Abstract

Heating, Ventilation, Air Conditioning (HVAC) is a system keeps people healthy by filtering clean indoor air that and maintained the humidity levels at optimal comfort levels. The failure of the compressor results in the breakdown of the entire system. Multi criteria decision making (MCDM) focused with constructing and addressing multi criteria decisions and planning issues on to failure that occur on the compressor. In this reports, Failure Mode Effect Analysis (FMEA) was applied in order to identify the most significant failure mode using the Risk Priority Number (RPN) score. Then, the highest risk priority number score was compared between the compressor used in oil and gas platform in Terengganu with other failure occur in other wide industry application. The information identified of compressor was gathered on the maintenance reports HVAC Experts Sdn. Bhd. The highest failure modes occur in offshore analysis is crankshaft with 17% due to chlorine from the sea water caused a moderately acidic at the base component while other application was the pistons and bearing. Additionally, the highest failure mode with risk priority number score above 120. As a recommendation, Risk Based condition maintenance is suggested as it reduce the risk according from higher likelihood breakdown to lowest and are cost-saving.
