The maintenance strategy is becoming increasingly critical with the increasing competition in the oil and gas industrial environment due to hundreds pieces of equipment, which operate continuously under rigorous operational conditions resulting from over pressures and fluctuated temperatures. Many pieces of equipment usually subject to an inspection and maintenance during normal operation of a plant. However, others pieces cannot be inspected and maintained during normal operation of plant unless plant facilities are totally subjected to shutdown to avoid huge production losses in the company. Therefore, the study proposed in this work was to select appropriate maintenance strategies that could be divided into four alternative: Preventive Maintenance (PM), Corrective Maintenance (CM), Predictive Maintenance (PdM) and Turnaround Maintenance (TAM) to arrange inspection and maintenance scheduling for all pieces of equipment in the oil and gas plant based on four criteria: safety, production, cost and availability associated with goal of Analytical Hierarchy Process (AHP) approach. The result is to decrease in the cost of maintenance and production losses and maximize availability and efficiency of oil and gas plant facilities.
