ABSTRACT

The air hose failure as a component of Mobile Air Compressor (MAC) was monitored in the operation of Obrikom gas plant for a period of four years and downtime, mean time between failure, failure rate, reliability, unreliability and availability values were evaluated in this investigation. The air hose as a component in the mobile air compressor plays a major role in the day- to – day operation of gas plant facility. The downtime increases from 68hrs to 79hrs for period of four years sampling with 68hrs for first year sampling, 72hrs for second year sampling, 75hrs for third year and 79hrs for fourth year sampling. The mean time between failures was evaluated for each of sampling period and the following results were obtained as 496hrs, 397.7hrs, 324hrs and 235.2hrs for the period of four years sampling and the failure rate values were 0.000684, 0.000799, 0.000913 and 0.00114. The investigation demonstrates decrease in the mean time between failure and increase in the failure rate as well as the reliability of air hose mobile air compressor decreases with increase in sampling time of the year as the cost of unreliability increases as the year of sampling increases. This investigation addresses the usefulness of air hose component in mobile air compressor and the need for continuous monitoring for the purpose of preventive maintenance as well as increase production.
