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.

Baseline scans of a vessel are undertaken when it is known to be clean, operating normally, and in good mechanical condition. They are often used for comparison purposes on future troubleshooting scans. Any anomaly, or abnormal absorption observed on a baseline scan, that cannot be explained by a visible external interference or by something indicated in the column drawings, may be able to be eliminated as a potential problem area in future troubleshooting scans.
