This paper makes a link between opportunistic maintenance literature and warranty analysis of a power plant. A new plant warranty maintenance tasks are observed over a two year period. The main aim is to see how opportunistic maintenance could be incorporated when the warranty period has elapsed. The paper examine the warranty period maintenance task list and propose adequate methods for assessing opportunistic maintenance as a preventive maintenance task in order to ensure reliability and availability of the plant equipment. Statistical approach is used to give an insight to the plant equipment status and a modeling approach is proposed to also assess maintenance information defined by experts in the context of actual operating regimes. This study focuses on the power plant¿s critical equipment. Failure Mode and Effect Analysis (FMEA) is conducted on the power plant Booster Fans. This gives an insight about equipment failure mode patterns and maintenance requirements. A simulation example is presented based in the failure modes results obtained and a graphical display of optimum preventive maintenance schedule cost curves is also presented.
