Reducing Failure Rate of Block and Control Valves Using Lean SixSigma Based Approach

This study investigates the causes of failures in block and control valves, identifying four main factors: inappropriate pressure setting, inadequate preventive maintenance, valve design flaws, and the presence of foreign particles in wells. Based on these findings, it proposes an implementation plan for process improvement, comprising short and long-term solutions tailored to address each root cause. Recommendations include consulting material specialists for proper material selection, upgrading valve materials, ensuring spare parts availability, emphasizing rig cleaning, and updating preventive maintenance procedures. Implementation of these measures is expected to lead to a 50% reduction in the failure rate of both block and control valves, resulting in significant cost savings and reduced production downtime.
