One of the oldest and thinnest sets of coke drums in operation in the world suffered accelerated deterioration, unpredicted cracks, and loss of containment. After utilizing a rigorous strategy of inspections, assessments, and long-term repairs over the last nine years, the reliability and safety of operating these drums improved to the point that replacement plans were canceled and the time between turnarounds is being considered for an increase. In this presentation, we describe the management strategy that was used and show its impact on the reversal of deterioration trends which appears to be unique in industry.
