Abstract

This paper discussed the preventive maintenance planning in one of the process plant in Bintulu Sarawak which is SHELL MDS SDN.BHD. Preventive maintenance (PM) planning is method in which the maintenance activities are planned and scheduled based on predetermined counter intervals in order to prevent breakdowns and failures from occurring. This study investigates the effect of the maintenance performance in the Hydrogen Manufacturing Unit (HMU) and to estimate the total cost incurred within the maintenance planning time horizon. The scope of this study is to investigate the effect of maintenance performance related to the size of the labor force, preventive frequency and spare part inventory and the budget estimation that include the economic losses, PM cost, labor cost and inventory cost. Begin with process flow diagram (PFD) of the plant to determine the equipment that needed in this research. By identify the failure mode of the equipment, all the related parameter will be listed out such as the rate of failure, rate of PM, Mean Time Between Failure (MTBF) and also the rate of repair. From these parameters, the maintenance planning can be scheduled and the data can be simulated using the selected model. The application of the model resulted in the prolonged of the MTBF for each equipment, increases in the availability of the machine under the control parameters and the frequency of equipment down for PM increases to reduce the failure. A good preventive maintenance planning is found to decrease the system failure and the downtime. The most important is the availability of the equipment which to be always considered in all calculations.
