correlation value between TAM occurrences with the increasing of availability is 0, 315 and with the increasing of downtime loss is -0, 818. The correlation value proves that TAM have a significant effect to increase the availability of the plant and to decrease the downtime loss in the real process industry practice.
