The services included complete RCM study, preparation of facility change recommendations, standardized operating instructions for plant production team and uploading of all the data into Daleel ERP system. The challenges that were faced along the way include missing engineering specifications, unavailability of OEM manuals and missing information regarding engineering design parameters.


The scope of work included carrying out RCM Study for process plant, gathering stations, custody metering Units and Well sites associated with Daleel production facilities. Milestones, thus covered in this RCM Study, are development of Asset register, Failure mode effect and criticality analysis (FMECA), Recommendation of Preventive maintenance schedules and routines, preparation of maintenance craft procedures and Bill of materials, preparation of facility change recommendations, standardized operating instructions for plant production team, deployment of data in Daleel ERP system, implementation of RCM study using VAIL-Plant software EIRMS module and final RCM report. The scope of work included all equipment including electrical, mechanical & instrumentation.
