Pre-turnaround scans are very useful tools for facilities to utilise for planning turnaround projects. They can indicate some damage within a vessel, allowing for parts to be ordered and onsite ahead of time. They can also indicate an operational issue, which can be corrected without an entry into the vessel. If required they can indicate that the vessel is healthy and no work is needed on it at this time.

Advantages of PreTurnaround and Baseline Scans

Are you planning a scheduled turnaround and want to know the advantages of scanning before and after your planned turnaround?
A Tru-Scan™ or Tru-Grid™ Scan will assist in defining and developing a turnaround critical path project scope at an early stage ensuring that your turnaround meets your goals. The most common use of gamma scans is to give process engineers and operations an online tool that results in understanding how a column is performing. This data can be used in advance of a turnaround to identify tray or packing damage and other process problems without having to shut down the column for internal inspections. These results will fully prepare turnaround planners with the knowledge they need for critical path decisions that must be made prior to a shutdown. At other times the results from a Tru-Scan™ or Tru-Grid™ Scan can either justify an unscheduled shutdown or identify options that will enable a plant to continue operating until the next scheduled shutdown.

Measuring the depth of refractory inside steel walls

Every refinery invests a tremendous amount of time and money in planning a unit turnaround. Scheduling of the tasks, manpower and equipment has to be detailed and thorough. In order to plan, information is needed about the process system so that critical tasks can be planned to meet turnaround time constraints. Some of this condition-based information is gathered using tools such as gamma scans, radiography, ultrasonic probes, vibration monitors, acoustic sensors, and other non-destructive techniques whilst the process is still operating. It is vital to be aware of any internal damage to distillation columns, heat exchangers, reactors, and other vessels to avoid surprises that can disrupt the turnaround schedule. Each day of downtime is a day of lost production, so it is critical that a turnaround is not extended due to unexpected repair work.
