In this paper, an opportunistic maintenance approach has been studied on a reciprocating compressor, which consists of series connected structure. When the system is down, either under corrective or preventive maintenance, the opportunity to replace even preventive non-failed subassemblies is considered. The optimization of opportunistic action depends upon the failure cost, which again depends upon the minimum cost of opportunistic action. The impact of opportunistic maintenance on the Life Cycle Cost (LCC) of a reciprocating compressor has been simulated. The case study result shows the reduction of INR 12,541,750 in LCC of a reciprocating compressor and ensures the required level of operational availability, when the opportunistic maintenance is incorporated in its traditional maintenance approach.
