This work was realized in Refinería Costarricense de Petróleo (RECOPE), specifically in the department of “Programación y Control de mantenimiento” it is based on the Reliability Centered Maintenance (RCM) this methodology is used to define preventive maintenance manuals for the pumping equipment of Off Site area, with the main objective to improve the operational reliability and availability of these equipment. Off Site area has a main function to perform all the movements of petroleum products to the sales department, circulation between tanks, asphalt discharge, and dosage of dyes. Products like asphalt are constantly recirculated, since their chemical and physical composition should not be stored without movement or at room temperature, the pumps responsible for these movements are within the area Off Site as well as petrol pumps, diesel, bunker, naphtha, liquefied petroleum gas, dyes, IFO's and gasoline plane. In the area of Off Site, currently there are about 80 pumping equipment, including centrifugal and positive displacement pumps, electric motors, combustion engines, speed reducers and steam turbines. Initially work orders of the first half of 2014 were analyzed in order to know which equipment had more problems and required more maintenance later criticality analysis is performed to determine the equipment they must first be included in the analysis. The selection of equipment to study was made based on the criticality analysis, however subsequently obtained maintenance plans for such equipment were evaluated and applied to other equipment Off Site As it’s required by RCM methodology this analysis was reviewed and discussed with members of the working group, for it was discussed with staff maintenance workshops the probability of occurrence of each failure mode and proactive actions generated and their respective application frequencies. The work includes technical specifications for critical equipment and preventive maintenance plan, with details of the inspections carried out by maintenance personnel also detail areas for improvement including training of technicians.
