Turnaround Duration Study

Gain visibility into top-performing turnarounds and access the tools you need to enhance your turnaround performance.

Our Worldwide Refining Turnaround Duration Performance Analysis (Turnaround Duration Study) can teach you to better plan, execute, and budget turnarounds, and highlights opportunities for performance improvement. Learn where your turnaround performance excelled or fell short by comparing it to others in the industry. The study can help you better manage the total length of downtime, improving time off from production and generating more profit for your refinery.

We carefully evaluate system-wide data that has been collected and normalized using Solomon’s trusted methodology and metrics. Study results are presented on a refinery basis and for each major unit in the study, with regional comparisons where possible. Durations of the five components (listed at right) are reported against a standard, which has been developed based on the capacity of the process unit and the interval between turnarounds from our latest Fuels Study data. Other relevant information is also presented, such as key drivers for turnarounds and methods used for preparation for entry.

In a recent study, results showed that the top five performers achieved 14 fewer turnaround days than the study average. Additionally, the top five performers achieved their planned turnaround duration goals, while the average study performers lagged in their plans by more than 20%.

Establish realistic and competitive duration targets for your next turnaround.
