Abstract
Regular life cycle of any equipment undergoes various stages starting with R&D phase, concept design, procurement, construction, initial operation, beneficial operation, mature operation, and at last, remnant life stage. Cost involvement accordingly varies per stage, which can be demonstrated with reference to fig. 1. Anticipated cost for an equipment at the remnant life stage is at highest compared to other costs during equipment life, which shall be assessed thoroughly to sustain optimum operation in line with maintaining reasonable expenditure. The scope of RLA was to assess life expectancy, performance, technical integrity, CAPEX, and emission across ADMA OPCO's existing critical list of rotating machineries. Approach taken to conduct the study and compile the results was through various interviews, site visits, data reviews / analysis, and collecting team experiences. As a result from RLA, ADMA OPCO highlighted major areas of concerns and were given a better position to develop a well-established CAPEX estimate and replacement scope for existing rotating machinery fleet.
